I'm trying to update the source of an iFrame when a button is clicked on the page. However, nothing seems to be happening...
.ASPX:
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always">
<ContentTemplate>
<div class="accountInfo">
<p class="submitButton">
<asp:Button ID="ValidateButton" runat="server" Text="Validate" OnClick="SubmitSponsor" />
</p>
</div>
<iframe runat="server" id="PayPalFrame" height="150px" width="100%" frameborder="0"></iframe>
</ContentTemplate>
</asp:UpdatePanel>
Code Behind:
protected void SubmitSponsor(object sender, EventArgs e)
{
var driver = new Driver();
var isvalid = driver.IsAppValid(URL.Text, APILINK, Connstring);
if (isvalid)
{
PayPalFrame.Attributes.Add("src", "http://www.google.com");
URLInvalid.Visible = false;
}
}
I've also tried:
PayPalFrame.Attributes["src"] = "http://www.google.com"; and still nothing.
I have tested your code, and it works in a sample project:
ASPX:
<form id="form1" runat="server">
<div>
<asp:ScriptManager runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always">
<ContentTemplate>
<div class="accountInfo">
<p class="submitButton">
<asp:Button ID="ValidateButton" runat="server" Text="Validate" OnClick="SubmitSponsor" />
</p>
</div>
<iframe runat="server" id="PayPalFrame" height="150px" width="100%" frameborder="0">
</iframe>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
Codebehind:
public partial class UpdatePanelIFrameTester : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void SubmitSponsor(object sender, EventArgs e)
{
bool isvalid = true;
if (isvalid)
{
PayPalFrame.Attributes.Add("src", "http://www.ironworks.com");
}
}
}
I would inspect your code and ensure nothing is causing your page to refresh/perform a full postback (I changed the URL as google will not allow you to view it in an iframe under standard conditions).
I believe you have to remove the src attribute and then re-add it, for this to work. Not sure why this is, but I remember doing it the last time I worked with update panels. Perhaps it's because the src attribute always already exists?
Anyway, here's some sample code: how to change the src attribute in iframe.

I built the search logic with textbox search. However, While I search and the query is being executed I want the spinner to run while the results are fetched.
Here's my code : -
I tried both way but the spinner does not show.
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" ClientIDMode="Inherit" UpdateMode="Always">
<ContentTemplate>
<asp:TextBox runat="server" ID="Searchtext" OnTextChanged="Searchtext_TextChanged" AutoPostBack="true"></asp:TextBox>
<div id="spinner" runat="server">
<img src="././spinner.gif/>
<div>
</ContentTemplate>
</asp:UpdatePanel>
<script type="text/javascript">
function show()
{
$('#spinner').css("display", "block");
}
</script>
protected void Searchtext_TextChanged(object sender, EventArgs e)
{
spinner.Visible = true;
searchLogic();
spinner.Visible = false;
}
Other way : -
<div id="spinner" style="display:none;">
<img src="././spinner.gif/>
<div>
public void searchLogic()
{
sqlLogic(); // Queries and Results
}
protected void Searchtext_TextChanged(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "MyFunction", "show()", true);
searchLogic();
}
If I set run at server or not, when I search it shows waiting in chrome. But spinner is not fired. What I am doing wrong?
I realized that the best way to solve it using Asp:UpdateProgress and I solved it.
Thanks op's.
Scenario: I have a modal-style div that will be shown when the user clicks a button. At the time the div is shown, I need to get some data from the back-end to fill in some fields. Additionally, I'd like to use the jQuery method I use for all my modal windows (fades in the modal div, displays a background div as well as enabling the use of ESC key or "click offs" to close the modal).
It looks something like this:
<asp:ScriptManager ID="sc" runat="server" />
<asp:UpdatePanel ID="updForm" runat="server">
<ContentTemplate>
<h4>Testing jQuery calls combined with code behind actions</h4>
<div class="pad-content">
<asp:LinkButton ID="lnkShowIt" runat="server" OnClick="lnkShowIt_Click" Text="Load Form" OnClientClick="showForm()" />
<asp:Panel ID="pnlPopup" ClientIDMode="Static" runat="server" CssClass="box-modal" style="width:500px;display:none;z-index:1001">
<div class="header">Edit Estimate X</div>
<div class="content">
<div class="window">
<h5>Test Form</h5>
<asp:TextBox ID="tbxTime" runat="server" />
<br />
<asp:TextBox ID="tbxText" runat="server" Width="150px" />
<br />
<asp:LinkButton ID="lnkValidate" runat="server" CssClass="link-button-blue" Text="Validate" OnClick="lnkValidate_Click" />
</div>
</div>
</asp:Panel>
</div>
</ContentTemplate>
</asp:UpdatePanel>
<div id="backgroundPopup"></div>
So ... lnkShowIt calls both the jQuery (which will show pnlPopup) as well as the C# (which will populate tbxTime).
jQuery method actually just calls another method from a common js library I have that does the modal window stuff - I don't think that actual code is the problem but here is the simple function used for this page:
<script type="text/javascript" language="javascript">
function showForm() {
loadPopup('#pnlPopup');
}
</script>
Code behind methods look like this:
protected void lnkShowIt_Click(object sender, EventArgs e)
{
tbxTime.Text = System.DateTime.Now.Second.ToString();
}
protected void lnkValidate_Click(object sender, EventArgs e)
{
if (tbxTime.Text == tbxText.Text)
{
Response.Redirect("DynamicBoxesWithJQuery.aspx?mode=success");
}
else
{
tbxText.Style["border"] = "1px solid red";
}
}
I'm able to generate some level of success by doing the following but it seems like just a major hack and I have to assume there's a better approach:
protected void lnkShowIt_Click(object sender, EventArgs e)
{
tbxTime.Text = System.DateTime.Now.Second.ToString();
ScriptManager.RegisterStartupScript(this, this.GetType(), "OpenEditor", "<script type='text/javascript'>loadPopup('#pnlPopup');</script>", false);
}
protected void lnkValidate_Click(object sender, EventArgs e)
{
if (tbxTime.Text == tbxText.Text)
{
Response.Redirect("DynamicBoxesWithJQuery.aspx?mode=success");
}
else
{
tbxText.Style["border"] = "1px solid red";
ScriptManager.RegisterStartupScript(this, this.GetType(), "OpenEditor", "<script type='text/javascript'>loadPopup('#pnlPopup');</script>", false);
}
}
It seems like it should be easier than this, but the way the UpdatePanel keeps redrawing (and thus resetting the display:none on pnlPopup) is really causing me fits.
Thanks in advance
Solution I just found: putting the LinkButton in its own UpdatePanel and then the form in its own UpdatePanel and making sure the div that is the actual popup box is not in an UpdatePanel at all.
<h4>Testing jQuery calls combined with code behind actions</h4>
<div class="pad-content">
<asp:UpdatePanel ID="updLink" runat="server">
<ContentTemplate>
<asp:LinkButton ID="lnkShowIt" runat="server" OnClick="lnkShowIt_Click" Text="Load Form" OnClientClick="showForm()" />

</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</asp:Panel>
</div>
Seems to do the trick without any Script Registers from the codebehind
Here's the markup:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div class="well well-large">
<form class="navbar-form pull-left">
<asp:FileUpload ID="test" runat="server" CssClass="input-small" />
<br />
<asp:Button ID="btnUpload" runat="server" Text="Upload" CssClass="btn" OnClick="btnUpload_Click" />
</form>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnUpload" EventName="Click" />
</Triggers>
</asp:UpdatePanel>
<asp:Panel runat="server" ID="panAlert" Visible="false">
<div class="alert alert-success" id="divAlert" runat="server">
<button id="Button1" runat="server" type="button" class="close" data-dismiss="alert">×</button>
You shouldn't see this message!
</div>
<asp:Panel runat="server" ID="panMarquee" Visible="true">
<div id="Div1" runat="server" class="progress progress-success progress-striped">
<div id="ProgressBar" runat="server" class="bar" style="width: 100%"></div>
</div>
</asp:Panel>
</asp:Panel>
When the btnUpload button is clicked, the server code is supposed to determine if the FileUpload control has a file. If it does, it will change the visibility of the Panel control to true. It works fine outside of the UpdatePanel.
Here's the server code:
protected void btnUpload_Click(object sender, EventArgs e)
{
this.SetMessage(Message.Success);
try
{
if (this.test.HasFile)
{
string filename = Path.GetFileName(GetUB04Doc.FileName);
//test.SaveAs(Server.MapPath("~/") + filename);
this.SetMessage(Message.Success);
}
}
catch (Exception ex)
{
//TODO: Do something with th exception
this.SetMessage(Message.Fail);
}
finally
{
//this.GetUB04Doc.Dispose();
}
}
private enum Message { Success, Fail }
private void SetMessage(Message msg)
{
if (msg == Message.Success)
{
this.divAlert.InnerText = "Well done! The document appears to have uploaded successfully. Please wait...";
this.divAlert.Attributes.Add("class", "alert alert-success");
}
else
{
this.divAlert.InnerText = "Oh snap! Something broke. Please contact IT right away.";
this.divAlert.Attributes.Add("class", "alert alert-error");
}
this.panAlert.Visible = true;
}
I tried putting the Panel in the ContentTemplate section as well, but the results were the same.
Any ideas on what I'm doing wrong here?
You should surround the area which you are modifying from an async postback in another UpdatePanel with UpdateMode is set to Conditional. Then update the other manually from codebehind:
<asp:UpdatePanel ID="panAlertUpdatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:Panel runat="server" ID="panAlert" Visible="false">
<!-- ....
codebehind:
// ...
this.panAlert.Visible = true;
panAlertUpdatePanel.Update()
Side-note: As #Belogix has already commented, you should use an AsyncFileUpload control in an UpdatePanel since a regular FileUpload control it's not supported with an asynchronous postback.
MSDN:
Controls that Are Not Compatible with UpdatePanel Controls:
...
FileUpload and HtmlInputFile controls when they are used to upload files as part of an asynchronous postback.
...
To use a FileUpload or HtmlInputFile control inside an UpdatePanel
control, set the postback control that submits the file to be a
PostBackTrigger control for the panel. The FileUpload and
HtmlInputFile control can be used only in postback scenarios.
you need to put PostBackTrigger instead of AsyncPostBackTrigger like this. <asp:PostBackTrigger ControlID="btnUpload" />
Im having a .Master page with
<asp:ScriptManager ID="ScriptManager" runat="server" />
<asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
<ContentTemplate>
<asp:ContentPlaceHolder ID="MasterIndhold_Member" runat="server">
</asp:ContentPlaceHolder>
And inside the ContentPlaceHolder I got an Panel with a FileUpload. The thing is that the FileUpload doesn't find the file. Here I want to add RegisterAsyncPostBackControl to the Scriptmanager, but how do I do this when the panel is on another page?
The nested page code looks like this
<asp:Content ID="Content3" ContentPlaceHolderID="MasterIndhold_Member" runat="server">
<asp:panel runat="server" ID="Panel_MyProfile_Member" Visible="false">
<asp:FileUpload ID="File1" runat="server" />
<asp:LinkButton ID="LinkUploadImageMember" runat="server" onclick="LinkUploadImageMember_Click">Upload</asp:LinkButton>
And the CodeBehind for the FileUpload Looks like this
protected void LinkUploadImageMember_Click(object sender, EventArgs e)
{
if (File1.HasFile == true)
{
if ((File1.PostedFile.FileName.EndsWith(".jpg")) || (File1.PostedFile.FileName.EndsWith(".jpeg")) || (File1.PostedFile.FileName.EndsWith(".png")))
{
byte[] input = File1.FileBytes;
Bruger.UploadImage(input, int.Parse(Request.QueryString["ID"]));
}
}
}
Please keep code examples to C# and ASP.NET as I'm new to this stuff ^^
Thanks
You could also use the ScriptManagerProxy class if you need a ScriptManager on your content page, but I'm not sure whether you need this at all. Do you really need an UpdatePanel on every content page? (because you declared it on the master page). I think it might be better to declare the UpdatePanel within the content page.
Try to define a trigger for your linkbutton, otherwise HasFiles is always false
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:PostBackTrigger ControlID="LinkUploadImageMember" />
</Triggers>
<ContentTemplate>
<asp:FileUpload ID="File1" runat="server" />
<asp:LinkButton ID="LinkUploadImageMember" runat="server" Text=" upload " />
</ContentTemplate>
</asp:UpdatePanel>
If you cannot remove the UpdatePanel from the Masterpage, you could expose a property on the masterpage that gives access the updatepanel, like this:
public UpdatePanel MyUpdatePanel
{
get { return UpdatePanel1; }
}
From the contentpage you can access the update panel and update the triggers programmatically:
protected void Page_Load(object sender, EventArgs e)
{
((Site)Master).MyUpdatePanel.Triggers.Add(new PostBackTrigger() {
ControlID = LinkUploadImageMember.UniqueID });
}
I have found many solution for my issue but none doesn't work in my scenario.
I have created a test project to demo my concept.
Basically, there is a page that host a user control...
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
<uc1:WebUserControl1 ID="WebUserControl11" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
WebUserControl1 has a dropdownlist and two other webusercontrols (to be displayed based on the selection of dropdownlist element) inside updatepanel as below.
<%# Register Src="WebUserControl2.ascx" TagName="WebUserControl2" TagPrefix="uc2" %>
<%# Register Src="WebUserControl3.ascx" TagName="WebUserControl3" TagPrefix="uc3" %>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:DropDownList ID="DropDownList1" runat="server"
OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"
AutoPostBack="True">
</asp:DropDownList>
<asp:Panel ID="pnlCreditCard" Visible="false" runat="server">
<uc2:WebUserControl2 ID="WebUserControl21" runat="server" />
</asp:Panel>
<asp:Panel ID="pnlGiftCard" Visible="false" runat="server">
<uc3:WebUserControl3 ID="WebUserControl31" runat="server" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
Code behind file for WebUserControl1 is .....
public enum PaymentMethod
{
CreditCard = 0,
GiftCard
}
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
BindPaymentMethods(Enum.GetValues(typeof(PaymentMethod)));
}
private void BindPaymentMethods(Array paymentMethods)
{
DropDownList1.DataSource = paymentMethods;
DropDownList1.DataBind();
if (paymentMethods.Length > 0)
{
DropDownList1.SelectedIndex = 0;
UpdateCreditOrGiftCardPanelVisibility();
}
}
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
UpdateCreditOrGiftCardPanelVisibility();
}
private void UpdateCreditOrGiftCardPanelVisibility()
{
if(DropDownList1.SelectedValue == Enum.GetName(typeof(PaymentMethod),PaymentMethod.CreditCard))
{
pnlGiftCard.Visible = false;
pnlCreditCard.Visible = true;
}
else if (DropDownList1.SelectedValue == Enum.GetName(typeof(PaymentMethod), PaymentMethod.GiftCard))
{
pnlCreditCard.Visible = false;
pnlGiftCard.Visible = true;
}
}
Now, the problem starts here...There is an external javascript file [JScript1.js] (embedded resource) which basically is used to display an alert box.
<script language="javascript" type="text/javascript">
window.onload = function() {
alert('creditcard form');
}
WebUserControl2.ascx.cs code behind is
protected void Page_Load(object sender, EventArgs e)
{
ScriptManager.RegisterClientScriptInclude(this.Page, this.Page.GetType().BaseType, "JScript1", Page.ClientScript.GetWebResourceUrl(this.Page.GetType().BaseType, "WebApplication1.JScript1.js"));
}
Alert window doesn't get displayed when I change the dropdownlist value. Even the script is getting registered three times (look in the firebug)
Need to use ScriptInclude instead of ScriptBlock as the original JS file is too big.
Can email the test app....
Thanks in Advance
After working around a bit, I found the solution.
I registered a ScriptManagerProxy in WebUserControl2.ascx
<asp:ScriptManagerProxy ID="ScriptManager1" runat="server" >
<Scripts>
<asp:ScriptReference Assembly="WebApplication1" Name="WebApplication1.JScript1.js" />
</Scripts>
</asp:ScriptManagerProxy>
Then on the code behind of the same control, added...
protected override void OnPreRender(EventArgs e)
{
base.OnPreRender(e);
ScriptManager.RegisterStartupScript(this, GetType(), "test", "doSomething();", true);
}
and the JScript1.js file looks like below.
function doSomething() {
alert('via dosomething control2 form');
}
Hope that helps. Though I had to litter around more in my practical scenario but this was certainly the way I got it working.
Thanks,
