I'm using jqueryui dialog function to display my registration form. I have no problem with opening the dialog and displaying register.aspx file in the div. However I have a register button which I would like to use to save the form data into the database. But when I click to that button, it closes the dialog box and redirects the page to the register.aspx. I tried to disable usesubmitbehavior but that didn't help it completely blocks the function of the button.
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" UseSubmitBehavior="False" />
protected void Button1_Click(object sender, EventArgs e)
{
firstName.Disabled = true; // this will be replaced for db data entry. It was just to see if the function is working or not.
}
Use OnClientClick to prevent the default behaviour of form submission upon click. If you do this you will need perform an ajax request to your server yourself.
<asp:Button ID="Button1" OnClientClick="handleRegistrationClientSide(); return false;" runat="server" Text="Button" UseSubmitBehavior="False" />
Otherwise wrap your dialog's inner content in an update panel, and trigger it on the button to cause an async postback.
<div id="myDialog">
<asp:UpdatePanel runat="server">
<ContentTemplate>
...
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Button1" />
</Triggers>
</asp:UpdatePanel>
</div>

Context of the problem:
I have a checkbox and a button. The button is disabled and colored grey upon the page load. I want the checkbox to enable and re-color the button if checked, and revert the change if unchecked. Think of it as a User Agreement page, where the user accepts the terms and needs to click on the checkbox to proceed.
There is a grid view and other components above the page that would break upon a postback, so searching online I found that I could use an UpdatePanel. Thought this would be more simple than writing jQuery for the checkbox, but it isn't working
Code:
ASPX
<asp:UpdatePanel ID ="upCheckbox" runat="server">
<ContentTemplate>
<asp:CheckBox ID="checkLabel" runat="server" OnCheckedChanged="checkLabel_CheckedChanged"/><asp:Label ID="AknowledgementLabel" runat="server" Text="Info is correct & Enable button"></asp:Label>
<br /><br />
<asp:Button ID="btnSubmit" Text="Submit Application" CssClass="jqbutton" OnClick="btnSubmit_Click" runat="server"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="checkLabel" EventName="CheckedChanged"/>
</Triggers>
</asp:UpdatePanel>
Code Behind:
protected void Page_Load(object sender, EventArgs e)
{
btnSubmit.Enabled = false;
btnSubmit.ForeColor = System.Drawing.Color.Gray;
}
protected void checkLabel_CheckedChanged(object sender, EventArgs e)
{
if (checkLabel.Checked)
{
btnSubmit.Enabled = true;
btnSubmit.ForeColor = System.Drawing.ColorTranslator.FromHtml("#336699");
}
else
{
btnSubmit.Enabled = false;
btnSubmit.ForeColor = System.Drawing.Color.Gray;
}
}
Problem:
The checkbox does not work and the submit button remains disabled. Not sure if I am using Update Panels for the appropriate purpose or if am missing something. Is it possible to accomplish this the way that I am trying to, or should I move on to jQuery?
You are missing AutoPostback="true" in your CheckBox control. By default it is set to false. With autopostback missing your event won't reach server side.
<asp:UpdatePanel ID ="upCheckbox" runat="server">
<ContentTemplate>
<asp:CheckBox ID="checkLabel" runat="server" AutoPostback="true" OnCheckedChanged="checkLabel_CheckedChanged"/>
<asp:Label ID="AknowledgementLabel" runat="server" Text="Info is correct & Enable button"></asp:Label>
<br /><br />
<asp:Button ID="btnSubmit" Text="Submit Application" CssClass="jqbutton" OnClick="btnSubmit_Click" runat="server"/>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="checkLabel" EventName="CheckedChanged"/>
</Triggers>
</asp:UpdatePanel>
I have put asp button in update panel and asp file uploader in outside of update panel in server side button click function i am geting file uploader empty.give me any idea..my code is below
<asp:FileUpload runat="server" ID="DecFormUpload"/>
<asp:UpdatePanel runat="server" ID="UpdateDecForm" UpdateMode="Conditional">
<ContentTemplate>
<asp:Button ID="DecFormUploadClick" OnClick="DecFormUploadClick_Click" OnClientClick="return DecFormUploadClick_Save();" runat="server" Text="Upload" />
</ContentTemplate>
</asp:UpdatePanel>
c# code
protected void DecFormUploadClick_Click(object sender, EventArgs e)
{
if(DecFormUpload.HasFile)//my problem is getting false here
{
}
}
This issue is due to that FileUpload needs a full postback, add the following just after your :
<Triggers>
<asp:PostBackTrigger ControlID="DecFormUploadClick" />
</Triggers>
Hope it helps
I have a button that opens a modal popup, but before I open the modal popup, I want my "OnClick" event for the "btnSaveAndScheduleTask" button to fire. I am using ASP.NET 4.5 / Visual Studio 2012 / HTML5 / CSS3
My aspx (snipet):
How do I get the codebehind OnClick event for my "btnSaveAndScheduleTask" button to fire? If the entire code would help figure it out, let me know, but I'm probably missing something simple (bear in mind that I want to be able to view all my asp controls from the C# codebehind):
<asp:Button ID="btnSaveAndScheduleTask" runat="server" CausesValidation="true"
OnClientClick="javascript:return validatePage();" OnClick="btnSaveAndScheduleTask_Click"
Font-Bold="true" Text="Schedule Task" />
<ajaxToolkit:ModalPopupExtender ID="mpeScheduleTask" runat="server" ValidateRequestMode="Enabled"
BackgroundCssClass="modalBackground" CancelControlID="btnCancSchedule"
PopupControlID="pnlScheduleTask" TargetControlID="btnSaveAndScheduleTask" DropShadow="true" >
</ajaxToolkit:ModalPopupExtender>
<div id="divScheduleTask" runat="server">
<asp:Panel ID="pnlScheduleTask" Height="310" Width="690" BackColor="#ece4e1" ForeColor="Black" runat="server" >
<asp:UpdatePanel runat="server" ID="udpScheduleTask" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lblTaskSch" Visible="false" Font-Bold="true" Text="Task Scheduling: " runat="server" />
<asp:Button ID="btnSaveSchedule" runat="server" OnClick="btnSaveSchedule_Click" Text="Save Schedule" />
</div><asp:Button ID="btnCancSchedule" runat="server" Text="Canc" />
</ContentTemplate></asp:UpdatePanel></asp:Panel></div>
I've left out most of the panel as it's huge... here is my validatePage() Javascript:
<script type="text/javascript">
function validatePage() {
//Executes all the validation controls associated with group1 validaiton Group1.
var flag = window.Page_ClientValidate('vTask');
if (flag)
//Executes all the validation controls which are not associated with any validation group.
flag = window.Page_ClientValidate();
if (!Page_IsValid) {
$find('mpeScheduleTask').hide();
}
return flag;
}
</script>
My aspx.cs code behind:
protected void btnSaveAndScheduleTask_Click(object sender, EventArgs e)
{
//do stuff
}
Remove TargetControlID="btnSaveAndScheduleTask" , give other dummy control's ID
So when button clicks, click will take user to server , in code behind you need to manually open popup.
This is given here...!!!!
http://www.codeproject.com/Tips/215040/ModalPopupExtender-from-Server-Side-Code
I would put the javascript to be called in the behind code in your button click..
protected void btnSaveAndScheduleTask_Click(object sender, EventArgs e)
{
// do stuff.
Page.ClientScript.RegisterStartupScript(this.GetType(), "Call my function", "validatePage();", true);
}
this is how I do most of mine. Hope this helps.
And your ASP should look like..
<asp:Button ID="btnSaveAndScheduleTask" runat="server" CausesValidation="true" OnClick="btnSaveAndScheduleTask_Click" Font-Bold="true" Text="Schedule Task" />
I already did search online, and try a few solutions provided, but none of them are working for me.
I have a button within a div. I am displaying the div within a jquery dialog. The button click doesnt work within the jquery dialog.
I have my code below :
aspx
<div id='one'>
<asp:LinkButton ID="ConfigureAlerts" OnClick="btnConfigureAlerts_Click" runat="server">Configure Alerts</asp:LinkButton>
</div>
<div id="ViewModalPopupDiv2">
<asp:UpdatePanel ID="UpdatePanel3" runat="server">
<ContentTemplate>
<asp:Panel ID="Panel2" runat="server" HorizontalAlign="left" ScrollBars="Auto">
<asp:Button ID="btnGetLogs" runat="server" Text="SendAlerts" OnClick="btnSendAlertEmail_Click"/>
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</div>
jquery
function ViewModelPopup2() {
$("#ViewModalPopupDiv2").dialog({
scrollable: true,
width: 800,
modal: true
});
}
aspx.cs
protected void btnSendAlertEmail_Click(object sender, EventArgs e)
{
// Code to send email
}
protected void btnConfigureAlerts_Click(object sender, EventArgs e)
{
ScriptManager.RegisterStartupScript
(this, this.GetType(), "callScriptFunction", "ViewModelPopup2();", true);
}
}
Please let me know what I need to do , to trigger the server control events .
I also had this problem with asp.net buttons and jQuery UI Dialog.
To solve it you need to set in your aspnet button the tag UseSubmitBehavior to false.
If UseSubmitBehavior attribute is set to true (this is the default value), the button will use the browser's submit mechanism (and jQuery Dialog UI is manipulating it), if UseSubmitBehavior is set to false, the button will use a client-side script that asp.net framework includes in the page to post to the form.
So your HTML should be like this :
<div id='one'>
<asp:LinkButton ID="ConfigureAlerts" OnClick="btnConfigureAlerts_Click" runat="server">Configure Alerts</asp:LinkButton>
</div>
<div id="ViewModalPopupDiv2">
<asp:UpdatePanel ID="UpdatePanel3" runat="server">
<ContentTemplate>
<asp:Panel ID="Panel2" runat="server" HorizontalAlign="left" ScrollBars="Auto">
<asp:Button ID="btnGetLogs" runat="server" Text="SendAlerts" OnClick="btnSendAlertEmail_Click" UseSubmitBehavior="false" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
</div>

This is the classic, thanks for moving my dialog jQuery, question.
jQuery UI for some reason moves your dialog code to the bottom of the html markup, outside of your form tag. You need to move the dialog back into the form with some more jQuery:
dlg.parent().appendTo(jQuery('form:first'));
where dlg is your jQuery.UI dialog object.
var dlg = $("#ViewModalPopupDiv2").dialog({
scrollable: true,
width: 800,
modal: true
});
dlg.parent().appendTo(jQuery('form:first'));
That should get things working for you again. Cheers!
If that doesn't work, try doing that in the open event:
open: function(type,data) { $(this).parent().appendTo("form"); }
I have two radio buttons both set as async triggers for an update panel and problem is that first time one is clicked the CheckedChanged event fires but then no matter which radio button is clicked the event never fires again.
Markup:
<asp:RadioButton ID="rdoDeliveryBilling" runat="server" Checked="true" GroupName="DeliveryAddress" Text="Deliver to this address" AutoPostBack="true" OnCheckedChanged="rdoDelivery_CheckedChanged" />
<asp:RadioButton ID="rdoDeliveryShipping" runat="server" GroupName="DeliveryAddress" Text="Deliver to a different address" AutoPostBack="true" OnCheckedChanged="rdoDelivery_CheckedChanged" />
<asp:UpdatePanel ID="panDeliveryAddress" runat="server">
<ContentTemplate>
...delivery details form controls and validators goes here...
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="rdoDeliveryBilling" EventName="CheckedChanged" />
<asp:AsyncPostBackTrigger ControlID="rdoDeliveryShipping" EventName="CheckedChanged" />
</Triggers>
</asp:UpdatePanel>
Code:
protected void rdoDelivery_CheckedChanged(object sender, EventArgs e)
{
...only code that enables/disables the delivery form controls and validators goes here...
}
I have set a breakpoint inside rdoDelivery_CheckedChanged and it only hits the first time.
Any ideas?
Looking at the source (in the browser), ASP.NET is only generating a post back function __doPostBack for the RadioButton controls which can possibly postback.
The first RadioButton control cannot postback (because it is already checked), and as such the __doPostBack is not generated.
A work around is to add the two RadioButton controls to another UpdatePanel, setting the UpdateMode to Always. This will cause the RadioButtons to be updated (whenever they trigger the other UpdatePanel) adding the __doPostBack function to the deselected RadioButton.
Example
<asp:UpdatePanel ID="UpdatePanelCheckBoxes" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:RadioButton ID="rdoDeliveryBilling" runat="server" Checked="true" GroupName="DeliveryAddress" Text="Deliver to this address" AutoPostBack="true" OnCheckedChanged="rdoDelivery_CheckedChanged" />
<asp:RadioButton ID="rdoDeliveryShipping" runat="server" GroupName="DeliveryAddress" Text="Deliver to a different address" AutoPostBack="true" OnCheckedChanged="rdoDelivery_CheckedChanged" />
</ContentTemplate>
</asp:UpdatePanel>
Hope this helps.
