I need to make a program click a javascript button for me in the webbrowser. Is this possible in any way? I want to accomplish this in C#
the button
INPUT id=str class=text style="TEXT-ALIGN: center" maxLength=4 size=3 value=558 INPUT onclick=doIt_new(1); id=strBtn type=button value=doIt
Yes its the default webbrowser object in visual studio
If you're using WinForm WebBrowser control - take a look at webBrowser.Document.InvokeScript method. It allows to execute JavaScript inside of a document, hosted in WebBroswer control.
string html =
#"<html>
<script>
function doIt_new(x){
alert(x);
}
</script>
</html>";
webBrowser1.DocumentText = html;
webBrowser1.DocumentCompleted += (s, e) =>
{
webBrowser1.Document.InvokeScript("doIt_new", new object[] { 1 });
};

Is it possible to call "button click event" in one web form ,from a button in another web form?
what actually i'm trying to do is, i've a link button in second form, when it is clicked, i want the first form to disply and also button in first form to be clicked.
can anyone help me do this?
I assume you are using jQuery and have basic knowledge of it. So do it this way:
<form id="form1" style="display:none">
<Asp:Button id="button1" onclick="alert('clicked')" >button1</Asp:Button>
</form>
<form id="form2">
<Asp:LinkButton url="javascript:void(0);" onclick="call1();">Link button1</Asp:LinkButton>
</form>
<script>
function call1()
{
$("#form1").show();
$("#button1").trigger("click");
}
</script>
Note: The asp markup written by me can give compilation errors, so please resolve those yourself. I put that just to give you the basic idea of how it is handled.
create a Delegate in WebForms (I have used in WinForms)
public delegate void LoginDelegate(string s);
loginAirLineDelegate = new LoginDelegate(DisableToolStripMenuItems);
public void DisableToolStripMenuItems(string s)
{
this.viewToolStripMenuItem.Visible = true;
this.bookingToolStripMenuItem.Visible = true;
this.existingUserToolStripMenuItem.Visible = false;
this.newUserToolStripMenuItem.Visible = false;
this.toolStripStatusUserID.Text = "USerID :- "+s;
this.LoginUserId = s;
}
I have passed the Delaqgte to other Form with Construtor as argumnet.
I can able to fire the delegate from the second form like this
logDelegate(textBoxUserName.Text);
Is it possible to fire an OnClick event upon clicking the asp:FileUpload button?
you can use flash code it will file uploader as button which is clickable. but for this you need to download swfupload.swf file.
<input type="file" id="uplaodExcel" name="uplaodExcel" />
following is the javascript code:
Sys.Application.add_init(function () {
HideError();
$("#uplaodExcel").makeAsyncUploader({
upload_url: 'EventName',//Event you want to occur on click
flash_url: '../Scripts/swfupload.swf',//flash file path that you download
button_image_url: '#Url.Content("~/Content/blankButton.png")',// for button style
file_size_limit: "10MB",
file_types: "*.XLS; *.xlsx", //File extension you can provide any
disableDuringUpload: 'INPUT[type="submit"]',
upload_success_handler: function (file, server_data, receivedResponse) {
var data = "";
try {
// you can add your code here
} catch (e) { }
}
});
});
according to w3schools an input of type file can support all standard events.
so what you can do is wirte to your control a javascript event for the click:
YOURCONTROL.Attributes.Add("onclick","YourLogic");
I am trying to slide down content within a div tag (red rectangle) when a user enters atleast one character in a textbox (green rectangle).
If no character is entered then the div content does not show.
Here is a pic of the aspx (design):
And this is the JavaScript I am using to try and achieve this:
function() {
$("#SubmitSection").hide();
inputOne = document.getElementById("<%= TextBox1.ClientID %>");
if (inputOne.value != "") {
$("#SubmitSection").slideDown('slow');
}
else {
$("#SubmitSection").slideUp('slow');
}
}
All the backend code works just fine but both the textbox and the div section show up when deployed.
if i got you right :
$("<%= TextBox1.ClientID %>").change(function(){YoursSlidingFunctionhere();})
.change()
You have to hook up to an event on the textbox. The onchange event only fires after the textbox loses focus, so I suggest the onkeyup event.
<asp:TextBox ID="TextBox1" runat="server" [...] onkeyup="updateSubmitSection()" />
You will have to name your function so that you can call it:
updateSubmitSection = function() {
$("#SubmitSection").hide();
inputOne = document.getElementById("<%= TextBox1.ClientID %>");
// ...
}
In addition to that, you need to call the function during the onload event of the page:
<body onload='updateSubmitSection()'>
The same solution using jQuery:
$(document).ready(function() {
updateSubmitSection();
$('#<%= TextBox1.ClientID %>').change(updateSubmitQuery);
}
You'll need to add this to a section of your javascript that is executed on initialization:
`$("#SubmitSection").hide();`
You could use the body onload attribute:
`<body onload="init()">
<script>
function init()
{
$("#SubmitSection").hide();
}
</script> `

Response.Redirect to new window
(20 answers)
Closed 7 years ago.
I am writing a project using ASP.NET C#.
I want to implement linkbutton click event to open new page in a new tab, but before I have to create new session variable. I have tried this:
protected void LinkButton_Click3(Object sender, EventArgs e)
{
string p_id = (sender as LinkButton).CommandArgument;
Session["p_id"] = p_id;
Response.Write("<script type='text/javascript'> window.open('details.aspx','_blank'); </script>");
}
But it doesn't work anyway.
Based on your comments, you should disable your popup blocker.
Try this, call this function on button click or document.ready only on page where you want to redirect from.
<script type="text/javascript">
function newTab()
{
if (opener.document.getElementById("aspnetForm").target != "_blank") return;
opener.document.getElementById("aspnetForm").target = "";
opener.document.getElementById("aspnetForm").action = opener.location.href;
}
</script
or add this to linkbutton html
OnClientClick="aspnetForm.target ='_blank';"
Sometimes it works for me to just declare whatever I would invoke dynamically from the administrated code into a javascript function and just call it from within with the
RegisterClientScriptBlock method in ClientScript class:
Daclare the window.open function:
<script type="text/javascript">
function SetRedirect(URI) {
window.open(URI, "Details", "menubar=no, location=no, resizable=yes, scrollbars=yes, status=yes, width = 1200, height = 600");
}
</script>
And from within the code behind class just a gateway caller to this function like:
void MessageGateway(string URI)
{
this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
"logCallBack", #"<script type=""text/javascript"">SetRedirect('" + URI + "');</script>");
}
And that's it, you may call this gateway with your stuff as normally you do,
MessageGateway(string.Format("../IRMQueryPO.aspx?id={0}", e.Item.Cells[2].Text));
You can try tweeking the "target" parameter with "_blank" in order to open a tab instead a window, it's just a matter of the flavor your solution points in.
I need to move this new button into this DIV that already exists. This seems to me like it should work but doesn't. What am I doing wrong?
Button button5 = new Button();
button5.Text = "Five";
button5.CssClass = "buttonCSS";
button5.Click += new EventHandler(button5_Click);
button5.ID = "button5";
this.Controls.Add(button5);
string myscript = #"
var navFooter = document.getElementById('NavFooter');
var button5 = document.getElementById('button5');
navFooter.Controls.Add(button5);
";
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyScript", myscript, true);
I know the two objects are being found. Any ideas?
(Note: I cannot use jQuery.)
Thank you.
Controls.Add() is C#, not JavaScript. To append an element to another element with JavaScript, use appendChild():
navFooter.appendChild(button5);
Why are you doing this through javascript?
If you change the containing <div> to a <asp:Panel>, then you can add the newly created button straight into this panel. The <asp:Panel> is rendered simply as a <div> html element, and you can add the CssClass to this to keep the styles the same.
Gives you overall greater control on the server side and you don't need to worry about the javascript. Especially since you are doing server side work anyway.
Just add runat="server" to the div, and add it in the code behind:
<div id="dvButtonContainer" runat="server" ... >
Another option is to use a Panel, as it outputs a div anyway:
<asp:Panel ID="dvButtonContainer" runat="server" ... >
And in the code behind:
Button button = new Button();
dvButtonContainer.Controls.Add(button);
EDIT: Since DIV is not accessible, here is a workaround:
Button Button1 = new Button();
Page.ClientScript.RegisterStartupScript(this.GetType(), "MyScript", String.Format("document.getElementById(\"div1\").appendChild({0});", Button1.UniqueID), true);
