this.Page.ClientScript.RegisterStartupScript not working: C#, .NET, ClientScript, RegisterStartupScript

Works perfectly for me on a new blank page in both FF and IE.

You have some other code that is getting in the way, or your popup blocker is on (something like that).

No I debugged and stepped through all my code and everything was fine. Even when I turn off the IE pop-up blocker it still doesn't work.

The register Startup script call is in a button click event. Here is some more code:

from ASPX page:
<tr>
              <td valign="top">
                   <asp:UpdatePanel ID="updPurchases" runat="server">
                   <ContentTemplate>
                   <asp:PlaceHolder ID="phPurchases" runat="server" />
                   </ContentTemplate>
                   </asp:UpdatePanel>
</td>
</tr>

from PageLoad Method:
btnLink.Click += new EventHandler(btnLink_Click);

from btnLink_Click Method:
//Open up a new window for the pre-recorded seminar
string scriptText = "window.open('" + myURL + "','_blank','height=700,width=800,status=no,toolbar=no,menubar=no,location=no,resizable=yes,titlebar=no');";
this.Page.ClientScript.RegisterStartupScript(this.Page.GetType(), "openSeminar", scriptText, true);

this is for the PageLoad Method as well after I add the click event handler
cell.Controls.Add(btnLink);

and the cell is inserted into a table that is in the placeholder phPurchases

OK, I understand, but you are missing something...

If you make a blank page in VS, copy that code into the page_load, put something in for the myURL variable and run the code it gives a popup window.

It renders on the page thusly:
<script type="text/javascript">
//<![CDATA[
window.open('Default.aspx','_blank','height=700,width=800,status=no,toolbar=no,menubar=no,location=no,resizable=yes,titlebar=no');//]]>
</script>

I'm not trying to make your life difficult. I'm just pointing out that the code given works. That is all I have to work with and so it's all I can report to you. If your code is not too complex and dependent on resources I can't duplicate then post it and Ill take a look.

Otherwise, start turning things off until you find your culprit, something (likely unexpected or unusual) is causing this to fail.

Sorry I didn't see your new post, we were typing at the same time.

Could it be the updatepanel and AJAX messing it up?

by: ddayx10Posted on 2009-06-23 at 15:05:00ID: 24696756

OK so... the plot thickens!

You can register the script block on its own from the page load, no prob. You cannot register it from an async postback of an update panel though. Well you can but the postback ignores it. Using the update panel it is not paying any attention to loading the entire page back, it disregards running the entire page, it only re-runs (if you will) the contents of the updatepanel.

I put together a sample that demonstrates how you can get around this behavior and still be nimble in with your potential needs.

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="sm" runat="server" />
	<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
		<ContentTemplate>
			<asp:PlaceHolder ID="phPurchases" runat="server" />
		</ContentTemplate>
	</asp:UpdatePanel>
    
    
    </form>
	
</body>
</html>
 
 
 
public partial class Default14 : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        registerME(); //causes to open new page on load (not needed)
 
        Button btnLink = new Button();
        btnLink.Text = "ClickMe";
        btnLink.OnClientClick = "fireMe();";
        btnLink.Click += new EventHandler(OnEvent);
        phPurchases.Controls.Add(btnLink);
    }
 
    public void OnEvent(object sender, EventArgs e)
    {
        //registerME(); //no longer needed here
        //can still do something else if needed
        //otherwise return false from javascript and wont even get a postback :)
    }
 
 
    public void registerME()
    {
        //Open up a new window for the pre-recorded seminar
        string myURL = "Default.aspx";
        string scriptText = "function fireMe(){window.open('" + myURL + "','_blank','height=700,width=800,status=no,toolbar=no,menubar=no,location=no,resizable=yes,titlebar=no');}fireMe();";
        this.Page.ClientScript.RegisterStartupScript(this.Page.GetType(), "openSeminar", scriptText, true);
    }
 
}

Select all Open in new window

by: quanmacPosted on 2009-06-23 at 15:24:19ID: 24696904

So let's say I have a list of buttons that would open up a different url for each one, I just have to make the function with a parameter and on OnClientClick, I can specify it there right?

I will give this a try, I'm off work in 5 mins, so I won't be able to get to it today. I make the changes in the morning and test it out.

Thanks

Yes that sounds plausible.
