Execute JavaScript from server side

[Peter]

I have a HoverMenuExtender which contains an asplaceHolder, this place
holder has a User Control and this control contrains a Button.

The problem I am having is after the button fires the click event I want to
do a server side function and then refresh the Page where the PlaceHolder
risides.
I have no problem doing the server side function, but the following 'alert'
never shows up after the server side funtion.

I am using the alert function instead of
'__doPostBack(document.getElementById('upRunningJobs'), "test");' just for
testing as simplicity.

ScriptManager.RegisterStartupScript(this, GetType(), "Refresh",
"alert('test');", false);


Here's my button click event:

protected void butCancel_Click(object sender, EventArgs e)
{
RunningJobsController rjc = new RunningJobsController();
rjc.CancelJob(this.RReport.InstanceID);

//
// the alert from the following line never shows up
//
ScriptManager.RegisterStartupScript(this, GetType(), "Refresh",
"alert('test');", false);

}


Thank You.

No, it does not matter if it's true or false

Does it work if you change the final argument from false to true...?

Hi Peter,

I think it should work if you set the last parameter to true. It looks very
strange. Could you send me a simple demo that can reproduce this problem?
I'll troubleshoot on my side to see what the problem is.

If you do a View Source, do you see the JavaScript alert...?

No I do not

FYI: This is a DotNetNuke application.

Hi Peter,

Thanks for your code. It's a page life cycle issue. You're dynamically
creating controls in the ItemDataBound event handler so the click event of
the button will not fire on postback. To work it around please try
following steps:

1. Comment the following lines in the lstContent_ItemDataBound event
handler in the ViewRunningJobs.ascx.cs:
PopUpData pud
=(PopUpData)Page.LoadControl("~/DesktopModules/RunningJobs/PopUpData.ascx");
pud.RReport = (RunningReport)e.Item.DataItem;
phParameters.Controls.Add(pud);
phParameters.Visible = true;

2. Replace the DataList in ViewRunningJobs.ascx with following one:
<aspataList ID="lstContent" DataKeyField="ItemID" runat="server"
CellPadding="4"
OnItemDataBound="lstContent_ItemDataBound">
<ItemTemplate>
<table cellpadding="4" width="100%">
<tr>
<td valign="top" width="100%" align="left">
<asp:Image ID="imgJob" runat="server"
ImageUrl="" Height="36px" Width="42px" />
<asp:HyperLink ID="HyperLink1" NavigateUrl='<%#
EditUrl("ItemID",((int)DataBinder.Eval(Container.DataItem,"ItemID")).ToStrin
g()) %>'
Visible="<%# IsEditable %>" runat="server">
<asp:Image ID="Image1" runat="server"
ImageUrl="~/images/edit.gif" AlternateText="Edit"
Visible="<%# IsEditable%>"
resourcekey="Edit" />
</asp:HyperLink>
<asp:Label ID="lblContent" Font-Size="12pt"
ForeColor="Blue" runat="server" />
--> Start Time '<%#
DataBinder.Eval(Container.DataItem,"StartTime") %>' <span id="InstanceID"
style="display: none">Report ID '<%#
DataBinder.Eval(Container.DataItem, "InstanceID")%>'
</span>
<div>
<cc1:HoverMenuExtender
ID="HoverMenuExtender1" runat="server" TargetControlID="imgJob"
PopupControlID="pnlReportInfo"
PopupPosition="Right" PopDelay="25" OffsetY="-240" OffsetX="-30">
</cc1:HoverMenuExtender>
<aspanel ID="pnlReportInfo" runat="server"
CssClass="balloonstyle">
<br />
<br />
<asplaceHolder ID="phParameters"
runat="server">
<uc1opUpData runat="server"
ID="PopUpData1" Visible="true" /></asplaceHolder>
<DBWCynamicControlsPlaceholder
ID="phParameters1" runat="server">
</DBWCynamicControlsPlaceholder>
</aspanel>
</div>
</td>
</tr>
</table>
</ItemTemplate>
</aspataList>

In this way we add the PopUpData control in aspx directly instead of
dynamically creating it in the code behind. The control will then be
populated on an earlier stage of the page life cycle that can make sure the
event will fire on the postback.
Please let me know if it works.

Thank You for your help

But the changes did not help, still JavaScript does not execut from the
button_click event in the User Control.
