             runat="server"><%#Eval("AdhocBurstingReportName")%>

You use master pages thus your repeater reside in Content Place Holder. What you need to do is find control of the Content Place Holder first before you find the repeater.

Example:

Control placeHolder = PreviousPage.Controls[0].FindControl("ContentPlaceHolder1");
TextBox SourceTextBox = (TextBox)placeHolder.FindControl("TextBox1");
if (SourceTextBox != null)
{
    Label1.Text = SourceTextBox.Text;
}

I assume in your case, instead of creating TextBox you should create repeater object and use FindControl again to find the link.
