In my project there is a print button . after clicking that button I want to open a popup but it's not loading

ASP.NET

<table class="inputForm">
<tfoot>
	<tr>
		<td align="right">
		    <asp:Button ID="btnPrint" OnClick="btnPrint_Click" Text="Printuiuiuiui" CssClass="button" runat="server" Visible="true" />
		</td>
	</tr>
</tfoot>
</table>

In .cs file

C#

Page.ClientScript.RegisterStartupScript(typeof(Page), "s1", "openViewer('" + (int)ABCDEF.enReportName.PortfolioPrint + "');");

openViewer is a function that shows popup

JavaScript

function openViewer(reportName) {

  sPath = "/ADDCD/Popups/ifggfjfj.aspx?Viewer.aspx?ReportName=" + reportName;
   
  if (navigator.userAgent.indexOf("Chrome") != -1) {

    return window.open(sPath, self, "dialogHeight: 374px; dialogWidth: 430px; status: no; resizable: no; center: yes;");
  }
  else if (navigator.userAgent.indexOf("Firefox") != -1) {

    return window.open(sPath, self, "dialogHeight: 374px; dialogWidth: 430px; status: no; resizable: no; center: yes;");
  }
  else if ((navigator.userAgent.indexOf("MSIE") != -1) || (!!document.documentMode == true)) { //IF IE > 10
           
    return window.showModalDialog(sPath, self, "dialogHeight: 374px; dialogWidth: 430px; status: no; resizable: no; center: yes;");

  }
}

I tried with Page.ClientScript.RegisterStartupScriptBlock but not working . Anybody have any idea why it's not working?

What I have tried:

I tried with this

C#

Page.ClientScript.RegisterStartupScript(typeof(Page), "openViewer", 
    "openViewer(" + (int)ABCDEF.enReportName.PortfolioPrint + ");", true);

Pretty much every browser these days has an integrated popup blocker. This will prevent Javascript from opening new windows unless it's in response to a user action like clicking on a button.

Your code is trying to open a popup window as soon as the page loads. That will be blocked by the popup blocker. And no, there is no way around that, short of asking your users to disable their popup blockers. Any workaround would be a security vulnerability in the browser, which would be patched PDQ.

Instead, you need to avoid a postback to the server, and open your popup window as soon as the user clicks on the button. How easy that is to do will depend on what else you're doing when the user clicks the button.
