c# - Opening a URL in a new tab

Question

I have an url like

Response.Redirect("~/webpages/frmCrystalReportViewer.aspx?VoucherNo=" + txtVoucherNo.Text + "&VoucherDate=" + txtVoucherDate.Text + " &strUserCode=" + strUserCode.ToString() + "&strCompanyCode=" + strCompanyCode.ToString() + "&formName=frmPaymentVoucher");

I want to open this url in new tab of browser. I tried below code...

string pageurl = "~/webpages/frmCrystalReportViewer.aspx?VoucherNo=" + txtVoucherNo.Text + "&VoucherDate=" + txtVoucherDate.Text + " &strUserCode=" + strUserCode.ToString() + "&strCompanyCode=" + strCompanyCode.ToString() + "&formName=frmPaymentVoucher";
Response.Write("<script>");
Response.Write("window.open('" + pageurl + "','_blank')");
Response.Write("</script>");

also i tried below

string pageurl = "~/webpages/frmCrystalReportViewer.aspx?VoucherNo=" + txtVoucherNo.Text + "&VoucherDate=" + txtVoucherDate.Text + " &strUserCode=" + strUserCode.ToString() + "&strCompanyCode=" + strCompanyCode.ToString() + "&formName=frmPaymentVoucher";
 ScriptManager.RegisterStartupScript(Page, Page.GetType(), "popup", "window.open('" + pageurl + "','_blank')", true);

also i tried

<asp:Button ID="btnPrint" Text="Print" runat="server" OnClick="btnPrint_Click" OnClientClick="aspnetForm.target ='_blank';"/>

but all are not working. Please tell me any another solution. Thanks in advance.

Answer 1

You are using URL with ~ and it won't recognize by javascript. You should process url with ~ by using ResolveUrl method which

converts a URL into one that is usable on the requesting client(c)msdn

In your case:

Response.Write(String.Format("window.open('{0}','_blank')", ResolveUrl(pageurl)));
