how to get link to open new tab in browser? - asp.net

Question

I have a save button that saves all the information the user enters from a form into the database. Once all that is done, I want a new tab to automatically open.
So the code checks if the save is successful then I want the new tab to open.
if (NewQuoteID != -1)
{
Response.Redirect("Printouts/DSVQuotation.aspx?QuoteID=" + NewQuoteID.ToString(), false);
}
Code for the save button:
<asp:LinkButton runat="server" ID="btnSave" CssClass="btnSaveLarge loading" OnClientClick="return CheckNoOfDetails()" ToolTip="Save Quote" OnClick="btnSave_Click" Text="Save" />
This code opens the link on the same tab. How do I get the link to open on a new tab in the browser? I see a lot of examples are setting the OnClientClick to something like this: OnClientClick="aspnetForm.target ='_blank';"
But I am already calling a method in the OnClientClick

Answer 1

Try this:
OnClientClick="window.open('New.aspx')"

Answer 3

if you want open tab after server side save operation is success..
client side :
<script type="text/javascript">
var openNewTab = function (url) {
window.open(url);
}
</script>
server side
if (NewQuoteID != -1)
{
var url = "Printouts/DSVQuotation.aspx?QuoteID=" + NewQuoteID.ToString();
ClientScript.RegisterStartupScript(this.GetType(), "openmypage", string.Format("openNewTab('{0}');", url), true);
}
