Question

Clicking on ASP.NET button redirects to correct website but on the same tab, not in a new tab what i need to do. What’s wrong with the code OnClientClick="aspnetForm.target ='_blank';" below? Why it is not enough alone and what else need to be done?

The following ASP.NET code for the button control is:

<asp:Button ID="btnGenerateReport" runat="server" Text="Generate Report" 
OnClick="btnGenerate_Click" OnClientClick="aspnetForm.target ='_blank';" />

If you are looking out for server side code to open a new window on Button Click, then here’s how to do so.

Add the following script to the section of your page

<script language="javascript" type="text/javascript">
    function openNewWin(url) {
        var x = window.open(url, 'mynewwin', 'width=600,height=600,toolbar=1');
        x.focus();
    }
</script>

Then add a Button Control in the following manner

<asp:Button ID="btnOpenPop" runat="server" Text="Open Pop"           
    onclick="btnOpenPop_Click" />

Finally add some code in the code behind file

protected void btnOpenPop_Click(object sender, EventArgs e)
{
    string url = "http://www.dotnetcurry.com";
    ClientScript.RegisterStartupScript(this.GetType(), "OpenWin", "<script>openNewWin('" + url + "')</script>");
}
