Solution 1

if you are using window.open then specify windowname as below

for example :

C++

window.open("htp://www.google.com","mycustomwindow")

void lnkViewOrderDocuments_Click(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
if (null != Request.QueryString[CONST_OrderNo])
{
string dmuUrl = OrderHelper.SetDMULinkURLFromConfig(Request.QueryString[CONST_OrderNo].ToString(),
Request.QueryString[CONST_OrderType].ToString());
sb.Append(@"<script language="'javascript'" type='text/javascript'>");
sb.Append(dmuUrl.Trim());
sb.Append(@"</script>");
this.RegisterStartupScript("RegisterSalesTextScript", sb.ToString());
}
}
}

sDocumentMergingUtilityURL = string.Format("javascript:window.open('" + sDocumentMergingUtilityURL + "','Window1');return false;");

Try this Javascript function:

function OpenURL()
        {
            var hdnFlag = document.getElementById('<%= hdn.ClientID %>');
            if(hdnFlag.Value > 0)
            {
                window.location = "http://www.google.co.in";
            }
            else
            {
                hdnFlag.Value = 1;                
                window.open("http://www.google.co.in"); 
                self.focus();
            }
        }

Here "hdn" is a hidden field in the page which should keep track if the button is already clicked or not.

Note: Remember that on page refresh this flag will be reset.

Hope this helps!
