Can anybody tell me how to popup new window in SelectIndexChanged function?

[Simon Durant]

Hi guys,

I got a problem regarding user chooses a specified option in combobox, poping up a new window for user.

the aspx code just put a telerik radcombobox on the web page and set SelectIndexChanged event
backend code are:

 protected void ddlClient1_SelectedIndexChanged(object sender, EventArgs e)
      {
         if (ddlClient1.SelectedValue.Equals("-1"))
            {
            string script = "alert('aabb')";

            Page.ClientScript.RegisterClientScriptBlock(this.GetType(), ((Telerik.Web.UI.RadComboBox)sender).ClientID, script, true);
         }
      }

but it doesn't work.

Thanks

Alex

Hello Simon,

You can open the window from code behind as shown below.

CS:

    protected void RadComboBox5_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
    {
        if (RadComboBox5.SelectedValue.Equals("-1"))
        {
            RadWindow newWindow = new RadWindow();
            newWindow.NavigateUrl = "http://www.google.com";
            newWindow.VisibleOnPageLoad = true; // Set the VisibleOnPageLoad to true
            this.form1.Controls.Add(newWindow);
        }
    }
