Question

I am trying get Javascript popup calendar control to work which doesnt work. I am getting

an error “Microsoft JScript runtime error: ‘window.opener.document.forms(…).control’ is null or not an object”. Here is my event,

protected void Change_Date(System.Object sender, System.EventArgs e)
{
    string strScript = "<script>window.opener.document.forms(0)." + control.ClientID + ".value = '";
        strScript += calDate.SelectedDate.ToString("MM/dd/yyyy");
        strScript += "';self.close()";
        strScript += "</" + "script>";

        ClientScript.RegisterClientScriptBlock(this.GetType(), "Startup", strScript);
}

It displays the calendar fine but when I click on the date, I am getting the error and the date is inserted into the textbox.

Answer 1

wrong brackets:

.document.forms(0)

should be

.document.forms[0]
