Radconfirm called by "automated" script

[Gianluca]

Hi,

I'm upgrading my older version of telerik radwindow with the newest one.

I need to show radconfirm by an action on a radgrid, after postback, so I manage a label inside a hidden placeholder (called "labAlert"), and on postback i assign to "labAlert.Text" a script that calls radconfirm, and i set visible the placeholder

this is on ascx.cs:

    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "ActionName")
        {
            String ScriptJs = "<script language=JavaScript>";
            ScriptJs += "{";
            ScriptJs += "ShowConfirm('ConfirmText')";
            ScriptJs += "}";
            ScriptJs += "</SCRIPT>";
            labALERT.Text = ScriptJs;
            PlaceHolder1.Visible = true;
            e.Canceled = true;
        }

and this is on .ascx

<script type="text/javascript">
    function ShowConfirm(text)
    {
        radconfirm(text, confirmCallBackFn, 200, 100, '', ' ');
        return false;
    }
    function confirmCallBackFn(Conferma)
    {
        if (Conferma)
        {
            [...javascrip actions if OK ...]
        }
        else
        {
           [...javascrip actions if CANCEL...]
        }
    }
    </script>

whith old version of radwindow it works fine, but with new version i get a javascript error on browser when radconfirm is called...

Where is the difference???

Thanks in advance

Hi Gianluca,

Your site is an AJAXEnabledWebSite and the page lifecycle is the lifecycle of an ajaxified page. The RadControls (ASP.NET Ajax version) as all ajax objects are rendered last on the page. Therefore you need to ensure that before the function's execution the RadWindowManager control is rendered on the page. To do this you should add a load handler and execute your function there as shown below. Give a try with this code snippet and see whether its working fine for you.

CS:

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
    if (e.CommandName == "ActionName")
    {
        labALERT.Text = "<script type='text/javascript'> Sys.Application.add_load(function(){ShowConfirm('ConfirmText');})</script>";
        PlaceHolder1.Visible = true;
        e.Canceled = true;
    }
}

Thanks,
Shinu.
