Prometheus Panelbar client-side/server-side

[Waleed Seada]

Dear all,

I use Panelbar on one of my user-controls which I placed in a pane of radsplitter on a master-page.

This panelbar is Ajaxified with other panel on the master-page.

I have a method (loadusercontrol) on the master-page that is called by this panelbar via (OnItemClicked) server side method, everything was fine until I notice that the method is called whenever I clicked on panelbar root-item or item, and I wanted to change this that the method is called on clicking the items only.

So, I think of doing this via client-side script, so I created a javascript method OnClientItemClicking="panelclicked" to handle this situation as follows:

<telerik:RadCodeBlock ID="CB1" runat="server">
    <script type="text/jscript" language="javascript">
        function panelclicked(sender, e)
        {
            var panelBar = $find("<%= navpanelBar.ClientID %>");
            var item = panelBar.findItemByText(e.get_item().get_text());
            if (item)
            {
                if item.get_text() == "AVT data"
                {
                    "<% MasterP.LoadUserControl("MainDataEntry.ascx", MasterP.MainPanel); %>"
                }
                else
                {
                }
            }
        }
    </script>
</telerik:RadCodeBlock>

when I run the application I got this error:
"Script controls may not be registered after PreRender"

This error appear on the loadusercontrol method of the master-page:

public void LoadUserControl(string controlName, Control parent)
    {
        parent.Controls.Clear();
        UserControl MyControl = (UserControl)LoadControl(controlName);
        string userControlID = controlName.Split('.')[0];
        MyControl.ID = userControlID.Replace("/", "").Replace("~", "");
        parent.Controls.Add(MyControl);
        CurrentControl = controlName;
    }

at that line : parent.Controls.Add(MyControl); 

any advice in this situation ...

Thanks and best regards
Waleed

Hi Waleed ,

I suggest you just set PostBack property of the root items to False. Then OnItemClicked server side event will fire only for the items and you can use your first approach.
