I have a linkbutton in my tab template but when I click on it no postback event is fired.  Is there anything special I need to do to enable this?

Hi Scott Rakestraw,

I've attached a sample page which demonstrates the requested capability.

RadTabStrip currently consumes the click event of the link button due to DOM event bubbling. You need a JavaScript routine to prevent that:

    <script type="text/javascript"
        function stopPropagation(e) 
        { 
            e.cancelBubble = true
            if (e.stopPropagation) 
                e.stopPropagation();     
        } 
    </script> 
    <telerik:RadTabStrip runat="server" ID="RadTabStrip1"
        <TabTemplate> 
            <asp:LinkButton runat="server" ID="LinkButton1" Text='<%# DataBinder.Eval(Container, "Text") %>'  
            OnClick="LinkButton1_OnClick"
OnClientClick
="stopPropagation(event)"></asp:LinkButton> 
        </TabTemplate> 
        <Tabs> 
            <telerik:RadTab Text="Tab1"></telerik:RadTab> 
            <telerik:RadTab Text="Tab2"></telerik:RadTab> 
            <telerik:RadTab Text="Tab3"></telerik:RadTab> 
        </Tabs> 
    </telerik:RadTabStrip>

Hello,

ok the javascript works nice. But I like to take it up a level. Is it possible to ajaxify this linkbutton with a proxymanager in code behind??

already tried it out but without succes.

This is really keeping us occupied.

thanks in advance

Hello Geert,

Have you tried creating the AjaxSettings from codebehind? You need to pass a reference to the specific linkbutton. You can get one using the FindControl method of the RadTab object.

Hello,

Yes I do, like this in the PageLoad:

if

(RadTabStrip1.SelectedIndex == 0)
{
ImageButton btnRefresh = (ImageButton)RadTabStrip1.Tabs[0].FindControl("btnRefresh");
if (btnRefresh != null)
{
M
etisCollectionManager.AjaxSettings.AddAjaxSetting(btnRefresh, tvDossiers);
MetisCollectionManager.AjaxSettings.AddAjaxSetting(btnRefresh,
pnlCollectionEmployee_Updatable);
}
}

<

telerik:RadTab>
<TabTemplate>
<asp:Label ID="lnkSelection" runat="server" Text="Selectieboom"></asp:Label>
<asp:ImageButton runat="server" onmouseover="style.cursor='pointer'" AlternateText="refresh collection"Width="10px" OnClientClick="stopPropagation(event)" Height="10px" ToolTip="refresh collection" ID="btnRefresh" OnClick="RefreshTreeViewAndCollection" ImageUrl="~/Images/refresh.jpg" />
</TabTemplate>
</telerik:RadTab>

Any IDs?

Hello,

We also discovered a short error before starting the postback and it goes like this:

this._postBackSettings.async is null or not an object

maybe this can help??

Hi Geert,

Please try removing the OnClientClick attribute of the imagebutton and pasting this javascript below your radtabstrip declaration:

    <script type="text/javascript">
    var click = Telerik.Web.UI.RadTabStrip.prototype._click;
    Telerik.Web.UI.RadTabStrip.prototype._click = function (e)
    {
        if (e.target.tagName.toLowerCase() =="input")
            return;
           
        click.apply(this, arguments);
    }
    </script>

Sincerely yours,

Hello,

this solutions seems to work allthough it looks like serious kind-a-hacking. We will try to solve it out and try to understand.

For now thanks a lot.

PS I'm trying to open a radwindow from an imagebutton next to this one in the tab which when closed will also update several stuff,...
I'll first try it myself but maybe it's good to mentally prepare yourself for new questions. :) hèhè

thanks from the SOFIM-team (Belgium)
