Problem with OnTabClick

[Lucas Bailey]

I have a RadTabStrip control.  I create the tabs dynamically by binding a DataTable.  The Datatable has four columns: ID, Name, URL, and ParentID.  When a tab is clicked, it redirects to the page specified by the URL.

I want to add some functionality before the redirect.  When I add an addtabclick property to the RadTabStrip, nothing happens.  There is also no Postback on the page the click occurs on.

 

What am I missing?

Code would be helpful, but I believe what you are missing is ClickSelectedTab="True" in the RadTabStrip declaration.

That didn't work.  So here's my code.

<telerik:RadTabStrip ID="rts_Tabs0" runat="server" DataNavigateUrlField="URL"
        DataTextField="Name" DataValueField="ID" DataFieldID="ID"
    DataFieldParentID="ParentID" CausesValidation="false" Skin="CCI" EnableEmbeddedSkins="false" ontabclick="RadTabStrip1_TabClick" ClickSelectedTab="true"></telerik:RadTabStrip>

And my bind code

protected void BindTabs()
    {
        IList<ProviderCategory> topLevelCategories = CCIPage.ObjectModel.CategoryFactory.GetAllProviderCategories(false, true);
        IList<ProviderCategoryWrapper> topLevelTabs = new List<ProviderCategoryWrapper>();
        RadTab tab;
        int topLevelCategoryCount = 0;

        DataTable tabs = new DataTable();
        tabs.Columns.Add(new DataColumn("ID", typeof(long)));
        tabs.Columns.Add(new DataColumn("Name", typeof(string)));
        tabs.Columns.Add(new DataColumn("ParentID", typeof(long)));
        tabs.Columns.Add(new DataColumn("URL", typeof(string)));



        foreach (ProviderCategory pc in topLevelCategories)
        {
            DataRow dr = tabs.NewRow();

            dr["ID"] = pc.CategoryID;
            dr["Name"] = pc.Category.Label;
            dr["URL"] = "~/Client/Profile/" + pc.Category.StandardName + "Tab.aspx";

            if (pc.Category.ParentCategory != null)
                dr["ParentID"] = pc.Category.ParentCategory.ID;
            else
                dr["ParentID"] = System.DBNull.Value;

            tabs.Rows.Add(dr);

            if (pc.ParentProviderCategory == null)
                topLevelCategoryCount++;
        }

        int breakPoint = 0;
        if(topLevelCategoryCount > 9)
            breakPoint= topLevelCategoryCount / 2;

        rts_Tabs0.DataSource = tabs;
        rts_Tabs0.DataBind();

        //set the tabindex to -1 so they are not a tab stop
        for (var x = 0; x < rts_Tabs0.Tabs.Count(); x++)
        {
            rts_Tabs0.Tabs[x].TabIndex = -1;
        }

        if (breakPoint > 0)
        {
            tab = rts_Tabs0.Tabs[breakPoint - 1];
            tab.IsBreak = true;
        }

        tab = rts_Tabs0.FindTabByUrl(Request.Url.PathAndQuery);
        if (tab != null)
            tab.SelectParents();
    }

Hello,

This is by design. When you set the NavigateUrl property of a tab the TabClick event does not fire for that tab. If you need to first postback then redirect you should avoid setting the NavigateUrl property. You can store it in the Value property or use a custom attribute (to do this you need to subscribe to the TabDataBound event). Then in your TabClick event you can use Response.Redirect to perform the navigation.

I figured it was something like that.  The work-around works like a charm. Thanks
