Overlapping tabs problem

dear all,

I am trying to add in pictures for the tabs, and want them to overlap (like the attached picture).

I use margin on all of them, so that they will squeeze together, and then use z-index to arrange them.

but the problem is the z-index only affects the first tab, the other 3 tabs does not arrange according to the z-index

I use C# (Telerik Version=2010.3.1317.35) and my code looks like :

AddTab("Account Info", true, "10");
AddTab("Enter Info", true, "8");
AddTab("Confirm Info", true, "2");
AddTab("Submit", true, "1");

private void AddTab(string tabName, bool enabled, string zIndex)
{
RadTab tab = new RadTab(tabName);

tab.Style.Add("margin-right", "-28px");
tab.Style.Add("position", "relative");
tab.Style.Add("z-index", zIndex);
tab.Enabled = enabled;
RadTabStrip1.Tabs.Add(tab);

difficult to override RenderControl() methord with Telerik

I need to dynamically add some controlls to a web user control.

I'm putting all the controlls to a Table control and adding to the page as follows at the RenderControl event.

Public Overrides Sub RenderControl(ByVal writer As System.Web.UI.HtmlTextWriter)

Dim panel As New Panel

Dim outerTable As New Table

outerTable = generateDynamicControls()

panel.Controls.Add(outerTable)

panel.RenderControl(writer)

MyBase.RenderControl(writer)

End Sub

When I adding simple ASP controls to this outer table, it is working fine.
But when I add Telerik Controls gives following error when it execute "panel.RenderControl(writer)" code.
Error:
Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

I'm using a Master page also.

Can u help me?

Custom Validator not invoked in RadGrid

Hi everybody,

Since RadNumericTextBoxes do not provide a build-in feature to have it as required field, we implemented a custom validator that checks for a missing value. This validator works well, if the NumericTextBox is not within a RadGrid. If we use the custom validator within a EditTemplate, it is not invoked. When we use a asp:RequiredFieldValidor instead, the validation is processed. Why is a custom validor not invoked when we click "Insert" or "Update" while a RequiredFieldValidator works correctly?

Thanks in advance
Marco

<EditFormSettings EditFormType="Template">

<EditColumn FilterControlAltText="Filter EditCommandColumn column" />

<FormTemplate>

<table cellspacing="2" cellpadding="1" border="0">

<tr>

<td>

<telerik:RadNumericTextBox ID="Amount" runat="server" DbValue='<%# Bind("Amount") %>' Width="80px" />

<asp:RequiredFieldValidator ControlToValidate="Amount" ErrorMessage="*" runat="server" Text="*" />

<asp:CustomValidator ID="Amount_Required" ClientValidationFunction="CheckNumberRequired"

ControlToValidate="Amount" runat="server" ValidateEmptyText="true" />

</td>

</tr>
