Conditional display: ItemDataBound vs PreRender

I'm new to the grid so please bear with me. I've got a GridTemplateColumn which I'm using to display an image.

<telerik:GridTemplateColumn HeaderText="Address" UniqueName="Address" ItemStyle-Width="20">

<ItemTemplate>

<a href='<%# Eval("Address") %>' title='<%# Eval("Address") %>'><img src="images/go.gif" border="0" width="33"></a>

</ItemTemplate>

</telerik:GridTemplateColumn >

This shouldn't be visible if the data is empty, so in the ItemDataBound method, I did

Dim item As GridDataItem = CType(e.Item, GridDataItem)

If condition Then

item("Address").Controls(0).Visible = False

End If

And this worked just fine under FireFox. But with IE8, it doesn't. Instead, I had to move this to the PreRender method where I had to iterate through the items with the same logic to get it to work. And this approach also works fine under FireFox too, so that's good.

But since I'm new to the grid, I'm wondering, is there a "correct" or recommended place to do this kind of logic? I initially went with the ItemDataBound because that's where similar approaches that I'd found (e.g. here ) had done it. But that obviously didn't work for me with IE8.

GridCheckBoxColumn is too grayed-out in regular mode (in which it is disabled)

Hi,

I created a RadGrid control on the page and it has one GridCheckBoxColumn bind to a boolean field value in the database. I found that it looks too grayed-out in regular mode (in which the checkbox is disabled). Is there anyway to make it look more readable like in Edit Mode (in which the checkbbox is enabled).

Thanks

Lamk.

How do you format Groupfooter?

Adding the groupfooter and calculating a total for a column was pretty easy, but how can I format the output so that it shows something besides "Sum: 9999"?

Radmenu's submenus Z-index specify by programmatic assigning

I have a radmenu that I generate by examing sharepoint document library folders and building out a submenu structure based on the folder.
When I put many of the control on the page, the root menu from other controls shows up over the sub menu of the control.
Does anyone know how to prevent it, by altering programatically assigning the style for the z index to the sub menus?
See the attached file for a better understanding of the problem. The text was sanitized for public consumption.

Edit:
Additional Information: When rolling over the menu and the subitems menu shows it does properly cover the other menus and they do not show through. However when rolling over it a 2nd time it definitely shows through, as though its z index is larger.

These controls are each in their own webparts, does that matter? Maybe they're inheriting z-index?

Edit: more info: the effect only occurs in IE, didn't occur in chrome or mozilla firefox

My ascx: (customItem is the submenu), these classes are applied programmatically in code

<style type="text/css">

.CustomItem

{

z-index:99999;

}

.rootItem

{

text-align:center !important;

text-decoration:none !important;

z-index:-1;

}

.CustomItem:hover

{

text-decoration:none !important;

}

</style>

<div id="section" runat="server" >

<telerik:RadMenu ID="FolderMenu" runat="server">

</telerik:RadMenu
