RadGrid ToolTip Shows   After Postback

[Doug]

I have a RadGrid control in which I want to display a ToolTip for certain columns which contain information from the same data row in the data table.  I'm getting the results I expect on the first load of the RadGrid.  However, if I push a button which does a postback and databinds the RadGrid to the new SQL, I only get $nbsp; as the tooltip.  I've searched and can not find the answer.  Please help.

ASPX  (It does become visible in the button push).

<telerik:RadGrid ID="radgrid1" runat="server" Visible="False" MasterTableView-EnableNoRecordsTemplate="true" DataSourceID=""
    AllowPaging="True" PageSize="20" OnItemDataBound="radgrid1_ItemDataBound">
    <MasterTableView></MasterTableView>
</telerik:RadGrid>

This is the code within radgrid1_ItemDataBound which does provide the correct results the first rendering of the RadGrid.

If (TypeOf e.Item Is GridDataItem) Then
    Dim dataItem As GridDataItem = CType(e.Item, GridDataItem)
    dataItem("SSN4").ToolTip = dataItem("SSN").Text
    dataItem("Client").ToolTip = dataItem("Description").Text
    dataItem("Status").ToolTip = "Change date: " & dataItem("StatusChangeDate").Text
End If

Hi Jack,

I tried a similar scenario and the code works fine at my end. Make sure that you are binding the RadGrid using Advanced Data-binding (using NeedDataSource event). Please provide your full code snippet if this doesn't help.

Thanks,

Thanks for the reply.  I tried that and it didn't seem to make a difference.  I believe the issue I was having had to do with hiding the three columns during the grid prerender from the data source which were visible in the tooltip.  I turned off AutoGenerateColumns and added each column to the MasterTableView and then disabled ViewStateMode.  Now it works as expected.
