Filter on showing results on postback....

[DuntonMCAD]

Hi -

I have a basic radGrid that I have wired up with a dataset using the Telerik AjaxManager and RadScriptManger.
 
I used the basic procedure outlined in the Rad Ajax Courseware. It worked the first time, but the second one I just created in not working.

Here's what is happening:

 

• I enabled filtering on the grid via the SmartTag and PropertyBuilder->General Settings->Allow Filtering By Column.
• I am using RadGrid.ReBind to initailly bind my grid to the data and this is working fine.
• At runtime, the gird shows data and I can apply a filter by any column, but when I set the condition like "contains", the gird just disappreas. 
• However, when I press any button on the form that causes a post back, the Grid then correctly shows the filtered data.

This is only the second grid I have wired up. What might be causing this unwanted behavior?

Any help is appreciated.

PS- I am using v2010.1.209.35
