Hi,
I've got a problem using the GridCheckBoxColumn. I'm using v.2009.2.826.35 with RadGrid and a LinqDataSource control. It picks up the boolean fields and chooses to use a GridCheckBoxColumn which is fine. The problem is that I can't get the checkbox filter to autoPostBack even though AutoPostBackOnFilter is set. I basically want to eliminate the need for the filter icon since the checkbox should be enough (then I just to set the CurrentFilterFunction to "EqualTo"), since it's a boolean field and there's already constraints on the DB to not allow nulls. There's no need for the filter menu icon.
AutoPostBack on all the other filters work fine. From the resulting HTML, it seems that no "onclick" event is being rendered as is done when you use a regular ASP:CheckBox and set AutoPostBack=true. All the the other filters with AutoPostBackOnFilter set (for other GridBoundColumns resulting in different input types such as textbox types) are rendered with an "onchange" client side event.
Anyway, here's the code for 2 such columns:
I've tried this many different ways with the properties set numerous ways and can never get the filter column for the check box to post back on check change. the user still haa to go to the filter icon and select "EqualTo" from the filter menu or get it to postback some other way (e.g. by using another filter with AutoPostBackOnFilter set).
Is this a bug or am I just missing something simple?
Is the only alternative to use FilterTemplate and/or GridTemplateColumn for every column I want to do this?
Thanks,
Brad

| DataField="Error" HeaderText="Error?" SortExpression="Error" UniqueName="Error" | |
| CurrentFilterValue="True" ReadOnly="True" ShowFilterIcon="false"> | |
| </telerik:GridCheckBoxColumn> | |
| <telerik:GridCheckBoxColumn AutoPostBackOnFilter="True" DataField="Truncated" DataType="System.Boolean" | |
| HeaderText="Trunc?" SortExpression="Truncated" UniqueName="Truncated" ReadOnly="True"> | |
| </telerik:GridCheckBoxColumn> |
