I need to know how to get to the selected value of the filter menu. For example if the user selects "Contains" from the menu, I need to know where to get to the value "Contains".

When I try to get it from column.CurrentFilterFunction, I get an empty string. I was assuming that the CurrentFilterFunction property was what I was looking for, but I guess not.

Is there a way to get this value programmatically?

Thanks,
Eric

Hello Eric,

Try accessing the filter menu in ItemCommand event as shown below.
C#:
protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)
{
 if (e.CommandName == RadGrid.FilterCommandName)
 {
   Pair filterPair = (Pair)e.CommandArgument;
   string value = filterPair.First.ToString();
 }
}

Thanks,
Shinu.

Thank you for your reply, Shinu. I should have mentioned that I had already explored that, but during that event, the filters come through one at a time, which does not work for our needs.

I am trying to loop through the columns and extract it that way to aggregate the filters and associated values, to build a custom where clause for a stored procedure. I'm trying to avoid working with the FilterExpression manually.

Any idea how to best attack this situation - my first time with the RadGrid.

Thanks,
Eric

Hi Eric,

You could achieve your scenario by subscribing to RadGrid PreRender event and access the MasterTableView FilterExpression there and implementing your logic. You could take a look at the help articles below for more information on the topic.
