radFilter change Expression Field Name

[rik butcher]

this is an almost perfect solution except when there are more than one fieldName on the page.i add the 1st one and put in a value in the text field - so far so good.
add the 2nd one & changed the Filter Expression - it changes the expression on the top one and clears the text box. i sort of underStand why it's doing that, but what i don't know is how to tell it which one i'm on.
for instance  say, two Field Editors: Workordernumber & PoNumber.(in that order)
i create one: workordernumber & put in a value.
then create another & when i change from workordernumber to PoNumber on the 2nd one, it changes the 1st one at the top and blanks out the Value previously put in. it's performing the RecreateControl on the wrong one.....or rather, not the one i intended. how could i limit the "ChangeExpression" to the one that's being change.
thanks again for any help

Hello Rik,

Please try using the following code in order to implement the desired functionality:

protected void RadFilter1_ItemCommand(object sender, RadFilterCommandEventArgs e)
{
    if (e.CommandName == RadFilter.AddExpressionCommandName)
    {
        e.Canceled = true;
        RadFilterStartsWithFilterExpression item = new RadFilterStartsWithFilterExpression("WORKORDERNUMBER");
        (e.ExpressionItem as RadFilterGroupExpressionItem).Expression.AddExpression(item);
        RadFilter1.RecreateControl();
    }
    else if (e.CommandName == RadFilter.ChangeExpressionFieldNameCommandName)
    {
        string myCmdArg = e.CommandArgument.ToString();
        if (myCmdArg != "WOTYPENAME" & myCmdArg != "STATUS_MESSAGE" & myCmdArg != "MATERIALTYPE" & myCmdArg != "CREATEDDATE")
        {
            e.Canceled = true;
            RadFilterStartsWithFilterExpression item = new RadFilterStartsWithFilterExpression(e.CommandArgument.ToString());
            //replace the current item with the new item that has the default filter set to StartsWith
            int i = e.ExpressionItem.ItemIndex;
            e.ExpressionItem.OwnerGroup.Expression.Expressions.RemoveAt(i);
            e.ExpressionItem.OwnerGroup.Expression.Expressions.Insert(i, item);
            RadFilter1.RecreateControl();
        }
    }
}

I hope it helps.
