Hello Newgene,

You can attach each RadFilter's ItemCommand event separately and have an if-statement which checks the command name. There are command names for adding and removing expressions:

RadFilter.AddExpressionCommandName
RadFilter.RemoveExpressionCommandName
RadFilter.RemoveGroupCommandName

This way you can execute control-specific logic on the server-side.

Hello,

You cannot check this directly in PreRender, but you could use a global variable, assign its value in ItemCommand and check it on PreRender:

string filterId = "";
protected void RadFilter1_ItemCommand(object sender, RadFilterCommandEventArgs e)
{
    if (e.CommandName == RadFilter.AddExpressionCommandName || e.CommandName == RadFilter.RemoveExpressionCommandName)
    {
        filterId = (sender as RadFilter).ID;
    }
}

protected void RadFilter2_ItemCommand(object sender, RadFilterCommandEventArgs e)
{
    if (e.CommandName == RadFilter.AddExpressionCommandName || e.CommandName == RadFilter.RemoveExpressionCommandName)
    {
        filterId = (sender as RadFilter).ID;
    }
}

protected void Page_PreRender(object sender, EventArgs e)
{
    switch (filterId)
    {
        case "RadFilter1": //.......
            break;
        case "RadFilter2": //......
            break;
        default: //......
            break;
    }
}
