This is strange. I have an application with a number of GridViews in separate user controls.
The code underneath each one is very similar but for some reason on GridView1 when the user clicks on the funnel icon the filter drop down - drops down (opens) but in GridView2 when the funnel is clicked on - nothing happens. The drop down won't 'drop down'. The filter row can be typed in but clicking the icon has no effect whatsoever... and I can't figure out why.
Has anyone else experienced this issue and if so how does one go about fixing this issue?
