Empty wingrid shows column headers
posted

Using 8.2.20082.2187, I have a wingrid bound to a generic IList of a custom object via its Datasource property.

 

                gridCipherVariation.DataSource = null;

                gridCipherVariation.DataSource = someInstanceOfIListCollection

When the grid is first displayed, the collection is empty, has a count of 0. The grid displays "drag a column here to group by that column" and below that the 3 column headers.

I set the DisplayLayout.GroupByBox.Hidden to true, but the "drag a column..." remained.

How can I get to grid to display nothing when its datasource is empty?

Thanks, Lars

    Hi Lars,

    What exactly do you want to remove?

    Setting GroupByBox to hidden should remove the GroupByBox. If that's not working, then something is wrong. Perhaps you are loading a layout into the grid after setting the Hidden property, so it's getting set back to true (or default) after you set it. 

    If you want to remove the column header, then you either need to set the grid's DataSource to null, or else use a CreationFilter. I posted some sample code demonstrating this here in this thread:
