DetailGrid Exception

[User (Old forums)]

#15865 |

I am trying to add a DetailGrid to my grid and I keep getting the following exception when I open the grid:

System.NullReferenceException: Object reference not set to an instance of an object.
at Xceed.Grid.DetailGrid.UpdateDetailGridTemplateBinding(DataRow dataRowSample)
at Xceed.Grid.DetailGrid.UpdateDetailGridsOfMySelfAndSyncronizedChild()
at Xceed.Grid.DetailGrid.DataManager_DataRowsChanged(DataRowsChangedEventArgs e)
at Xceed.Grid.DataManager.InvokeOnDataRowsChanged(DataRowsChangedEventArgs e)
at Xceed.Grid.DataManager.CreateDataRows()
at Xceed.Grid.DataManager.ReadDataRows()
at Xceed.Grid.GridControl.OnBindingContextChanged(EventArgs e)

This occurs if I have the following code implemented in my main grid:

DeltaGrid deltaGrid = new DeltaGrid ();
this.DetailGridTemplates.Add (deltaGrid);

If these lines are commented out, the grid opens fine.

I have simplified the DeltaGrid as much as I can think to, and it still doesn’t work. Any ideas what may be causing this exception?

Nevermind I figured it out…I think there is some rule in programming that the likelihood of figuring out your bug increases exponentially the moment after you post a help request.
