How to handle the activating or deactivating the current cell exception in WinForms GridControl?

Platform: WinForms |
Control: GridControl |
Published Date: April 30, 2011 |

Steps for handle the exception

When you try to add a row to the GridControl, it resets the CurrentCell that causes a problem at the middle of activating or deactivating the CurrentCell.

Solution

You can avoid this by working directly with the grid’s GridData object.

C#

//add the row
this.gridControl1.Model.Data.RowCount += 1;

 

VB

'add the row
Me.gridControl1.Model.Data.RowCount += 1

 

You can also achieve this by locking the CurrentCell before incrementing the RowCount and unlock after that.

C#

//lock and unlock the cell while add the row
this.gridControl1.CurrentCell.Lock();
this.gridControl1.RowCount += 1;
this.gridControl1.CurrentCell.Unlock();

 

VB

'lock and unlock the cell while add the row
Me.gridControl1.CurrentCell.Lock()
Me.gridControl1.RowCount += 1
Me.gridControl1.CurrentCell.Unlock()
