Restrict the editing option of grid
You can restrict the editing option of the current cell by using the following methods. The AllowEdit, ReadOnly and CurrentCellStartEditing event are used to disable the editing of the grid cell.
Using AllowEdit Property
By using this property, the current cell enters to the edit mode, but you cannot edit the content of it.
C#
//Disable the Editing of the table content this.gridGroupingControl1.TableDescriptor.AllowEdit = false;
VB
'Disable the Editing of the table content Me.gridGroupingControl1.TableDescriptor.AllowEdit = False
Using CurrentCellStartEditing Event
This event triggers while the cell is entering to the edit mode. By cancelling this event you can prevent the editing of the grid cell.
C#
//Hook this event to prevent the current cell from editing. this.gridGroupingControl1.TableControl.CurrentCellStartEditing += TableControl_CurrentCellStartEditing; void TableControl_CurrentCellStartEditing(object sender, CancelEventArgs e) { //Cancel the editing of the current cell e.Cancel = true; }
VB
'Hook this event to prevent the current cell from editing. Private Me.gridGroupingControl1.TableControl.CurrentCellStartEditing += AddressOf TableControl_CurrentCellStartEditing Private Sub TableControl_CurrentCellStartEditing(ByVal sender As Object, ByVal e As CancelEventArgs) 'Cancel the editing of the current cell e.Cancel = True End Sub
Using QueryCellStyleInfo Event
By setting the “ReadOnly” property value as true, you cannot change the content of the cell.
C#
//Hook the event to change the particular cell style this.gridGroupingControl1.QueryCellStyleInfo += gridGroupingControl1_QueryCellStyleInfo; void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e) { if (e.TableCellIdentity.ColIndex == 3) { e.Style.ReadOnly = true; } }
VB
'Hook the event to change the particular cell style Private Me.gridGroupingControl1.QueryCellStyleInfo += AddressOf gridGroupingControl1_QueryCellStyleInfo Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs) If e.TableCellIdentity.ColIndex = 3 Then e.Style.ReadOnly = True End If End Sub
