How to make the cells ReadOnly in WinForms GridGroupingControl?
Make the cells into readonly
In GridGroupingControl, you can make the cell read-only by setting the ReadOnly Property in the Grid model or by using the QueryCellStyleInfo Event.
By using GridModel
C#
// Column can be index or column MappingName
gridGroupingControl1.TableDescriptor.Columns[Column].Appearance.AnyRecordFieldCell.ReadOnly = true;
VB
' Column can be index or column MappingName
gridGroupingControl1.TableDescriptor.Columns(Column).Appearance.AnyRecordFieldCell.ReadOnly = True
By using QueryCellStyleInfo
C#
void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
// The cell is set to be Readonly
if (e.TableCellIdentity.RowIndex == 6 && e.TableCellIdentity.ColIndex == 3)
{
e.Style.BackColor = Color.Yellow;
e.Style.ReadOnly = true;
}
// The row is set to be Readonly
if (e.TableCellIdentity.RowIndex == 4)
{
e.Style.BackColor = Color.LightGray;
e.Style.ReadOnly = true;
}
// The Column is set to be Readonly using index
if (e.TableCellIdentity.ColIndex == 4)
{
e.Style.BackColor = Color.Aqua;
e.Style.ReadOnly = true;
}
// The Column is set to be Readonly using Column MappingName
if (e.TableCellIdentity.Column!= null)
{
if (e.TableCellIdentity.Column.Name == "City")
{
e.Style.BackColor = Color.Aqua;
e.Style.ReadOnly = true;
}
}
//Range of cell is set to be Readonly
if ((e.TableCellIdentity.RowIndex == 7 || e.TableCellIdentity.RowIndex == 8) && (e.TableCellIdentity.ColIndex == 1 || e.TableCellIdentity.ColIndex == 2))
{
e.Style.BackColor = Color.LightPink;
e.Style.ReadOnly = true;
}
}
VB
Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs)
' The cell is set to be Readonly
If e.TableCellIdentity.RowIndex = 6 AndAlso e.TableCellIdentity.ColIndex = 3 Then
e.Style.BackColor = Color.Yellow
e.Style.ReadOnly = True
End If
' The row is set to be Readonly
If e.TableCellIdentity.RowIndex = 4 Then
e.Style.BackColor = Color. LightGray
e.Style.ReadOnly = True
End If
' The Column is set to be Readonly using index
If e.TableCellIdentity.ColIndex = 4 Then
e.Style.BackColor = Color.Aqua
e.Style.ReadOnly = True
End If
' The Column is set to be Readonly using Column MappingName
If e.TableCellIdentity.Column IsNot Nothing Then
If e.TableCellIdentity.Column.Name = "City" Then
e.Style.BackColor = Color.Aqua
e.Style.ReadOnly = True
End If
End If
'Range of cell is set to be Readonly
If (e.TableCellIdentity.RowIndex = 7 OrElse e.TableCellIdentity.RowIndex = 8) AndAlso (e.TableCellIdentity.ColIndex = 1 OrElse e.TableCellIdentity.ColIndex = 2) Then
e.Style.BackColor = Color. LightPink
e.Style.ReadOnly = True
End If
End Sub
