How to update the cell content on AddNewRecord in WinForms GridGroupingControl?
Update cell content on AddNewRecord
In order to update a computed value in the WinForms Grid Control part which is being added, it can be done using the QueryCellStyleInfo event. In this article, the cell value of a record is being updated in another cell value depending upon the value specified.
C#
// Form()
// Hook the required event.
this.gridGroupingControl1.QueryCellStyleInfo += new GridTableCellStyleInfoEventHandler(gridGroupingControl1_QueryCellStyleInfo);
// Specify the criteria for updating.
void gridGroupingControl1_QueryCellStyleInfo(object sender, GridTableCellStyleInfoEventArgs e)
{
double temp = 0.0;
GridCurrentCell cc = this.gridGroupingControl1.TableControl.CurrentCell;
if (e.TableCellIdentity.TableCellType == GridTableCellType.AddNewRecordFieldCell && e.TableCellIdentity.Column.Name == "SampleData")
{
Element el = e.TableCellIdentity.DisplayElement;
Record r = el.GetRecord();
object ACol = r.GetValue("CategoryName");
//The cellvalue to be computed and updated value.
if (r != null && ACol != null && (double.TryParse(ACol.ToString(), out temp)))
{
object ob = (temp * 0.4).ToString();
e.Style.CellValue = ob.ToString();
}
}
}
VB
' Form()
' Hook the required event.
AddHandler gridGroupingControl1.QueryCellStyleInfo, AddressOf gridGroupingControl1_QueryCellStyleInfo
' Specify the criteria for updating.
Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As GridTableCellStyleInfoEventArgs)
Dim temp As Double = 0.0
Dim cc As GridCurrentCell = Me.gridGroupingControl1.TableControl.CurrentCell
If e.TableCellIdentity.TableCellType = GridTableCellType.AddNewRecordFieldCell AndAlso e.TableCellIdentity.Column.Name = "SampleData" Then
Dim el As Element = e.TableCellIdentity.DisplayElement
Dim r As Record = el.GetRecord()
Dim ACol As Object = r.GetValue("CategoryName")
'The cellvalue to be computed and updated value.
If r IsNot Nothing AndAlso ACol IsNot Nothing AndAlso (Double.TryParse(ACol.ToString(), temp)) Then
Dim ob As Object = (temp * 0.4).ToString()
e.Style.CellValue = ob.ToString()
End If
End If
End Sub
