Hello,

I would like to show any unsaved record by this code:
Private Sub ggc_QueryCellStyleInfo()
Dim rec As GridRecordRow = CType(IIf(TypeOf ggBusiness.Table.DisplayElements(e.TableCellIdentity.RowIndex) _
Is GridRecordRow, ggBusiness.Table.DisplayElements(e.TableCellIdentity.RowIndex), Nothing), GridRecordRow)
If Not rec Is Nothing Then

Dim dr As DataRowView = CType(IIf(TypeOf rec.GetData() Is DataRowView, rec.GetData(), Nothing), DataRowView)
If Not dr Is Nothing AndAlso dr.Row.RowState = DataRowState.Modified Then

e.Style.BackColor = Color.HotPink

Try
e.Style.CellTipText = String.Format("Previous Value: {0}", dr.Row(e.TableCellIdentity.ColIndex, DataRowVersion.Original).ToString)
Catch ex As IndexOutOfRangeException 'ChildColumn
End Try
e.Style.TextColor = Color.White
End If
End If

end sub

This code only works if user edit parent table, but didn't work for child table(backcolor didn't changed)
1. How to fix it to work on all edited tables?
2. How to change back color only on edited record field (not one row)?
3. How to make blinking cell appearance on edited cell(s) and show tooltiptext indicate original value?

Awaiting for your perfect solutions.

Best Regards and Thanks,
Harry

Hi Harry,

1. How to fix it to work on all edited tables?
2. How to change back color only on edited record field (not one row)?
>>>>>>>

You can try this code snippet.

Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As Syncfusion.WindowsForms.Grid.Grouping.GridTableCellStyleInfoEventArgs)
Dim el As Element = e.TableCellIdentity.DisplayElement
If elKind = Syncfusion.Grouping.DisplayElementKind.Record Then
Dim rec As Record = el.GetRecord()
If Not rec Is Nothing Then
Dim row As DataRowView = rec.GetData() as DataRowView
If row <> Nothing And row.Row.RowState = DataRowState.Modified Then
e.Style.BackColor = Color.Pink
End If
End If
End If
End Sub

and let me know if this helps.


3. How to make blinking cell appearance on edited cell(s) and show tooltiptext indicate original value?

Hello Haneef,

Thank you, it is helpful.
Would like to know how to make this code work on nested tables:
For Each record As SelectedRecord In selRecords 'del highlighted records only work on parent table
record.Record.Delete()
Next record

Last time you provide this code:
Dim el As Element = ggBusiness.Table.GetInnerMostCurrentElement() 'del rec on child/nested tables
If Not el Is Nothing Then
Dim rec As Record = el.GetRecord()
rec.Delete()
End If
But it can only delete one record each time.
I need to delete selected records work out on nested tables.
Thank you for your advise!

Best Regards,
Harry
