Making Infragistics ultrawingrid, desired columns readonly
- by Amit Ranjan
I am stucked at the situation where I need to disable few columns of a each row ,except newly added row.
That is I have 10 columns in grid and I want first three columns that are binded from the rows coming from db as disabled or read-only, rest are editable. if I add new row then all columns of new row must be enabled until and unless it is saved.
I dont have any DataKey or Primary key for my existing row or new row. I have to check for some boolean values like IsNewRow.
in my current scenario i am using this code block
Private Sub dgTimeSheet_InitializeRow(ByVal sender As Object, ByVal e As Infragistics.Win.UltraWinGrid.InitializeRowEventArgs) Handles dgTimeSheet.InitializeRow
''if either column key is Project, Class or Milestone
'' Activation.NoEdit = Disable and Activation.AllowEdit = Enable
Dim index As Integer = e.Row.Index
If e.Row.IsAddRow Then
dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.AllowEdit
dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.AllowEdit
dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.AllowEdit
Else
dgTimeSheet.Rows(index).Cells(PROJECT).Activation = Activation.NoEdit
dgTimeSheet.Rows(index).Cells(SERVICE_ISSUE_CLASS).Activation = Activation.NoEdit
dgTimeSheet.Rows(index).Cells(MILESTONE).Activation = Activation.NoEdit
End If
CheckRows()
End Sub
but the problem is that if i click on disabled/readonly rows then newly added rows also gets disabled., which i dont want
