Cell Validating keep edit in current cell

[Armand]

I am trying to set edit back to cell if no value is entered.
I am using the validating event.
It traps the empty event nicely but when I try to move focus and edit back to the empty cell if refuses and jump to next column in same row.
My code is as follow:

'get column number
        Dim col As Int32 = Me.RadGridView1.Columns.IndexOf(Me.RadGridView1.CurrentColumn)
        'test first if valid lognumber
        If col = 0 Then
            Dim input As String = (Me.RadGridView1.ActiveEditor.Value.ToString())
            If input = "" Then
                MsgBox("empty")
                e.Cancel = True
                Me.RadGridView1.Rows(0).IsCurrent = True
                Me.RadGridView1.Columns(0).IsCurrent = True
                Me.RadGridView1.BeginEdit()
            End If
        End If

Thank you

Hi Armand,

Thank you for the question.

RadGridView does not currently support this behavior. However, there is a way to prevent the user from leaving the cell in case of incorrect input. Basically, you can implement an additional form that serves as a row editor for the values being input into the cell. Your validation logic should be implemented in this form. Then, when you want to edit a cell, this form will open in Dialog Mode and you will be able to close it only if the input is correct. 

You can learn more about Custom Row Editors here: Custom Row Editor for RadGridView. This approach could be used as a base for your custom validation form.

I hope this will help you. Do not hesitate to write back if you need further assistance.
