Hi everyone.

I have this issue, and i'm trying to deal with it for the last 3 days now, no solution found.
My grid is loaded using an DataAdapter.

When I edit the items in the grid,and fire the update command, the data in my database will not be updated.
This is until i move the grid one row. Then it will accept changes made. So i'm struggeling here to find a way out.

Could you please provide me some sample or solution for this?
Btw, i'm using VB.NET for this.

Hi Steve,

I haven't heard of this situation before to be honest. It sounds very strange. If you could post some code to replicate it, I'll have a look at it first thing for you. In the meantime, I'd suggest wrapping any updates to your grid in

Using Me.radGridView1.Deferrefresh()
' Some update to grid
End Using

this may hep, but without seeing an example, it may be tricky to sort out.
Best regards,
Richard

I currently use this code:

Dim cmd As System.Data.Odbc.OdbcCommand
Dim adp As System.Data.Odbc.OdbcDataAdapter
Dim ds As New DataSet
'
Private Sub FormLoader() Handles MyBase.Load
    cn.Open()
    cmd = New System.Data.Odbc.OdbcCommand("SELECT * FROM TABLE", cn)
    adp = New System.Data.Odbc.OdbcDataAdapter(cmd)
    adp.Fill(ds, "TABLE")
    '
    Me.RadGridView1.AutoGenerateColumns = True
    Me.RadGridView1.DataSource = ds
    Me.RadGridView1.DataMember = "TABLE"
End Sub
 
Private Sub RadButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadButton1.Click

    Dim cmdbuilder As New System.Data.Odbc.OdbcCommandBuilder(adp)
    Dim i As Integer
 
    i = adp.Update(ds, "TABLE")
    MsgBox("Records Updated= " & i)
End Sub

Witch works fine for me. Expect that i always need to change a row before it updates.
I'm used to working with the VB.NET Datagridview, where this code always did the job like i wanted it to be.

Thank you for your help.

Hello Steve,

Are yous still in edit mode while pressing the save button?

Try calling an EndEdit() or if this failes, try adding a BeginUpdate(); EndUpdate(true) in the first lines of your ButtonClick.

Please let me know if this works for you.

Hi.

Yes, i tryed all of those options, none of them seem to work.
It seems that for some reason the editor only exits when i move a row.
Whatever i try, it wont let me update without moving a row.

Hello.

This is my designer file

<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class frm_goederen
   
* Client requests privacy about his code.

End Class

And here is my code:

Public Class frm_goederen
 
*Client requests privacy about his code
 
End Class

There is a DataSet3 included, but is not used at all.

When i try the same thing with a REGULAR DataGridView, i use this code:

Private Sub RadButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadButton1.Click
        DataGridView1.EndEdit()
        UpdateGrid()
    End Sub
 
    Private Sub UpdateGrid()
        Dim cmdbuilder As New System.Data.Odbc.OdbcCommandBuilder(adp2)
        Dim i As Integer
        Try
            i = adp2.Update(ds2, "TABLE")
            MsgBox("Aantal wijzigingen doorgevoerd: " & i, MsgBoxStyle.Information + MsgBoxStyle.OkOnly, "Success")
        Catch ex As Exception
            MsgBox(ex.Message, MsgBoxStyle.Critical + MsgBoxStyle.OkOnly, "Oeps...")
        End Try
    End Sub

And it's working the way it should be working.

So i cant figure it out at all...

Thank you for your time

Hi Steve,

Sorry about the delay in getting back to you. I haven't been able to run your project at the moment, but may I suggest
  • Disable your button
  • Subscribe to the CellEndEdit event.
  • In there, re-enable your button and give it a click (removing theDataGridView1.EndEdit() line)

Let me know if that helps at all.
Richard

Hi Steve,

This sounds very odd. After you update, please can you also try calling
Me.RadGridView1.CurrentRow.InvalidateRow()

We have never expienced this issue before, but I don't have any DB access today as I'm at home so can't try it. Let me know if this help.

Thanks
Richard

Hi steve,

In this scenario the edit operation depends on the bound object that in your case is DataTable/DataSet. DataRow/DataRowView objects implement IEditableObject and when some data in RadGridView is changed, the internal CurrencyManager calls EndEdit of current item after the current position is changed to another row.

If you want to apply your changes immediately, you can use following code snippet:

Dim editableObject As IEditableObject = TryCast(Me.radGridView1.CurrentRow.DataBoundItem, IEditableObject)
If editableObject IsNot Nothing Then
    editableObject.EndEdit()
End If

I hope this helps.

Hi Drago,

Thank you for writing.

We have a documentation article providing examples how the database can be updated handling various scenarios: https://feedback.telerik.com/Project/154/Feedback/Details/203285-fix-radgridview-the-last-row-is-not-updated-when-the-grid-is-bound-to-ieditabl.

In case you are using an older version of the controls you can check the following feedback item. The issue was resolved in the R3 2016 SP1 version of the suite.

I hope this helps. Should you have further questions please do not hesitate to write back.

    dgErrors.ClearSelection()
    dgErrors.CurrentCell = Nothing

 

this worked for me, though i didnt try any of the other suggestions.

It effectively moves your selected row , and the problems goes away
