Hello Experts:

I'm trying to highlight a row inside a editable datagrid.  When the user clicks "edit" I'd like to highlight that row until they click "update" or "cancel".  I'll include my code below.  I'm looking for a solution in VB.Net.  I find a lot of solutions online that are for C#.

Thanks for your help!

Here are my subs for editing and updating:

Edit:

Sub DataGrid_Edit(Sender As Object, E As DataGridCommandEventArgs)
   
                        ' turn on editing for the selected row
   
                       
                Dim CommentBox As Textbox
                          DataGrid1.EditItemIndex = e.Item.ItemIndex
                          Dim scriptJs As String
                                    
      BindGrid()
                              
      CommentBox = CType(DataGrid1.Items(DataGrid1.EditItemIndex).Cells(7).Controls(0), TextBox)
      scriptJs = "<script language=javascript>" & vbCrLf
      scriptJs &= "document.getElementById('" & CommentBox.UniqueID & "').focus();" & vbCrLf
      scriptJs &= "document.getElementById('" & CommentBox.UniqueID & "').select();" & vbCrLf
      scriptJs &= "<" & "/script>"
      If (Not Me.IsStartupScriptRegistered("Startup")) Then
      Me.RegisterStartupScript("Startup", scriptJs)
      End If
                              
        End Sub

Update:
               Sub DataGrid_Update(Sender As Object, E As DataGridCommandEventArgs)
   
                        ' update the database with the new values
   
                        ' get the edit text boxes
                        Dim Control As String = CType(e.Item.Cells(0).Controls(0), textbox).Text
                        Dim CommentBox As String = CType(e.Item.Cells(7).Controls(0), textbox).Text
   
                        ' TODO: update the Command value for your application
                        Dim myConnection As New SqlConnection(ConnectionString)
                        Dim UpdateCommand As SqlCommand = new SqlCommand()
                        UpdateCommand.Connection = myConnection
   
                        If AddingNew = True Then
                            UpdateCommand.CommandText = "INSERT INTO comments1130(ControlNo, CommentBox) VALUES (@Contno, @CommentBox)"
                        Else
                            UpdateCommand.CommandText = "UPDATE comments1130 SET CommentBox = @CommentBox WHERE controlNo = @ContNo"
                        End If
                        UpdateCommand.Parameters.Add("@ContNo", SqlDbType.VarChar, 8000).Value = Control
                        UpdateCommand.Parameters.Add("@CommentBox", SqlDbType.VarChar, 99).Value = CommentBox
   
                        ' execute the command
                        Try
                            myConnection.Open()
                            UpdateCommand.ExecuteNonQuery()
   
                        Catch ex as Exception
                            Message.Text = ex.ToString()
   
                        Finally
                            myConnection.Close()
   
                        End Try
   
                        ' Resort the grid for new records
                        If AddingNew = True Then
                            DataGrid1.CurrentPageIndex = 0
                            AddingNew = false
                        End If
   
                        ' rebind the grid
                        DataGrid1.EditItemIndex = -1
                        BindGrid()
               End Sub

And finally the datagrid:
