RadGrid cannot get the savedoldvalues

[Wilson]

Hi,

The "SavedOldValues"  returns empty hashtable.
Please help.  

Private Sub GridViewControl_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles GridViewControl.ItemCommand

If (e.CommandName = RadGrid.UpdateCommandName) Then

If (e.Item.GetType.ToString = "Telerik.Web.UI.GridEditFormItem") Then

Dim editedItem As GridEditFormItem = CType(e.Item, GridEditFormItem)

_Session(

"RadGrid.SavedOldValues") = editedItem.SavedOldValues

End If

End If

End Sub

Hello Wilson,

The approach in question is applicable for autogenerated column editors, as described in this article. If using a template column, the approach is slightly different.
Let me know if this information helps.

Hi,

The AutoGenerateColumns was set to "true"

It works fine with _Grid.MasterTableView.EditMode=GridEditMode.InPlace

But, it doesn't work with GridEditMode.EditForms

Any trick?

Thanks,
Wilson

Have you set AllowAutomaticUpdates = true for the master table in the grid? I noticed that in your code snippet from the help topic and it is probably an important part of the implementation. Also make sure that you bind the grid with NeedDataSource event handling.
