How to ignore column when editing

[Bruce Hochstetler]

Hi,

I data bind my grid with a DataTable that has a column that holds an object that contains information on that row of data. In the grid I obviously don't display it (Display="false" Visible="false" ReadOnly="true"). When I do an 'Add', I get the 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'AttachmentInfo' error. Does anyone know of a way to get the insert edit panel to ignore this column?

Thanks,
Bruce

Hello Bruce,

The reason for this error and the solution for it are explained in this article from the online documentation:

http://www.telerik.com/help/aspnet-ajax/grderrormessages.html

In cases when you have custom collection of objects for grid source, you can create an empty instance of this object inside the ItemCommand handler on init insert action. Here is some pseudo code:

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.ItemCommand
  If e.CommandName = RadGrid.InitInsertCommandName Then '"Add new" button clicked
    e.Canceled = True
    'Prepare an IDictionary with the predefined values
     Dim myObj As [My_Obj_Type_Here]= New [My_Obj_Type_Here]()
     'Insert the item and rebind
     e.Item.OwnerTableView.InsertItem(myObj)
  End If
End Sub
