find control in outer grid's editformtemple from inner grids update command

[aykut]

Hi,
I have a grid and its editformtemplate there is another grid. this inner grid maked inplace edits. I make manual update commands on inner grid to decide if I should update database or not. if I fond a problem and decide not to update database I set e.Canceled = True and want to show a warning label which is named lblneedTofindThisLabel below. Warning label is outside of inner gird, inside of formtemplate of outer grid. how can I find this control from inner grid's update command event ?

in other words:
    RadGridCompanies
        editformtemplate
            label
            InnerGrid (inplace edit)
                    Updateevent
                            -- must find label here.

             <FilterMenu EnableImageSprites="False">
             </FilterMenu>
         </telerik:RadGrid>

and the code is :

Protected Sub RadGridMids_UpdateCommand(sender As Object, e As GridCommandEventArgs)

      Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem)
      Dim ID_ As String = editedItem.OwnerTableView.DataKeyValues(editedItem.ItemIndex)("ID").ToString()

     ' .... some logic....

     ' -- WHAT X should be. ?

      Dim lblneedTofindThisLabel As Label = (TryCast(x.FindControl("lblneedTofindThisLabel"), Label))

      lblneedTofindThisLabel.visible=true
         end sub

nevermind.. I found it :) Interesting thing is I found solution in my own project which means I already sovled problem.

sorry...

For Each editedItemMain As GridEditFormItem In RadGridCompanies.MasterTableView.GetItems(GridItemType.EditFormItem)
               If editedItemMain.IsInEditMode Then
                   lblneedTofindThisLabel= (TryCast(editedItemMain.FindControl("lblneedTofindThisLabel"), Label))
               End If
           Next

Hello Aykut,

I'm glad you've managed to find a viable solution by yourself.
You can also try implementing a custom validator for similar scenarios:
