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.

' .... some logic....

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

lblneedTofindThisLabel.visible=true
