Need to launch user control as Edit form in RadGrid.

[Krish]

I have a requirement like this:
Having Edit template as a separe user control.
From Rad grid I am specifying "Edit Form" as this Edit template USer control.
But In runtime I need to launch Edit template user control with in different "mode.". 


My Example something like this..
<RadGrid>
--
--
<MasterTableView>
<GridEditColumn>
<GridEditFormSettings>
 <uc:EditTemplate Mode="UnRead" ... ; >
<ucEditTemplate Mode="Read"

Mode here is a public property of User control..which i will use to handle different panels..

SO,In a nutshell,How to change Edit template's property before that page launches?
Please help..! Tried item_bound,Item_created events..But not getting.. :(
