Dear Sir/Madam


I'm Maha From India.


Advance Thank you for Helping me


I have RadGrid1(using Mutiselect checkbox option) in my project


Problem : Label Text inside CommandItemTemplate not visible in after i click Delete(LinkButton1)
==================================================================
Inside CommandItemTemplate I have Label(lblmsg) to display some message to user for validation and DB Deleted Message


If user clicking LinkButton(LinkButton1) without seelcting any checkbox means I write validation 


That validation message will display on this lblmsg correctly


But if user select the check box and then click Delete means I want to show Confirmation message to user


Message format : Customer ID1,Customer ID2 deleted from DB succesfully


The above message will not visible in RadGrid


But If i debug means Thats Label Text Properly assigned using C#(RadGrid1_ItemCommand)


Note:
====
After execution of RadGrid1_ItemCommand() ->RadGrid1_NeedDataSource() method invoked Automatically


So My Doubt is  whether RadGrid Reassign my Label Text as Empty.


Becoz in Browser View Source <span id="RadGrid1_ctl00_ctl03_ctl01_lblmsg"></span>


Inside span my Text is not there
