[Ramya]

HI,
Can you Please help me in solving the problem.

Controller->Homecontroller corresponding view->Home
In home controller i have used CRUD operations,followed by HTML controls.
The functionality of that page working fine.Now im trying to do that same by using rad controls
i just tried to create a new record for Radcontroller
Controller->RadController corresponding views->rad
for that i have taken radtextboxes
but here i couldnt get the values that are inserted into the radtextboxes,
throwing error like null values can not insert,insertion failed.if i use normal html for that working well.
Create.aspx in view.
