Hi Selva,

You need to specify the trigger control inside tag.
-------------------------------------------------------

Update Panel Section

---

Controls inside "ContentTemplate" tag can be modified without complete postback
with updatePanel.

---

See, No postback here!

-------------------------------------------------------
Also,I've created a sample app for demonstration purposes. Find it attached here and go through.

Happy Coding :)

i want to insert the data to database without page refresh.. when i using postpack trigger every time page get refreshed...can u give me the reference..

Hi,

write a trigger in update panel and pass the button id to it.

        Buttoncptrolid" />
