Hi,
just share your aspx and cs code of page. so i can able to solve your problem.

Hi Sanjeeb,
              In the same app I have added an external Dll to convert page to pdf file.

Now the issue is if I use Session state to redirect Gridview to new page ,it redirects sucessfully, but if try to covert it to Pdf file on button click event..it just converts the button on page to pdf file...and loaded grid is not copied....

what is happening here i think..page is not maintaining the state on button click event...

plz sugest a solution..


the pdf dll is simple it just converts current page to pdf....

Thnx
Aman

Plz help
Thnx

Hi,
    Thx for reply,
     

Solved  now..:)

you want show the grid in another page or in same page.

if another page then pass the dropdown value as query string to new page on button click. catch that value in that page. and use it to bind the grid by passing it with select query.
