Implement Search and Client Side Paging of GridView inside jQuery Dialog Modal Popup in ASP.Net

Hi@Shashikant,

Thank you fo replying .

here  i want to stable the checkbox checked when i do paging in gridview.

For example :

gridview1 inside

modalpopupextender1 updatepanel

gridview1 page :1

name  selectuser

jhon   chckbox1.checked =true

mary  chckbox1.checked =true

gaint  chckbox1.checked =false

jack    chckbox1.checked =true

peter   chckbox1.checked =false

gridview1 Page :2

name  selectuser

james    chckbox1.checked =false

smith     chckbox1.checked =true

samson   chckbox1.checked =false

sam        chckbox1.checked =false

watson     chckbox1.checked =true

like this

 **what is my problem is after selecting checkboxes in page1

and going to select page 2 and there i will check some checkboxes

now again i going to select page 1, now the checkboxes are not checked what i already checked before going to page 2.

while paging my values of checkboxes are not stable here,

this is exact what i want.

this below code is how i used pageindexchanging .

 protected void grdUser_PageIndexChanging1(object sender, GridViewPageEventArgs e)
        {
            this.BindUser();
            grdUser.PageIndex = e.NewPageIndex;
            DataBind();
            this.mpe.Show();

        }

Thank you in advance
