Hi @Gani_tpt,

This is the same way you saved all your page data before.

If you want to operate on all pages, you can use this method.

You can use the command below to browse all pages and browse all rows in each page. You can also get the current page before doing this and return there after looping through everything.

protected void btnClear_Click(object sender, EventArgs e)
 {
     int a = gvCustomer.PageIndex;
     //Loop through All Pages
     for (int i = 0; i < gvCustomer.PageCount; i++)
     {
         //Set Page Index
         gvCustomer.SetPageIndex(i);
         //After Setting Page Index Loop through its Rows
         foreach (GridViewRow gvrow in gvCustomer.Rows)
         {
             if (gvrow.RowType == DataControlRowType.DataRow)
             {
                 CheckBox chk = (CheckBox)gvrow.FindControl("CheckBox1");
                 chk.Checked = false;
             }
         }
     }
     gvCustomer.SetPageIndex(a);
 }
