protected void anndelete_click(object sender, eventargs e) {             foreach (gridviewrow row in gridview1.rows)             {                 checkbox cb = (checkbox)row.findcontrol("chk_delete");                  if (cb.checked && cb != null)                 {                     {                         int id_no = convert.toint32(gridview1.datakeys[row.rowindex].value);                         mysqlcommand com = new mysqlcommand();                          com.commandtext = "delete announcement id = '" + id_no + "'";                         com.connection = con;                          //con.open();                         com.executenonquery();                         con.close();                         gridview1.datasource = null;                      }                  }              }             loadissuedata(); } 

assuming anndelete asp.net button control may put following code ask client confirmation:

html:

<asp:button id="anndelete" onclientclick="if(!confirm('confirm delete?')) return false;"></asp:button> 

return false avoid server side hit.
