---code behind

protected void sellectAll(object sender, EventArgs e)
        {
            CheckBox ChkBoxHeader = (CheckBox)GridZeroApprovedKm.HeaderRow.FindControl("chkb1");
            foreach (GridViewRow row in GridZeroApprovedKm.Rows)
            {
                CheckBox ChkBoxRows = (CheckBox)row.FindControl("chkb2");
                if (ChkBoxHeader.Checked == true)
                {
                    ChkBoxRows.Checked = true;
                }
                else
                {
                    ChkBoxRows.Checked = false;
                }
            }
        }

- 当我点击标题复选框时

- 检查gridview的所有复选框....但页面刷新....我已将autopostback属性设为true。为什么刷新？

--when i click the header checkbox
--it checks all the checkbox of the gridview....but the page is refreshed....i have made the autopostback property as true. Why does it refresh ?
