        }
        else if (((CheckBox)e.Item.FindControl("CheckBox2")).Checked == false)
        {
            Response.Write("<script>alert('NOT Checked')</script>");

        }
    }
}

protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
{
    if (((CheckBox)sender).Checked == true)
    {
                 Response.Write("<script>alert('Checked')</script>");
    }
    else
    {
        Response.Write("<script>alert('NOT Checked')</script>");

    }
}

<asp:DataGrid ID="DataGrid1" runat="server"

    DataSourceID="SqlDataSource1" onitemcreated="DataGrid1_ItemCreated"

          onitemdatabound="DataGrid1_ItemDataBound"  ClientIDMode="Static" >
          <Columns>
              <asp:TemplateColumn HeaderText="test">
                  <HeaderTemplate >
                      <asp:CheckBox ID="CheckBox2" runat="server" ClientIDMode="Static"

                          oncheckedchanged="CheckBox2_CheckedChanged" />

                  </HeaderTemplate>
              </asp:TemplateColumn>
          </Columns>
    </asp:DataGrid>

据我所知，您希望将gridview标题中的复选框绑定.
1)将复选框(首选HTML)添加到gridview标头模板.
2)处理gridview的rowdatabound事件.
3)在上述事件中找到该复选框.
4)将数据相应地绑定到它.

如果我错了，那就对了....

as per my understanding you want to bind the checkbox in the header of the gridview.
1)add the checkbox (HTML preferred) to the gridview headertemplate.
2)handle the rowdatabound event of the gridview.
3)find the checkbox in above event.
4)bind the data accordingly to it.

correct if I am wrong....
