很简单的方法,就是用js实现:

页面:

AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False">

后台代码:

private void dgUserList_PreRender(object sender, System.EventArgs e)

{

foreach (DataGridItem item in dgUserList.Controls[0].Controls)

{

if (item.ItemType == ListItemType.Header)

{

CheckBox chkAll=(CheckBox)item.FindControl("chkAll");

System.Text.StringBuilder strScript = new System.Text.StringBuilder(" \n");

if(!Page.IsClientScriptBlockRegistered("checkStatus"))

Page.RegisterClientScriptBlock("checkStatus",strScript.ToString());

chkAll.Attributes.Add("onclick","checkStatus()");

return;

}
