控制checkbox用JS:
function checkAll(checked, lstName) {
var input = document.getElementsByTagName("INPUT");
for (var i = 0; i < input.length; i++) {
if (lstName == null) {
input[i].checked = checked;
}
else if (input[i].type == "checkbox" && input[i].id.length > lstName.length && input[i].id.indexOf(lstName) > 0 ) {
input[i].checked = checked;
}
}
}
aspx：
<Columns>
<asp:TemplateField >
<HeaderTemplate >
<asp:CheckBox ID="lstChkAll" runat="server" onclick="checkAll(this.checked)" Text ="全选"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox runat ="server" ID="cboxTemple" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
删除么，直接用gridview的command事件后台处理

protected void cbSelectAll_CheckedChanged(object sender, EventArgs e) { foreach (GridViewRow gvr in gvList.Rows) { ((CheckBox)gvr.Cells[0].FindControl("cbSelect")).Checked = ((CheckBox)sender).Checked; } } protected void btnDelete_Click(object sender, EventArgs e) { foreach (GridViewRow gvr in gvList.Rows) { if (((CheckBox)gvr.Cells[0].FindControl("cbSelect")).Checked) { gvList.DeleteRow(gvr.DataItemIndex); } } }
