代码如下：在模板列里有一个HeaderTemplate,里面包含一个CheckBox1,如果在单击checkBox1时让ItemTemplate里的CheckBox2全选呢？
<asp:DataGrid id=DataGrid1 style="Z-INDEX: 101; LEFT: 16px; POSITION: absolute; TOP: 88px" runat="server" AutoGenerateColumns="False" GridLines="None" DataSource="<%# dataSet11 %>">
<Columns>
<asp:TemplateColumn>
<HeaderTemplate>
<asp:CheckBox id="CheckBox1" runat="server"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox id="CheckBox2" runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn DataField="title_id" SortExpression="title_id" HeaderText="title_id"></asp:BoundColumn>
<asp:BoundColumn DataField="price" SortExpression="price" HeaderText="price"></asp:BoundColumn>
<asp:BoundColumn DataField="type" SortExpression="type" HeaderText="type"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
<asp:DataGrid id=DataGrid1 style="Z-INDEX: 101; LEFT: 16px; POSITION: absolute; TOP: 88px" runat="server" AutoGenerateColumns="False" GridLines="None" DataSource="<%# dataSet11 %>">
<Columns>
<asp:TemplateColumn>
<HeaderTemplate>
<asp:CheckBox id="CheckBox1" runat="server"></asp:CheckBox>
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox id="CheckBox2" runat="server"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
<asp:BoundColumn DataField="title_id" SortExpression="title_id" HeaderText="title_id"></asp:BoundColumn>
<asp:BoundColumn DataField="price" SortExpression="price" HeaderText="price"></asp:BoundColumn>
<asp:BoundColumn DataField="type" SortExpression="type" HeaderText="type"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
在ItemDataBound里写如下代码：
if((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
{
CheckBox chkb1 = (CheckBox)e.Item.FindControl("CheckBox1");
CheckBox chkb2 = (CheckBox)e.Item.FindControl("CheckBox2");
if(chkb1.checked == true)
{
chkb2.checked =true
}
}
