Add Checkbox to header of gridview
提问by C Sharper
I have following gridview:
我有以下网格视图：
I wanted to put checkbox to header of this grid, means below or besides Maths,Physics,Chemistry,Biology Header Text.
我想把复选框放在这个网格的标题中，意思是在数学、物理、化学、生物标题文本下方或之外。
Code for Grid:
网格代码：
<asp:GridView ID="GvSearch" runat="server" CellPadding ="3"
Width="100%" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lblCity" runat="server" Text='<%# Bind("City") %>' ></asp:Label>
<asp:CheckBox ID="ChkCity" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Maths">
<ItemTemplate>
<asp:Label ID="lblMaths" runat="server" Text='<%# Bind("Maths") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Physics">
<ItemTemplate>
<asp:Label ID="lblPhysics" runat="server" Text='<%# Bind("Physics") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Chemistry">
<ItemTemplate>
<asp:Label ID="lblChemistry" runat="server" Text='<%# Bind("Chemistry") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Biology">
<ItemTemplate>
<asp:Label ID="lblBio" runat="server" Text='<%# Bind("Biology") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I tried adding it as:
我尝试将其添加为：
<asp:TemplateField HeaderText="Physics">
<HeaderTemplate>
<asp:CheckBox ID="ChkCity" runat="server" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lblPhysics" runat="server" Text='<%# Bind("Physics") %>'></asp:Label>
</ItemTemplate>

Not sure, but I think the HeaderTextproperty in TemplateFieldmight be causing problems with the HeaderTemplate. Looking at a code sample on MSDN, they don't use HeaderTextwhen using the HeaderTemplate. Try something like this (not tested):
不确定，但我认为HeaderTextin的属性TemplateField可能会导致HeaderTemplate. 查看MSDN上的代码示例，他们HeaderText在使用HeaderTemplate. 尝试这样的事情（未测试）：
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="ChkCity" Text="Physics" runat="server" />
</HeaderTemplate>
<ItemTemplate>
....
</ItemTemplate>
</asp:TemplateField>
