Replacing HeaderText with Headertemplate in TemplateField

问题

I have a gridview with templatefield columns. The TemplateFields are something like this:

<asp:TemplateField HeaderText="Title" SortExpression="name" meta:resourcekey="BoundFieldResource1">
                                <ItemTemplate>
                                    <asp:Label ID="lblTitle" runat="server" 
                                        Text='<%# Bind("Name") %>' 
                                        meta:resourcekey="BoundFieldResource1"></asp:Label>
                                </ItemTemplate>

I have to add a custom attribute for to the header of this columns so I removed HeaderText and added the following:

<Headertemplate>
         <asp:Label ID="lblTitleHeading" runat="server" Text="Title" data-custom="tbl-th_title_heading"></asp:Label>
</Headertemplate>

My problem is when I do this, it will break the sorting of that column and I cannot click on the header to sort it anymore, I tried changing the to but that didn't do anything. I would appreciate your answers.

回答1:

Ok I just found out how to do this, I just needed to change the Label to LinkButton and add CommandName="Sort" and CommandArgument="name" (or any SortExpression)

<Headertemplate>
     <asp:LinkButton ID="lblTitleHeading" runat="server" Text="Title" data-custom="tbl-th_title_heading" CommandName="Sort" CommandArgument="name"></asp:LinkButton>
