ASP.Net GridView 基础 Template模板

一、了解Template

AlternatingItemTemplate定义交替行的内容和外观，如果没有规定模板，则使用ItemTemplate；
EditItemTemplate定义当前正在编辑的行的内容和外观。该模板包含输入字段，而且还可能包含验证程序；
FooterTemplate定义该行的页脚的内容和外观；
HeaderTemplate定义该行的标题的内容和外观；
ItemTemplate定义该行的默认内容和外观。

二、模板应用

aspx代码

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
            DataKeyNames="ConferenceNo,VerNum,AttendeeCategory,Attendee"
            DataSourceID="SqlDataSource1" onrowcommand="GridView1_RowCommand"
            onrowdatabound="GridView1_RowDataBound"
            onrowcreated="GridView1_RowCreated">
            <Columns>
                其它字段
                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="btnDel" runat="server"
                            CommandArgument='<%# Eval("ConferenceNo") %>' onclick="btnDel_Click"
                            Text="del" />
                        <asp:LinkButton ID="LinkButton1" runat="server"
                            CommandArgument='<%# Eval("ConferenceNo") %>' CommandName="2">Link1</asp:LinkButton>
                        <asp:LinkButton ID="LinkButton2" runat="server" CommandName="3">Link2</asp:LinkButton>
                        <asp:LinkButton ID="LinkButton3" runat="server"
                            CommandArgument='<%# ((GridViewRow)Container).RowIndex %>' CommandName="4">Link3</asp:LinkButton>
                        <asp:LinkButton ID="LinkButton4" runat="server">Link4</asp:LinkButton>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:ButtonField CommandName="1" Text="按钮"  />
            </Columns>
        </asp:GridView>
