ASP.Net GridView 基礎 Template模板

一、了解Template

AlternatingItemTemplate定義交替行的內容和外觀，如果沒有規定模板，則使用ItemTemplate；
EditItemTemplate定義當前正在編輯的行的內容和外觀。該模板包含輸入字段，而且還可能包含驗證程序；
FooterTemplate定義該行的頁腳的內容和外觀；
HeaderTemplate定義該行的標題的內容和外觀；
ItemTemplate定義該行的默認內容和外觀。

二、模板應用

 

 

aspx代碼

<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="按鈕"  />
            </Columns>
        </asp:GridView>
