如何使用按钮填充 GridView 列

Question

我有以下GridView：

<asp:GridView ID="gvDispMsg" ClientIDMode="Static" ShowHeaderWhenEmpty="false" AlternatingRowStyle-BackColor="#EBE9E9" AutoGenerateColumns="false" EmptyDataText="There is no data to display" runat="server" AllowPaging="false" AllowSorting="true">
    <Columns>
        <asp:BoundField HeaderText="Delete Message" HeaderStyle-Width="12%" />
        <asp:BoundField HeaderText="ID" HeaderStyle-Width="12%" DataField="ID" />
        <asp:BoundField HeaderText="Date" HeaderStyle-Width="13%" DataField="Created" />
        <asp:BoundField HeaderText="Message" HeaderStyle-Width="45%" DataField="Message" />
        <asp:BoundField HeaderText="Active" HeaderStyle-Width="10%" DataField="Active" />
        <asp:BoundField HeaderText="Created By" HeaderStyle-Width="20%" DataField="CreatedBy" />
    </Columns>
</asp:GridView>

它是从在代码隐藏中执行的 SQL 表中填充的。唯一未填充的列是 Delete Message 列。

如何为Delete Message 列中的每一行添加一个按钮，该按钮采用ID 数据字段的参数？

Answer 1

添加

<asp:GridView AutoGenerateDeleteButton="true" DataKeyNames="ID" OnRowDeleted="NewEvent"

并在 CodeBehind 中处理 NewEvent

或

添加 <asp:ButtonField ButtonType="Button" CommandName="delete" Text="Delete" HeaderText="Delete"/> 而不是 BoundField

或

添加

<asp:TemplateField HeaderText="Delete">
    <ItemTemplate>
        <asp:Button ID="lbiDelete" runat="server" CommandName="Delete" CommandArgument='<%# Bind("ID") %>' />
    </ItemTemplate> 
    <EditItemTemplate>
        <asp:Button ID="lbiDelete" runat="server" CommandName="Delete" CommandArgument='<%# Bind("ID") %>' />
    </EditItemTemplate>
    <FooterTemplate>
        <asp:Button ID="lbiDelete" runat="server" CommandName="Delete" CommandArgument='<%# Bind("ID") %>' />
    </FooterTemplate>                  
</asp:TemplateField>
