在Gridview中标识特定记录的访问密钥(对于按钮/TemplateField)

本文关键字：于按钮 按钮 TemplateField 密钥 访问 标识 Gridview 记录 | 更新日期: 2023-09-27 18:30:06

我正在尝试使用SqlDataSource导入一个包含动态数据的网格视图，再加上两个TemplateFields，其中包含Accept和Decline这两个按钮。我需要做的是更新表中记录来源的特定列。（在名为"已接受"的列中，将值从Null更改为1或0）

Q.）我需要一种方法来识别将单击哪个按钮的行？（需要识别特定行的访问密钥的值）

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="request_no" DataSourceID="SqlDataSource1" Font-Names="Tahoma" Font-Size="Small" ForeColor="#333333" GridLines="None" OnSelectedIndexChanged="GridView1_SelectedIndexChanged1" OnRowCommand="GridView1_RowCommand" OnRowDataBound="GridView1_RowDataBound">

                        <Columns>
                            <asp:BoundField DataField="request_no" HeaderText="request_no" ReadOnly="True" SortExpression="request_no" />

在Gridview中标识特定记录的访问密钥(对于按钮/TemplateField)

您非常接近，只是缺少CommandArgument:

                       <asp:TemplateField>
                            <ItemTemplate>
                                <asp:Button ID="AcceptRequest" runat="server" 
                                   OnClick="AcceptRequest_Click" Text="Accept" 
                                   CommandName="AcceptRequestcmd" 
                                   CommandArgument="<%# Eval("request_no") %> />
                            </ItemTemplate>
                        </asp:TemplateField>

（假设request_no是行标识符）

然后只是

protected void GridView1_RowCommand(...)
{
   switch ( e.CommandName )
   {
      case "AcceptRequestcmd" :
         string rowid = e.CommandArgument;
   }
}
