Q> 我想将GridView按钮的文本显示为硬编码,并在按钮点击时显示要触发的事件。怎么做到这一点?

直到现在我能够走到这一步

GridView Sample

但我想将按钮文字显示为读取删除而不是“读取/删除”列中的值。 我用过的代码

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
DataKeyNames="MID" DataSourceID="inbox" EnableModelValidation="True" 
onselectedindexchanged="GridView1_SelectedIndexChanged">
<Columns>
<asp:ButtonField ButtonType="Button" DataTextField="MID" HeaderText="Read" 
  Text="Read" />
<asp:BoundField DataField="MID" HeaderText="MID" InsertVisible="False" 
  ReadOnly="True" SortExpression="MID" />
<asp:BoundField DataField="sender" HeaderText="sender" 
  SortExpression="sender" />
<asp:BoundField DataField="subject" HeaderText="subject" 
  SortExpression="subject" />
<asp:BoundField DataField="on" HeaderText="on" SortExpression="on" />
<asp:ButtonField ButtonType="Button" DataTextField="MID" HeaderText="Delete" 
  Text="Delete" />
</Columns>
</asp:GridView>

<asp:SqlDataSource ID="inbox" runat="server" 
ConnectionString="<%$ ConnectionStrings:connectionString %>" 
SelectCommand="SELECT [MID], [sender], [subject], [on] FROM [mail]">
</asp:SqlDataSource>

如果您希望文本显示为“删除”或“读取”,则只需将DataTextField属性设置为使用结果的MID属性,而不是设置{{ 1}}属性如此:

CommandName

就处理按钮的<asp:ButtonField ButtonType="Button" CommandName='<%#Eval("MMID")%>' HeaderText="Delete" Text="Delete" /> 事件而言,您可以在GridView上处理OnClick事件:

OnRowCommand

现在添加代码:

<asp:GridView ID="GridView1" runat="server" OnRowCommand="GridView_RowCommand" AutoGenerateColumns="False"

以上代码不起作用。 ButtonField和乳头对男人一样有用。而是使用ItemTemplateField:

protected void GridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{

  string MMID = e.CommandName;
  if( (e.CommandSource as ButtonField).Text=="Delete")
  {
             //oh, I should delete this MMID
  }
}    

然后GridView_RowCommand变为:

 <asp:TemplateField>
     <ItemTemplate>
         <asp:Button ID="btn" runat="server" CommandName="Delete" CommandArgument='<%#Eval("MID") %>'
                    Text="Delete" />
     </ItemTemplate>
 </asp:TemplateField>
