推荐答案

GridView.RowCommand事件 [ ^ ]将处理按钮点击。



您需要在GridView MarkUp中添加一个属性 onrowcommand =MyGridView_RowCommand。



并在Code Behind中定义事件如下。

The GridView.RowCommand Event[^] will handle the button click.

You need to add one attribute onrowcommand="MyGridView_RowCommand" inside GridView MarkUp.

And define the Event in Code Behind as follows.

void MyGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
    if(e.CommandName=="SELECT")
    {
        // Do whatever you want to do.
    }
}

参考上面给出的MSDN链接了解更多并查看实现。

这是我的标记

here is my markup

<asp:gridview id="GridView1" runat="server" allowpaging="True" xmlns:asp="#unknown">
                     AutoGenerateColumns="False" DataKeyNames="op" DataSourceID="SqlDataSource1"

                     style="z-index: 1; left: 276px;font-size:24px; top: 321px; position: absolute; height: 131px; width: 717px"
                     ForeColor="White" onrowcommand="GridView1_RowCommand">
                     <columns>
                         <asp:boundfield datafield="diarycontent" headertext="diarycontent">
                             SortExpression="diarycontent" />
                         <asp:boundfield datafield="diarypass" headertext="diarypass">
                             SortExpression="diarypass" />
                         <asp:boundfield datafield="diarydate" headertext="diarydate">
                             SortExpression="diarydate" />
                         <asp:boundfield datafield="opp" headertext="page number" sortexpression="opp" />
                         <asp:buttonfield buttontype="Button" commandname="Select">
                             HeaderText="view diary page" ShowHeader="True" Text="View Diary Page" />
                     </asp:buttonfield></asp:boundfield></asp:boundfield></asp:boundfield></columns>
                 </asp:gridview>

和cs代码

and cs code

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
   {

       if (e.CommandName == "SELECT")
       {

           MessageBox.Show("hello");
       }
   }

及其无效。:(
