我有一个填充一些事务的 ASPxGridView。

<dx:ASPxGridView ID="grdCapTrans" runat="server" ClientIDMode="AutoID" Width="100%"   EnableRowsCache="false">
</dx:ASPxGridView>

当它填充时，我想让用户自由选择一行并查看单击行的详细信息。详细信息应显示在文本框中的网格视图下方。

如何在服务器上触发和处理？

您可以使用RowCommand event

<dx:ASPxGridView ID="grid" 
runat="server" 
ClientInstanceName="grid" 
AutoGenerateColumns="false" 
onrowcommand="grid_RowCommand" >
   <Columns>
     <dx:GridViewCommandColumn ShowSelectCheckbox="true" VisibleIndex="0" ButtonType="Button" />
   </Columns>
 </dx:ASPxGridView>

代码背后：

 protected void grid_RowCommand(object sender, ASPxGridViewRowCommandEventArgs e)
 {
    ..... 
 }

绑定您的数据

grid.DataSource = ...;
grid.DataBind();

        </dx:ASPxGridView>

        </p>
    </ContentTemplate>
    </asp:UpdatePanel>

代码背后

protected void grdCapTrans_SelectionChanged(object sender, EventArgs e)

{ 

    UpdatePanel1.Update();
    txtFullName.Text = grdCapTrans.GetSelectedFieldValues("Description")[1].ToString();

    message.InnerHtml = "Happy";


}

消息元素是一个 div，可在 updatepanel1 中找到。如果 selectionChanged 事件触发，我希望显示消息“Happy”。令我惊讶的是，它没有。

出了什么问题，如何纠正。
