如何在gridview中创建一个按钮会导致部分回发并更新我的面板 [英] How to make a button inside a gridview cause a partial post back and update my panel

问题描述

我有一个带有gridview的更新面板。 gridview包含一个按钮列。我希望每次单击此按钮时，都应刷新更新面板。从我能够实现的，buttton工作正常但我只能看到效果当我再次刷新整个页面。我需要在不刷新页面的情况下看到对click事件的影响。如何使这个gridview按钮导致部分回发



我尝试过：

i have an update panel with a gridview. The gridview consists of a button column. I want everytime this button is clicked, the update panel should be refreshed. From what i have been able to achieve, the buttton works fine but i would only be able to see the effect when i refreshed the whole page again. I need to see the effect on the click event without refreshing the page. How do i make this gridview button cause partial postback

What I have tried:

<pre lang="ASP.NET"><asp:TemplateField HeaderText="Action" Visible="True">
                               <ItemTemplate>
                                   <asp:Button Visible='<%# string.IsNullOrEmpty(Eval("Signout_Time").ToString()) %>' ID="out" runat="server" Text="Sign out" CommandName="SignOut"  CommandArgument='<%#Eval("SN") %>' ClientIDMode="AutoID"/>
                               </ItemTemplate>
                           </asp:TemplateField>

这是背后的代码。

This is the code behind.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
       {
           if (e.Row.RowType == DataControlRowType.DataRow)
           {
               Button lb = e.Row.FindControl("out") as Button;
               ScriptManager.GetCurrent(this).RegisterAsyncPostBackControl(lb);
           }
    }

这就是我点击按钮时的作用

this is what the button does when i click

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
       {
          if (e.CommandName == "SignOut")
           {
               string sN = e.CommandArgument.ToString();
               reg.sn = int.Parse(sN);
           string sign = System.DateTime.Now.ToString("yyyy-MM-dd:HH:mm:ss"); // get time out time
           reg.signout = sign;
           reg.SignOut(); // Save the signout time in db

整个过程结束后，我希望按钮只更新updatepanel。

After the whole process, i want the button to update only the updatepanel.

请参考
