网格视图触发了未处理的事件行编辑。 [英] The grid view fired event row editing which wasn't handled.

问题描述

我有gridview如下



ID名称季节行动



14756 Test1 2018编辑删除

22089 Test2 2018编辑删除

33571 Test3 2018编辑删除

17912 Test4 2018编辑删除





当我点击第一行中的编辑链接按钮时，它将重定向到farmermasterpage但是当我点击第三行中的编辑链接按钮时，它不会重定向到farmermasterpage。





编辑代码如下

 if（e.CommandName ==Edit）
 {
 Response.Redirect（〜/ ivorycoast / farmermaster.aspx？action = edit& farmercode =+ e.CommandArgument .ToString（），false）; 
} 
 
 Gridview源.aspx页面代码如下
 
 <   asp：TemplateField     HeaderText   = 操作 >  
 <   itemtemplate  >  
 <   asp：LinkBut​​ton     ID   =  lnkEdit    runat   =  server < span class =code-attribute>  工具提示  = 点击编辑    CommandArgument   ='  <％ #DataBinder.Eval（Container.DataItem，  farmerctscode）％>'    CommandName   = 编辑    OnCommand   =  onCommand >  
 | 
 <   asp：LinkBut​​ton     ID   =  lnkDelete    runat   = 服务器   工具提示  =  点击编辑    CommandArgument   ='  <％＃DataBinder.Eval（Container .DataItem，  farmerctscode）％>'    CommandName   = 删除    OnCommand   =  onCommand >  

当我运行上面的代码时显示错误如下



GridView'grdFarmerList'触发了未处理的事件RowEditing。



注意：对于response.redirect，我添加了false。



Response.Redirect（〜/ ivorycoast / farmermaster.aspx？action = edit& farmercode =+ e.CommandArgument。 ToString（），false）;



上面代码中的错误是什么。

解决方案

因为命令名是Edit，所以gridView期望调用RowEditing事件。

定义该事件并将所需代码放在那里。

MSDN上的一个小搜索非常清楚： GridView.RowCommand Event（System.Web.UI.WebControls） [< a href =https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.rowcommand(v=vs.110).aspx\"target =_ blanktitle =New窗口> ^ ]

I have gridview as follows

ID Name Season Actions

14756 Test1 2018 Edit Delete
22089 Test2 2018 Edit Delete
33571 Test3 2018 Edit Delete
17912 Test4 2018 Edit Delete


When i click the edit link button in the first row it will redirect to farmermasterpage but when i click edit link button in the third row it does not redirect to farmermasterpage.


Edit code as follows

if (e.CommandName == "Edit")
{
Response.Redirect("~/ivorycoast/farmermaster.aspx?action=edit&farmercode=" + e.CommandArgument.ToString() ,false);
}
 
Gridview source .aspx page code as follows
 
<asp:TemplateField HeaderText="Actions">
<itemtemplate>
<asp:LinkButton ID="lnkEdit" runat="server" ToolTip="Click to edit" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "farmerctscode") %>' CommandName="Edit" OnCommand="onCommand">
| 
<asp:LinkButton ID="lnkDelete" runat="server" ToolTip="Click to edit" CommandArgument='<%# DataBinder.Eval(Container.DataItem, "farmerctscode") %>' CommandName="Delete" OnCommand="onCommand">

when i run the above code shows error as follows

The GridView 'grdFarmerList' fired event RowEditing which wasn't handled.

Note : for response.redirect i added false.

Response.Redirect("~/ivorycoast/farmermaster.aspx?action=edit&farmercode=" + e.CommandArgument.ToString() ,false);

what is the mistake in my above code.

What I have tried:

解决方案

Because the commandname is Edit the gridView expects to call the RowEditing event.
Define that Event and put the code you need there.
A small search on MSDN is pretty clear about that: GridView.RowCommand Event (System.Web.UI.WebControls)[^]
