更新按钮触发编辑事件处理程序 [英] Update button fires edit event handler

问题描述

我有一个gridview。标记就是这样...

 < asp：GridView ID =gvwServersrunat =serverclass =gvwServers 
 AutoGenerateColumns =falseOnRowEditing =gvwServers_Edit
 onrowcancelingedit =gvwServers_Cancellingonrowdeleting =gvwServers_Deleting
 onrowupdated =gvwServers_Updatedonrowupdating =gvwServers_Updating
 AutoGenerateEditButton = true AutoGenerateDeleteButton =真> 
 
< columns> 
< asp：CommandField ButtonType =ButtonEditText =EditShowEditButton =true/> 
< asp：CommandField ButtonType =ButtonEditText =DeleteShowDeleteButton =true/> 
 
 ...绑定字段和模板字段等... 
  

我的代码隐藏有这个...

  protected void gvwServers_Edit（object sender，GridViewEditEventArgs e）
 {
 gvwServers.EditIndex = e.NewEditIndex; 
 gvwServers.DataBind（）; 
} 
 protected void gvwServers_Updated（object sender，GridViewUpdatedEventArgs e）
 {
 gvwServers.DataBind（）; 
} 
 
 protected void gvwServers_Updating（object sender，GridViewUpdateEventArgs e）
 {
 gvwServers.DataBind（）; 
} 
 protected void gvwServers_Deleting（object sender，GridViewDeleteEventArgs e）
 {
 gvwServers.DataBind（）; 
} 
 protected void gvwServers_Cancelling（object sender，GridViewCancelEditEventArgs e）
 {
 e.Cancel = true; 
 gvwServers.EditIndex = -1; 
 gvwServers.DataBind（）; 
} 
  

事情是大多数这些例程正常启动，即编辑，删除，取消。 除了，当我点击更新按钮， gvwServers_Edit（）触发。为什么会这样呢？如何使更新按钮点击fire gvwServers_Updating（）？

更新：我的问题已解决这里。

解决方案

您可以随时将事件重新映射到函数..

几乎...编辑事件只能映射到具有（object sender，GridViewCancelEditEventArgs e）作为参数的函数，同样更新函数必须有（对象发件人，GridViewUpdatedEventArgs e） params ...

您可以使用预制的事件处理函数或自己做，再一次的关键是'e'参数类型。

如果要对Edit（）和Updating（）事件都具有通用功能，请将该代码放入单独的函数中，这些函数在处理程序发生时被调用火。

I have a gridview. Markup is like this...

<asp:GridView ID="gvwServers" runat="server" class="gvwServers"  
AutoGenerateColumns="false"  OnRowEditing="gvwServers_Edit" 
onrowcancelingedit="gvwServers_Cancelling" onrowdeleting="gvwServers_Deleting" 
onrowupdated="gvwServers_Updated" onrowupdating="gvwServers_Updating"
AutoGenerateEditButton=true AutoGenerateDeleteButton=true>

  <columns>
    <asp:CommandField ButtonType="Button" EditText="Edit" ShowEditButton="true" />
    <asp:CommandField ButtonType="Button" EditText="Delete" ShowDeleteButton="true" />

    ...Bound fields and template fields etc...

My Code-behind has this...

protected void gvwServers_Edit(object sender, GridViewEditEventArgs e)
{
    gvwServers.EditIndex = e.NewEditIndex;
    gvwServers.DataBind();
}
protected void gvwServers_Updated(object sender, GridViewUpdatedEventArgs e)
{
    gvwServers.DataBind();
}

protected void gvwServers_Updating(object sender, GridViewUpdateEventArgs e)
{
    gvwServers.DataBind();
}
protected void gvwServers_Deleting(object sender, GridViewDeleteEventArgs e)
{
    gvwServers.DataBind();
}
protected void gvwServers_Cancelling(object sender, GridViewCancelEditEventArgs e)
{
    e.Cancel = true;
    gvwServers.EditIndex = -1;
    gvwServers.DataBind();
}

The thing is that most of these routines fire correctly ie Edit, Delete, Cancel. Except when I click the Update button, gvwServers_Edit() fires. Why is this happening? How do I make the Update button click fire gvwServers_Updating()?

Update: My issue is resolved here.

解决方案

You can always re-map the event to the function..

Well almost...the "Edit" events can only map to a function that has (object sender, GridViewCancelEditEventArgs e) as params, likewise update functions must have (object sender, GridViewUpdatedEventArgs e) params...

You can use the pre-made event handling function or make your own, again the key being the 'e' param type.

If you want to have common functionality for both the Edit() and Updating() event, put that code into a separate function that is called by the handlers when those events fire.
