显示消息框的命令字段 [英] Command field showing messagebox

问题描述

我有这样的命令字段，

 < asp：CommandField ShowEditButton =trueShowDeleteButton =True ItemStyle-Width =10px/> 
  

现在删除我想显示一个确认框，但不知道该怎么做。

抱歉，我不想使用Template字段。

也许某种程度上，我可以使用JS来显示消息，或者也可以在此代码的后面添加方法，

  protected void GridView1_RowDeleting（object sender，GridViewDeleteEventArgs e）
  

我试过了， / b>

  protected void GridView1_RowDataBound（object sender，GridViewRowEventArgs e）
 {
 if（e.Row.RowType = = DataControlRowType.DataRow）
 {
 //在这个示例中，有3个按钮，第二个是Delete按钮，这就是为什么我们使用索引2 
 //索引变为0 （按钮）e.Row.Cells [0] .Controls [2]）。OnClientClick =按钮＃1，1文字（按钮之间的空间），2按钮＃2，3文字（空格） return confirm（''你确实要删除吗？'）;; 
} 
} 
  

但是我得到的索引超出了限制，因为那里没有任何控制。来源

以下是我的GridView的完整代码我更改了列和其他文本的名称，因此不要混淆，

解决方案

如果删除CommandField在您的网格视图的第二列

  protected void GridView1_RowDataBound（object sender，GridViewRowEventArgs e）
 {
 if（e.RowType == DataControlRowType.DataRow）
 {
 
 LinkBut​​ton link =（LinkBut​​ton）e.Row.Cells [4] .Controls [2]; 
 if（link！= null）
 {
 link.OnClientClick =return confirm（'你确实要删除吗？'）; 
} 
} 
} 
  

I have a command field like this,

<asp:CommandField ShowEditButton="true" ShowDeleteButton="True" ItemStyle-Width="10px" />

Now on delete I want to display a confirmation box but not sure how can I do it.

sorry but I don't want to use Template field.

Maybe somehow I can use JS to display message or maybe in this code behind method,

 protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)

I tried this,

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //In this sample, there are  3 buttons and the second one is Delete button, that's why we use the index 2
        //indexing goes as 0 is button #1, 1 Literal (Space between buttons), 2 button #2, 3 Literal (Space) etc.
        ((Button)e.Row.Cells[0].Controls[2]).OnClientClick = "return confirm('"Do you really want to delete?');";
    }
}

but I am getting index out of bound as there isn't any control there. SOURCE

Here's full code of my GridView I changed names of columns and other text so don't get confused,

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
        <asp:GridView ID="GridView1" runat="server" DataKeyNames="UserID" AutoGenerateColumns="false"

解决方案

if delete CommandField is on second column of your grid view

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {

        LinkButton link = (LinkButton)e.Row.Cells[4].Controls[2];
        if (link != null)
        {
            link.OnClientClick = "return confirm('Do you really want to delete?')";
        }
    }
}
