你如何绑定在EditItemTemplate里场一个GridView一个DropDownList？ [英] How do you bind a DropDownList in a GridView in the EditItemTemplate Field?

问题描述

下面是在运行时绑定的GridView我的code：

Here's my code in a gridview that is bound at runtime:

...
<asp:templatefield>
    <edititemtemplate>
        <asp:dropdownlist runat="server" id="ddgvOpp" />
    </edititemtemplate>
    <itemtemplate>
        <%# Eval("opponent.name") %>
    </itemtemplate>
</asp:templatefield>
...

我要DropDownList的ddgvOpp绑定，但我不知道怎么办。我应该，但我不知道。下面是我的，但我不断收到对象引用的错误，这是有道理的：

I want to bind the dropdownlist "ddgvOpp" but i don't know how. I should, but I don't. Here's what I have, but I keep getting an "Object reference" error, which makes sense:

protected void gvResults_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow) //skip header row
    {
        DropDownList ddOpp = (DropDownList)e.Row.Cells[5].FindControl("ddgvOpp");
        BindOpponentDD(ddOpp);
    }
}

其中， BindOpponentDD（）是DropDownList的被填充流向何方。我不能这样做在右边的事件吗？如果没有，这我需要把它吗？

Where BindOpponentDD() is just where the DropDownList gets populated. Am I not doing this in the right event? If not, which do I need to put it in?

在此先感谢这么多...

Thanks so much in advance...

推荐答案

好吧，我想我只是哑巴。我想它了。

Ok, I guess I'm just dumb. I figured it out.

在RowDataBound事件，只需添加以下条件：

In the RowDataBound event, simply add the following conditional:

if (myGridView.EditIndex == e.Row.RowIndex)
{
     //do work
}
