如何捕获在datagrid模版列中dropdownList控件的selectindexchange事件。

[mihi1978]

用addhandler好像不行。

绑定时,添加委托,

[mihi1978]

Private Sub dgCommunion_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgCommunion.EditCommand
Dim selectValue As Int32 = Int32.Parse(dgCommunion.Items(e.Item.ItemIndex).Cells(2).Text)
dgCommunion.EditItemIndex = e.Item.ItemIndex
BindData()
Dim txt As TextBox
drop = dgCommunion.Items(e.Item.ItemIndex).Cells(4).FindControl("DropDownList1")
txt = dgCommunion.Items(e.Item.ItemIndex).Cells(5).FindControl("TextBox1")
Dim sourceRead As New Sources
drop.DataSource = sourceRead.LoadSource()
drop.DataTextField = "数据来源名称"
drop.DataValueField = "数据来源编号"
drop.DataBind()
drop.SelectedValue = selectValue

If drop.SelectedValue = 1 Then
txt.Enabled = True
End If
AddHandler drop.SelectedIndexChanged, AddressOf DropSelectedChanged

End Sub
上面是我在EditCommand中的代码。我也是在绑定后，用了AddHandler drop.SelectedIndexChanged, AddressOf DropSelectedChanged好像不行。没有响应DropSelectedChanged方法

把AutoPostBack设为true
前台：
<ItemTemplate>
<asp:DropDownList runat="server" id="ddl" AutoPostBack="true" OnSelectedIndexChanged="ddl_SelectedIndexChanged">
<asp:ListItem>Item 1</asp:ListItem>
<asp:ListItem>Item 2</asp:ListItem>
<asp:ListItem>Item 3</asp:ListItem>
</asp:DropDownList>

在cs文件中
public void ddl_SelectedIndexChanged(Object sender, EventArgs e)
{
}

其实你也可以这么做:在html页，找到DorpDownList的代码出，给它添加：
selectedIndexChanged="DDLChanged"
然后你再.vb/.cs里面编写DDLChanged即可

同意岁寒一友acewang(**^o^**) 的做法

[guoyan19811021]

同意： acewang(**^o^**) 的方法
在html中OnSelectedIndexChanged="ddl_SelectedIndexChanged"
在.cs后台文件中：

public void ddl_SelectedIndexChanged(Object sender, EventArgs e)
{
}

我也遇到过类似的情况，用上述方法可以，但怎样获得DataGrid中触发事件的items呢？既这个东西System.Web.UI.WebControls.DataGridItemEventArgs e
