Question

我有一个基本的ASP.NET Gridview w / a ddlAction下拉列表

    <asp:GridView ID="GridView1" CssClass="mgrid2"
    runat="server" AutoGenerateColumns="False" ForeColor="White" DataSourceID="SqlDataSource1" OnRowCommand="GridView1_RowCommand" OnRowDataBound="GridView1_RowDataBound">
    <Columns>
        <asp:BoundField DataField="ClientName" HeaderText="ClientName" SortExpression="ClientName" />
        <asp:BoundField DataField="ProjectID" HeaderText="ProjectID" SortExpression="ProjectID" />
        <asp:BoundField DataField="ProjectName" HeaderText="ProjectName" SortExpression="ProjectName" />
        <asp:BoundField DataField="Budget" HeaderText="Budget" ReadOnly="True" SortExpression="Budget" />
        <asp:BoundField DataField="PercentComplete" HeaderText="PercentComplete" ReadOnly="True" SortExpression="PercentComplete" />
        <asp:BoundField DataField="EarnedMH" HeaderText="EarnedMH" ReadOnly="True" SortExpression="EarnedMH" />
        <asp:TemplateField>
            <ItemTemplate>
                <asp:DropDownList ID="ddlAction" CssClass="dropdownlist" runat="server" AutoPostBack="true" OnSelectedIndexChanged=""GridView1_SelectedIndexChanged"></asp:DropDownList>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

它填充在rowdatabound

上

   If e.Row.RowType = DataControlRowType.DataRow Then
        Dim ddl = TryCast(e.Row.FindControl("ddlAction"), DropDownList)
        If ddl IsNot Nothing Then
            ddl.DataSource = New List(Of String)() From {
                "Action",
                "View",
                "Edit",
                "Archive"
            }
            ddl.DataBind()
   End IF

我想让dropdownlist触发GridView1 selectedindexchanged事件，这样我就可以获得所选行的ProjectID，但我还想得到下拉列表中选定的值ddlAction

Similar to this example 谢谢

更新w / Answer

Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridView1.SelectedIndexChanged
    Dim ddl = DirectCast(sender, DropDownList)
    Dim row As GridViewRow = CType(ddl.NamingContainer, GridViewRow)

通过这两项，您可以访问所需内容

我暂时没有使用vb，但是你没有在事件方法中访问发件人？

var value = (sender as DropDownList).SelectedValue;

ASP.NET Gridview下拉模板字段触发Gridview上的SelectedIndexChanged
