ASP.NET 网格视图下拉列表模板字段触发选定索引在网格视图上更改

本文关键字：视图 网格 索引 下拉列表 NET ASP 字段 | 更新日期: 2023-09-27 18:37:01

我有一个基本的 ASP.NET 网格视图，带有一个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>

它填充在行数据绑定

   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

我希望下拉列表触发 GridView1 selectedindexchanged 事件，以便我可以获取所选行的 ProjectID，但我也想获取下拉列表 ddlAction 的选定值

与此示例类似谢谢

更新了答案

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)

我已经有

一段时间没有使用 vb 了，但是您在事件方法中无法访问发件人吗？ 

var value = (sender as DropDownList).SelectedValue;
