Question

我正在尝试使用带有按钮的GetSelectedFieldValues方法从ASPxGridView中的所选行中获取一个值这么简单。

我已经按照DevExpress文档中的步骤进行了操作，我想要检索Label中的值。使用经典的ASPGridView没什么困难。

Protected Sub ASPxButton1_Click(sender As Object, e As EventArgs) Handles ASPxButton1.Click
    Dim oRowVal As List(Of Object)
    Dim oVal As Object
    oRowVal = ASPxGridView1.GetSelectedFieldValues({"No_"})
    oVal = oRowVal(0)
    Label1.Text = oVal.ToString
End Sub

正如您所看到的，我想要的是在ASPxGridView中获取所选值并将其显示在Label中。

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
<br />
<dx:ASPxButton ID="ASPxButton1" runat="server" AutoPostBack="False" Text="ASPxButton" Theme="BlackGlass" Width="150px">
</dx:ASPxButton>
<dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" EnableTheming="True" Theme="BlackGlass">
    <Columns>
        <dx:GridViewCommandColumn ShowSelectCheckbox="True" VisibleIndex="0">
            <ClearFilterButton Visible="True">
            </ClearFilterButton>
        </dx:GridViewCommandColumn>
        <dx:GridViewDataTextColumn Caption="GP" FieldName="No_" VisibleIndex="1">
        </dx:GridViewDataTextColumn>
        <dx:GridViewDataTextColumn Caption="Description" FieldName="Descripción Grupo" VisibleIndex="2">
        </dx:GridViewDataTextColumn>
    </Columns>
    <SettingsBehavior AllowSelectSingleRowOnly="True" />
    <Settings ShowFilterRow="True" ShowGroupPanel="True" />
</dx:ASPxGridView>

提前致谢!!!

Answer 1

指定 ASPxGridView.KeyFieldName 属性以使用选择状态：

<dx:ASPxGridView ... KeyFieldName="...">

顺便提一下，以下代码是否会返回正确的结果？

oRowVal = ASPxGridView1.GetSelectedFieldValues({"No_"})
oVal = oRowVal(0)

ASPxGridView GetSelectedFieldValues不检索值
