ASPxGridView GetSelectedFieldValues不检索值 [英] ASPxGridView GetSelectedFieldValues not retrieving values

问题描述

大家好！



我正在尝试从ASPxGridView控件中获取唯一一个选定值（单选按钮），并按照DevExpress上的文档中的步骤操作。



我唯一想要的是通过button_click检索一个字段并显示到标签中



这里是代码...

 受保护  Sub  ASPxButton1_Click（发件人作为 对象，e  As  EventArgs）句柄 ASPxButton1.Click 
  Dim  oRowVal 作为列表（  对象）
  Dim  oVal 作为 对象 
 oRowVal = ASPxGridView1.GetSelectedFieldValues（{  No _}）
 oVal = oRowVal（ 0 ）
 Label1.Text = oVal.ToString 
 结束  Sub  

这是控件的ASP代码...

 <   asp：Label     ID   =  Label1     runat   = < span class =code-keyword> server   文本  = 标签 >  <   / asp：标签 >  
 <   br     /  >  
 <   dx：ASPxButton     ID   =  ASPxButton1      runat   = 服务器    AutoPostBack   =  False   文字  =  ASPxButton   主题  =  BlackGlass   宽度  =  150px >  
 <   / dx：ASPxButton  >  
 <   dx：ASPxGridView     ID   =  ASPxGridView1      runat   =  server    AutoGenerateColumns   = 错误    DataSourceID   =  SqlDataSource1    EnableTheming   =  True   主题  =  BlackGlass >  
 <  列 >  
 <  < span class =code-leadattribute> dx：GridViewCommandColumn     ShowSelectCheckbox   =  True    VisibleIndex   =   0 >  
 <   ClearFilterButton    可见  =  True >  
 <   / ClearFilterButton  >  
 <   / dx：GridViewCommandColumn  > ;  
 <   dx：GridViewDataTextColumn    标题  =  GP    FieldName   =  No_     VisibleIndex   =  1 >  
 <   / dx：GridViewDataTextColumn  >  
  <   dx：GridViewDataTextColumn     Caption   = 描述    FieldName   = DescripciónGrupo    VisibleIndex   =  2 >  
 <   / dx：GridViewDataTextColumn  >  
 <   / Columns  >  
 <   SettingsBehavior     AllowSelectSingleRowOnly   = 真 <跨度class =code-attribute>   /  >  
 <  设置    ShowFilterRow   =  True    ShowGroupPanel   =  True    /  >  
 < span class =code-keyword><   / dx：ASPxGridView  >  

非常感谢提前!!!

解决方案

 Dim fieldNames As  String （）= New 字符串（）{ < column name =  >， 列名>} 
 Dim columnValues As  Object  = grdMemberslist.GetRowValues（grdMemberslist.FocusedRowIndex，fieldNames）< /  列 >  

将FocusIndex属性设为true。

Hi all!

I'm trying to get the only one selected value (radio button) from an ASPxGridView control and followed the steps from the documentation on DevExpress.

The only thing I want is to retrieve one field and display into a label via button_click

Here goes the code...

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

And this is the ASP code for the controls...

<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>

Many thanks in advance!!!

解决方案

Dim fieldNames As String() = New String() {"<column name="">", "Column name>"}
               Dim columnValues As Object = grdMemberslist.GetRowValues(grdMemberslist.FocusedRowIndex, fieldNames)</column>

Put FocusIndex property true in HTML.
