Gridview RowCommand가 작동하지 않습니다.

Question

gridview에서 발생시키는 rowcommand 이벤트를 가져 오는 데 문제가 있습니다. MSDNet의 코드 예제를 따랐지만 왜 작동하지 않는지 알 수는 없습니다. 코드는 다음과 같습니다. 고맙습니다.

<asp:GridView ID="GridViewProducts" runat="server" AutoGenerateColumns="False" 
    BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" 
    CellPadding="5" CellSpacing="1" DataKeyNames="Pkey" 
    DataSourceID="SqlDataSourceProducts" ForeColor="Black" GridLines="Vertical"> 
    <FooterStyle BackColor="#CCCCCC" /> 
    <PagerSettings PageButtonCount="20" /> 
    <Columns> 
     <asp:BoundField DataField="Product" HeaderText="Product" > 
      <HeaderStyle HorizontalAlign="Left" />

     </asp:BoundField> 
     <asp:TemplateField HeaderText="Interest"> 
      <ItemTemplate>

        <asp:ListItem></asp:ListItem> 
        <asp:ListItem>Low</asp:ListItem> 
        <asp:ListItem>Medium</asp:ListItem> 
        <asp:ListItem>High</asp:ListItem> 
        <asp:ListItem>None</asp:ListItem> 
       </asp:DropDownList> 
      </ItemTemplate> 
     </asp:TemplateField> 
     <asp:TemplateField HeaderText=""> 
      <ItemTemplate> 
       <asp:Button runat="server" ID="TestButton" Text="Button" CommandName="Test" 
       CommandArgument="<%# CType(Container, GridViewRow).RowIndex %>" /> 
      </ItemTemplate> 
      <HeaderStyle HorizontalAlign="center" /> 
      <ItemStyle HorizontalAlign="center" /> 
     </asp:TemplateField> 
    </Columns> 
    <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" /> 
    <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" /> 
    <HeaderStyle BackColor="Silver" Font-Bold="True" ForeColor="Black" /> 
    <AlternatingRowStyle BackColor="#CCCCCC" /> 
</asp:GridView>

귀하의 gridview는 이벤트에 마크 업을 사용하지 않습니다.

<asp:GridView ID="GridViewProducts" runat="server" AutoGenerateColumns="False" 
BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" 
CellPadding="5" CellSpacing="1" DataKeyNames="Pkey" 
DataSourceID="SqlDataSourceProducts" ForeColor="Black" GridLines="Vertical" 
onrowcommand="GridViewProducts_RowCommand"> 

Answer 2

@rtpHarry이 올바른지, 그 이벤트를 연결할 수있는 유효한 방법입니다 onrowcommand="GridViewProducts_RowCommand"에 추가

시도는 그래서는 다음과 같습니다. 이벤트를 배선의 또 다른 방법은 뒤에 끝에 Handles Me.GridViewProducts.RowCommand를 추가하는 코드에서 메소드의 서명을 변경하는 것입니다 :

Sub GridViewProducts_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs) Handles Me.GridViewProducts.RowCommand
