無法獲取數據網格中的複選框值ASP.NET

Question

我有一個DataGrid，它具有用於選擇特定用戶的複選框。點擊Ok按鈕後，我應該得到複選框的狀態，如果選中，則獲取該行的ID。我到達複選框，但值總是Checked = false，當然，即使當我檢查我的複選框。代碼如下：

的.aspx

 <Columns> 

      <asp:TemplateColumn HeaderText="Odabir"> 
       <ItemTemplate> 
        <asp:CheckBox ID="chkVjezba" runat="server" Enabled="true"/> 
       </ItemTemplate> 
      </asp:TemplateColumn> 

      <asp:BoundColumn HeaderText="Vježba" DataField="Naziv"></asp:BoundColumn> 

      <asp:TemplateColumn HeaderText="Broj serija"> 
       <ItemTemplate> 
        <asp:TextBox ID="brojSerija" runat="server" Width="20px"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateColumn> 

      <asp:TemplateColumn HeaderText="Ocjena 6"> 
       <ItemTemplate> 
        <asp:TextBox ID="ocjena6" runat="server" Width="20px"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateColumn> 

      <asp:TemplateColumn HeaderText="Ocjena 7"> 
       <ItemTemplate> 
        <asp:TextBox ID="ocjena7" runat="server" Width="20px"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateColumn> 

      <asp:TemplateColumn HeaderText="Ocjena 8"> 
       <ItemTemplate> 
        <asp:TextBox ID="ocjena8" runat="server" Width="20px"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateColumn> 

      <asp:TemplateColumn HeaderText="Ocjena 9"> 
       <ItemTemplate> 
        <asp:TextBox ID="ocjena9" runat="server" Width="20px"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateColumn> 

      <asp:TemplateColumn HeaderText="Ocjena 10"> 
       <ItemTemplate> 
        <asp:TextBox ID="ocjena10" runat="server" Width="20px"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateColumn> 
     </Columns> 

    </asp:DataGrid> 

我的.cs代碼文件：

foreach (DataGridItem row in vjezbeGrid.Items) 
      { 
      if (((CheckBox)row.Cells[0].FindControl("chkVjezba")).Checked) 
      { 
       //something 
      } 

     } 

感謝。

Answer 1

你可能會在每次回傳數據綁定。確保你的數據綁定只有在！Page.IsPostBack。

Answer 2

嘗試這樣

foreach (DataGridItem row in vjezbeGrid.Items) 
     { 
      if (row.ItemType == ListItemType.Item) 
      { 
       CheckBox chkVjezba = (CheckBox)row.FindControl("chkVjezba"); 

       if (chkVjezba.Checked) 
       { 
        //something 
       } 
      } 

     }
