隱藏的LinkBut​​ton在asp.net GridView控件

Question

所以我有一個按鈕，如下的畫面：

所以，當我按這個鏈接按鈕（位於模板域內電網控制的） ，我想隱藏它並顯示一個組合框，而不是用戶可以在其中獲取狀態的組合框。

我已經創建了下面的代碼：

if (e.CommandName == "IzmjeniStatus") 
       { 
        string[] arg = e.CommandArgument.ToString().Split(';'); 
        int index = Convert.ToInt32(arg[1].ToString()); 
// first locating the combo box inside of template field 
        DropDownList ComboStatus = (DropDownList)gridKorisnici.Rows[index].FindControl("DropDownList1"); 
// then locating the button 
        LinkButton btnIzmjeniStatus = (LinkButton)gridKorisnici.Rows[index].FindControl("btnStatusKorusnika"); 
        btnIzmjeniStatus.Visible = false; 
        ComboStatus.Visible = true; 
// once the button is pressed, hide the button and show the dropdown list 

        int KupacID = Convert.ToInt32(arg[0].ToString()); 
        hsp_Kupci_SelectByID_Result k = ServisnaKlasa.KupacByID(KupacID); 
        if(k.Status==true) 
        { 
         ServisnaKlasa.UpdateStatusKorisnika(KupacID, false); 
        } 
        else 
        { 
         ServisnaKlasa.UpdateStatusKorisnika(KupacID, true); 
        } 
        BindGrid(); 
       } 

這是網格的ASPX代碼：

<asp:GridView ID="gridKorisnici" AutoGenerateColumns="false" AllowPaging="true" PageSize="20" runat="server" OnRowCommand="gridKorisnici_RowCommand" OnRowDataBound="gridKorisnici_RowDataBound" OnPageIndexChanging="gridKorisnici_PageIndexChanging"> 
     <Columns> 
      <asp:BoundField DataField="Ime" HeaderText="Ime"/> 
      <asp:BoundField DataField="Prezime" HeaderText="Prezime" /> 
      <asp:BoundField DataField="Email" HeaderText="Email"/> 
      <asp:CheckBoxField DataField="Popust" HeaderText="Popust"/> 
      <asp:BoundField DataField="IznosPopusta" HeaderText="Iznos popusta(%)"/> 
      <asp:CheckBoxField DataField="Status" HeaderText="Aktivan"/> 
      <asp:TemplateField HeaderText="Unos popusta(%)"> 
       <ItemTemplate> 
        <asp:TextBox ID="txtPopust2" runat="server"></asp:TextBox> 
       </ItemTemplate> 
      </asp:TemplateField> 
      <asp:TemplateField> 
       <ItemTemplate> 
        <asp:LinkButton ID="btnPopust" runat="server" Title="Aktivacija popusta" CommandName="AktivirajPopust" CommandArgument='<%#Eval("KupacID") + ";" +((GridViewRow) Container).RowIndex%>' ><img src="../images/1popust.png" /></asp:LinkButton> 
       </ItemTemplate> 
      </asp:TemplateField> 
       <asp:TemplateField> 
       <ItemTemplate> 
        <asp:LinkButton ID="btnDeaktivirajPopust" Title="Deaktivacija popusta" runat="server" CommandName="DeaktivirajPopust" CommandArgument='<%# Eval("KupacID") %>'><img src="../images/1popustminus.png" /></asp:LinkButton> 
       </ItemTemplate> 
      </asp:TemplateField> 
       <asp:TemplateField> 
       <ItemTemplate> 
        <asp:LinkButton ID="btnStatusKorusnika" title="Izmjeni status" runat="server" CommandName="IzmjeniStatus" CommandArgument='<%#Eval("KupacID") + ";" +((GridViewRow) Container).RowIndex%>'><img src="../images/1status.png" /></asp:LinkButton> 
        <asp:DropDownList ID="DropDownList1" Visible="false" runat="server"></asp:DropDownList> 
       </ItemTemplate> 
      </asp:TemplateField> 
       <asp:TemplateField> 
       <ItemTemplate> 
        <asp:LinkButton ID="btnHistorijaPristupa" title="Historija pristupa" runat="server" CommandName="HistorijaPristupaCommand" CommandArgument='<%# Eval("KupacID") %>'><img src="../images/1logovi.png" /></asp:LinkButton> 
       </ItemTemplate> 
      </asp:TemplateField> 
     </Columns> 
    </asp:GridView> 

我在做什麼錯在這裏，有人可以幫助我嗎？ ？

謝謝。

如果我沒有錯誤的方法BindGrid（）是這裏的問題，它會將gridview帶到初始狀態，您已經將組合框的可見屬性設置爲'false'，嘗試刪除BindGrid（）並檢查如果你能看到組合框。
