ASP .Net如何识别GridView中的删除按钮？

Question

我有一个GridView与ItemTemplate按钮，使用RowCommand函数来执行SQL。请注意，其中一个命令名称为“delete”来评估哪个按钮被按下。这是否会导致GridView触发RowDeleting事件？我认为ASP .Net认为我创建了一个自定义的删除按钮，因此触发了该事件。我不使用这个事件，并且它试图激发它，因为它不存在。有没有办法禁用？

的GridView

 <asp:GridView ID="gv_uebersicht" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="Solid" BorderWidth="1px" CellPadding="3" ForeColor="Black" GridLines="Vertical" OnRowCommand="gv_uebersicht_RowCommand" OnRowDataBound="gv_uebersicht_RowDataBound" OnRowDeleting="gv_uebersicht_RowDeleting"> 
      <AlternatingRowStyle BackColor="#CCCCCC" /> 
      <Columns> 
       <asp:BoundField DataField="cockpit_id" HeaderText="cockpitid" /> 
       <asp:BoundField DataField="lieferant" HeaderText="Lieferant" /> 
       <asp:BoundField DataField="datei" HeaderText="Dateiname" /> 
       <asp:BoundField DataField="status" HeaderText="Status" /> 
       <asp:BoundField DataField="erstellzeit" HeaderText="Erstellzeit" /> 
       <asp:BoundField DataField="meldung" HeaderText="Meldung" /> 
       <asp:TemplateField HeaderText="Aktion"> 
        <ItemTemplate> 
         <asp:Button ID="btn_delete" runat="server" CommandArgument='<%# Eval("cockpit_id") %>' CommandName='<%# "delete" %>' Text="Löschen" Visible='<%# Eval("status_id").ToString() == "2" || Eval("status_id").ToString() == "14" || Eval("status_id").ToString() == "67" || Eval("status_id").ToString() == "68" || Eval("status_id").ToString() == "999" || Eval("status_id").ToString() == "1" || Eval("status_id").ToString() == "69" %>' /> 
         <asp:Button ID="btn_move" runat="server" CommandArgument='<%# Eval("cockpit_id") %>' CommandName='<%# "move" %>' Text="Move" Visible='<%# Eval("status_id").ToString() == "2" || Eval("status_id").ToString() == "14" || Eval("status_id").ToString() == "67" %>' /> 
        </ItemTemplate> 
       </asp:TemplateField> 
       <asp:BoundField DataField="status_id" HeaderText="statusid" /> 
      </Columns> 
      <FooterStyle BackColor="#CCCCCC" /> 
      <HeaderStyle BackColor="Black" Font-Bold="True" ForeColor="White" /> 
      <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" /> 
      <SelectedRowStyle BackColor="#000099" Font-Bold="True" ForeColor="White" /> 
      <SortedAscendingCellStyle BackColor="#F1F1F1" /> 
      <SortedAscendingHeaderStyle BackColor="#808080" /> 
      <SortedDescendingCellStyle BackColor="#CAC9C9" /> 
      <SortedDescendingHeaderStyle BackColor="#383838" /> 
     </asp:GridView> 

RowCommand功能

protected void gv_uebersicht_RowCommand(object sender, GridViewCommandEventArgs e) 
    { 
     string commandName = e.CommandName; 
     string commandArgument = e.CommandArgument.ToString(); 

     lbl_msg.Text = "Die Datei " + DatabaseFunctions.GetScalar("SELECT VDB_LS_DATEI FROM VDB_LADESTATUS_COCKPIT WHERE VDB_LS_ID = " + commandArgument) + " wird " + (commandName == "move" ? "gemoved." : "gelöscht."); 

     ds.UpdateCommand = @"UPDATE VDB_LADESTATUS_COCKPIT 
          SET VDB_LS_STATUS_ID = 19 
          WHERE VDB_LS_ID = " + commandArgument; 
     ds.Update(); 
     ds.InsertCommand = @"DECLARE 
           V_RC INTEGER; 
          BEGIN 
           V_RC := Val.Loeschen_Freigabe_Funktionen(P_Cockpit_ID => " + commandArgument + @", 
                     P_Aktion => '" + commandName + @"'); 
          END; "; 
     ds.Insert(); 
     fill_gv_uebersicht(); 
    }

是的，GridView触发RowDeleting事件，因为按钮的CommandName是删除。您必须更改CommandName，并且必须从GridView控件中删除OnRowDeleting="gv_uebersicht_RowDeleting"。它不会抛出任何错误。
