RowUpdating在EditItemTemplate中未觸發

Question

我將數組綁定到GridView。以下是我的模板字段，當點擊更新時它不會觸發RowUpdating。

<asp:TemplateField HeaderText="Role"> 
       <EditItemTemplate> 
        <asp:TextBox runat="server" Text='<%# Container.DataItem.ToString() %>' ID="txtEditRole"></asp:TextBox> 
       </EditItemTemplate> 
       <ItemTemplate> 
        <%# Container.DataItem.ToString() %> 
       </ItemTemplate> 
      </asp:TemplateField> 

發生這種情況後，使領域TempleteField。早些時候，該領域如下所示。

<asp:BoundField DataField="!" HeaderText="Role" />

確保在<%#Eval("Role") %>指定OnRowUpdating="gv_RowUpdating"事件，改變字段名，看下面的例子：

.aspx頁面中

<asp:GridView ID="gv" runat="server" DataKeyNames="Id" AutoGenerateColumns="false" OnRowEditing="gv_RowEditing"  
OnRowUpdating="gv_RowUpdating" OnRowCancelingEdit="gv_RowCancelingEdit" OnRowCommand="gv_RowCommand" OnRowDeleting="gv_RowDeleting"> 
<Columns> 
    <asp:TemplateField> 
    <EditItemTemplate> 
     <asp:LinkButton ID="lbtnUpdate" runat="server" CommandName="Update" Text="Update" /> 
     <asp:LinkButton ID="lbtnCancel" runat="server" CommandName="Cancel" Text="Cancel" /> 
    </EditItemTemplate> 
    <ItemTemplate> 
     <asp:LinkButton ID="lbtnEdit" runat="server" CommandName="Edit" Text="Edit" /> 
     <asp:LinkButton ID="lbtnDelete" runat="server" CommandName="Delete" Text="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?')" CausesValidation="false" /> 
    </ItemTemplate>  
    </asp:TemplateField> 
    <asp:TemplateField HeaderText="Role"> 
    <EditItemTemplate> 
     <asp:TextBox ID="txtEditRole" runat="server" Text='<%#Eval("Role") %>' /> 
    </EditItemTemplate> 
    <ItemTemplate> 
     <asp:Label ID="lblRole" runat="server" Text='<%#Eval("Role") %>' /> 
    </ItemTemplate>  
    </asp:TemplateField> 
</Columns> 
</asp:GridView> 

.aspx.cs

protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e) 
{ 
    //your code here.. 
}
