Question

我在linkbutton控件的InsertItemTemplate内有以下FormView：

<InsertItemTemplate>
    <asp:Table runat="server" id="tabInst">
        <asp:TableRow>
            <asp:TableCell CssClass="PropertyLabel">Instrument ID:</asp:TableCell>

                <asp:TextBox id="tbID" runat="server" Text='<%# Eval("InstID")%>' MaxLength="20"/>
                <asp:RequiredFieldValidator ID="reqValID" runat="server" ControlToValidate="tbID" CssClass="Validator" Display="Dynamic" ErrorMessage="Please enter an Instrument ID">*</asp:RequiredFieldValidator>

    <asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert" Text="Insert" Visible="false" OnClick="InsertButton_Click"/>
    &nbsp;<asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False" CommandName="Cancel" Text="Cancel" Visible="false" />
    <asp:ValidationSummary ID="valSum1" runat="server" CssClass="Validator" HeaderText="Please correct the following errors:"  />
</InsertItemTemplate>

调用OnClick事件的代码是：

    public bool Insert()
    {
        LinkButton lbInsert = (LinkButton) fvInst.FindControl("InsertButton");
        InsertButton_Click(lbInsert, EventArgs.Empty);
    }

我已经确认我有正确的按钮并且输入了InsertButton_Click函数。但是，不会执行验证，也不会触发在物理单击按钮时发生的ItemInserting事件。

感谢。

您可以将代码移动到单独的方法中，并以编程方式调用该方法。 linkbutton的onclick方法也可以调用该方法。

如何在ASP.Net中使用commandName以编程方式在FormView中执行链接按钮？
