文本框的requiredfieldvalidator [英] requiredfieldvalidator to textbox

问题描述

我有一张桌子，桌子上有一个文本框

I have a table and in the table one textbox

<asp:TextBox ID="TextBox1" runat="server">
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Insert the Category" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>

<asp:Button ID="Button5" runat="server" onclick="Button1_Click" Text="Submit"  Font-Bold="true"/>

<asp:Button

            ID="Button8" runat="server" onclick="Button4_Click" Text="Category View" />

可以在两个按钮上都进行验证，但是我只希望在button5上进行验证.

It is validated on both button but I want only on button5

推荐答案

尝试在button5，RFV和Textbox1中添加ValidationGroup，如下所示.

Try adding ValidationGroup in button5, RFV and Textbox1 as show below.

<asp:TextBox ID="TextBox1" runat="server"  ValidationGroup="abc">
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Insert the Category" ControlToValidate="TextBox1" ValidationGroup="abc">< /asp:RequiredFieldValidator>

<asp:Button ID="Button5" runat="server" onclick="Button1_Click" Text="Submit"  Font-Bold="true" ValidationGroup="abc"/>

<asp:Button

            ID="Button8" runat="server" onclick="Button4_Click" Text="Category View" />

尝试这段代码:

Hi try this code:

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ValidationGroup="btn" ErrorMessage="Insert the Category" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>


                        <asp:Button ID="Button5" runat="server" onclick="Button1_Click" Text="Submit" ValidationGroup="btn" Font-Bold="true"/>

                        <asp:Button ID="Button8" runat="server" onclick="Button4_Click" Text="Category View" />

您不想在哪个按钮上进行验证.
1.右键单击
2.进入物业
3.将CausesValidation属性设置为False.
它将起作用.

On which Button you don''t want to do validation.
1.Right click on button
2.Go in Property
3.Set CausesValidation property to False.
It will works.
