Following required field validator is not working.
Please resolve.

<pre lang="HTML">

<asp:TextBox ID="txtOECCSecurityCode" runat="server" CssClass="textbox3" Width="350"></asp:TextBox>
<asp:RequiredFieldValidator ID="refOECCSecurityCode" runat="server" ControlToValidate="txtOECCSecurityCode" Display="Dynamic" ErrorMessage="" Font-Size="11px" ForeColor="Red" ValidationGroup="vgOE">Security Code required</asp:RequiredFieldValidator>

按钮代码如下

button code as follow

<asp:Button ID="btnEPSubmit" runat="server" Text="Submit" CssClass="button" OnClick="btnEPSubmit_Click"
 OnClientClick="return showContent()" ValidationGroup="vgEP" style="height: 26px" />

推荐答案

This validation does not work, because on button click you are firing onclientclick event. which overrides RequiredFieldValidator. Also, RequiredFieldValidator having ValidationGroup="vgOE" and Button having ValidationGroup="vgEP". This both validationgroup should be same.

希望它有所帮助。

谢谢。

Hope it helps.
