I have a form in which I have two textboxes and one fileupload control, I am using required field validator on one textbox and on Fileupload control, When I am clicking the submit button, its showing the validation message but disabling the fileupload control.

I also have second button for Cancel, clicking on which redirects to previous page, when I am clicking this button its also disabling the fileuploadcontrol and not redirecting. Below is my code

XML

<asp:FileUpload ID="FileUpload1" runat="server" />
 <asp:RequiredFieldValidator ID="rfvFileupload" ValidationGroup="validate" runat="server"
                                                ControlToValidate="FileUpload1"></asp:RequiredFieldValidator>


  <asp:TextBox ID="txtSubj" runat="server" ></asp:TextBox><asp:RequiredFieldValidator
                                ID="rfvSubject" ControlToValidate="txtSubj" runat="server" Display="Dynamic"
                                EnableClientScript="true" ErrorMessage="* required" ValidationGroup="validate" />


<asp:Button ID="btnupload" runat="server" Text="Send" ValidationGroup="validate"
                    OnClick="btnupload_Click">
                <asp:Button ID="btncancel" runat="server" Text="Cancel" OnClick="btncancel_Click"
                    />

Validations are being called against the click event of all buttons on the page if not grouped...

So manage your controls in validation groups to avoid the validations being called on each button click....

Required field validator does not disable any other form controls when it fails the validation. Try this below sample

XML

<asp:FileUpload ID="FileUpload1" runat="server" />
        <asp:RequiredFieldValidator ID="rfvFileupload" ValidationGroup="validate" runat="server" Display="Dynamic"
                                          ErrorMessage="* required" ControlToValidate="FileUpload1"></asp:RequiredFieldValidator>


        <asp:TextBox ID="txtSubj" runat="server" ></asp:TextBox>
        <asp:RequiredFieldValidator ID="rfvSubject" ControlToValidate="txtSubj" runat="server" Display="Dynamic"
                                EnableClientScript="true" ErrorMessage="* required" ValidationGroup="validate" />


        <asp:Button ID="btnupload" runat="server" Text="Send" ValidationGroup="validate" onclick="btnupload_Click" />
        <asp:Button ID="btncancel" runat="server" Text="Cancel" onclick="btncancel_Click" />
