clear button - vb2005

I have RequiredFieldValidator on these four textboxes. The code does not work right. Please help. When I click clear button, some of the required field show right next to the textboxes.

Protected Sub btnClear_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnClear.Click

Me.TextBox1.Text = Nothing
Me.TextBox2.Text = Nothing
Me.TextBox3.Text = Nothing
Me.TextBox4.Text = Nothing

End Sub

Set the property "causesvalidation" of that button to false? What else can you do it beside this?

I'm not sure why you don't want to use CausesValidation, but you can do it another way.

If you disable the client-side validation on your validator control then you could also disable/re-enable it manually on the individual validator controls at the server-side (if, for example, you wanted to disable some validators but leave others active -- for some reason):

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Me.RequiredFieldValidator1.Enabled = False
Me.TextBox1.Text = ""
Me.RequiredFieldValidator1.Enabled = True

End Sub

Here's a sample without code-behind. The one button turns off the validation before it makes the change. The other doesn't.

<%@ Page Language="vb" %>
<script language="vb" runat="server">

Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.RequiredFieldValidator1.Enabled = False
Me.TextBox1.Text = ""
Me.RequiredFieldValidator1.Enabled = True
End Sub

Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.TextBox1.Text = ""
End Sub

</script>

<form id="Form1" method="post" runat="server">
<P>
<asp:Button id="Button1" runat="server" onclick="Button1_Click" Text="Validator Disabled"></asp:Button> 
<asp:Button id="Button2" runat="server" onclick="Button2_Click" Text="Validator Enabled"></asp:Button></P>

<asp:RequiredFieldValidator id="RequiredFieldValidator1" runat="server" ErrorMessage="RequiredFieldValidator"

</form>
