RangeValidator not working properly
I'm trying to use a validator. The problem is that when I run my code, the validator evaluates to true no matter what the input is. I have the following in an .ascx file:
Code:
<asp:Button ID="btn" runat="server" Text="submit"
CausesValidation="false" onclick="btn_Click" />
<asp:TextBox ID="txtInput" runat="server" TextMode="SingleLine"
ReadOnly="false"></asp:TextBox>
<asp:RangeValidator id="RangeValidator1" Display="Dynamic"
ControlToValidate="txtInput" Type="Integer"
MinimumValue="0" MaximumValue="512"
ErrorMessage="There is an error in the input" runat="server" />
and I have this in the code behind:
Code:
protected void btn_Click(object sender, EventArgs e){
if (!RangeValidator1.IsValid) return;
}
RangeValidator1.IsValid, for some reason, always evaluates to true. How can I make validation work for the integer range of 0-512?
