Text boxes

Vulpes12y ago

If it's a Windows Forms or WPF application, you can do something like this:

double d;

double.TryParse(textBox1.Text, out d);

if (d <= 0.0)

{

MessageBox.Show("Value must be positive");

textBox1.Focus();

return;

}

hi,

Please try with compare validator.

ID="CompareValidator1" runat="server"

ControlToValidate="TextBox1" ErrorMessage=" number Must be > 0"

Operator="GreaterThan" Type="Integer"

ValueToCompare="0" />

Or You can try wth jquery code.

function NumberCheck() {

    var test = parseInt($("#test1").text());

    if(isNaN(increased) || increased <= 0) {

        $("# test1").hide();

NumberCheck();

Hope this will help
