the C# code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace MyWebApplication
{
public partial class MyWebForm : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
bool Foo1(string bar)
{
if (bar == "bar")
return true;
return false;
}
protected void Foo2(object source, ServerValidateEventArgs args)
{
args.IsValid = this.Foo1(this.MyTextBox.Text);
} // breakpoint
}
}
I set breakpoint in the Foo2 function (comment), but debugger hasn’t visited it. I tried writing diffrent text, not writting anything and writting “bar” and pushing enter and tab after that, but it still doesn’t work. I mean text changing action. Is it possible?
There’s no submit button. You need to add a button to submit the form, which will then trigger page validation.
