Dynamic event handling

[navin]

Hi,
i have posted it before but i got no help...

I am developing a quiz application where the answers for the quiz vary
in number, so i am creating checkbox and radio buttons depending on the

database result.
now my problem is i have to check the which controls are checked in a
button click.
I dont know how many controls will be added to the form. So how do i
actually catch the events.

Help me in this context..
bye,
navin

This example should help you

private void CreateComponents(string[] questions) {
for (int i=0;i<questions.Length;i++){
CheckBox chkBox = new CheckBox();
chkBox.Name = "chk"+i;
chkBox.Text = questions[i];
chkBox.Click += new System.EventHandler(this.CheckBoxHandler);
}
}

private void CheckBoxHandler(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
//and here you have access at the checkbox
}

Navin,

unfortunately I don't know VB.NET so I can not help you with that. The
sure is that the code above can handle events fror n dynamicly created
controls.

Try to adapt it to vb... or anyone else ?
