Hello,
I'm writing a project about exams. The number of answers in the exam are 4. and each one has a RadioButton near it that can be pressed to choose the answer.
What I do to check which of the radio buttons is selected is that I manually add an event (since the number of questions is unknown), and in that event (Checked) I add the event id to a list.
Questions are taken from database (oledbconnection etc.)
while (dr.Read())
{
if (i % 2 == 0)
color = Color.MediumBlue;
else
color = Color.LightBlue;
TableRow final = new TableRow();
TableCell tc_image = new TableCell();
System.Web.UI.WebControls.Image image = new System.Web.UI.WebControls.Image();
image.ImageUrl = dr["Question_Image"].ToString();
image.Width = 200;
image.Height = 200;
tc_image.Controls.Add(image);
tc_image.BackColor = color;
final.Controls.Add(tc_image);

Table1.Rows[i - 1].BackColor = Color.Green;
i++;
}
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
int o = 0;
}
private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
int o = 0;
}
private void radioButton3_CheckedChanged(object sender, EventArgs e)
{
int o = 0;
}
private void radioButton4_CheckedChanged(object sender, EventArgs e)
{
int o = 0;
}What I do is a bit complicated imo but I do that because I want it to be very ordered.
The TableRow is (final), in it there are 4 cells (image,answers,question,number). Inside answers cell there is another table that has in it the radio button, and the answer text.
Here is how it looks after executing:

So why the event is not firing even when we click on the radio button?
