Is there a limit on # of radio buttons

[=?Utf-8?B?UGFycm90?=]

I have 8 radio buttons on my Windows form but I can only select up to the
first 4. If I click on any button beyond the 4th one and then come back into
the program again the 4th button is always checked instead of the 5th or 6th
etc. I followed the logic thru the debugger and can see where the 5th button
is progammatically checked but the window shows the 4th checked instead.
Does anyone have a clue as to what's going on here? All of the radio buttons
are in a group box.

Here is the form code. I noticed that there are some buttons in between the
radio buttons. Perhaps, that is what is causing the problem. Anyhow, I
deleted the group box and re-added the radio buttons and now it is working
properly. I don't know how it became faulty in the first place. I still
think there is a bug somewhere that caused it to become screwed up because I
designed this window in the same manner as all others using Visual Studio
2005. I did not override any behind the scene code. Thanks to everyone who
replied to this problem. If anyone knows what is faulty about the code
below, please let me know as I normally don't look at the behind the form
code.

I am pasting the entire code for the C# program below. As I mentioned
earlier I can follow the logic in debug mode and I can see where
radiobutton5
is set to checked but it still shows radiobutton4 with the check when the
window is displayed.

namespace WindowsApplicat ion1
{
public partial class convertdate : Form
{

public string xdateformat;

public convertdate(str ing field, string dateformat)
{
InitializeCompo nent();
label2.Text = field;

xdateformat = dateformat;

if (dateformat.Com pareTo("1") == 0)
radioButton1.Ch ecked = true;
else
if (dateformat.Com pareTo("101") == 0)
{
radioButton2.Ch ecked = true;
radioButton1.Ch ecked = false;
}
else
if (dateformat.Com pareTo("107") == 0)
{
radioButton3.Ch ecked = true;
radioButton1.Ch ecked = false;
}
else
if (dateformat.Com pareTo("year") == 0)
{
radioButton4.Ch ecked = true;
radioButton1.Ch ecked = false;
}
else
if (dateformat.Com pareTo("month") == 0)
{
radioButton5.Ch ecked = true;
radioButton1.Ch ecked = false;

}
else
if (dateformat.Com pareTo("day") == 0)
{
radioButton6.Ch ecked = true;
radioButton1.Ch ecked = false;

}
else
if (dateformat.Com pareTo("monthna me") == 0)
{
radioButton7.Ch ecked = true;
radioButton1.Ch ecked = false;
}
else
if (dateformat.Com pareTo("dayname ") ==
0)
{
radioButton8.Ch ecked = true;
radioButton1.Ch ecked = false;
}

}

private void OnCancel(object sender, EventArgs e)
{
this.Close();
}

private void OnOk(object sender, EventArgs e)
{
if (radioButton1.C hecked)
xdateformat = "1";
else
if (radioButton2.C hecked)
xdateformat = "101";
else
if (radioButton3.C hecked)
xdateformat = "107";
else
if (radioButton4.C hecked)
xdateformat = "year";
else
if (radioButton5.C hecked)
xdateformat = "month";
else
if (radioButton6.C hecked)
xdateformat = "day";
else

xdateformat = "monthname" ;

Simply put. the system will not properly handle beyond 3 radio buttons

be a bug could it?

Surely it's a bug. But it's probably in your code.

Unfortunately, you haven't shared that with us. So it's not possible for
us to point it out.

If you can post a concise-but-complete code sample that reliably
reproduces the problem, it should be possible to provide a more complete
answer.

Pete

We need the code behind the form. That's where the grouping of radio
buttons is controlled. You have a grouping error.
