C# need to dynamically create radio buttons and determine which value user selected in Winform
17,152
A simple way to do it is by using the RadioButtons
CheckChanged
event to set a variable that specifies the file that they have chosen by using the RadioButtons
text or Tag
property which you could set to be the file itself?
e.g.
private File f = null;
for (int i = 0; i < 10; i++)
{
ii = new RadioButton();
ii.Text = i.ToString();
ii.Location = new Point(20, tt);
ii.Tag = fileArray[i]; // Assuming you have your files in an array or similar
ii.CheckedChanged += new System.EventHandler(this.Radio_CheckedChanged);
tt = tt + 20;
panel1.Controls.Add(ii);
}
private void Radio_CheckedChanged(object sender, EventArgs e)
{
RadioButton r = (RadioButton)sender;
f = (File)r.Tag;
}
It's certainly not the most elegant way but it would work.

I need to dynamically create radio buttons based on dynamic list. Scenario is like I have list of files shown as Radio button in WinForm. A user clicks on radio button to select file and move forward. I tried doing following as an example
for (int i = 0; i < 10; i++) { ii = new RadioButton(); ii.Text = i.ToString(); ii.Location = new Point(20, tt); tt = tt + 20; panel1.Controls.Add(ii); }
The problem is how would I check which value got selected by user?
