The RadioButton control is used
to display a Radio Button.RadioButton control allow users to select from a small
set of mutually-exclusive, pre-defined choices. The controls allow you to define
any number of radio buttons with labels and to arrange them horizontally or
vertically.We can select only One RadioButton at a time.it is similar to
CheckBox but RadioButtons are displayed
as rounded instead of box.
The class
hierarchy for this control is as follows:
- Object
- Control
- Webcontrol
- CheckBox
- Radiobutton
Radiobutton Event
The default event of the RadioButton is the
CheckedChanged event
RadioButton Sample
Drag two radio button's, a textbox and Two
button on to the form. Select each radio button and set the GroupName property
for each to ABC. If you do not set the GroupName property to a common name then
each radio button will act differently and when you make a selection all radio
buttons will be rounded. In most cases, you want your users to select only one
option from a given list and to accompolish that you need to set the GroupName
property.
The form will look like bolow when we drag all
the controls
Then we put this code on the double click of
the submit button and reset button
Private Sub Button1_Click(ByVal
sender As System.Object,
ByVal e As
System.EventArgs)
Handles Button1.Click
If RadioButton1.Checked Then
TextBox1.Text = "You Clicked"
& " " & RadioButton1.Text()
ElseIf RadioButton2.Checked Then
TextBox1.Text = "Your Clicked"
& " " & RadioButton2.Text()
End If
End Sub
Private Sub Button2_Click(ByVal
sender As System.Object,
ByVal e As
System.EventArgs)
Handles Button2.Click
TextBox1.Text = ""
End Sub
End Class
Output:
