Accessing the Selected Item from a Radio Group

The SelectedItem method tells us which option in a Radio Group is selected allowing us to access it's properties. In the example below we access the value of the Caption property and set it equal to a variable.

myVariable = radGroupName.SelectedItem.Caption 

Radio Groups and If/Else If Statements

We can use an If/ElseIf statement to test the value of the SelectedItem's caption and run related program statements.

If (radColor.SelectedItem.Caption = "Red") then
 lstOut.AddRow("You selected red") 
elseIf (radColor.SelectedItem.Caption = "Blue") then
 lstOut.AddRow("You selected blue") 
elseIf (radColor.SelectedItem.Caption = "Purple") then
 lstOut.AddRow("You selected purple") 
elseIF (radColor.SelectedItem.Caption = "Green") then
 lstOut.AddRow("You selected green") 
End If
