ASP.NET radio button change

Question

I am trying to figure out why this code doesn\'t fire the radio button change event.

here\'s the ASP page code for 2 radio buttons

Answer 1

You'll need to specify the attribute and value AutoPostBack="true" in order to tell ASP.NET that changing of that element should trigger a postback. It should be applied to each individual RadioButton which you wish to cause a postback.

Answer 2

You should add the AutoPostBack=True attribute to both controls.

Answer 3

You should set the AutoPostBack = True and in the code behind the handles in your function.

Example:

Protected Sub RadioButton1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)           Handles RadioButton1.CheckedChanged

Answer 4

I would use RadioButtonList instead. And set AutoPostBack=true for what you want to do.

Answer 5

you have to specify the AutoPostBack=True for both controls
