The following code snippet illustrates how you can create a RadioButtonList
control in your .aspx page populated with list items that contain static data:
Note that the Selected property of the control is used to set the default selected list
item from among the collection of list items in the control.
You can also append the list items programmatically. Refer to the following code
snippet given:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
rbListDept.Items.Add(new ListItem("IT"));
rbListDept.Items.Add(new ListItem("Sales"));
rbListDept.Items.Add(new ListItem("Admin"));
rbListDept.Items.Add(new ListItem("HR"));
rbListDept.Items[0].Selected = true;
}
}
Selecting a List Item
Drag-and-drop a button and a Label control onto your web form. In the Click event
of the Button control, write the following code to retrieve the text of the selected list
item in the RadioButtonList control.
