hi..

f you use ASP.NET radio buttons, the framework renders each radio button with a distinct name attribute so that they do not function as a group. This means that users can select all the radio buttons, and not just one.

Possible solution

Use ordinary HTML radio buttons bound as follows:

<input type="radio" name="listViewSelect" value='<%# Eval("RecordID") %>' />

You can use any value for the name attribute. Where this code has “RecordID” you need any field you can use to distinguish one item from another. To determine which item was selected, use something like the following to retrieve the value of RecordID:

Dim selection As String = Request.Form("listViewSelect")

If you are asking for windows application then you cannot add radiobuttons inside the listview But you can add the images in the listView

and if you want to allow only select one item at a time then Set the property MultiSelect=False
