Try setting the AutoPostback[^] to true.

Solution 2

hi ,
you need to add the GroupName to the radio button like this:

ASP.NET

<asp:radiobutton id="rblselect" runat="server" enabled="true" repeatdirection="Horizontal" xmlns:asp="#unknown">
        Width="5px" OnSelectedIndexChanged="rbSelector_CheckedChanged" GroupName="Radio" /></asp:radiobutton>

means it will check only one radio button at the same time

Hi,

You need to set AutoPostBack Property of RadioButton to True.
