Hi Saiansh,

Refer below sample code and bind data to Telerik radCheckedlist List.

I have binded it to CheckBoxList.

HTML

<asp:CheckBoxList runat="server" ID="cblDB" AutoPostBack="true" OnSelectedIndexChanged="cblDB_SelectedIndexChanged">
</asp:CheckBoxList>
<asp:Label ID="Label1" runat="server" />
<asp:Label ID="Label2" runat="server" />
