Aspx page: I bound the lstLocations dynamically. So it look like as below. <telerik:RadListBox ID=”lstLocations” runat=”server” CheckBoxes=”true” Width=”520px” Height=”130px”> </telerik:RadListBox> // Select All checkbox buttons <asp:CheckBox CssClass=”CBFull” ID=”chkSelectAll” runat=”server” Text=”Select All” onclick=”javascript:return ToggleAllLocations(this);” /> // Add below function in javascript function function ToggleAllLocations(checkBox) { //ctl00_ContentPlaceHolder1_RadDockLocFilter_C_lstLocations is a client id of radlistbox var listbox = $find(“ctl00_ContentPlaceHolder1_RadDockLocFilter_C_lstLocations”); …
Telerik RadList Box Checkbox Items check all or uncheck all
