CalendarExtender fires on target click event. So if you need to open calendar extender when textbox get focus (like with TAB key) it wont work just by itself.

<asp:textbox id="textBoxId" runat="server" />
<asp:RangeValidator id="valDatumRG" ControlToValidate="textBoxId" Type="Date" ... ValidationGroup="valGr" Display="dynamic" runat="server" />
<ajaxToolkit:CalendarExtender ID="cldExtTermin" runat="server" TargetControlID="textBoxId" PopupButtonID="textBoxId" />
Solution

  • Remove PopupButtonID property from the CalendarExtender control
