I am not sure if I understood right what you are trying to achieve. Are you trying to do the following:
- Open the DropDownList - at this stage you have the default 10 values;
- Type in the input area, so filtered result has been returned;
- Select one of the returned results (different from the default 10 results);
- Click outside the DropDown;
- Click the DropDoun arrow - when the drop-down opens only the initial 10 values are shown and the selected is not;
If this is your scenario, the reason for the observed is the fact that the input field at this point is empty, so the control returns only the default results. Instead of returning default values, I would suggest you to use Virtualization
with paging and filtering. You will simply have to put your default values on at the begging of the returned collection, so they will be populated initially in the drop-down of the widget.
If the above does not match your scenario, could you please explain a bit more in detail which are the steps that you follow and what is exactly the bottleneck?
Besides that, given that you need filtering and the ability to type in the input area, I would suggest you try the ComboBox
widget / helper instead of DropDownList. The ComboBox is a drop-down widget that by design offers typing in the input area. It also offers server filtering and virtualization.
