Single click anywhere to open and prevent null

[Brandon Devine]

When using a combo box I would like to open the list clicking anywhere inside the combo box and have the user select a value. I would like to prevent typing/inputting any value and force the end user to select only from the list.  Null would not be a valid value.

Hi Brandon,

Greetings from Syncfusion support.

Before proceeding with your requirement, we would like to confirm whether you are using our EJ2 Combo Box component. Refer to the below documentation link and confirm the component.

https://ej2.syncfusion.com/aspnetcore/documentation/combo-box/getting-started

If possible, share the code snippets with us and get back to us if you need any further assistance.

Regards,

I'm sorry I didn't include the ej2 piece.  It is ej2, but I do not have a code snippet because I am not sure how to accomplish my request.

There are two things I was hoping to accomplish. 

First I would like to be able to force the combo to open anytime you click anywhere in the combo box, not just when clicking the drop down arrow.

Second I would like to do something that would disable entry or typing of any kind, in an attempt to force the user to only select items in the datasource directly by clicking.

I hope that helps clear up the request.

You can try Syncfusion's DropdownList component instead of the ComboBox component for your needs. The DropdownList component has a visually appealing appearance and enables users to select a single, non-editable value from a list of predefined values. Please refer to the documentation and online demo shared below for more information about Syncfusion's DropdownList component.

This was exactly what I was looking for.  Thank you very much!
