Hi All
We would like to give the users a button next to the New and Reset buttons near the dropdownlists in detailview edit mode.
An example would be a View Button to a Job Profile dropdownlist where the user can get a view of the description of the job profile.
Regards,
Deven
Hello Deven,
v18.1+
The built-in ASPxGridLookupPropertyEditor provides the Edit button out of the box. You can select this Property Editor Type for your reference properties in the Model Editor of your Web module or project.
Previous solutions:
You can use the ASPxObjectPropertyEditor to edit the referenced object. Please refer to a similar ticket: ASPxLookupPropertyEditor: we have New/Clear but no edit.
Alternatively, open the DetailView in a View mode and click on the hyperlink displayed instead of the lookup editor.
Finally, you can create an ASPxLookupPropertyEditor's descendant and add a custom button to it. Here is an example (we no longer maintain it and there may be issues in newer versions like in t897882):

Hello Dear Andrey,
Thanks for new topic, I have a new question,
I set this button for my LookupPropertyEditor default. But when i clicked a null LookupPropertyEditor, It gets error because GetControlValueCore() gets null. When i null control for this, i get CustomizePopupWindowParams.View error.
How can i solve this problem ?
Thanks for your assistance
