I use myDataTable as dataSource of my lookUpEdit like:

         lookUpEdit.Properties.DataSource = myDataTable.

Now I want two functionalities from lookUpEdit:

(1) Be able to hide some columns when pop up myDataTable;

(2) Be able to add /remove/modify rows from myDataTable when pop up myDataTable.

Thanks in advance for any help!

Hi jane ,

Expand column edit property

click the elipsis in the columns(collection)  property

By default it will be blank.

Click populate columns button below

Then select column and set visibility=false

Enjoy.
