I am using Windows Forms. I have DataGridView and some columns inside it. One of the columns is DataGridViewTextBoxColumn. Is it possible to open a drop down pop up (with autocomplete items) of this column, without editing cell? I mean - if I just click on the cell, pop up opens with items in it.
Please note: I was using DataGridViewComboBox column before - but it is very very slow with large number of items in it (more than 1000). That is why I am using DataGridViewTextBoxColumn - it's working fast, the only problem is that user must edit cell and type something in cell to have pop up opened - I want pop up to be opened on the click of the cell. Any idea?
