Hi,

I am mainly an asp.net developer but recently I have been working on a small windows application and was struggling to get data to display on a DataGridView control when using AutogenerateColumns set to false.

If I set AutogenerateColumns to true it works perfectly, but why is it not working when I manually set the columns?

Is there something extra that you need to do when using set columns?

BondinASP:
I used the designer to create the columns, whereas your example does everything in code. Is there a difference in using the designer?

I just don't understand why something as simple as creating your own column headers should make it not work. I have worked with Datagrids and Gridviews extensively in asp.net but cannot seem to get things working in a DataGridView.

The DataGridView expands as if it has brought back data but all the fields are blank.

Its weird, because if I take the columns out and set AutoGenerateColumns back to true everything works.

you need to set column.DataPropertyName = "filedname"; property.. this is a key if you are using
AutoGenerateColumns  false
