Answer 1

I actually don't know when this happens, but I tend to create all the columns manually. I create the columns in the designer and set the AutoGenerateColumns property to false in my code.

Answer 2

I had the same problem. I couldn't find the AutoGenerate property in my code.

For reasons I do not understand my DataGridView does not have an AutoGenerate property that I can see in my VB code.

I do not see a checkbox on the Edit Columns dialog box.

I do not see an AutoGenerate property in the grid's properties view.

I have Visual Studio Community 2017.

Here's my class properties:

Public Property BatchId As Integer
Public Property Code as String
Public Property Count As Integer
Public Property Description As String
Public Property Id As Integer

So, here's what I did:

1. I went to the form designer.
2. I right-clicked on the DataGridView.
3. I selected Edit Columns.
4. I made sure each column had the DataPropertyName field set to the class property name.

When I ran my application the DataGridView displayed only those columns in my class.

Answer 3

Set AutoGenerateColumns property to False but keep remember do it just before databinding. eg: DataGridView1.AutoGenerateColumns=false; DataGridView1.DataSource=getData();

By default it is set to True.

Answer 4

Try leave first of auto generated columns and set it visibility false. If it don't help try leave all them with Visible=false. Sorry for bad English.

Answer 5

Add this code or change your DataGridView Property AutoGenerateColumns to false

DataGridView1.AutoGenerateColumns=false;
