Why is a cell ALWAYS selected in my DataGridView

Question

I just dont get this one. No matter what I do, whenever I load my form with a DataGridView, which has two DataGridViewComboBoxColumns inserted, the first cell is always selected by default. I tried setting the focus() for one of my buttons but that did not change anything. I even tried cycling through the selectedCells property of the DataGrid and setting the Selected property to false. NO WHERE in my code, as far as Im aware, do I tell the DataGrid to have a selected cell. Is there some special way I have to do this because of the ComboBoxes? If someone can help and needs to see the code, let me know.. thanks...

Answer 1

Hi,
Have you tried

dataGridView1.ClearSelection();

after you get the data? Hope this helps.

Answer 2

That did not work either. No matter what I do, the first ComboBox Cell of the first COmboboxcolumn in the datagridview is still selected.

Answer 3

Ok, I think I know where in my code this is happening, but I just dont know what to do about it. This is a form that loads from another form, within a bigger application. This is the code used to load the form:

ModuleGroupListEditor glEd = new ModuleGroupListEditor();

glEd.Show();

 

 

After the first line, the form loads and calls that ClearSelection(). But, when the Form Shows, it appears with that first cell selected. I took out the DataGridViewComboBoxColumns to see if they were to blame and the same thing happens. Any ideas?

 

Answer 4

Well I figured out how to get around this, but Im still not sure why this happens. It seems that during the Form.Show the DataGridView Cell gets selected. So I created a .Show Event and entered CurentCell = null and the form loads then the cell is deselected. Im still curious why I have to do this at all.

Answer 5

Glad to hear that you solved the problem. As you said, the ClearSelection should be placed after the Show function. When

Answer 6

Thanks for the help. Why does this not work in the Form.Load event?
