Question

I have a datagrid in my application. My datagridview columns have very long names and I would like that datagridview would show full text of the column header. I have tried change AutoSizeColumnMode property to ColumnHeader, but I do that then I wont be able to resize the columns, I wont be able to make the cell bigger or smaller.

Wich properties should I change so that my datagridview shows full text on the columns?

Help is very appreciated.

In the Winform designer leave the AutoSizeColumnMode setting to ColumnHeader, but in your form’s constructor (after calling InitializeComponent()) set all your DGV columns AutoSizeColumnMode property to None:

    foreach (DataGridViewColumn col in dataGridView1.Columns) {
        col.AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
    }

When your form loads your DGV Columns will be sized to the column header but your users will be able to resize column widths.
