How to set DataGridView default Columns Width?

Hi,

You can do it by like this.

for (int i = 0; i < DataGridView1.Columns.Count; i++)
{
    DataGridView1.Columns[i].Width = 30;
}

or you can write the event 

dataGridView1.ColumnAdded += new DataGridViewColumnEventHandler(dataGridView1_ColumnAdded);


void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)


{


e.Column.Width = 30;


}
