C#: DataGridView with DataGridViewColumn

Question

I got an Application with a DataGridView. When I'm adding a new DataGridViewColumn to it, the whole Window is white and no DataGridView appears. I searched for this problem but found nothing.

columns is an Array of Strings

foreach (String strings in columns) {
            DataGridViewColumn column = new DataGridViewColumn();
            column.Name = strings;
            column.HeaderText = strings;
            grid.Columns.Add(column);
}

But when I'm adding a new Column without instancing a new DataGridViewColumn, the DataGridView appears in the Window:

foreach (String strings in columns) {
            grid.Columns.Add(strings, strings);
}

The problem is that I have to have these DataGridViewColumns in my App. What can I do?

Answer 1

You should be getting an error, but in any case, you have to specify the column type:

var column = new DataGridViewTextBoxColumn();
column.Name = strings;
column.HeaderText = strings;
grid.Columns.Add(column);
