Hi all,

I have two DataGridView docked in my Form in which I am setting its AutoSizeMode to Fill I want to change automatically the second DataGridView column Width the same as the first one's column width change.

I tried these two cases:

private void dataGridView1_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
{
    dataGridView2.Columns[e.Column.Index].FillWeight = e.Column.FillWeight;
}

private void dataGridView1_ColumnWidthChanged(object sender, DataGridViewColumnEventArgs e)
{
    dataGridView2.Columns[e.Column.Index].Width = e.Column.Width;
}

In the two cases this error appear when loading the form that contains these two DataGridView :

This operation cannot be performed while an auto-filled column is being resized.

Please can anyone helps me ?

Thank you in advance,
:)

Solution 1

The error message tells you why this fails. You have the AutoSizeMode set to Fill and cannot therefore set the width manually.

You will need to change the AutoSizeMode to either NotSet or None on the grid that you want to set the size manually on.

When I do this The second DataGridView never change its size and each column have the size of the width set to each column forever

I have just made a test project with two datagrids the first has the AutoSizeColumnsMode set to fill the second is set to none. I have used the second of your code snippets. The DGVs have their Anchor set to Left|Top|Right so that they will follow the width of the form. When I run it and adjust the Form's width, the columns in grid 2 adjust to match those in grid 1.

I can only suggest that in your case grid 1 column sizes are set before the event handler gets hooked up. As an experiment try setting your Anchor as described above and run your app then resize the Form. If grid 2 does adjust to match then I am correct.

I have already docked my dataGridViews did it differs from beeing anchored

So long as they resize as the Form resizes, no different.

Solution 2

try this code

C#

foreach (DataGridViewColumn dcol in dataGridView1.Columns)
            {
                dcol.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
            }
