Hello programmers. I need a Help. I am working on my Project in Windows Forms. In this Project I am getting data from Excel file and than I am displaying this data in datagtidview. I want to autoresize datagridview. For Example when it has 2 rows, dgv height must be equal to 2 rows. For width similar . I have code for that but unfortunately, when data in DVG is too much, it has max height, but it is not Scroling.For width it works perfect but Height is a Problem. Scroling function donn't works. here is a Code:

C#

int height = 0;
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                height += row.Height;
            }
            height += dataGridView1.ColumnHeadersHeight;

            int width = 0;
            foreach (DataGridViewColumn col in dataGridView1.Columns)
            {
                width += col.Width;
            }
            width += dataGridView1.RowHeadersWidth;
            dataGridView1.ClientSize = new Size(width + 2, height + 2);

I am working on a similar WinForms app and I have a suitable method that I intend to write a Tip about very soon. Maybe I'll do that this weekend.
The key is that you don't resize the DGV; you resize the Form.

I am resizing a Form and changing it's Position after filling dgv with datas with following code : this.StartPosition = FormStartPosition.Manual;
this.Location = new Point(-10, 0);
this.Height = Screen.PrimaryScreen.WorkingArea.Height;

Solution 1

What ContainerControl (Form ?, Panel ?) is the DataGridView sited in now ?

Please describe what you are doing now (or not doing) with the DataGridView:

Properties:

ScrollBars, ColumnHeadersHeightSizeMode, RowHeadersWidthSizeMode, AllowUserToResizeRows, AllowUserToReSizeColumns, AutoSizeRowsMode, AutoSizeColumnsMode, Anchor, Dock, MinimumSize, MaximumSize

Events:

Have you tried defining a SizeChanged EventHandler, or a RowHeadersWidthChanged handler, or a ColumnHeadersHeightChanged handler, or a UserAddedRow handler ?

I have DGV in Windows Form. So for example I have one From with DGV and one Button. After running it Form size is 300x300 pixels. In that time DGV is exmpty, but after clickinng on Button, I am getting data from DB and display it in DGV. In this OnClick Event Form size changes, it is going on left top corner(this.StartPosition = FormStartPosition.Manual;
this.Location = new Point(-10, 0);) and its height is equal to = (this.Height = Screen.PrimaryScreen.WorkingArea.Height); and now I want to make DGV autoresizable too. Code above for DGV I have found in Internet.
