Set the DataGrid View column width dynamically

Question

Hi
I am using VB.NET 2008.
I have a dataGridView a and wht i want that when form resizes the column should also be resizes. My probelm is that i have to do it programatically. beacuse grid is containes in a Panel.

User can resize by two ways, etither by clicking maximize button, or by resizing the form manually at run time.

Please tell me how can i achieve this.

Answer 1

Did you try setting the dock property?

Answer 2

You can set the dock property to fill or either play with the anchor property of the grid to the panel. Since your panel also needs to resize upon form resize, you also need to set the dock and anchor property of the panel.

Try to play around with these two settings. :)

Answer 3

Hi Progress2007,

Even if you dock the Panel to fill the form and dock the DataGridView to fill the Panel, the columns' width in the DataGridView won't resize when the user resize the form. You need to handle the SizeChanged event of the DataGridView to resize the width of the columns in it. For example:

void dataGridView1_SizeChanged(object sender, EventArgs e)
        {
            for (int i = 0; i < this.dataGridView1.ColumnCount; i++)
            {
                this.dataGridView1.Columns[i].Width = (this.dataGridView1.Width - this.dataGridView1.RowHeadersWidth)/ this.dataGridView1.ColumnCount;
            }
        }

Hope this helps.

Sincerely,
Linda Liu

Answer 4

    Private Sub BOMmain_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Resize
        For a = 0 To SCMpartnersDataGridView.ColumnCount - 1
            SCMpartnersDataGridView.Columns(a).Width = SCMpartnersDataGridView.Width / SCMpartnersDataGridView.ColumnCount
        Next

        SCMpartnersDataGridView.Refresh()
    End Sub
