cdatagridviewresizetabpagewinforms

I want to resize the tabpage, its internal Control which is dataGridview and Finally resize the form in which theay are contained.

I have implemented the Drag functionality of tabpages.Now i want to increase tabPage Size based on the DatagridviewRows.

if(dgv.Rows.count<=15)
  Resize tabPage to show  data to show 'n' No. Of Rows
else if(dgv.Rows.count>15)
  Resize to show 15 Rows data then Scroll bar.

I have tried setting the Dock and Anchor property of gridview.But only the tabpage is filled.I want the tabpage to be resized with increasing No of rows and Finally resize Form in which it is contained.

Kindly help.

I think the better way is to change size of others controls accourding to your form resize.

    private void Form1_Resize(object sender, EventArgs e) //form resize event
    {
      grdView1.SetBounds(Left,Top, this.Width-10,this.Height-10);

      grdView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
      grdView1.Columns[0].FillWeight = 45;

      //same for other columns according to your requirments.

    }

and also set the size of tabpage accourding to Form size.

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

C# – How to automatically resize columns in a DataGridView control AND allow the user to resize the columns on that same grid

This trick works for me:

    grd.DataSource = DT;

    // Set your desired AutoSize Mode:
    grd.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    grd.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    grd.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

    // Now that DataGridView has calculated it's Widths; we can now store each column Width values.
    for (int i = 0; i <= grd.Columns.Count - 1; i++)
    {
        // Store Auto Sized Widths:
        int colw = grd.Columns[i].Width;

        // Remove AutoSizing:
        grd.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;

        // Set Width to calculated AutoSize value:
        grd.Columns[i].Width = colw;
    }

In the Code above: You set the Columns AutoSize Property to whathever AutoSizeMode you need. Then (Column by Column) you store each column Width value (from AutoSize value); Disable the AutoSize Property and finally, set the Column Width to the Width value you previously stored.
