In table layout panel, if i drag some particular row,gthe entire panel is moving. I just want to move only the selected row or column. How can i do this?

Using this code to move entire tablelayoutpanel:

private void tableLayoutPanel1_MouseMove(object sender, MouseEventArgs e)
    {
      int GRow = 0;
      int GColumn = 0;

        try
        {
            if (resizing)
            {

                columnStyles[GColumn].SizeType = SizeType.Absolute;
                rowStyles[GRow].SizeType = SizeType.Absolute;
                rowStyles[GRow].Height += e.Y - rowStyles[GRow].Height;
                columnStyles[GColumn].Width += e.X - columnStyles[GColumn].Width;

            }
        }
        catch (Exception ex)
        {
           // MessageBox.Show(ex.ToString());
        }
    }

To get the GRow and GColumn used this below code:

private void tableLayoutPanel1_MouseClick(object sender, MouseEventArgs e)
       {
           try
           {
               int Row = 0;

               int VSpace = 0;
               GRow = Row;
               foreach (int h in tableLayoutPanel1.GetRowHeights())
               {
                   int Column = 0;
                   int HSpace = 0;

                   foreach (int w in tableLayoutPanel1.GetColumnWidths())
                   {
                       Rectangle Rect = new Rectangle(HSpace, VSpace, w, h);
                       if ((Rect.Contains(e.Location)))
                       {
                           GColumn = Column;
                           MessageBox.Show("Row Value = " + Row.ToString() + " " + "Column Value = " + Column.ToString(), "TableLayoutPanel", MessageBoxButtons.OK, MessageBoxIcon.Information);
                           return;
                       }
                       HSpace += w;
                       Column += 1;
                   }
                   VSpace += h;
                   Row += 1;
               }

           }

           catch (Exception ex)
           {
               MessageBox.Show(ex.ToString ());
           }
       }

I want to move only the specific row or column. Help me.

I cant understand what you are saying...

What SAKryukov wants to say is this:
When asking a question, there are 3 input fields: heading, tag and text.
You already used the heading and text fields. Use the tag field as well to improve the possibility of being read and therefore being answered.

If I understand correctly, You want to move the border between two columns. So from that border's point of view, you have a left and a right column.

I'd try something like this:

C#

private System.Windows.Forms.TableLayoutPanelColumnStyle _leftColumnStyle = null;
private System.Windows.Forms.TableLayoutPanelColumnStyle _rightColumnStyle = null;
private System.Drawing.Point _locationWhereUserStartedDragging = new Point(-1, -1);

tableLayoutPanel1_MouseDown(object sender, MouseEventArgs e)
{
    _locationWhereUserStartedDragging = e.Location;

    GetColumnsThatUserClickedInBetween(e, ref _leftColumnStyle, ref _rightColumnStyle);

    foreach(ColumnStyle style in tableLayoutPanel1.ColumnStyles)
    {
        if( style.Equals(_rightColumnStyle))
        {
            style.SizeType = SizeTypes.AutoSize;
        }
        else
        {
            style.SizeType = SizeTypes.Absolute;
        }
    }
}

tableLayoutPanel1_MouseMove(object sender, MouseEventArgs e)
{
    _leftColumnStyle.Width = e.Location.X - _locationWhereUserStartedDragging.X;
}

When the user presses the mouse button down, our application remembers where that was to calculate how far the user may have moved the mouse.
It also remembers the single column that is set to have an automatically calculated width. So when we change the left column's width, the right one should follow.
