Hello,

What do you mean by row border coordinates? Location of the control inside a form?

Hi,

We have 2 gridVIew on the same screen separated by the panel. we need to draw a line between rows of the grids based on the row data; 

Since gridview also have scroll bars attached to it. so when row is scrolled, i wish to have running coordinates of the row, in that way. on paint event a line will be re-drawn the moment row is scrolled.

for that purpose i need to have border co-ordinates of the row, 

Thanks,
Vishal

Hi,

screenshots cannot be placed, but can you tell me on how to have coordinates of  a row on rowformatting event.

I have placed screenshot now, with lines been drawn, but as you can see when the scroll event will fire, as the coordinates are static; the lines will not be re-drawn. I want to re-draw lines against the mapped rows. so when the mapped rows are moved/ or are out of visible area. lines are again drawn; as row coordinates have changed.

Hello again,

You could try registering for the CellFormatting event and getting the Cell.LocationToControl,

void grid_CellFormatting(object sender, CellFormattingEventArgs e)
{
    e.CellElement.Text = e.CellElement.LocationToControl().ToString();
}

But from what i see it's not very reliable...

Hi guys,

Thank you for writing.

You could use the 'Paint' event for the drawing. In order to apply the new painting the panel should be re-painted. This can be achieved by calling its Invalidate method. The Invalidate method cause repainting of the whole control, which apparently raises the RowPaint event. Here is a sample demo:

radPanel1.Paint += new PaintEventHandler(radPanel1_Paint);

radGridView1.TableElement.VScrollBar.Scroll += new ScrollEventHandler(VScrollBar_Scroll);

 

void radPanel1_Paint(object sender, PaintEventArgs e)

{

    Graphics g = e.Graphics;

  

    foreach (GridRowElement row in radGridView1.TableElement.VisualRows)

    {

        GridDataRowElement dataRow = row as GridDataRowElement;

        if (dataRow != null)

        {

            Point location = dataRow.ControlBoundingRectangle.Location;

            g.DrawLine(Pens.Blue, 10, location.Y, 200, location.Y);

        }

    }

}
 

void VScrollBar_Scroll(object sender, ScrollEventArgs e)

{

    radPanel1.Invalidate();

}

I hope that you find this information useful.
