Printing GridView Custom Painting

[Chosi]

How can I print a radGridView with custom painting? See the attached image.

Hello ,

Thank you for writing.

You can use the PrintCellPaint event and add similar code: Events and Customization.

Let me know if I can assist you further.

Here is my RowPaint event:

01.private void grid_RowPaint(object sender, GridViewRowPaintEventArgs e)
02.        {
03.            if (e.Row is GridDataRowElement)
04.            {
05.                GridDataRowElement rowElement = e.Row as GridDataRowElement;
06.
07.                int start = (int)e.Row.RowInfo.Cells["StartCell"].Value;
08.                int end = (int)e.Row.RowInfo.Cells["EndCell"].Value;
09.                Color color = (Color)e.Row.RowInfo.Cells["Color"].Value;
10.
11.                if (end == 0)
12.                    return;
13.
14.                GridDataCellElement startCell = GetCell(rowElement, start);
15.                GridDataCellElement endCell = GetCell(rowElement, end);
16.
17.                if (startCell == null || endCell == null)
18.                {
19.                    return;
20.                }
21.
22.                int left = startCell.PointToControl(startCell.Bounds.Location).X + (startCell.TableElement.CellSpacing * startCell.ColumnIndex);
23.                int right = endCell.PointToControl(new Point(endCell.Bounds.Right, endCell.Bounds.Bottom)).X;
24.
25.                if (grid.RightToLeft == System.Windows.Forms.RightToLeft.Yes)
26.                {
27.                    left = endCell.PointToControl(startCell.Bounds.Location).X + (endCell.TableElement.CellSpacing * startCell.ColumnIndex) - (int)e.Graphics.Transform.OffsetX;
28.                    right = startCell.PointToControl(new Point(startCell.Bounds.Right, startCell.Bounds.Bottom)).X - (int)e.Graphics.Transform.OffsetX;
29.                }
30.
31.                e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;
32.                e.Graphics.SetClip(rowElement.ScrollableColumns.BoundingRectangle);
33.
34.                using (RoundRectShape shape = new RoundRectShape(5))
35.                {
36.                    var rect = new RectangleF(left + 10, 5, (right - left) - 15, e.Row.Size.Height - 10);
37.
38.                    using (GraphicsPath path = shape.CreatePath(rect))
39.                    using (Brush brush = new SolidBrush(color))
40.                    using (Pen pen = new Pen(Color.FromArgb(color.A, (int)(color.R * 0.5), (int)(color.G * 0.5), (int)(color.B * 0.5)), 2))
41.                    {
42.                        e.Graphics.FillPath(brush, path);
43.                        e.Graphics.DrawPath(pen, path);
44.                    }
45.                }
46.            }
47.        }
48.
49.private GridDataCellElement GetCell(GridRowElement rowElement, int phaseId)
50.        {
51.            foreach (GridCellElement cell in rowElement.VisualCells)
52.            {
53.                if (cell.ColumnInfo != null && cell.ColumnInfo.Name == phaseId.ToString())
54.                {
55.                    return cell as GridDataCellElement;
56.                }
57.            }
58.            return null;
59.        }

How should I use this code in PrintCellPaint event?

[Chosi]

As you can see, I have a line as bellow:

GridDataRowElement rowElement = e.Row as GridDataRowElement;

But I cannot use this code in PrintCellPrint event.

Hello ,

Thank you for writing back.

You do not need the row element in this case. You need to know where the shape starts and ends. For example:

private void RadGridView1_PrintCellPaint(object sender, PrintCellPaintEventArgs e)
{
    GridViewDataRowInfo dataRow = e.Row as GridViewDataRowInfo;
    if (dataRow != null)
    {
        bool isStartCell = e.Column.Index == 0;
        bool isEndCell = e.Column.Index == 4;
        bool isMiddle = e.Column.Index > 0 && e.Column.Index < 4;

        var color = Color.Red;

        if (isStartCell)
        {
            using (RoundRectShape shape = new RoundRectShape(5, true, true, false, false))
            {
                var rect = new Rectangle(e.CellRect.X + 3, e.CellRect.Y + 3, e.CellRect.Width - 3, e.CellRect.Height - 6);

                using (GraphicsPath path = shape.CreatePath(rect))
                using (Brush brush = new SolidBrush(color))
                using (Pen pen = new Pen(Color.FromArgb(color.A, (int)(color.R * 0.5), (int)(color.G * 0.5), (int)(color.B * 0.5)), 2))
                {
                    e.Graphics.FillPath(brush, path);
                    e.Graphics.DrawPath(pen, path);
                }
            }
        }

        if (isEndCell)
        {
            using (RoundRectShape shape = new RoundRectShape(5, false, false, true, true))
            {
                var rect = new Rectangle(e.CellRect.X , e.CellRect.Y + 3, e.CellRect.Width - 3, e.CellRect.Height - 6);

                using (GraphicsPath path = shape.CreatePath(rect))
                using (Brush brush = new SolidBrush(color))
                using (Pen pen = new Pen(Color.FromArgb(color.A, (int)(color.R * 0.5), (int)(color.G * 0.5), (int)(color.B * 0.5)), 2))
                {
                    e.Graphics.FillPath(brush, path);
                    e.Graphics.DrawPath(pen, path);
                    e.Graphics.FillRectangle(new SolidBrush(color),e.CellRect.X -2, e.CellRect.Y + 4,4,e.CellRect.Height - 8);
                }
            }
        }

        if (isMiddle)
        {
            using (RoundRectShape shape = new RoundRectShape(5, false, false, false, false))
            {
                var rect = new Rectangle(e.CellRect.X -1, e.CellRect.Y + 3, e.CellRect.Width+2, e.CellRect.Height - 6);

                using (GraphicsPath path = shape.CreatePath(rect))
                using (Brush brush = new SolidBrush(color))
                using (Pen pen = new Pen(Color.FromArgb(color.A, (int)(color.R * 0.5), (int)(color.G * 0.5), (int)(color.B * 0.5)), 2))
                {

                    e.Graphics.FillPath(brush, path);
                    e.Graphics.DrawLine(pen, new Point(e.CellRect.X, e.CellRect.Y + 3), new Point(e.CellRect.X + e.CellRect.Width, e.CellRect.Y+3));
                    e.Graphics.DrawLine(pen, new Point(e.CellRect.X, e.CellRect.Y +e.CellRect.Height - 3), new Point(e.CellRect.X + e.CellRect.Width, e.CellRect.Y+ e.CellRect.Height-3));
                }
            }
        }
    }
}

I hope this will be useful.
