Hi friend.

(WinForm)

I need to create a custom space between Columns header's row and the first row of the datagridview . in C# 2010 (Win Form) . so that i'll be able to put some controls in the created space .

I create a new Class (inherited from DataGridViewRow) and overrided the OnPaint() method of the Base class . But it only Shift the rows Down and when i click on one of the shifted down rows (In DataGridView at run time) it never display the row in correct format and colors.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Windows.Forms.VisualStyles;
using System.Collections;
using System.Reflection;
namespace DRC.Controls
{
    class Class1Row : DataGridViewRow
    {
        protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle rowBounds, int rowIndex, DataGridViewElementStates rowState, bool isFirstDisplayedRow, bool isLastVisibleRow)
        {
            rowBounds = new Rectangle(rowBounds.X, rowBounds.Y+22, rowBounds.Width, rowBounds.Height);
            clipBounds = new Rectangle(clipBounds.X, clipBounds.Y + 22, clipBounds.Width, clipBounds.Height);
            base.Paint(graphics, clipBounds, rowBounds, rowIndex, rowState, isFirstDisplayedRow, isLastVisibleRow);
           
        }
        
    }
}

This is the picture of my work and what i need .

And in My owen DataGridView

I wrote this codes

public partial class DRCDataGridView : DataGridView
        {
public DRCDataGridView()
            {
                InitializeComponent();
                RowTemplate = new Class1Row();      
      }
            public DRCDataGridView(IContainer container)
            {
                container.Add(this);
                InitializeComponent();               
            }
            protected override void OnPaint(PaintEventArgs pe)
            {
                Rectangle ClipRectangle = new Rectangle(pe.ClipRectangle.X, pe.ClipRectangle.Y + 22, pe.ClipRectangle.Width, pe.ClipRectangle.Height);
                PaintEventArgs p = new PaintEventArgs(pe.Graphics, ClipRectangle);
                base.OnPaint(pe);
            }
            protected override void OnRowPrePaint(DataGridViewRowPrePaintEventArgs e)
            {
                e.ClipBounds = new Rectangle(e.ClipBounds.X, e.ClipBounds.Y + 22, e.ClipBounds.Width, e.ClipBounds.Height);
                base.OnRowPrePaint(e);
            }
            protected override void OnRowPostPaint(DataGridViewRowPostPaintEventArgs e)
            {                
                e.ClipBounds = new Rectangle(e.ClipBounds.X, e.ClipBounds.Y + 22, e.ClipBounds.Width, e.ClipBounds.Height);                
                base.OnRowPostPaint(e);
            }
            protected override void OnCellBeginEdit(DataGridViewCellCancelEventArgs e)
            {                
                base.OnCellBeginEdit(e);
            }
            
            protected override void OnCellPainting(DataGridViewCellPaintingEventArgs e)
            {
                Rectangle Clipbound  = new Rectangle(e.ClipBounds.X,e.ClipBounds.Y+22,e.ClipBounds.Width,e.ClipBounds.Height);
                Rectangle CellBound = new Rectangle(e.CellBounds.X, e.CellBounds.Y+22, e.CellBounds.Width, e.CellBounds.Height);
                DataGridViewCellPaintingEventArgs k = new DataGridViewCellPaintingEventArgs(this, e.Graphics, Clipbound, CellBound, e.RowIndex, e.ColumnIndex, e.State, e, e, "", e.CellStyle, e.AdvancedBorderStyle, e.PaintParts);
                base.OnCellPainting(k);
            }
            protected override void OnPaintBackground(PaintEventArgs pevent)
            {
                base.OnPaintBackground(pevent);
            }
            protected override void OnColumnAdded(DataGridViewColumnEventArgs e)
            {
                base.OnColumnAdded(e);
         }
}
