hi friend, Try this code this is for merging the cells and rows..... using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.Diagnostics; using System.Drawing.Drawing2D; public class HMergedCell : DataGridViewTextBoxCell { private int m_nLeftColumn = 0; private int m_nRightColumn = 0; /// /// Column Index of the left-most cell to be merged. /// This cell controls the merged text. /// public int LeftColumn { get { return m_nLeftColumn; } set { m_nLeftColumn = value; } } /// /// Column Index of the right-most cell to be merged /// public int RightColumn { get { return m_nRightColumn; } set { m_nRightColumn = value; } } protected override void Paint(Graphics graphics, Rectangle clipBounds, Rectangle cellBounds, int rowIndex, DataGridViewElementStates cellState, object value, object formattedValue, string errorText, DataGridViewCellStyle cellStyle, DataGridViewAdvancedBorderStyle advancedBorderStyle, DataGridViewPaintParts paintParts) { try { int mergeindex = ColumnIndex - m_nLeftColumn; int i = 0; int nWidth = 0; int nWidthLeft = 0; string strText = null; Pen pen = new Pen(Brushes.Black); // Draw the background graphics.FillRectangle(new SolidBrush(SystemColors.Control), cellBounds); // Draw the separator for rows graphics.DrawLine(new Pen(new SolidBrush(SystemColors.ControlDark)), cellBounds.Left, cellBounds.Bottom - 1, cellBounds.Right, cellBounds.Bottom - 1); // Draw the right vertical line for the cell if (ColumnIndex == m_nRightColumn) { graphics.DrawLine(new Pen(new SolidBrush(SystemColors.ControlDark)), cellBounds.Right - 1, cellBounds.Top, cellBounds.Right - 1, cellBounds.Bottom); } // Draw the text RectangleF rectDest = RectangleF.Empty; StringFormat sf = new StringFormat(); sf.Alignment = StringAlignment.Center; sf.LineAlignment = StringAlignment.Center; sf.Trimming = StringTrimming.EllipsisCharacter; // Determine the total width of the merged cell nWidth = 0; for (i = m_nLeftColumn; i nWidth += this.OwningRow.Cells(i).Size.Width; } // Determine the width before the current cell. nWidthLeft = 0; for (i = m_nLeftColumn; i nWidthLeft += this.OwningRow.Cells(i).Size.Width; } // Retrieve the text to be displayed strText = this.OwningRow.Cells(m_nLeftColumn).Value.ToString(); rectDest = new RectangleF(cellBounds.Left - nWidthLeft, cellBounds.Top, nWidth, cellBounds.Height); graphics.DrawString(strText, new Font("Arial", 10, FontStyle.Regular), Brushes.Black, rectDest, sf); } catch (Exception ex) { Trace.WriteLine(ex.ToString()); } } } Please Mark as answer if it helps.
