Hello Nazha,

I am just checking if you got this worked out or you still require any assistance or clarification on the matter.

Hello Nazha,

I have been looking into your requirement and the code you have provided and I suggest you use the following code instead of yours:

private void pivotGrid_LayoutLoaded(object sender, EventArgs e)
        {       
            if (pivotGrid.GridLayout.RowHeaderCells[0] != null && this.pivotGrid.DataRows.Count > 1)
            {
                // setting the  RowHeaderCells Column Width

                pivotGrid.GridLayout.RowHeaderCells[0].Column.ColumnWidth = (maxbrandwidth < 120 ? 120 : maxbrandwidth > 200 ? 200 : maxbrandwidth);

                // setting the  DataColumns Column Width

                PivotColumnsPanel obj = GetObject(this.pivotGrid, "ColumnsHeaderPanel") as PivotColumnsPanel;
                obj.SizeChanged += new SizeChangedEventHandler(obj_SizeChanged);
                if (obj.RenderSize.Width > 0)
                {
                    if (nbmonths <= 12)
                    {
                        if (obj.RenderSize.Width > 0)
                        {
                            double columnWidth = obj.RenderSize.Width / nbmonths;
                            for (int index = 0; index < pivotGrid.DataColumns.Count; index++)
                            {
                                pivotGrid.DataColumns[index].ColumnWidth = columnWidth;
                            }
                        }
                    }
                    else
                    {
                        if (obj.RenderSize.Width > 0)
                        {                   
                            for (int index = 0; index < pivotGrid.DataColumns.Count; index++)
                            {
                                pivotGrid.DataColumns[index].ColumnWidth = (int)obj.RenderSize.Width / 12;
                            }
                        }
                    }
                }
            }
        }

        void obj_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            PivotColumnsPanel colheaderpanel = (PivotColumnsPanel)sender;
            if (colheaderpanel.RenderSize.Width > 0)
            {
                for (int index = 0; index < pivotGrid.DataColumns.Count; index++)
                {
                    pivotGrid.DataColumns[index].ColumnWidth = (int)colheaderpanel.RenderSize.Width / 12;
                }
            }
        }

Basically I rounded the Widths to integer, so the lines can redraw correctly. Please let me know if this helps you or you need further assistance.

Looking forward for your reply.
