如何垂直打印 [英] how to print vertically

问题描述

我能够在c＃data中显示我的43个动态列在c＃中从左到右从上到下自上而下，但是在打印过程中我无法打印它已经在datagridview中显示了它。

 strFormat1.FormatFlags = StringFormatFlags.DirectionVertical; 

通过使用上面的行，它从右到左打印从上到下，这很难读。

我的问题是如何从左到右垂直标题打印。

要在gridview中显示我使用了下面的代码： -

 DataGridView1.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.EnableResizing; 
 DataGridView1.ColumnHeadersHeight =  50 ; 
 DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader; 
 
  //  这里我们将一个事件处理程序附加到单元格绘制事件 
 DataGridView1.CellPainting + =  new  DataGridViewCellPaintingEventHandler（DataGridView1_CellPainting）; < /   pre  >  
 
  private  < span class =code-keyword> void  DataGridView1_CellPainting（ object  sender，DataGridViewCellPaintingEventArgs e）
 {
 
 < span class =code-comment> //  检查我们是否在标题单元格中！ 
  if （e.RowIndex == -1&& e.ColumnIndex >  =  0 ）
 {
 e.PaintBackgro und（e.ClipBounds， true ）; 
 Rectangle rect =  this  .DataGridView1.GetColumnDisplayRectangle（e.ColumnIndex， true ）; 
大小titleSize = TextRenderer.MeasureText（e.Value.ToString（），e.​​CellStyle.Font）; 
  if （ this  .DataGridView1.ColumnHeadersHeight < ;  titleSize.Width）
 {
  this  .DataGridView1.ColumnHeadersHeight = titleSize.Width; 
} 
 
 e.Graphics.TranslateTransform（ 0 ，titleSize.Width）; 
 e.Graphics.RotateTransform（-90.0F）; 
 
  //  这是底部对齐的关键线 - 我们根据 
  //   ColumnHeadersHeight减去当前文本宽度。 ColumnHeadersHeight是 
  //  所有列的最大值，因为我们绘制了两次单元格 - 尽管这样事实 
  //  在所有用法中可能都不正确！  
 e.Graphics.DrawString（e.Value.ToString（）， this  .Font，Brushes.Black， new  PointF（rect.Y  - （sbsDataGridView1.ColumnHeadersHeight  -  titleSize.Width），rect.X））; 
 
  //  用于比较的旧行 
  //   e.Graphics.DrawString（e.Value.ToString（），this.Font，Brushes.Black，new PointF（rect。 Y，rect.X））;  
 
 
 e.Graphics.RotateTransform（ 90  .0F）; 
 e.Graphics.TranslateTransform（ 0 ，-titleSize.Width）; 
 
 e.Handled =  true ; 
} 
 
} 

打印： -



< pre lang =c＃> foreach （DataGridViewColumn GridCol in DataGridView1.Columns）
{
e.Graphics.FillRectangle（ new SolidBrush（Color.LightGray），
new Rectangle（（ int ）arrColumnLefts [iCount]，iTopMargin，
（ int ）arrColumnWidths [iCount ]，iHeaderHeight））;

e.Graphics.DrawRectangle（Pens.Black，
new Rectangle（（ int ）arrColumnLefts [iCount]，iTopMargin，
（ int ）arrColumnWidths [iCount]，iHeaderHeight））;



e.Graphics.DrawString（GridCol.HeaderText，GridCol.InheritedStyle.Font，
new SolidBrush（GridCol.InheritedStyle.ForeColor），
new RectangleF（（ int ）arrColumnLefts [ iCount]，iTopMargin，
（ int ）arrColumnWidths [iCount]，iHeaderHeight）， strFormat1 ）;


iCount ++;
}


私有 void printDocument1_BeginPrint（< span class =code-keyword> object sender，PrintEventArgs e）

{

try
{
iRow = 0 ;
strFormat1 = new StringFormat（）;
strFormat1.Alignment = StringAlignment.Near;
strFormat1.LineAlignment = StringAlignment.Center;

解决方案

I was able to show my 43 dynamic columns in datagridview in c# vertically left to right bottom-up,but during printing I was not able to print it has I have shown it in datagridview.

strFormat1.FormatFlags = StringFormatFlags.DirectionVertical;

By using the above line, it prints right to left and top to bottom, which is difficult to read.
My question is how to print from left to right vertical headings.
To show in gridview I have used the below code:-

DataGridView1.ColumnHeadersHeightSizeMode = DataGridViewColumnHeadersHeightSizeMode.EnableResizing;
            DataGridView1.ColumnHeadersHeight = 50;
            DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCellsExceptHeader;

            // Here we attach an event handler to the cell painting event
            DataGridView1.CellPainting += new DataGridViewCellPaintingEventHandler(DataGridView1_CellPainting);</pre>

private void DataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {

            // check that we are in a header cell!
            if (e.RowIndex == -1 && e.ColumnIndex >= 0)
            {
                e.PaintBackground(e.ClipBounds, true);
                Rectangle rect = this.DataGridView1.GetColumnDisplayRectangle(e.ColumnIndex, true);
                Size titleSize = TextRenderer.MeasureText(e.Value.ToString(), e.CellStyle.Font);
                if (this.DataGridView1.ColumnHeadersHeight < titleSize.Width)
                {
                    this.DataGridView1.ColumnHeadersHeight = titleSize.Width;
                }

                e.Graphics.TranslateTransform(0, titleSize.Width);
                e.Graphics.RotateTransform(-90.0F);

                // This is the key line for bottom alignment - we adjust the PointF based on the 
                // ColumnHeadersHeight minus the current text width. ColumnHeadersHeight is the
                // maximum of all the columns since we paint cells twice - though this fact
                // may not be true in all usages!   
                e.Graphics.DrawString(e.Value.ToString(), this.Font, Brushes.Black, new PointF(rect.Y - (sbsDataGridView1.ColumnHeadersHeight - titleSize.Width), rect.X));

                // The old line for comparison
                //e.Graphics.DrawString(e.Value.ToString(), this.Font, Brushes.Black, new PointF(rect.Y, rect.X));


                e.Graphics.RotateTransform(90.0F);
                e.Graphics.TranslateTransform(0, -titleSize.Width);
                
                e.Handled = true;
            }

        }

For printing :-

foreach (DataGridViewColumn GridCol in DataGridView1.Columns)
{
    e.Graphics.FillRectangle(new SolidBrush(Color.LightGray),
        new Rectangle((int)arrColumnLefts[iCount], iTopMargin,
        (int)arrColumnWidths[iCount], iHeaderHeight));

    e.Graphics.DrawRectangle(Pens.Black,
        new Rectangle((int)arrColumnLefts[iCount], iTopMargin,
        (int)arrColumnWidths[iCount], iHeaderHeight));



    e.Graphics.DrawString(GridCol.HeaderText, GridCol.InheritedStyle.Font,
        new SolidBrush(GridCol.InheritedStyle.ForeColor),
        new RectangleF((int)arrColumnLefts[iCount], iTopMargin,
        (int)arrColumnWidths[iCount], iHeaderHeight), strFormat1);


    iCount++;
}


private void printDocument1_BeginPrint(object sender, PrintEventArgs e)

{

try
{
iRow = 0;
strFormat1 = new StringFormat();
strFormat1.Alignment = StringAlignment.Near;
strFormat1.LineAlignment = StringAlignment.Center;
