打印datagridview数据C＃ [英] Print datagridview data C#

问题描述

我有数据gridview。有7行。现在我想在datagrid视图中打印所有行。我尝试了很多方法。根据我的代码，只有6行 打印，缺少1行。我如何在我的datagridview中打印所有行？



我尝试过：



private void button4_Click（object sender，EventArgs e）

{

printDocument1.Print（）;

}

private void printDocument1_PrintPage_1（object sender，System.Drawing.Printing.PrintPageEventArgs e）

{

Bitmap bm = new Bitmap（this.dataGridView1.Width， this.dataGridView1.Height）;

dataGridView1.DrawToBitmap（bm，new Rectangle（0,0，this.dataGridView1.Width，this.dataGridView1.Height））;

e.Graphics.DrawImage（bm，0,0）;

}

解决方案

我尝试下面的代码来生成图像，它工作正常

  / /  将DataGridView调整为全高。 
  int  height = dataGridView1.Height; 
 dataGridView1.Height = dataGridView1.RowCount * dataGridView1.RowTemplate.Height; 
 
  //  创建一个位图并在其上绘制DataGridView。 
位图位图= 新位图（此 .dataGridView1.Width，此 .dataGridView1.Height）; 
 dataGridView1.DrawToBitmap（位图， new 矩形（ 0 ， 0 ，此 .dataGridView1.Width，此 .dataGridView1.Height）） ; 
 
  //  将DataGridView调整回原始高度。 
 dataGridView1 .Height =身高; 
 
  //  将位图保存到文件夹。 
位图。保存（ @  D：\ temp \ DataGridView.png）;

解决方案

I tried below code to generate image, its working fine

//Resize DataGridView to full height.
int height = dataGridView1.Height;
dataGridView1.Height = dataGridView1.RowCount * dataGridView1.RowTemplate.Height;

//Create a Bitmap and draw the DataGridView on it.
Bitmap bitmap = new Bitmap(this.dataGridView1.Width, this.dataGridView1.Height);
dataGridView1.DrawToBitmap(bitmap, new Rectangle(0, 0, this.dataGridView1.Width, this.dataGridView1.Height));

//Resize DataGridView back to original height.
dataGridView1.Height = height;

//Save the Bitmap to folder.
bitmap.Save(@"D:\temp\DataGridView.png");
