如何只從c中的datagridview打印選中的行＃

Question

我有一個Datagridview它有一個checkboxcolumn！ 當數據加載標準的所有行得到檢查！但我需要取消它們中的一些和它們，將它的值發送到var並打印它！

是否有可能？

例：

-------------------------------------------------------------- 
ColumnCheckBox  | Column1  | Column2  | Column3 
-------------------------------------------------------------- 
checked   | 1251000014 | portraitx  | U$ 125.00 
checked   | 1251000021 | notebooky  | U$ 899.96 
unchecked   | 1265888512 | tabletx  | U$ 899.96 
checked   | 1251444251 | iphoness  | U$ 566.26 
unchecked   | 1255222142 | opticalreader | U$ 99.99 

我想選中行的值和發送到VAR和打印了！主要是...如何發送這個值到一個var？

thankx提前！

打印所有的頁籤行：

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) 
{ 
    //Find all checked rows 
    var allCheckedRows = this.myDataGridView.Rows.Cast<DataGridViewRow>() 
           .Where(row => (bool?)row.Cells[0].Value == true) 
           .ToList(); 

    //create a stringBuilder that will contain the string for all checked rows 
    var builder = new StringBuilder(); 

    //For each checked row, create string presentation of row and add to output stringBuilder 
    allCheckedRows.ForEach(row => 
    { 
     //Create an array of all cell value of a row to then concatenate them using a separator 
     var cellValues = row.Cells.Cast<DataGridViewCell>() 
      .Where(cell => cell.ColumnIndex > 0) 
      .Select(cell => string.Format("{0}", cell.Value)) 
      .ToArray(); 

     //Then joiconcatenate values using ", " as separator, and added to output 
     builder.AppendLine(string.Join(", ", cellValues)); 
     //Here instead of adding them to the stringBuilder, you can add int to another list.  
    }); 

    //Print the output string 
    e.Graphics.DrawString(builder.ToString(), 
       this.myDataGridView.Font, 
       new SolidBrush(this.myDataGridView.ForeColor), 
       new RectangleF(0, 0, this.printDocument1.DefaultPageSettings.PrintableArea.Width, this.printDocument1.DefaultPageSettings.PrintableArea.Height)); 
} 

輸出：

1251000014, portraitx, U$ 125.00 
1251000021, notebooky, U$ 899.96 
1251444251, iphoness, U$ 566.26 

打印在一個單獨的頁面中的每個檢查行：

private int currentPrintingRowIndex = 0; 

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) 
{ 
    var allCheckedRows = this.myDataGridView.Rows.Cast<DataGridViewRow>() 
           .Where(row => (bool?)row.Cells[0].Value == true) 
           .ToList(); 

    if (allCheckedRows.Count > currentPrintingRowIndex) 
    { 
     var builder = new StringBuilder(); 
     var currentCheckedRow = allCheckedRows[currentPrintingRowIndex]; 

     var cellValues = currentCheckedRow.Cells.Cast<DataGridViewCell>() 
       .Where(cell => cell.ColumnIndex > 0) 
       .Select(cell => string.Format("{0}", cell.Value)) 
       .ToArray(); 

     builder.AppendLine(string.Join(", ", cellValues)); 

     e.Graphics.DrawString(builder.ToString(), 
        this.myDataGridView.Font, 
        new SolidBrush(this.myDataGridView.ForeColor), 
        new RectangleF(0, 0, this.printDocument1.DefaultPageSettings.PrintableArea.Width, this.printDocument1.DefaultPageSettings.PrintableArea.Height)); 

     currentPrintingRowIndex += 1; 
     e.HasMorePages = allCheckedRows.Count > currentPrintingRowIndex; 
    } 
} 

輸出：

用3頁的文檔：

Page1 content: 1251000014, portraitx, U$ 125.00 
Page2 content: 1251000021, notebooky, U$ 899.96 
Page3 content: 1251444251, iphoness, U$ 566.26

****這是關於以上很有幫助代碼禮Aghaei ****

  private int currentPrintingRowIndex = 0; 

      private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) 

最終代碼
