将行复制到DataGridView c#中的另一行中

问题描述 投票:1回答:1

我有一个带有带有三列的DataGridView的表单:

enter image description here

[我想做的是复制例如下一个代码

  • codigo |肤浅
    • 335T1612 | 0,28
    • 335T1613 | 0,5
    • 335T1642 | 3,87

并在DataGridView的“ Codigo”和“ Superficie”列中进行介绍。我怎样才能做到这一点?我一直在尝试这篇文章的代码:Link of my code,但是使用此代码,我只是将所有代码复制到第一个单元格[0,0]中。例如,如果我尝试将第一行的内容复制到第二行,则会得到以下信息:

enter image description here

并且应该像这样:

like this

这是我尝试执行的方法:

 private void PasteClipboard()
    {
        System.Diagnostics.Debug.WriteLine("Dentro de PasteClipboard .");
        try
        {
            string s = Clipboard.GetText();
            string[] lines = s.Split('\n');
            int iFail = 0, iRow = dataGridViewTennetPaint.CurrentCell.RowIndex;
            int iCol = dataGridViewTennetPaint.CurrentCell.ColumnIndex;
            DataGridViewCell oCell;
            if (dataGridViewTennetPaint.Rows.Count < lines.Length)
                dataGridViewTennetPaint.Rows.Add(lines.Length - 1);
            foreach (string line in lines)
            {
                System.Diagnostics.Debug.WriteLine("Line contiene: " + line);
                if (iRow < dataGridViewTennetPaint.RowCount && line.Length > 0)
                {
                    string[] sCells = line.Split('\t');
                    for (int i = 0; i < sCells.GetLength(0); ++i)
                    {
                        if (iCol + i < this.dataGridViewTennetPaint.ColumnCount)
                        {
                            oCell = dataGridViewTennetPaint[iCol + i, iRow];
                            if (!oCell.ReadOnly)
                            {
                                if (oCell.Value == null || oCell.Value.ToString() != sCells[i])
                                {
                                    oCell.Value = Convert.ChangeType(sCells[i],
                                                          oCell.ValueType);
                                    //  oCell.Style.BackColor = Color.Tomato;
                                }
                                else
                                    iFail++;
                                //only traps a fail if the data has changed 
                                //and you are pasting into a read only cell
                            }
                        }
                        else
                        { break; }
                    }
                    iRow++;
                }
                else
                { break; }
                if (iFail > 0)
                    MessageBox.Show(string.Format("{0} updates failed due" +
                                    " to read only column setting", iFail));
            }
        }
        catch (FormatException)
        {
            MessageBox.Show("The data you pasted is in the wrong format for the cell");
            return;
        }
    }

}

并且DataGridView的定义如下:

    private System.Windows.Forms.DataGridView dataGridViewTennetPaint;
    private System.Windows.Forms.DataGridViewTextBoxColumn columnCodigo;
    private System.Windows.Forms.DataGridViewTextBoxColumn columnSuperficie;
    private System.Windows.Forms.DataGridViewTextBoxColumn columnError;

提前感谢!

不要编辑每个单元格。您可以像这样添加整行:

 yourDataGrid.Rows.Add("335T1612", "0,5", "");

基本上,dataGridView具有一个名为“行”的集合,您可以使用Add方法向其中添加项目。

此外,由于这只是一个可视控件,而不是向dataGridView添加或删除行,因此最好在内存中存储具有所需值的DataTable,然后将此表用作datagrid的数据源:

 DataTable tabla = new DataTable();

 tabla.Rows.Add("335T1612", "0,5", "");

 yourDataGrid.DataSource = tabla;
