复制是GridControl自带的属性,主要解决的是多个单元格复制的问题,这里涉及到两个参数
主要是粘贴的
先定义两个全局变量,在单元格点击事件的时候获取单元格的行号和列号
//获取当前选中单元格所在的列序号
int curntindex;
//获取获取当前选中单元格所在的行序号
int rowindex;
private void GV_RowCellClick(object sender, RowCellClickEventArgs e)
{
//获取当前选中单元格所在的列序号
curntindex = e.Column.ColumnHandle;
//获取获取当前选中单元格所在的行序号
rowindex = e.RowHandle;
//MessageBox.Show(curntindex.ToString());
//MessageBox.Show(rowindex.ToString());
}
然后定义个函数,对剪切板的数据进行格式处理
private void Paste()
{
try
{
GridControl x = (GridControl)gridControl1;
DataTable dt = x.DataSource as DataTable;
// 获取剪切板的内容,并按行分割
string pasteText = Clipboard.GetText();
MessageBox.Show(pasteText);
if (string.IsNullOrEmpty(pasteText))
{
MessageBox.Show("剪切板内容为空,请重新复制!");
return;
}
int tnum = 0;
int nnum = 0;
//获得当前剪贴板内容的行、列数
for (int i = 0; i < pasteText.Length; i++)
{
if (pasteText.Substring(i, 1) == "\t")
{
tnum++;
}
if (pasteText.Substring(i, 1) == "\n")
{
nnum++;
}
}
Object[,] data;
//粘贴板上的数据来自于EXCEL时,每行末都有\n,在DATAGRIDVIEW内复制时,最后一行末没有\n
if (pasteText.Substring(pasteText.Length - 1, 1) == "\n")
{
nnum = nnum - 1;
}
tnum = tnum / (nnum + 1);
data = new object[nnum + 1, tnum + 1];//定义一个二维数组
String rowstr;
rowstr = "";
//MessageBox.Show(pasteText.IndexOf("B").ToString());
//对数组赋值
for (int i = 0; i < (nnum + 1); i++)
{
for (int colIndex = 0; colIndex < (tnum + 1); colIndex++)
{
//一行中的最后一列
if (colIndex == tnum && pasteText.IndexOf("\r") != -1)
{
rowstr = pasteText.Substring(0, pasteText.IndexOf("\r"));
}
//最后一行的最后一列
if (colIndex == tnum && pasteText.IndexOf("\r") == -1)
{
rowstr = pasteText.Substring(0);
}
//其他行列
if (colIndex != tnum)
{
rowstr = pasteText.Substring(0, pasteText.IndexOf("\t"));
pasteText = pasteText.Substring(pasteText.IndexOf("\t") + 1);
}
data[i, colIndex] = rowstr;
}
//截取下一行数据
pasteText = pasteText.Substring(pasteText.IndexOf("\n") + 1);
}
for (int j = 0; j < (nnum + 1); j++)
{
for (int colIndex = 0; colIndex < (tnum + 1); colIndex++)
{
this.GV.GetDataRow(j + rowindex)[colIndex + curntindex] = data[j, colIndex];
//GV.Rows[j + rowindex].Cells[colIndex + curntindex].Value = data[j, colIndex];
}
}
//string[] lines = pasteText.Split(new char[] { ' ', ' ' });
//string s = String.Join("' '", lines);
//MessageBox.Show(s);
//foreach (string line in lines)
//{
// if (string.IsNullOrEmpty(line.Trim()))
// continue;
// // 按 Tab 分割数据
// string[] vals = line.Split(' ');
// dt.Rows.Add(vals);
}
catch
{
// 不处理
}
}
然后在GridView的KeyDown事件设置粘贴快捷键Ctrl+V
private void Grid_KeyDown(object sender, KeyEventArgs e)
{
if ((e.Control == true) && e.KeyCode == Keys.V)
{
Paste();
}
}
