我正在遭受同样的痛苦。最终,我能够开发出一个解决方案,并且它可以毫无问题地工作。我已经提供了构建您自己的解决方案的基本代码。您可以分两步完成您的目标。
step1:将网格视图行复制到剪贴板[按 ctrl+c]
step2:将剪贴板信息粘贴到另一个(或相同)网格视图 [按 ctrl+v]
第一步:示例代码 - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
private void gridView1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control && e.KeyCode == Keys.C)
{
Clipboard.SetText(GetSelectedValues(gridView1));
e.Handled = true;
}
}
private string GetSelectedValues(DevExpress.XtraGrid.Views.Grid.GridView view)
{
//validate selected row count
if (view.SelectedRowsCount == 0) return "";
const string CellDelimiter = "\t";
const string LineDelimiter = "\r\n";
string result = "";
//Iterate cells and compose a tab delimited string of cell values
for (int i = view.SelectedRowsCount - 1; i >= 0; i--)
{
int row = view.GetSelectedRows()[i];
for (int j = 0; j < view.VisibleColumns.Count; j++)
{
result += view.GetRowCellDisplayText(row, view.VisibleColumns[j]);
if (j != view.VisibleColumns.Count - 1)
result += CellDelimiter;
}
if (i != 0)
result += LineDelimiter;
}
return result;
}
*现在您选择的行被复制到剪贴板。因此,如果需要,您可以将这些信息复制到 Excel 或记事本中。提示:Ms.Excel 总是比记事本更智能地格式化内容。
第二步:示例代码 - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
//for retrieving clipboard data
string ClipboardData {
get {
IDataObject iData = Clipboard.GetDataObject();
if(iData == null) return "";
if(iData.GetDataPresent(DataFormats.Text))
return (string)iData.GetData(DataFormats.Text);
return "";
}
set { Clipboard.SetDataObject(value); }
}
DataTable tbl;
private void Form1_Load(object sender, System.EventArgs e) {
//create a datatable as the data-source for grid-control
tbl = new DataTable();
for(int i = 0; i < 3; i++)
tbl.Columns.Add("Column" + i.ToString());
for(int i = 0; i < 4; i++)
tbl.Rows.Add(new object[] { "Item" + i.ToString(), i, 3 - i });
gridControl1.DataSource = tbl;
}
//copy clip board infromation into the grid-view
private void simpleButton1_Click(object sender, System.EventArgs e) {
string[] data = ClipboardData.Split('\n');
if(data.Length < 1) return;
foreach(string row in data) {
AddRow(row);
}
}
void AddRow(string data) {
if(data == string.Empty) return;
string[] rowData = data.Split(new char[] { '\r', '\x09' });
DataRow newRow = tbl.NewRow();
for(int i = 0; i < rowData.Length; i++) {
if(i >= tbl.Columns.Count) break;
newRow[i] = rowData[i];
}
tbl.Rows.Add(newRow);
}
附加代码:(如果需要) - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
如果您想提供选择多行的功能,请使用“MultiSelect”选项,如下例所示。
public fromLoad()
{
InitializeComponent();
gridView1.OptionsSelection.MultiSelect = true;
gridView1.OptionsSelection.MultiSelectMode = GridMultiSelectMode.RowSelect;
gridView1.OptionsBehavior.CopyToClipboardWithColumnHeaders = true;
}
