datagridviewから列ヘッダーを含むセルをコピーしたいとします。 (行ヘッダーではありません)。DataGridviewのヘッダー付きセルをコピーする
私はこれを試してみましたが、私は例外を取得:
if (dataGridView1.GetCellCount(DataGridViewElementStates.Selected) > 0)
{
foreach (DataGridViewColumn c in dataGridView1.Columns)
{
c.SortMode = DataGridViewColumnSortMode.NotSortable;
}
dataGridView1.SelectionMode = DataGridviewSelectionMode.ColumnHeaderSelect; //only the column headers will be copied
dataGridView1.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableWithAutoHeaderText; //.EnableWithAutoHeaderText;
// Add the selection to the clipboard.
Clipboard.SetDataObject(dataGridView1.GetClipboardContent()); //Here it goes wrong
}
は、これは私が取得例外です。 GetClipbooardのコンテンツは空ですか?
