Question

我正在尝试将任何CSV / Excel文件中的数据填充到gridview中。当所有列都可见时，它会上传很好。但是，我根据用户的选择显示/隐藏网格中的列。所以我希望我粘贴的值只填充在网格的可见列中。我在winforms工作。我已将我用于将数据粘贴到网格下面的代码

    //Code for pasting clipboard data into gridview
  private void PopulateImportGrid()
    {
        char[] rowSplitter = {'\r', '\n'};
        char[] columnSplitter = {'\t'};

        //get the text from clipboard
        IDataObject dataInClipboard = Clipboard.GetDataObject();
        if (dataInClipboard != null)
        {
            var stringInClipboard = (string) dataInClipboard.GetData(DataFormats.Text);
            //split it into lines
            string[] rowsInClipboard = stringInClipboard.Split(rowSplitter, StringSplitOptions.RemoveEmptyEntries);

            //     grdSiteDetails.DeferRefresh();
            // loop through the lines, split them into cells and place the values in the corresponding cell.
            using (grdSiteDetails.DeferRefresh())
            {
                for (int iRow = 0; iRow < rowsInClipboard.Length; iRow++)
                {
                    grdSiteDetails.Rows.Add(iRow);
                    //split row into cell values
                    string[] valuesInRow = rowsInClipboard[iRow].Split(columnSplitter);
                    //cycle through cell values
                    for (int iCol = 0; iCol < valuesInRow.Length; iCol++)
                    {
                        //assign cell value, only if it within columns of the grid
                        if (grdSiteDetails.ColumnCount - 1 >= iCol)
                        {
                            grdSiteDetails.Rows[iRow].Cells[iCol].Value = valuesInRow[iCol];
                        }
                    }
                }
            }
        }

        grdSiteDetails.ColumnChooserSortOrder = RadSortOrder.None;
    }`

如何隐藏列？如果您使用以下物业。粘贴时检查相同的属性。

this.dataGridView1.Columns [＆＃34; COLUMNNAME＆＃34]。可见
