Gridview多选复选框

Question

在上图中提到

朋友有如上所述的WinForm，然后在GridView中删除所选行时右键单击复选框。

感谢。

Answer 1

您可以使用以下代码从GridView中删除所选行：

private void deleteButton_Click(object sender, EventArgs e)
{
    gridView1.GetSelectedRows();
    GridView view = gridControl1.FocusedView as GridView;
    view.DeleteSelectedRows();
    //DB.SubmitChanges();
}

或代码：

private void deleteButton_Click(object sender, EventArgs e)
{
    GridView view = gridControl1.FocusedView as GridView;
    if (view == null || view.SelectedRowsCount == 0) return;

    DataRow[] rows = new DataRow[view.SelectedRowsCount];

    for (int i = 0; i < view.SelectedRowsCount; i++)
        rows[i] = view.GetDataRow(view.GetSelectedRows()[i]);

    view.BeginSort();

    try
    {
        foreach (DataRow row in rows)
         row.Delete();
    }
    finally
    {
        view.EndSort();
    }
}

您可以在循环for中调用您的删除方法：

foreach (DataRow row in rows)
{
    MyDeleteMethod(row["ColumnNameId"]);
    //You must cast row["ColumnNameId"] to type of parameter
    row.Delete();
}

Answer 2

   private void btnDelete_Click(object sender, EventArgs e)
        {

            GridView view = gridControl1.FocusedView as GridView;
            foreach (var rowHandle in gridView1.GetSelectedRows())
            {
               //you have now dataRow checked for deleting from your database
                DataRow dw = view.GetDataRow(rowHandle);

                //This line for delete the checked rows from your Grid view
                view.DeleteRow(rowHandle);

            }
        }
