Devexpress GridControl：防止新行自动添加 [英] Devexpress GridControl : Prevent new row added automatically

问题描述

请指导我如何防止在DevExpress.XtraGrid.GridControl上自动添加新行。

Please guide me how to prevent new rows added automatically on DevExpress.XtraGrid.GridControl

我想控制何时添加新行，在我的情况下使用keydown事件（CTRL + I）进行此任务。但是如果我将焦点（光标指针）移动到最后一行的区域，则网格会自动添加新行，然后单击。

I want to control when new rows is added, in my case i'm using a keydown event (CTRL + I ) for this task. But the grid keep adding new rows automatically if i move the focus (cursor pointer) to the area right below to the last row and click.

GridControl.MainView是一个 BandedGridView ，其中包含数据源。

The GridControl.MainView is a BandedGridView, which contains the datasource.

推荐答案

您可以处理ValidateRow事件。如果您设置 e.Valid = false ，则不会添加新行。所以检查你的对象是空的还是无效的，只要输入需要的值就可以免费送行。

You can handle the ValidateRow event. If you set e.Valid = false you wont add a new row. So check if your object is empty or invalid and just if the needed values are typed you give the row free.

private void grvMyView_ValidateRow(object sender, ValidateRowEventArgs e)
{
            if (grvMyView.IsNewItemRow(e.RowHandle))
            {
               MyObject obj = grvMyView.GetRow(e.RowHandle) as MyObject;

               e.Valid = obj.IsValid();
            }
}
