Question

我有一个<条码>DataGridView,我正在从方案上增加行文。

通常,当我增加数据第一行时,<代码>补选火灾

但是,我的Grid被困在形式上和底部,当我把形式缩小,使Grid的高度为零时,当选的<<<>条/代码>活动在增加第一行时不会被击。



Is this by design? It doesn t seem logical to me. 

    With DataGridView1
        .Rows.Clear()
        .Columns.Clear()
        .Columns.Add("Col1", "Col1")
        .Columns.Add("Col2", "Col2")
         uncomment the following line and the SelectionChanged event does not fire
         .Height = 0
        .Rows.Add("foo", "bar")
    End With

Answer 1

每次在<<>隆>上选取或者说,电网看不见,电网高端为零

When a row is selected and you try to select it again at that time event not fired If you need to fire every time this event than first unselect that row and than select the same row in the case this event occure 2 time 1st for unselect and 2nd for row selection

dataGridView2.Rows[index].Selected = false;
dataGridView2.Rows[index].Selected = true;
