What is the DataGridView event that is fired when a cell value is changed programmatically? (Not by user edit)

问题 I have a DataGridView with three columns, start time, end time and duration. When a user edits the start or end time, the duration gets updated programmatically. I'd like to capture the event that is fired when that duration column gets updated in their respective cell, since I want to do a little visual effect by animating the background colour of that cell, showing it was updated programmatically. My DataGridView is not in virtual mode. Does an event like that exist? The CellValueChanged

问题 The following code snippet (The question is here: http://www.vbdotnetforums.com/winforms-grids/10038-fill-datagridview-combobox-column.html) is for filling a combobox cell in a datagridview in unbound mode: Dim dgvcc As DataGridViewComboBoxCell dgvcc = DataGridView1.Rows(2).Cells(0) dgvcc.Items.Add("comboitem1") dgvcc.Items.Add("comboitem2") I'm trying to do likewise but I can't help but notice that the casting operation is invalid and that's the exact error VB gives me. I've tweaked the code

谈关于在datagridview上执行操作后的刷新方法 c#

3 月,跳不动了?>>> 之前,在项目工作中,用到了dataGridView控件,单击选择某一条记录后,实现将该记录从数据库表中删除并刷新dataGridView,之前的做法是: 读取数据填充dataset,然后绑定dataGridView,单击删除按钮,执行SQL删除命令, 刷新 (重新读取数据 填充dataset,再重新绑定dataGridView),后来发现当填充的数据量过大时,上万条时,发现有些迟钝了,仔细琢磨后(金山词霸的生词本给了灵感)——局部刷新 1 读取数据填充dataset,赋给Datatable dt ; 2 将Ddatatable的所有行赋给 DataRowCollection drc; 3在dataGridView的单元格单击事件中,获取要删除的行的索引 index; 4执行drc.RemoveAt(index); 删除该行数据; 5重新绑定DataGridView1.DataSource = dt; 以上五步实现了局部刷新,即使数据量很大的时候,刷新操作也是秒杀,没有任何延迟不爽的地方! 但是,这仅仅是实现了dataGridView的刷新操作,但是数据库并没有执行删除操作,不急,此时只需要在第六步执行SQL删除操作即可。 先SQL 后刷新 和 先刷新后SQL 的区别 在哪里? 给用户的体验,, 先SQL 后刷新执行起来好像比 先刷新后SQL 慢一些
