如何在运行时更改当前单元格 [英] how to change current cell at run time

问题描述

嗨
我的表单只有一个带有5列的datagridview控件
代码在这里

 公共 类 Form2
    私有  Sub  DataGridView1_CellValidating( ByVal 发​​件人目标 对象，
       ByVal  e  As  System.Windows.Forms.DataGridViewCellValidatingEventArgs)
      句柄 DataGridView1.CellValidating
        如果 e.ColumnIndex =  1  然后
            DataGridView1.CurrentCell = 新建 DataGridViewCell( 1 ， 4 )
        结束 如果
    结束 子
结束 类 

我想将当前单元格更改为多孔单元格

如果我给出以下命令:

 myGrid.CurrentCell = 新建 DataGridViewCell( 1 ， myGrid.CurrentCell = DataGridViewCell( 1 ， 3 )

现在我收到此错误消息:
DataGridViewCell是一种类型，不能用作表达式

如果我这样更改命令:

 myGrid.CurrentCell = 我 .myGrid( 1 ， 3 )

我收到此错误:
xxxx.exe中发生了类型为"System.StackOverflowException"的未处理的异常

帮助我更改当前的单元格.

好吧，这是更改当前所选单元格焦点的正确语法.看起来您是从CellValidating事件执行此操作的.当前单元格的焦点已更改后，将触发该事件；如果您要从此处更改当前单元格，则会创建一个无限循环-这将解释StackOverflowException.

尝试改变另一个事件的焦点，例如CellValidated.

要添加答案，您应该买一本书并尝试阅读，而不用猜测随机的事物.找到您想做的事.

嗨
您可以通过以下代码设置datagridview currentcell属性

在vb.net

myGrid.CurrentCell = this.myGrid(1，3);

希望对您有帮助

Well, it''s the right syntax to change the focus of the currently selected cell. Looks like you doing this from the CellValidating-event. That event is triggered after the focus of the current cell has changed; if you''re changing the current cell from there, you''d be creating an infinite loop - and that would explain the StackOverflowException.

Try to change the focus from another event, like CellValidated.

To add to the answer you were given, you should buy a book and try reading it instead of guessing random things to try to find what you want to do.

Hi
you may set the datagridview currentcell property by following code

in vb.net

myGrid.CurrentCell = this.myGrid(1, 3);

hope this helps
