操作无效，因为它导致对SetCurrentCellAddressCore函数的可重入调用“。

问题描述

我有一个列和多行的数据网格。单击单元格时，单元格可编辑。我有一个断言，如果我将单元格值编辑为零并单击下一个单元格，则应在该位置删除单元格（0.00）。但运动我点击下一个单元格 cellEditEnd 方法被调用，在这个方法中，我已经编写了删除单元格的代码。但当它尝试删除单元格但代码 datagrid.rows.RemoveAt（index）然后异常抛出操作无效，因为它导致可重入调用SetCurrentCellAddressCore函数。谷歌搜索时发现了这种情况下的许多解决方法，例如使用带有deegate的beginivoke方法或设置焦点一些控制或在删除单元格之前对网格进行Disbale。但我没有得到解决方案。从网格中删除行时抛出异常。



下面是堆栈跟踪：

Hi,
I have a datagrid of one column and many rows. Cell become editable when i click on the cell. i have a stutation in which if i edit the cell value to zero and click on the next cell then leaving cell (0.00) should be remove at that location. But movement i click on next cell cellEditEnd methos gets called and in this method i have written the code to remove the cell. But when it try to remove the cell but code datagrid.rows.RemoveAt(index) then exception throws "Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function".While googling i found many workaround for this case e.g Using beginivoke method with deegate or set focus some aother controls or Disbale the grid before the remove cell. But i didn't got the solution. Exception throws when removing the rows from the grid.

Below is stack trace:

---> System.InvalidOperationException: Operation is not valid because it results in a reentrant call to the SetCurrentCellAddressCore function.
  at System.Windows.Forms.DataGridView.SetCurrentCellAddressCore(Int32 columnIndex, Int32 rowIndex, Boolean setAnchorCellAddress, Boolean validateCurrentCell, Boolean throughMouseClick)
  at System.Windows.Forms.DataGridView.OnRemovingRow(Int32 rowIndexDeleted, Point& newCurrentCell, Boolean force)
  at System.Windows.Forms.DataGridViewRowCollection.RemoveAtInternal(Int32 index, Boolean force)
  at System.Windows.Forms.DataGridViewRowCollection.RemoveAt(Int32 index)

我的代码是simmilar at下面：

MY code is simmilar at below:

 private void grdListItems_CellEndEdit(object sender, DataGridViewCellEventArgs e)
        {
         if (cellAmt == 0)
          {
           RemoveZeroDollarEntry(e.RowIndex);
          }
         }
And
 private void RemoveZeroDollarEntry(int rowIndex)
        {
          do something...
           grdListItems.Rows.RemoveAt(rowIndex);
        }

任何人都能提供正确的解决方案吗？请。
