在 UltraGridCell 中设置值不触发事件
我有一个 UltraGrid，其复选框位于一列中。我有一个事件，当单击其中一个复选框（选中或取消选中）时会触发该事件。
但是，我想稍后通过代码设置复选框的值。我想出了如何通过找到 UltraGridCell 并执行 cell.value = true; 或 cell.value = false; 来做到这一点，但是这个没有触发我需要的事件。我还找到了 cell.SetValue(true,something)，但我不确定将什么传递给 something。这些文档没有任何帮助，而且我找不到可以实现我想要的功能的示例。有什么想法吗？
I have an UltraGrid with checkboxes in one column. I have an event that is fired when one of the checkboxes is clicked (checked or unchecked).
However, I want to set the value of the checkbox through code at a later time. I figured out how to do this by finding the UltraGridCell and doing cell.value = true; or cell.value = false;, but this isn't firing the event, which I need. I also found cell.SetValue(true,something), but I am not sure what to pass into something. The docs are no help, and I can't find an example that does what I want. Any ideas?

您使用哪个事件来确定单元格的值何时发生变化？如果您使用
UltraGrid.AfterCellUpdate，则当使用Value属性或SetValue方法以编程方式设置单元格值时，它将触发。您在 2 个参数重载中好奇的“东西”是一个布尔值，它指示值更改是否应该进入撤消堆栈。如果您传入 True，用户可以在网格上执行撤消操作，并且它将撤消您的编程更改。如果您只设置Value属性，它不会添加到撤消堆栈中。Which event are you using to determine when the value of the cell changes? If you use
UltraGrid.AfterCellUpdate, it will fire when the cell value is set programmatically, either with theValueproperty or theSetValuemethod. The "something" you're curious about in the 2 parameter overload is a boolean value which indicates whether the value change should go onto the undo stack. If you pass in True, the user can perform an undo on the grid and it will undo your programmatic change. If you just set theValueproperty, it does not get added to the undo stack.
