DataTemplate 中的 Silverlight 组合框首次单击时打开
我的网格上的数据模板中有一个组合框，我想在第一次单击时打开它，但似乎首先选择了该行。我尝试更改 isDropDown 在 rowchange 上打开，但由于某种原因它不起作用。我还尝试从 PreparingCellForEdit 打开下拉菜单，但从未被触发。有什么建议吗？
I've got a combobox in a datatemplate on my grid, I would like to open it on the first click but it seems that the row is selected first. I have tried changing the isDropDown open on rowchange but for some reason it's not working. I have also tried opening the dropdown from PreparingCellForEdit but that was never fired. Any suggestions?

没关系，我正在触发一个 datgrid 事件，该事件从后面的代码中调用故事板，我将假设由于焦点或某些原因关闭了组合框。抱歉，导致关闭的不是故事板，而是 BusyIndicator
nevermind, I was triggering a datgrid event which called a storyboard from code behind which I am going to assume because of focus or something closed the combobox. Sorry, it wasn't the storyboard but the BusyIndicator that caused the close
