There is a certain scenario which will always crash the PropertyGrid control. If you edit an item in the grid and then click another item in the grid (without first hitting <Enter> to submit the change), the grid will crash if the categories are cleared in the 'ValueChanged' event. If you hit <Enter> before changing your selection, you will not crash. The attached project and exe file (attached in message below) demonstrates this issue (Requires v8.61 of PropertyGrid). Launch the PropGridCrash.exe file. Edit the value of Item 1. Without hitting <Enter>, click on the value of Item 2. The application will crash when the 'Categories.Clear' method is called in the 'ValueChanged' event of the PropertyGrid. This same bug is actually apparent in the Designer Studio as well (although it could be caused by something other than the 'Categories.Clear' method). Open the Designer Studio and a standard template will be automatically loaded. Click the 'New' control in the 'Controls' pane. In the 'Properties' pane, change the 'ID' value from 'ID_FIEW_NEW' to 'ID_NEW'. Without first hitting <Enter>, now click on the empty value for the 'Icon ID' property. The Designer Studio will crash. Codejock, I hope a fix for this bug can make it into the 8.62 release. Please let me know what your plans will be for providing a solution because this issue is preventing me from implementing the PropertyGrid in my application. Thanks!! |

Boyd, Where is the attachment? I noticed the bug in the Designer Studio as well. But I havent been able to reproduce the error in an application I created myself. I have tried with bound and regular grid items. |

| Ok,I see what you mean. It crashes here as well. Both the designer and property grid crash on the same line of code. Maybe the Clear method is clearing the value before it is actually updated. |
