Group: StrataFrame Users Posts: 94, Visits: 481	Hello SF Devs, Can you confirm this bug that I am experiencing? I have an SF ComboBox bound to a business object integer property. It is setup to be an AutoComplete ComboBox (Mode: SuggestAppend) and the AutoSelectFirstItemOnValidateForNoSelection is set to true. It works fine until the user types a string that does not match any option in the dropdown and tabs off the control twice in a row. At this point it will throw the following error: Specified cast is not valid. at GKGLibExamples.BusinessObjects.ItemsBO.FieldDescriptor.SetValue(Object component, Object value) in C:\Users\gberrio\Documents\Visual Studio 2008\Projects\GKGLib\GKGLibExamples\BusinessObjects\ItemsBO.Designer.cs:line 1767 at System.Windows.Forms.BindToObject.SetValue(Object value) at System.Windows.Forms.Binding.PullData(Boolean reformat, Boolean force) The value it is trying to set the property to is DBNull. Reproduction Steps: - select the combobox - enter a string that does not return an auto suggest option - tab off the control - select the combobox again - enter a string that does not return an auto suggest option - ! ERROR ! Tags Combobox
