View 3 RepliesI gather MATTER NUMBER and PATENT NUMBERS in a listbox on a dialog form - that I pass to the main form after the dialog closes.I then ask for CASES on subsequent dialog forms and want to have drop downs for MATTER NUMBER and PATENT NUMBERS that "have the suggestions" of what was entered in those list boxes earlier.So - I've been using DATASOURCE for binding to datatables and thought to myself - heh - I can probably set the DATASOURCE of the DROPDOWNS - and it works!

I have two tables "Person" and "Alias" in a one to many relationship. I have a DGV for "Person" and want to use a combobox for the Aliases. I also have a textbox and a button for the user to type the alias name and click the button to add the alias name to the combobox and update the dataset. I keep getting the "Items collection cannot be modified when the DataSource property is set." Error. But if i use a DGV instead of a combobox for aliases, I have no errors and everything works fine. If I remove the datasource property for the combobox it will not get populated with the data already entered, so how, or can I, set it up where the combobox gets populated when the form loads and able to add items to the combobox????
View 1 RepliesI am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
