View 4 RepliesChange List Of Combobox A Based On Item Chosen From Combobox B?
Jun 17, 2011I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

View 2 RepliesVS 2010 ComboBox Dependent On Another ComboBox
Aug 22, 2011I am having issues when trying to populate a combobox that is dependent on another combobox. Populating the first combobox works as expected but attempting to set the value member or display member properties of the first combo box cause its selected index changed event to fire. That event seems to fire before the first combobox is fully loaded. The issue is then raised when trying to populate the second combo box, since it is dependent on having a valid value member to complete the dynamic sql statement, and at that point in time, there is no value member.
I can�t imagine that this is difficult but searching hasn�t yielded me any results. Should I be using a different event? What is the right way to do this?
I have a simple workaround in place - not allowing the second combo box to attempt to populate unless the first combobox has an index greater than zero but this hack is no good since it clearly prevents the user from selecting the first element in the first combo box.

Each option in the combobox has a number of public properties that need to be associated with it.When a option is selected, the user will then have two buttons that each call a different sub, the appropriate options are passed to the sub.Each option will always have the same properties required to be passed.So I'm looking at something like this.

View 3 RepliesForms :: Drop-down List Combobox?
Mar 23, 2010I have created a drop-down list box that holds 8 numbers representing a month span (3, 6, 9, 12, 15, 18, 21, 25 months). In order to prevent users from typing just anything into the text box above the combo box, I changed it to a drop-down listbox. The other requirement that I was hoping to implement was for the user to be able to type a number, after which the selection would jump to the appropriate item (i.e. the user types in '1', and the selection jumps to 12). This partially works. It will jump to 12, for example, but immediately after the user types the '1', the Selected Index event changes. The user cannot scroll down or up after typing in a number.
