Shorten Selected Value In ComboBox DropDown List For Display
Feb 21, 2010I have a combo box that has a drop down list with long values in the drop down
Ex:
LB - Pounds
GR - Grams
When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows
LB - Pounds
GR - Grams
When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

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.

Application :: Display A Message To The User Whilst The Application Is Starting Up?
Nov 4, 2010I have recently created an application where a lot of data is loaded into objects when the application starts up, and other data as it is required. For example if the user requests the catalogue page then it will load all the top level category data into objects of type Category. This will then stay there to be used by other users (who will therefore not have to load this data into objects) and can be altered by admin if they happen to login during the same application instance. I know this is not the most efficient solution, as pointed out below, but it works and the page load, at the moment, is not too long. It is very quick if most of the required data is already loaded into objects. It is also tailored to the business' needs - unlike other techniques such as Linq-to-SQL.
View 1 RepliesDisplay An Amortization Table To Display The List After Doing The Calculation?
Oct 19, 2009i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

Populating DataGridView ComboBox Column During Runtime?
Nov 16, 2009I've got a window with multiple datagridviews. Each with data from a separate dataTable. All of which are part of the same DataSet. There are a couple of places where one DataTable has a field joined with the lookup dataTable from the dataset. For example a lookup table for LugSizes has a field called LugSize that is also it's primary key. Another table called Device Terminations has a field called LugSize to which the user can only select those values from the LugSize lookup table. I thought it would be as simple as using the Items.Add method for the combobox column whenever a new lookup table row was added to its own datagridview. Unfortunately, when I try to initially clear the items list, the data error event is triggered for every row.
Here's a sample of my code if it helps:

Private Sub FillLugSizeComboBox()

If colDTLugSize.Items.Count > 0 Then colDTLugSize.Items.Clear()
