View 21 RepliesI have a dataset with a table. The table has three columns.The first column is a combo box with 6 company names loaded in it. The second column will allow my user to enter monetary values which are spending from whatever company was selected in the first column.The third column will calculate a percentage.After putting the table on my form, I would like to go through the table as the user enter the values and add the monetary values of the second column if they belong to the same company.Meaning that for example every time company A is detected in the combo box, its spendings will be added and displayed in a textbox in a different form.Every time company B is selected in the combo box, its its spendings will also be added and displayed in a textbox in a different form.and so on, and so on for all 6 companies.

i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
Me.xGeneralComboBox.Items.Add("Soda")
Me.xGeneralComboBox.Items.Add("Juice")

View 3 RepliesI have a form with 8 combo boxes and would like to disble certain combo boxes, depending on what was selected in another combo box. The reason is so the user will not have a blank return on a query. The first form I created like this worked great, no issues. This form only allows one combo box (Number_of_Lightheads) to disable any others. Below is the code I have for this Form. why the other combo boxes will not disable the ones that are called out in the code?

I have two combo boxes and I am currently using MicroSoft SQL Server to get the instance name into one combo and the databases on that instance into the other combo. I am wanting to switch to System.Data to get these values and I am able to get the instance through enumeration but am having trouble finding where to get the database name values assigned to that instance.Does anyone know the equivalent of SMO Server.databasename is in System.Data?

View 1 RepliesI'm having some weird trouble with adding a new value in a combobox.The combobox has a datasource which is a bindingsource.The combobox's list is filled from a different table through a different bindingsource. Combobox.valuemember = "ID" and Combobox.displaymember = "Description".When a user types a value in the list, I want to add the new value to the table which is the source for the list. (Which is not the problem, but I don't get that far) The problem is that when the user types a new value in the box, it totally disappears as soon as the user tabs out of the combobox. So, in the event combobox.Validating the combobox.text property (nor any other property) does not show the new typed value.

I am using a combo box on a form in vb net 2008. I would like the user to be able to either tab to the control and then select an
item OR the user could click on the combo box and then select the item.
unfortunately it fires twice when the user clicks on the control. This is before any items are selected. I have tried placing it in mouse down , focus , key down etc etc.
It does not fire twice for the enter event so I tried to use that alone, but then there is no dropping down of the combo box when the user clicks on the control. Is there a way to release the combo box enter event on the mouse click event?

View 7 RepliesI created a data grid view from the datasources list and converted 1 of the columns into a combo box. Unfortunately, the combo box isn't acting like a proper combo box. When I start typing, the combo box does not display the characters I have entered. All it does is begin looking for the entry that matches what I am typing.
This is no good for my purposes, the user needs to be able to see what they have typed. Is this how it works when in a grid? I have tried playing with a lot of the column options but nothing makes it work correctly.
How do you make the autocomplete feature on combo box in VB behave in the same way as one in VBA?
the VBA properties are as follows:
MatchStyle = fmMatchEntryComplete
MatchRequired = True
The VB properties are quite different and i havent got a satisfactory combination. I need it to suggest items from the list as i type but insist on a match with the list. However on VB forms, unlike VBA forms it doesnt show the suggestion in the combo box itself, but in a box beneath.
