I have a DataGridView on a form in VB.NET, that is being populated from a SQL table dataset by giving criteria from a previous form. I have 6 columns in the dataset, of which the last column should be combo box column containing items "Done" and "Pending". How do I make this bound column to a combo box column and display the value as well as the alternate item too in the combo box?
View 1 Repliesis there a way to set a single cell as a combo box? it looks to me that you can only set the whole column.

I'm trying to bind data to a combo box but it does not appear to be working. I've setup the DataSet and the DataSetBindingSource and all this appears to be working, within the form design I can expand the little arrow in the ComboBox control and preview the data. This appears to be working but when the application is run, nothing appears in the drop down box.
I have the following code in place:
Code:
cmbSelectCompany.DataSource = ContactsDBDataSet.Company()
cmbSelectCompany.DisplayMember = "CompanyName"
cmbSelectCompany.ValueMember = "CompanyName"

I'm fairly new to visual basic and have a problem that is probably quite easy to solve yet I have been unable to do it so far and am about at wits end.I have an access database with a table that contains a list of cities and states. what i would like to do is to populate a combo box on a vb form with a list of the states in the states column. the query that i have is as follows:
SELECT DISTINCT State from Cities I have previewed the data in the dataset designer and it works, i just can't figure out how to make it fill the combo box. i initially created a table with just all of the states and then used a binding source and table adapter to bind it to the combo box, but if I'm able to figure this out this would help with my application going forward
i am new with visual studio 2008 and basic I have a combobox1 and combobox2 that are representing cities Combobox1 represents departure city and combobox2 destination city.Now i have a combobox3 that i want to load when i click it and run this sql query:
SELECT time_departure
FROM routes
WHERE (departure = Combobox1.value) AND (destination = Combobox2.value)
so when running the .exe of the application ,after selecting departure and destination ,when i click on the combobox3 ("hours") it will generate the results of the upper sql query as options to select.All i need is the code between this:Private Sub ComboBox3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox3.Click End Sub

View 2 RepliesI am writing a school project in VB2005 and am trying to hook up a second combo box that gets its information of what to display from the first combo box. My application is where a student takes a "test" but they can choose what instructor they want in the first combo box. From there, they choose from a test of what each instructor offers in the second combo box. As of right now, my first combo box works great and my second combo box has nothing in it. Just a note, when I debug, it shows my iUserID value as 0.

I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.
I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.
I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

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.

Below is the code to create a single Editable ComboBox column in a DataGridView on a form. I believe I have follwed the instructions to allow the user to input new values other than those in the list, however if you create a new project and add a button and a DataGridView control onto the form, then copy and paste this code and run the program, you will find that you cannot type any character in the edit box other then characters that exist in the list and only 1 character will be displayed at a time. I have set the Autocomplete value to 'False' and setting it to 'True' at least allows me to type more than 1 character but still not any strings that don't exist in the list.You can even remark out or not use the entire Call Validating sub routine to see the issue of not being able to type in the cell.

View 4 RepliesI have an unbound datagridview control whose first column is a combo box This contains a list of part numbers.I am having some problems with the datagridview automtically adding a new row when the combo box item is selected.If I select an entry from the data by typing in part number in full in the first row and pressing tab or enter then I get a new row created. No problems.However, if I then START typing a part number in the second row AND click on the part number in the list that is suggested then I DO NOT get a new row.However, if, on the first row I START typing a part number AND click on the part number in the list that is suggested I DO get a new row.

I am building a simple GUI to view data within a database. I am getting stuck when it comes to filtering data. I have followed Beth Massi's video entitled How Do I: Filter data on the client?
However my datagridview will not filter, it simply moves the highlighted cell down to the location of the item selected in the combo box. The items in the combo box are also repeated as opposed to grouped by what they they are called, for instance I have a column called region and every cell contains the text "West" and the combo box just shows a list of all the cells as opposed to just one.I followed the video several times and every time this happens. Even with a new project. Could it be because my data isnt a table but a query of several tables? I can filter on this data in excel and access easily.
