Getting DB Column Info By Value In Combobox?
Feb 17, 2009
I finally got my last project done and Im updating it and making it more efficient. So instead of DGV to list users what Ive done is using a combobox to list the agents names in the database. I got that part done and I have that table as the datasource for the combox and that part works fine. However Im wanting when they select the Name from the combox it gets the values from the columns and displays them in the appropiate area. Ive tried like SELECT PhoneID FROM agents WHERE Agentname =" & comboname.text, but I cant get it to work that way.

im having problems with the project i was assign, so im supposed to make like a retail store POS, where i look for the articule and add how much did they take and the price.
So this is the main window is attached to this post [TEX]MAIN.JPG[/TEX], so my main problem is that im supposed to copy all the info from the top combobox and textboxes to the datagrid and so the first item it does enter it ok(well thats what i think) and when i try to enter the second item it just refresh the first item So what im expecting is that the datagrid makes several entries so that after that i can transfer all of that to a database registering the sale.
So this is the code of the button that inserts the article to the datagrid
Private Sub ACEPTAR_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ACEPTAR.Click
TEST1.Text = "Aceptada"

I am working on a desktop application, and in my application i am using combobox in 2 ways:
1. directly on the form, and
2. as a column in the grid.
This is how i have to used it in my application: whenever i am writing anything or selecting anything in my combobox it should display a floating panal containing a grid having some extra columns which help me in selcting any value in combobox.

I've been able to add my own non-bound columns to a DATAGRIDVIEW - such as a check box column.But I'm not seeing how to take a bound column and make that column be a combobox. Doesn't appear to allow that.Do I have to hide the real column and add a "fake" front-end column that I make a combobox?

I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.

I am using vb.net and winforms.I have a Form with a Bound DataGridView. On the DGV I have 5 columns with ComboBox. I am using the Editing Control Showing Even to catch the ComboBox Selection. (see code bellow).Here is the problem: After I click on a Cell with a ComboBox and make a Selection and then update the underlying cell (cell = selected value) and then click on another Row of the DGV it goes haywire. If after I update the Cell I do and EndEdit on the corresponding row of the DataSource it seems to work find.How can I determine whe corresponding Data Source row so that I can automate this? [code]

I have a datagridview containing 1st column (combobox), 2nd and 3rd column is textbox. The combobox was filled-up using datatable. My problem is on loading form, I will get a records from my database and set the value of my combobox base on those records. So if I have 5 records from my database then I should have 5 rows containing combobox in my datagridview.
I tried the code below but there's an error saying "the following exception occured in the datagridview...." but it will display correctly, but if I click in any cell that error always appear.

I have a table called PatrimoniuMasini.
What I need to do is simply copy all the values contained by column NumarMasina into Combobox1 of my Form. (i marked with red the values I need to copied into my combobox(combobox1 of my form) in fact there are 10 values I missed the last one. You can run the ddl provided below in sql server to see the output from my printscreen.
When I run the form in my combobox there are imported the values from NumarMasina column. (so this must be done in form_load callback it's sure).
Just need to import the values from column NumarMasina of table PatrimoniuMasini automatically into combobox1 when I start my application.[code]...

I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

I am using the following code for a combobox to display a series of codes depending upon the value entered in combobox1. This works fine except the column being displayed contains a 6 character field (A99999) and I would like to display only the last 5 numeric characters rather than the whole column. otherwise I shall have to add an additional field into the table which contains just the numeric part of the code.
Dim LowestVal As String
LowestVal = ComboBox1.Text & "00000"
