I have a VB application that's about 95% done. As usual, it's that last 5% that's got me stymied. The program is a Bill-of-material update program that interfaces with an SAP database. The BOM's relate to custom computer configurations. By the nature of a BOM, there are many lines, with many fields to each line. The program uses a DataGridView control to present the data. It is currently working ok with manually-keyed input. However, to make it user-friendly, it needs to use ComboBox dropdowns for the various selections. Therefore, several of the DataGridView columns need to include a combo box. This is where my problem lies.
Specifically, I have two issues: (1) getting the combo-box to populate from an SQL statement, and (2) getting subsequent combo-boxes on the same line to tailor their content based on the previous combo-box. To illustrate the second issue, if the first combo-box says that this particular row deals with data storage for the computer, then the only items that should be included in the second combo box would be those that are disk drives. Obviously, the selection and content of a control on one BOM line will be completely different from those on other rows.
I am able to dynamically load a standalone ComboBox, by setting the Display, Value, and DataSource (which returns a table) properties. However, I can't seem to accomplish this when the ComboBox is embedded in a DataGridView control.
Any help would be greatly appreciated.

Is your problem to get the combo box in the DataGridView?
If this is the issue I feel the below code could help you.
After
dataadapter.fil l(dataset)
if the column name is empGrade and this is the first column for which you require the column in the grid view as combo box then
dim colempgrade as new datagridviewcom boboxcolumn
colempgrade.dat apropertyname=d ataset.tables(0 ).column(0).toS tring()
colempgrade.nam e="employee grade"
colempgrade.dat asource='use the column name or list yyou want to populate the combo
datagridview.ad d.columns(colem pgrade)
Please ignore if this not what was not required

What is the version of VB that you are using?
What is the version of VB that you are using.
.NET 2005 is the version I am talking about. I think we have datagridview from 2005 only, the earlier version had only datagrid which lacked some of the enhancements compared to that of DGV.
Please check if you are using the same version I could give you the exact code for the requirement.

I have been searching all over the web for a way to sort a DataGridView based on
the actual text being shown in a ComboBox column as opposed to the underlying
value (an ID in this case). Can anyone tell me if this is even possible, and if
so, how to do it? If this is completely impossible, how would you suggest going
about sorting a ComboBox wherein the text displayed in the column is the
client's name, and the underlying value is an ID?

I have a datagridview control, and one column is a ComboboxColumn. I
simply create a ComboboxColumn, add items to it, then add the column
to the Datagridview control.
If I were working with a simple ComboBox, I could capture an event
that fired everytime the selected item changed. Is that possible if
the DatagridView control?
I've looked at various events, but none give me what I want. For
example, the CellEndEdit event won't fire...

Hi,
I'm using vb.net express 2005 and I've got a project where I use a
datagridview with a combobox in the first column.
Depending on the value the user selects I have to set values of other
cells.
The problem is that I get the selected value when the datagridview
isn't in edit mode. First I have to select another cell.
