Forms :: Re-Bind A Combo-box By Other In Same Datagrid?
Oct 24, 2009
I've got this question while i'm searching the web for my problem.It's the same as mine ..I have a datagrid of three columns;
1. Comb-box1 : Employees' Names (DataSource : EmployeeBindingSource)
2. Comb-box2 : Coming Departure. (DataSource : DepartureBindingSource)
3. Text-box : ...............
* How can I filter or re-bind the source of the second one as the first one value changed (Both are in the same datagrid).>> So as I select an Employee I need the second one gives me just the specific departures of the desired employee.Where I have the (Employee_No) field connect the two tables related to each one.

I'm using Visual Basic 2010. I have my dataset in my program. I'm have several combo boxes on the form that I was able to bind the particular table with the information from each table to most of the combo boxes by dragging and dropping them onto the combo boxes. However, one combo box in particular must be populated by code. When a user selects, let's say "a" from one combo box, I need the next combo box to display information in certain tables only, based upon their choices in the previous combo box.

I'm trying to bind a combo box to a Access database field. I'm trying to do this with code instead of using the data sources wizard as I was told that this would be more flexible and better if distributing the finished program to other computers.
The result is that the form runs, but nothing is in the combo box.
I have also not used a dataset in my code, only a data table. Am I correct in thinking that this is plausible?

i am trying to bind the combo box through details view in vb.net but unable. i am making a login form and i want to display two values e.g usertype admin , employee in combobox but when i run the form it doesnot show me anything in combo box although i have selected the true binding source and display member but still unable. Another problem is in my form load event if i left this line written
Me.StaffTableAdapter.Fill(Me.StaffDataSet.staff)
it not only shows me the combo box values but also types in the user name and password which is saved in database. All i wana do is when the form gets loaded ..user name and password field should be bland but the user type field should show two values.

While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

I need some advice I have a bound datagrid and a bound combobox lookup on a form. What i want to do is filter the combo box so it only shows the items left that are not in the datagrid already.
I have managed to achieve this already.But when the program runs, and there are items displayed in the data grid the combo box items are now filtered.The program crashes as it can't display the combobox item as i have filtered them out. The program runs fine if the datagrid is empty (IE combobox items not filtered). But as soon as there is a record in the datagrid when i save the database and refresh the combo box the program falls over is the items it is looking for is not in the combo box items list.
What would a work around be. I have thought of a separate combo box that is hidden and use the datagrid combobox events to show it in the correct position.Just to be tedious the displayed item is not the stored item value

I have a problem trying to link my my datagrid view to my sql server stored procedure.

The @comp is supposed to be each item in the combobox list but I don't know how to do it or how to go about it
