Forms :: Binding Foreign Key To Combobox
Feb 24, 2010[code...]
On my first form, I have a combobox that is bound to the Locations table and displays all the different locations. Once a location is selected, a 2nd form is loaded which has textboxes which are also bound to the Locations table and are populated with the corresponding data.
Here's my issue: on the 2nd form, I have combobox that is bound to the Offices table. Currently, when this form loads all the available offices, displaying with the first office in the list. I need it to populate with the correct office based on the selection made on the combobox on the first form. I guess what I'm asking is, how does one bind a combobox to a foreign key b/c it is the foreign key, office_refnbr, from the Locations table that needs to display in the Office combobox.
I've tried a variety of bindings, including:[code...]
Binding To A Combobox?
Jul 17, 2009I am trying to add 2 databindings to a combobox. 1 will bind to the text, andthe other one will bind to the selectedvalue. However, I am only able to add one databinding to the combobox.
cmdCustomerID.DataBindings.Add(
"Text", TblCustomerBindingSource, "strCustomerID", True)
cmbCustomerID.DataBindings.Add(
"SelectedValue", TblCustomerBindingSource, "idxCustomer", True)
This is what I have done. Only the selectedValue DataBindings.Add is being captured.

Asp.net - Gridview Binding With Combobox's In Header
Jul 27, 2010how one might go about binding to a gridview in ASP.Net 4 in a scenario where the first row of my gridview should be the headers, the second should be a combobox for each column and the third is the beginning of my actual datasource.
If you can imagine what I am trying to achieve is an ability to create a binding between each column in the datagrid and another datasource. This binding is created by the user selecting a value in the comboboxes. However no matter what I try I cant seem to achieve this.
HeaderText1 | HeaderText2 | HeaderText3
ComboBox1 | ComboBox2 | ComboBox3
DataRow1 | DataRow1 | DataRow1
DataRow2 | DataRow2 | DataRow2
DataRow3 | DataRow3 | DataRow3
Binding A Combobox In A Datagridview To A New Table?
Apr 29, 2012I have set up at DataGridView "cdgvExp" for data entry. cdgvExp.Datasource = ExpTab. The datagridview can accept new rows according to how many entries there are. I will then use the data in ExpTab. The Fourth colum is called "Lot" and is a combobox in the datagridview. The goal is to have the Combobox in the fourth column have the datasource be LotTab which is populated according to other choices in the form. I am hunting for something that would work like an independant combobox like cbLots.datasource = LotsTab
How do I dynamically set the Datasource and Datamember of a combobox that is already set up in a datagridview?

ComboBox - Binding Items To Objects
Aug 24, 2011VS2008 targeting .Net 3.5x. I have a combobox with a datasource and display member set, and when I run the project, I see the items. I am also binding the selected item to another object which contains the item upon which I want to select. I have verified that both the bound object and its underlying data contain the value I expect. The problem is that I cannot get it to select the correct item - it only ever selects the first item in the list.
View 8 RepliesComboBox - Looping Through Binding Sources
Dec 3, 2009I can loop through comboboxes likes:
for i=0 to 5
directcast(me.controls ("combobox" & i.tostring), combobox).items.add ("Hello")
next
However, if I do the same thing with binding sources:
for i=0 to 5
directcast(me.controls ("bindingsource" & i.tostring), bindingsource).movenext()
next
It errors me saying that you can't cast binding source as a control or something (they aren't of the same type). How do I loop through binding sources?
Combobox Binding Data Conflict
Jun 17, 2011I've got a bound Combobox in a database for a lookup but when i set it up and change the data in the combo the program won't let me go and further. There is a data conflict but i don't know where. The problem is here in the combo setup:
Display member : ProductName (nvarChr(20)
Value Member : ProductID (int)
Selected Member: SelectedLookup (int)
This doesn't work. Everything is displayed in the dropdown by name but when i select a item. I can't go any further. If i change the Display member: to 'ProductID' the program works fine. but displays the ProductID where users won't understand. It's like it is trying to store the 'displayed member' Product Name instead in the Value Member 'ProductID'. if i use a list box instead the program works correctly.

Handle Binding A Combobox With Lookup Data?
Jan 19, 2009I'm wondering what a best practice is for handling this.I've got a standard vendor table - with VendorId (which is PK, numeric) and a field the users call SimpleId (which is usually a name - don't let the column name of SimpleId make you think it's numeric!).I've got one datatable that comes from a data adapter that looks like this. And this already changes the table in the SQL database...SqlDataAdapter("Select VendorId, SimpleId From Vendor_T", _connection)I've got this datatable on one panel of my form with a binding navigator - and you can change the SimpleId for a vendor with this.

View 2 RepliesData Binding - Databinding A List (in An Object) To A Combobox In .net?
Jan 11, 2010VB 2008 .NET 3.5. I have a custom "Shipment" object that contains a list of "ShippingRate" objects. This list of "ShippingRates" is accessible through a property "Shipment.PossibleShippingRates." That property simply returns a copy of the list of "ShippingRate" for that particular Shipment.
My UI layer receives a list of "Shipment" objects from the BLL. This list is databound to a datagridview, and shows details relevant to the Shipment such as Shipping Address, etc.
I want to bind the "Shipment.PossibleShippingRates" property to a combobox, such that when the user changes the grid row, the combobox reflects the "PossibleShippingRates" for that "Shipment."
In addition, I need a way to store the "ShippingRate" they selected from the combobox for later use.
I have tried a few ideas, but none of them work properly.

I want to store only the code there.In the second table's entry form, I am putting a combobox.
