Populate Text Property And Items Of Combobox Not Using Databinding?
May 12, 2010 I'm rewriting a VB6 application in VB.Net. So far I have 2 forms, frmLocations (frm1) and frmLocationInfo (frm2). frmLocations has a combobox, cboLocations, from which a selection is made and an "Ok" button is clicked, which then loads frmLocationInfo. frmLocationInfo has a series of textboxes to display info corresponding to the location that was selected - Location, Location Number, Phone, Fax, Email. There are also 3 comboboxes on frmLocationInfo - cboDepot, cboFreight, and cboDispatcher. I need their text property along with items to be populated, also with data corresponding to the initial selection made on frmLocations. I'll spare you all the difficulties I'm having w/the other comboboxes, and instead focus on cboDepot. I have gotten it to populate its text property to display the corresponding Depot, however, the items are not populating and all you see now when you click on the dropdown arrow is only the depot that shows up in the text property.
Here is the code for this portion.
frmLocationInfo
Private Sub FillDepotCombo()
Dim sql As String = "Select distinct depot.depot_name, depot.depot_refnbr, locations.site from depot inner join locations on depot.depot_refnbr =

ComboBox Event After SelectedValue Changes?
May 3, 2010I'm using VB 2008. I'm looking for a way to take the value of the combobox after the user selects the right one. The combobox is databound and in List mode allowing selection of only the items in the box. I allow autocomplete by setting:
AutoCompleteMode = SuggestAppend
AutoCompleteSource=ListItems
So the user can key in the right value and the value narrows down each time. The user can press enter or just click somewhere else to select the value. I need a way to display the value of the combo after the selection is made but not each time a user presses an additional key to narrow down the selection.

Updating Two Tables Using A Databinding From Within A Form?
May 16, 2011I have three tables Tasks, Notes & CallTypes Each item in Tasks and Notes has a relationship to CallTypes and my form edits work fine. However: Notes only belong to tasks, and when i update the note record we will need to change the CallType for the Task as well as for the Note and they could both be different.
I have the Notes working fine, but i cannot update the tasks. I have created a databindng on to a form from the datasources window. All the notes fields are ok and are working I then add the calltype field from the tasks, draged from the data sources window (i dont want all of the tasks fields, just the calltype).
The code does not through up errors, but when i save the form it only updates the notes and not the tasks.

SQL Server SELECT Stored Procedure According To Combobox.selectedvalue?
Apr 12, 2010In order to fill a datagridview according to the selectedvalue of a combobox I've tried creating a stored procedure. However, as I'm not 100% sure what I'm doing, depending on the WHERE statement at the end of my stored procedure, it either returns everything within the table or nothing at all.This is what's in my class:
Public Function GetAankoopDetails(ByRef DisplayMember As String, ByRef ValueMember As String) As DataTable
DisplayMember = "AankoopDetailsID"
ValueMember = "AankoopDetailsID"[code]....
guess it's down to the WHERE part of the stored procedure, but I need a way to pass the selectedvalue of the combobox into the @AankoopID parameter.
.net - WInforms Combobox SelectionChangeCommitted Event Doesn't Always Change SelectedValue
Mar 23, 2012I have a WinForms app built with VB.Net in VS 2010, and I'm scratching my head over the following issue.I have a form with a combobox which gets bound to a datasource when the form is loaded:
With Me.cboCompany
.DataBindings.Clear()
.DataSource = Me.m_dsBidResults.Tables("Company")
.ValueMember = "company_id"
[code].....
This seems to work fine, as long as the user doesn't switch focus to some other control and then go back to the combobox. After switching focus, if the user then changes the combobox selection to the first item in the dropdown list (SelectedIndex = 0), the SelectionChangeCommitted event fires, but the SelectedValue remains set to the previously selected value. I've verified this by adding a message box in the above event handler, displaying SelectedIndex and SelectedValue side-by-side.
'add this to SelectionChangeCommitted event handler MsgBox(String.Format("Selected Index: {0}, Selected Value: {1}", cboCompany.SelectedIndex, cboCompany.SelectedValue))
This does NOT happen if the user changes SelectedIndex to anything other than 0; everything behaves as expected. I've verified that the table I'm binding to contains unique values for company_id and company_name.Do I need to use some other event to verify that the SelectedValue has actually changed?

Nov 12, 2009I'm having an issue with getting the errorprovider to work in a database application where I have put the error provider logic in a partial class and have a combobox value change.Either I set the bindings so that it works but any navigation in the binding navigator then updates the value of that combobox on every next previous etc or it never fires until the save. So there is no way to change the errorprovider setcolumnerror string to something new with out saving on every navigation move.

How To Expose ComboBox On User Control For DataBinding

I'm trying the following code that I've cobbled together from what bits of documentation I can find but so far no joy.

Data 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.
Populate Textbox Based On ComboBox Selection Not Using Databinding
Apr 27, 2010I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:
frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
Private Sub frmLocation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
conn.Open()
[Code] .....
What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.
VS 2005 : Stop Combobox Event Firing During Databinding?
Mar 29, 2010I have the following code that populates a combobox:
With Me.ClassSelector
.DataSource = DataAccess.Utilities.ReferenceDataUtils.GetLookupTableData("Category_code_classes")
.DisplayMember = "Category_text"
.ValueMember = "category_class"
End With
However, the SelectedValueChanged event fires once when I set the datasource and again when I set the valuemember. In both instances there is a selected value, although that value was not selected by any user action, but rather because of the loading of the combo box.I don't think there's a 'SurpressEventFiring' property for the combobox, so how to you check to see if the change in the selection was a result of user action and not data loading?Perhaps I'm populating my combobox wrong?
edit: changed 'displaymember' to 'valuemember'
