.net - Winforms, BindingList, BindingSource - Cannot Bind To Property/column Id
Feb 28, 2011I have the following code on a form:
Public Sub Init(ByVal SelectedItems As List(Of Cheque))
Items = New BindingList(Of Cheque)(SelectedItems )
BindingSource1.DataSource = Items
[code]....
This code gets called like so:
...
fmEdit.Init(myList)
fmEdit.Show()
All variables are populated etc, it seems to go through the DataBindings.Add ok but when the form appears I get the error about unable to bind to a property or column called Id. I tried replacing the DataBindings.Add code to use the BindingSource1 instead of Items but I get a similar error.The names of the properties in the class match that of the name in the Databindings.Add code.
UPDATE: Here is my class:
Public Class Cheque
Public Id As String
Public Status As Byte

C# - Bind Combobox To Enum List & Change Position Of Another Tables Bindingsource
Nov 23, 2011I have the following:

Unable To Run BindingSource.Filter Using A Textbox Value?
Dec 9, 2009I am using the following code to filter on a textbox value using the BindingSource.Filter function.I thought this was the right code based on my many searches.
BindingSource1.Filter = "ValueID = '%" & ValueToFilter.Text & "%'"
When do a debug, it shows the correct value which is "432360ac-ac35-4101-8d46-f2cbd5b5dc52.There are spaces in the end of this value and it is exactly the same in the SQL database with the spaces. ValueID is a column in my SQL server. It does not filter the records in my dataset.I tried replacing the ValueToFilter.Text with my actual value as shown above including the space at the end and it filters the records just fine exactly as I want it to. Although I obviously need it to work for multiple values from my SQL server.

Bind TWO Different Database Tables To ONE Textbox In VB?
Mar 20, 2011I was wondering if there is any way to bind TWO different database tables to ONE textbox in VB? I've spent the whole day going through tutorials and different webpages and I've found nothing at all on this...
Well let me try to explain what I want to do exactly: basically I have multiple buttons on 'Form 1' and a textbox on 'Form 2' asking the user to insert a value which will then go to an Access database. But here is where it gets tricky for me: IF the user presses Button 1, the Value inserted on Form 2 will go to a field in the database whereas if the user presses Button 2 to open Form 2, then the value will go to somewhere else and so on.
This would be easy to do if I was to create multiple forms or multiple textboxes, 1 for each button but what I really need is 1 form/1 textbox that would work for all of them... [URL]

Loop Through Child - Bind Textbox To Field Of Parent Table
Mar 22, 2010First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,
Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)
But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.
