How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done
Apr 23, 2010how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

View 7 RepliesData Binding - Update The Grid Data By Reading The Array
Apr 2, 2012Data binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
Listbox In Form That Gets Its Values From A Data Table By Data Binding
Jul 31, 2010I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

View 2 RepliesHow To Use Data Binding
Dec 12, 2010I have produced an Access database and a dataset linked to the database, and am working on a form in VB to enter data to this database. This form was produced by dragging the required fields from the data sources manager to automatically bind to the dataset.
I am attempting to use some radio buttons to allow users to select their gender on a form. I do not know how to take the results of selecting either radio button and upload the user's selection to the dataset, which would then be uploaded to the database.I also attempted to use a ListBox and ComboBox for some other fields, but they do not seem to work as they should, since when I attempted to press the handily provided "Save" button, I was provided with an error to the effect that the boxes appeared to be empty.

.net - Simple Data Binding?
Feb 4, 2011I have developed a form for Windows VB.Net that uses a number of text boxes that are indidivually bound to separate columns in a database. When one of the textboxes (let's call it XYZ.Text) is bound to the database, it prevents the data from any of the other bound text boxes to enter the database. When the binding for this one text box (XYZ.Text) is removed, then all the other text boxes work fine.

Cautious Using Data Binding In .NET?
Apr 13, 2010I just started working on a small team of .NET programmers about a month ago and recently got in a discussion with our team lead regarding why we don't use databinding at all in our code. Every time we work with a data grid, we iterate through a data table and populate the grid row by row; the code usually looks something like this:
[Code]...
Our team lead was saying that he got burned using data binding when working with Sheridan Grid controls, VB6, and ADO recordsets back in the nineties. He's not sure what the exact problem was, but he remembers that binding didn't work as expected and caused him some major problems. Since then, they haven't trusted data binding and load the data for all their controls by hand.
The reason the conversation even came up was because I found data binding to be very simple and really liked separating the data presentation (in this case, the data grid) from the in-memory data source (in this case, the data table). "Loading" the data row by row into the grid seemed to break this distinction. I also observed that with the advent of XAML in WPF and Silverlight, data-binding seems like a must-have in order to be able to cleanly wire up a designer's XAML code with your data.

View 4 RepliesData Binding In .NET With CSLA BOs?
Nov 5, 2009I am having quite an issue with data bindings in .NET.Some background information, my business object tier is using CSLA v1.0.And _clientObj is passed in as a parameter as a business object that inherits CSLA.BusinessBase Here is the code segment:
Dim nextClient As New ComboBox With { _
.Name = "txtClientAtt" & (ClientBoxes.Count + 1).ToString(), _
.DisplayMember = "FullNameAndID", .ValueMember = "ClientID", _
.Tag = _clientObj}

That debug statement does indeed get reached if _clientObj is a pre-existing object with an assigned ID value. How is that possible? I was assuming that adding the data binding should immediately set the .SelectedValue property of the ComboBox if the DataSource object has an initial value.

The missing link between them is a BindingSource component.Everything works fine, i.e., the DataRepeater displays list items correctly, and I can add and delete items, even change using the TextBoxes on the DataRepeater.
The problem is that when I change the value of an item in the code, it doesn't get reflected on the DataRepeater. Only when I click a button on the form which executes this code:myBindingSource.ResetBindings(False)
