Hi,
I'm having issues with DataBinding. I have a Form with two data bound comboboxes on it. When you select something in one combobox I may {or may not} want to change the selected item in the other combobox. For reasons beyond the scope of this post I need to change the second comboboxe's selected index from within a ColumnChanging event handler. So, inside a ColumnChanging event handler I change the value of the column that is bound to...

I'm writing what should be a very simple app against an Oracle database. The
app has a number of user controls, any one of which is loaded into a main
display page using the loadControl method, depending on which menu item a
user selects. Each of these controls follows the same basic pattern: Get a
dataset from the database and then display the results using basic
databinding.
Everything works fine except that I'll occaisionally get an...

Hi,
I have a UserControl containing some controls of which one is a ComboBox.
All the InternalControls are Private and some are allowed to be accessed through Public Methods.
One of the things I would like to do (of course) is set the DataBindings.
Something clearly is wrong with the approach I use, because I can't set the Properties in the Designer, the DataSource-Property appears like 'ReadOnly', there is no "dropdown" with the list from...

Hi all,
I may be missing something with how databinding works but I have bound a
datasource to a control and everything is great, the control updates to
reflect the state of my datasource when I update the datasource - awesome,
but I have an issue with updating from a different thread.
Here is my datasource, a person class that raises the PropertyChanged event:
class Person : INotifyPropertyChanged

Hi
I have a very simple configuration of the GridView with paging and sorting.
When I do a postback the DataBinding event fires twice - in both the
ProcessPostData and PreRender stages of the page life cycle.
In this example the event fires twice when a) GridView EnableViewState=False
and any image type control in the <columns/> element. When either
EnableViewState is set to true or the image button is removed, the event
fires once....

Hi,
I am trying to bind the selected value of a databound dropdown box in a
databound gridview control to the value being displayed in the template
column the dropdown box has been added to. Both the grid and the dropdown
box are retrieving and displaying data fine, I just cant bind the two
together.
I followed the instructions in the help document called 'Walkthrough:

I've spent loads of time Googling to try to work this one out and I'm
sure it's something obvious.
I get an InvalidOperationException reading "Databinding methods such as
Eval(), XPath(), and Bind() can only be used in the context of a
databound control" when I start my page. Unless I'm missing something
obvious, this is *not* the same issue as the "2-way databinding
cascading lists" issue in...

Hello,
I have a problem to use databinding with my business layer classes. My
data class does not have simple properties (string, int or datetime),
instead, all my properties are objects of the generic type Field<T>
(see sample code).
public class Employee
{
public Field<stringForename

Hello to all,
I want to know if DataBinding in asp.net 2,0 is better than to fill up the
values of the controls of the following form:
this.miControlTextBox.Text = valorParaControlTextbox;
Performance with databinding is good in asp.net 2.0 ? Would you prefer:
databinding or set value to Text property of control ?

Hey All,
I have been able to set up a databinding to a property with the following code:
<TextBox x:Name="txtTextBox" Text="{Binding Path=NameFirst, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
and in the code:
profile = context.NewProfile();
profile.NameFirst = "My Name";
txtTextBox.DataContext = profile;

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Here is the code in...
