Combobox DisplayMembertPath Setted : Never change SelectedItem

Posted By:      Posted Date: September 20, 2010    Points: 0   Category :WPF


I begin with WPF and binding. In my project, i have one Combobox which is binded (ItemsSource) to an ObservableCollection<Organization> (dependency property in MainWindow code-behind).

My class Organization contains a property called "Name" and i want to display it in items, so i set DisplayMembertPath to "Name".

But when i do that, if i change the item in the combobox, the item doesn't change instead of code-behind side, the SelectedItem changes.

I tried to use a DataTemplate with a TextBlock binded to the Name property, i have the same issue.


Here my code-behind (MainWindow.xaml.cs) :


public ObservableCollection<Organization> OrganizationCollection
   get { return (ObservableCollection<Organization>)GetValue(OrganizationCollectionProperty); }
   set { SetValue(OrganizationCollectionProperty, value); }
  public static readonly DependencyProperty OrganizationCollectionProperty =

How to Bind ListBox to ComboBox's SelectedItem

I have a ComboBox bound to a list of custom objects (Person). Each Person has a Friends collection. I want a ListBox below the ComboBox to contain a list of Friends depending on the Person selected in the ComboBox above it.   Something like: <ComboBox x:Name="MyComboBox" ItemsSource="{Binding People}"/> <ListBox ItemsSource="{Binding Element=MyComboBox, Path=SelectedItem.Friends}"/>   It doesn't work (null reference, I'm assuming because the SelectedItem.Friends is the wrong syntax.   Any pointers?

How to Localize Windows Forms and Change the Language at Runtime

Localization is the process of customizing your application to a particular language, culture or locale. Visual Studio provides support for localizing Windows Forms with much ease. In this article, we will see how to localize windows forms and give the user the ability to change to his preferred language at runtime.
When you run a localized application, the appearance is determined by two culture values. The UICulture property is used to specify which resource files will be loaded for the form. The Culture property, on the other hand, determines how strings such as dates, numerals, and currency amounts are formatted.
Let us see the steps required to create a localized form. You can then expand this example and adopt the same approach for the rest of the forms in your project

Bug: Does not change column type from nvarchar to ntext


Scenario: If you create a table with a column of type nvarchar, populate it with some content and try to modify it using the WebMatrix editor, from nvarchar to ntext, it does not display any error message or warning that this is not possible. It silently saves and reverts the change, back to nvarchar. Wasted some hours on this issue as I thought my column was ntext, but in fact was still nvarchar.

Expected behavior: It should change to ntext, or if SQL CE doesn't support that, it should notify the user that no change was applied.

dynamically change column names in Crystal reports


I need to develop 3 pages.

On the first page user defines atmost 7 column names to be displayed on the report. I'm saving these names in a Sql DB table 'Columns' with Column_Nm and Column_ID as Table columns.

On the second page I'm retrieving column_Nm from the table and displaying them on the page so that the user enters the data. This data is saved in another table 'Summary' with the Columns column1 through column7.

on the 3rd page I need to show a report of 'Summary' table.

How do I dynamically replace column1 through column7 names with that of 'Column_Nm' on the report?

Any help/suggestions would be appreciated.
