update master-detail binding with a listbox and textboxes

Posted By:      Posted Date: October 07, 2010    Points: 0   Category :WPF

I have a class, for example FooBar, that is databound to a Window, displaying all kinds of good stuff. It includes an ObservableCollection<Color>, for example shadesOfPink, that displays in a ListBox. This works fine, until I want to bind 3 TextBoxes to the properties ScR, ScG, and ScB of the selected Color. They can display the properties correctly, but when the user changes a value, the Color is not updated in the ListBox until the ListBox is clicked on to change the selection. I want the Color to update as soon as the TextBox loses focus. Is there a way to do this?

I have tried binding the TextBoxes to SelectedItem and binding directly to the properties but nothing worked.

I am using C# 2010.

Master-Detail with the GridView, DetailsView and jQuery's ThickBox

One more article about grids from Matt Berseth. This time he shows how to create master-detail with the gridview, detailsview and jQuery's ThickBox. He writes:
So I thought I would check some of this out and along the way rebuild my Master-Detail with the GridView, DetailView and ModalPopup Controls and replace the ModalPopup with jQuery's ThickBox. I found it pretty interesting - read on to see how it went

This code drop is part of a smash and grab series. If you're in a rush, you can just grab this code and insert it into your application, no understanding is required. When you have some time (ya, right) you may want to review the source code.

Problem with master page and update panel (I think)



the app I am working with is made up of three nested master pages that have the following design:

The first master page ha only realize the HEADER, BODY and FOOTER divs.

The second one specialize the Body content placeholder and divide it in three more layers: NAVIGATOR, PAGE TITLE, BODY CONTENT.

The final layer specialize the BODY CONTENT in PAGE CONTENT and ACTIONS.

In one of my content pages I have (inside the PAGE CONTENT area) 

  • 1 Update Panel that contains a gridview object
  • 1 Update Panel that contains some HTML code to show in a PopupModalExtender

The PopupModalExtender can be either triggered from inside the gridView and also from a series of LinkButtons that are in the ACTIONS area.

The problem is that when the PopupModalExtender shows the FOOTER and the ACTIONS areas are not dimmed from the style I apply as background to the modal popup. An example of what I am trying to explain can be viewed in the following screenshot.

Why this is going to happen? Has anybody any suggestion on how to solve this problem?

Thanks a lot

Data binding a listbox

I'm using VS 2010 and writing a WPF application.  I have a listbox on a form that I want bound to an access database field.  In the code behind I create the usual oledb connection, command and adapter and run a query.  In debug I can see the dataset has 143 items from the database, a single column called "path".  Here's the relevant code:  oleCon.Open(); adpt.SelectCommand = oleComd; adpt.Fill(dtst,"MyTable"); MusicList.DataContext = dtst; MusicList is the listbox.  There's 143 items in the dataset.  When the form loads the listbox is empty.  Here's the xaml for the listbox: <ListBox Grid.Row="1" Height="477" HorizontalAlignment="Left" Margin="7,6,0,0" Name="MusicList" VerticalAlignment="Top" Width="310" Grid.RowSpan="2" Background="#002400" ItemsSource="{Binding Path=path, Mode=OneTime}" DataContext="{Binding}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Path=path}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> At least I know the data is present but why isn't it binding to the listbox? Thanks!

Master/Detail with Northwind (SSMA) and ASP.NET

I'm trying this example: http://www.asp.net/data-access/tutorials/master-detail-filtering-with-a-dropdownlist-cs I got it to work before, like 6-months ago.  I'm coming back to this now and I can't seem to get the example working. Do I need to create a query in SSMS and then set up my Master/Detail views off of that?  It seems like the GridView is NOT linked to the DropDownList and it seems like there is no way to link the two Objects.  Any ideas as to what I could be doing wrong? Thanks everyone!!

Insert Master/Detail data using ADO.net Transactions

Auto Binding Constraint doesn't update the UI

I needed a way to auto bind an activities inArgument to its parent activities delegateInArguments (property defined in an activity action). Picture dropping a WriteLine activity into an foreach<string> and having the foreach's argument automatically placed into the in argument of the writelines text property - binding it as it is dropped. I have created the constraint, and it works, including changing the binding to the parent or setting the property back to null if not in a parent.  My problem is that the UI doesn't reflect this.  It actually looks like it is doing nothing - I only know it works because it comes back correctly after a save and load of the workflow pattern. I'm guessing that I somehow need to refresh the model item? How do I refresh the model item from within a constraint? If it helps I have included the code for my constraint below, but note that my need is not as simple as the above example, so this does a couple of other things that don't make sense to this question. static Constraint CheckParent() { DelegateInArgument<GetTaskPermissionsActivity> element = new DelegateInArgument<GetTaskPermissionsActivity>(); DelegateInArgument<ValidationContext> context = new DelegateInArgument<ValidationContext>(); Variable<bool> result = new Variable<bool>(); Variable<

How can i do TwoWay Binding between listbox and datatable

I've bound my listbox to a datatable using the following code: Me.TasksListBox.DataContext = dt The datatemplate in the listbox is a collection of controls like textboxes and comboboxes, each of which is bound to a column in the datatable. The data loads fine in the listbox. As the users modify the data in the listbox by modifying combo boxes , textboxes of items in the listbox , i want the changes to propogate to datatable dt so i can save the values in the database. I am unable to figure out how this can be done. Thanks

Accessing master formview data from a nested detail formview?

Hi all, I would like to ask if it is possible to access data on a master FormView from a nested detail FormView. I have a main form (master) with several tabs (detail) and would like to display a label with text from main form that is hidden by the tab at the moment of editting. My asp page looks like this.<asp:FormView ID="fvwCustomer" runat="server" DataSourceID="dsCustomer" DefaultMode="Edit" DataKeyNames="CustomerID"> <EditItemTemplate> <asp:TextBox ID="CompanyTextBox" runat="server" Text='<%# Bind("Company") %>' /> <asp:FormView ID="fvwContactPerson" runat="server" DataSourceID="dsContactPerson" DefaultMode="Edit" DataKeyNames="ContactPersonID"> <EditItemTemplate> <%-- I need to get the value Company from dsCustomer --%> <asp:Label ID="CompanyTextLabel" runat="server" Text='<%# Eval("Company") %>' /> </EditItemTemplate> </asp:FormView> </EditItemTemplate> </asp:FormView>   Is it possible to get the value of the label CompanyTextLabel from CompanyTextBox using just ASP.NET expressions or something similar without writing c# code in

Listbox - Temporary suspend Data Binding

Hi. I have a listbox bound to an ADO.NET DataTable (by his DataView) thorough ItemSource property. Whenever I add a new row to DataTable, listbox reflects that change showing an empty item.

Dim bind As New Binding bind.UpdateSourceTrigger = UpdateSourceTrigger.Explicit bind.Mode = BindingMode.OneTime bind.Source = tblRaccoltePunti.DefaultView lstRaccoltePunti.SetBinding(ListBox.ItemsSourceProperty, bind) I need a way to suspend the DataBinding to manually update listbox when row is committed.
