Re: How to attach WPF controls when maximaize the window ? - WPF Discussion Boards

I would be tempted to do something like this:

<DataTemplate x:Key="MyTemplate">
  <Grid>
    <Grid.RowDefinitions>
      <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
      <ColumnDefinition/>
      <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <Image Grid.Column=1 Width="{Binding myImage.Width}" Height="{Binding myImage.Height}" Source="{Binding myImage}" />
    <TextBlock Width="Auto" Grid.Column="1" 
      Text="{Binding MyTextItem}" />
  </Grid>
</DataTemplate>

Then, your listbox would look like this:

<ListBox Padding="3" HorizontalAlignment="Left" Width="Auto" 
  ItemTemplate="{DynamicResource MyTemplate}" 
  ItemsSource="{Binding Mode=Default, Source={StaticResource MyDataSource}}" 
  VerticalAlignment="Top" Height="Auto"/>

Re: Adding images to the listboxitems in the WPF Listbox control

Hi Pete,
Thanx for the reply.
My actual requirement is to load the listbox with ToolboxItems. Each ToolboxItem has its own image which i want to associate with the listboxitem when i create a new listboxitem. I tried multiple ways of doing it programatically but unable to get the desired result.

Without using the xaml file how can i add items to the listbox programatically. One of the ways is setting the ItemsSource property to collection containing the items. I could populate a Treeview just by creating new TreeviewItems in the code and adding them to the Treeview.But the same did not happen incase of Listbox, am I missing anything?

Also, I am unable to group items within the listbox, could you please suggest how i can acheive this?

Thanx in adv.

Hi,

Also, using the DataTemplate given above I am not able to view any image on the Listboxitem. And sometime a XamlParseException is thrown at runtime, which is as follows

connot convert string in attribute 'Source' to object of type 'System.Windows.Media.ImageSource'

Any idea what am I missing? Is it that I cannot load a Bitmap image on the ListBoxItem??

Accessing template member!

I have a template and would like to access a UIElement. Because it is a template, it is not an object unless it is a static object. How can I create a static object in a template? The x:Name=”someName” are only to access inside template NOT outside. So we get an error when we try to access from a class. i.e. in constructor I can’t access someName. This also means that I cannot write a function when there is a change.
How this can be done?
Best regards

Silverlight images not appearing in Firefox (solved)

Working through this... just completed part 3.

Accessing the ASP.NET Authentication, Profile and Role Service in Silverlight[^]

I can't get the images to appear in Firefox but I can in IE and Google Chrome - despite the fact that the latter is not "officially" supported. ???

Any ideas for things to tweak in Firefox?

Update: It now works as of this morning - no code changes. Must have been a caching issue.

How to generate items inside a Panel using WPF DataBinding?

Moim Hossain6-Feb-09 2:39

6-Feb-09 2:39

Can any one tell me, if I need to populate the items of a Panel dynamically using Binding, how can I do so?
A panel has got a Children property, unlike other collection control ListView, Listbox that offers a property named ItemsSource or stuffs like that. How can i make this thing work for a panel.

To clarify the question- How to bind the items displayed inside a FishEyePanel ..or is it possible at all?

usually, What I can do is

<stackpanel>

however, I want to generate the number of button using Binding...is it possible?

What I would do here is put a ListView inside your panel, and then generate the buttons inside ListView Items.

Forms Authentication

VisualLive5-Feb-09 21:20

5-Feb-09 21:20

Hi,
i need to create a software (about restaurant,hotel,etc..etc..),
an important request i received from my manager is to create a Forms Authentication with many different Login and Passwords where each user will get a different privilege to restrict the access.
An example:

- Login = guest ...can only access to the software without delete,add or edit the data.

- Login = adminstrator ... can do everything .

- Login = employee 01 ... can access to the software but can delete,add and edit just some (specific) data.

- Login = employee 02 .... can access to the software but can delete,add and edit just some (specific) data.

..... and so on ...

This software will be used in 5 different department in my office so each department will have different privilege/permission to access in the software.

Now i have not a clear idea to develop this feature ,never i made it as my knowledge are poor.
I will use SqlServer 2005 for the database ,Linq toSql and Wpf(interface) of course so i thought to create a table with SqlServer as follow:

CREATE TABLE [dbo].[TblLogin] (
[Name] [varchar] (30) ,
[username] [varchar] (20),
[password] [varchar] (20) ,
[Email] [varchar] (50) ,
[Roles] [varchar] (50)
)
GO

but after i get stuck i don't know how go ahead Frown | :(

If you have any idea/suggestion let me know it will be so useful for me,i'm available to learn ...i have a lot of thing to learn .

Have a good job.

Nice Regards,

Bye

Pete O'Hanlon5-Feb-09 22:37

Well, you could always use the MembershipProvider and RolesProvider classes. To use these, you need to add the relevant tables into SQL Server (added by the command aspnet_regsql[^]). Then, you need to add a System.Web entry into your config file, and add the MembershipProvider and RoleProvider sections in here. That's it - you now have access to a role mechanism. It's up to you to provide the login screen and admin screens, but that should be fairly trivial.

for my poor knowledge never i used a System.Web in past time so i have some question to understand better what i need to do but before to post my question do you have some link to show me so i can ask not foolish question.

Thanks my friend Smile | :)

Here's a sample of what would go in your config file:

<system.web>
   <membership defaultProvider="AspNetSqlProvider" />
   <roleManager enabled="true" defaultProvider="AspNetSqlProvider" />
</system.web>
<connectionStrings>
   <remove name="LocalSqlServer" />
   <add name="LocalSqlServer" connectionString="
      data source=(local);Integrated Security=SSPI;
      Initial Catalog=aspnetdb" />
</connectionStrings>

I tried your advice it is right , now i have the aspnetdb.mdf in my WPF project.
Sincerily i have not experience about Roles and MembershipProvider so i ask you if you have some link where learn some step to go ahead ...

Thanks a lot . Smile | :)

Have a nice wake up.

If you can wait a couple of days, I'm writing a RoleManager in WPF application that I will be posting up (possibly as an article - or possibly on my blog), which will provide a fairly complete implementation that demonstrates how to use Roles and the Membership API, especially with regards to the MVVM pattern. Trust me - all becomes clear when you see the code.

If you can't wait that long, you can get some ideas from here[^] and here[^] (note you need to add a reference to System.Web to your application to get this to work).
