Re: Skinnable silverlight applications

15-Nov-09 6:03

You could merged dictionaries to provide alternate "skins" for controls.
Allowing the user to change them will require some coding definitely, because
you'll need to build dictionaries at runtime and probably need a way to save
the user's preferences.

The ImplicitStyleManager can help for applying styles to controls at
runtime so you don't have to do that part manually.

The implicit style manager is probably the one I was looking for.

request error

I see the following error while connecting to a wcf service through my silverlight application.

An error occurred while trying to make a request to URI 'http://localhost:3046/Service1.svc'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details.

How are you hosting the WCF app? How are you hosting the
Silverlight app?

If the Silverlight app isn't hosted at http://localhost:3046
then you'l have a cross domain issue. That means you'll
need to provide a clientaccesspolicy.xml file at the root of
the domain the WCF service is hosted at.

Making a Service Available Across Domain Boundaries[^]

If you're hosting the WCF service in WcfSvchost.exe or self hosting,
you may need to serve up the clientaccesspolicy.xml yourself:

Enabling cross-domain calls for Silverlight apps on self-hosted web services[^]

Or you can host your WCF service in IIS[^] and just put the
clientaccesspolicy.xml at the root of the host domain.

The project/solution has no relevance here.

I mean the web hosts...WcfSvcHost...IIS....Self Hosting?

Then you'll definitely want to study the information
at the links I provided to understand the cross-domain
issue and how to deal with it.

Create a new row at the bottom of DataGrid (When User Click on Button(Out side of DataGrid))

13-Nov-09 9:23

The WcfSvcHost is for testing/debugging.

You'll probably want to consider how it will work
when the service is actually deployed. I find hosting
on IIS the easiest and most flexible.

Hi All,

I have to take the inputs as multiple entries in WPF data grid like this.

----------------------------------------------------------------------------------------------------------------------
| Select Option | Name | Age |Country | Action | Action |
----------------------------------------------------------------------------------------------------------------------
| option button | textbox | textbox | combobox | linkbutton edit/update row | linkbutton edit row |
------------------------------------------------------------------------------------------------------------

ADD Button
-----------------------------------------------
--> By clicking the ADD button i have to create a new row with new controls as in 2nd row.
--> By clicking the DELETE button in the 5th cell the corresponding row should be deleted.
--> By clicking the EDIT button in the 4th cell the corresponding row should be UPDATED(if user want)

Can I achieve this by taking WPF Data grid (WPF tool Kit Latest Build ), and how?

Or is there any other ways to achieve this?

Suggest me some URLs, Samples..etc

Many Many Thanks in Advance.

If the itemssource for the datagrid is an observablecollection,
generally all you need to do is add or remove items from the
collection and the datagrid will update appropriately.

How are you providing data to the datagrid?

Hi Mark Salsbery,

Thanks for Quick Reply,

Right now am providing data by using DataSet like

dgXXX.ItemsSource= dataSetXX.Tables[0].DefaultView;

Case 1: How to convert Data set to observablecollection..

case 2. i have some limitations, a) I am retrieving data as DataSet from Oracle11g by using Ref_cursor.

Now ... Please suggest me a way to approach.

Thanks

You should be able to use the DataTable as-is if
I remember right.

dataSetXX.Tables[0].Rows is the collection you can add/delete items
from (using DataTable.NewRow() to create new rows to insert).

dgXXX.SelectedItem should give you the DataRow selected in the datagrid.

Here's some more info: Windows Presentation Foundation Data Binding: Part 2[^]

Here's one example (see first reply): Binding a WPF listview to a DataTable[^]

An article with a little background in it: How do I bind to ADO.NET?[^]

If you can show a simple example of what you tried that
didn't work then maybe I can see what's going on...

Does anybody know of a working Weather Web Service that I can use in my WPF app? I've tried numerous ones but none seem to be available when I try to add a reference to it.

Thanks I'll try them out.

I've been trying the GlobalWeather service from WebServiceX, and I get it working to display the following in a textbox:

<?xml version="1.0" encoding="utf-16"?><CurrentWeather>
<Location>Port Elizabeth, Port E Apt, South Africa (FAPE) 33-59S 025-36E 0M</Location>
<Time>Nov 13, 2009 - 09:00 AM EST / 2009.11.13 1400 UTC</Time>
<SkyConditions> mostly cloudy</SkyConditions>
<Temperature> 68 F (20 C)</Temperature>
<DewPoint> 55 F (13 C)</DewPoint>
<RelativeHumidity> 64%</RelativeHumidity>
<Pressure> 29.91 in. Hg (1013 hPa)</Pressure>
<Status>Success</Status></CurrentWeather>

Does all web services return information in this way or not? I'm quite new to them. If yes, how can I show this data in a more understandable format e.g. in textboxes?
