Here's my situation:

1. an MVVM pattern is used on the client
2. the View has a readonly RadGridView with sorting and paging through the RadDataPager
3. the ViewModel has a Repository, wrapping an EntityFramework ObjectContext

The GridView is binding to a collectionview from the viewmodel:

 ItemsSource="{Binding Path=dataitemscv, NotifyOnSourceUpdated=True}"

which dataitemscv is a ICollectionView

I have checked dataitemscv is updated.

The collectionchanged event did fire with action as reset

I have tried to Refresh() the collectionview in viewmodel

I have tried to Rebind the GridView in code behind

nothing will update the UI, any suggestions?

Considering this code: 


The OpenView1Command is defined in my ViewModel. How do I make the binding work? 

I need to save docking layout into a file when the application is closing and retrieve the layout at start-up.  I tried to learn it from the Docking Serialization example, my application calls OnSave on Window_Closed event and copy the stream into a file.  Since most of modules in the application are discovered by Prism and added into the RadDocking via Prism's RegionManager at start-up, so I am not sure when should I call OnLoad function to load the layout from the file.  Could you please help.  .

Another question: what different between Isolated Storage vs Save in a Stream?

Thanks!

Hi,
I use template selector because i have different objects. Everything is fine except adding new item(NewItemTemplate = null, why?).
If I click "New" button, dataform doesnt show any fields. Why dataform doesnt use in this case EditTemplate or why it doesnt have NewItemTemplateSelector as Property?

Thanks! 

Hi..
I have the following ComboBox using a data template.. I'm trying to set the default value to a selection.
When the page loads the selection is blank.
I've tried 


  // BIND
  var queryConf = from c in DC.conferences
                            orderby c.name descending
                            select c;
                        
        this.cmbConf.ItemsSource = queryConf.ToList();

// Set DEFAULT
  this.cmbConf.SelectedItem = queryConf.ToList()[1];
   this.cmbConf.Text = (queryConf.ToList()[1] as conference).name;

but the selection is still blank. !!!

I have also tried

this.cmbConf.SelectedIndex = 1;


How can I set the default value and show the values? 
What am I doing wrong.
thx again

hi ,

I am having a scenario where i want to add hyperlinks within Richtextbox dynamically from code .I want a specific tool tip as well for each hyperlinkinfo.Since there is only navigateuri property through which we can assign some key info , there is no other way to customize the tool tip information so that tool tip informtaion can be different.

I have already checked hyperlinktooltipformatstring  which will only change the navigationuri position inside the tooltip through placeholders.The basic intention is to set navigationuri some information which can be primarykey sort of text which can be processed in hyperlinkclicked event and some meaningful information as tool tip information that is different from navigationuri.

for eg: navigationuri can be some guid ( "e7c784da-a6c7-4b84-bf1c-8e2b93b9e7ab" ) and tool tip like " click to go to screen 1".
Any help appreciated in advance.

thanks

The calling thread must be STA, because many UI components require this.

Hi Team,

When ever i used grid column width as * , the width of the next column value is changing dynamically based on the content of * width Column. But the same code working nicely in RibbonBar and  Normal Window. But when the same code paste in Ribbon View BackstageItem the designing is disturbing. Please look at the below code snippet and help me.
