Hello,

I've extended the RadDocking and I want to entend the RadPane too.
How can I set the RadDocking to create the CustomRadPane instead RadPane?
(In RadTabControl I've overrided the GetContainerForItemOverride in order to create CustomTabItem)

Best Regards

Hello Again;

I've recently hit up against another wall, in an attempt to use FluidContentControl within my TileViewItems I seem to lose data binding, charts that worked outside the control's properties no longer receive data, and same for data grids, I'm not sure how to proceed. The following is an example of my xaml (the small is meant to be 'blank' while the medium and large share the same content since I was experimenting with the controls), the chart is tied to an observable collection of objects each of which has an observable collection of 'dates' and 'decimal values' for which to populate the chart.


Your assistance is appreciated.

Hi,

I have bound to a TreeListView a collection of instances that raise the PropertyChanged from a thread that is not the main UI thread (the event is raised from a FileSystemWatcher event). When PropertyChanged is risen I meet the following exception:

InvalidOperationException was unhandled: The calling thread cannot access this object because a different thread owns it.

It really surprised me because I've previously bound other telerik WPF controls in an analogue situation and they worked flawlessly. Having a peek on GridViewRow.BeginProcessDataItemProperty I've noticed that it makes a call through the Dispatcher (which should avoid the exception) but the call to retrieve the dataItem for the row is outside the Dispatcher.BeginInvoke and that's (I pressume) the cause of the exception.

I don't know if this is intended behaviour or just a little bug but any feedback would be greatly appreciated.

Thanks in advance.

In WinForms there is (or was?) an attribute "[PasswordPropertyText(true)]" for displaying string properties as "*****" or something like that. How can I achieve this with WPF PropertyGrid?

Hi, I have a RadPropertyGrid with a combination of predefined and auto-generated properties organized in groups. I'm trying to implement a feature that remembers expanded/collapsed state of each group.
There's no problem with saving those states, a simple foreach on GroupDefinitions collection with all the groups is sufficient when a view is closing. But I can't find an event to subscribe to on the RadPropertyGrid when the view is being generated and GroupDefinitions collection is not empty. I have tried Loaded, Grouped, IsVisibleChanged and many more but no luck so far. Only if I pause an application when the view is already showed I can verify, that GroupDefinitions collection is indeed not empty. Maybe there's something I've missed, so I would appreciate any help. Thanks!

Hello,
Is there any reason why the dropdown would not have a Border?
Thanks in advance,

Hi,

I need the following changes to be applied for my chart.

Hello there,

is it possible to access a second SplitContainer in MVVM pattern in the ViewModel which is not the DocumentHost and add new Panes to it ? I have 2 Panes to search for Documents in a SplitContainer and want to re-add them to it in case that they have been closed by the user. The first SplitContainer contains the searchresults, which are editable, this is why that one is the DocumentHost. I can access the RadDocking in the ViewModel, which is passed to it as a CommandParameter. Thank you for your help!

Achim

Hi,

I am executing sql queries that are returning over 100,000 rows.  The grid visualization handles these large results easily.  From what I can gather the rows visible on screen are in memory and the rest are in some kind of cache.  I am saving the results that I set in itemssource for future review where the client does not have access to the database. I want to provide a result viewer where the client can drill down on very large data sets using the excellent adhoc filtering capabilities of the grid   The major problem that I am having is the amount of time it takes to serialize and deserialize and sometimes getting out of memory.  Since the grids UI virtualization capabilities must have dealt with these issues in some form I was hoping that you could provide me with some ideas on how to handle the serialization problem.

The following shows the coding to get the data. clientData.Result is what needs to be serialized and deserialized.  As you can see this is generic code to handle any resultset.  

clientData.Result = new ObservableCollection<dynamic>()

while (dataReader.Read())
{
  Dictionary<string, object> clientRow = new Dictionary<string, object>();

         for (int i = 0; i < dataReader.FieldCount; i++)
         {
             string myKey = clientData.ColumnInfo[i].UniqueColumnName;
             object myValue = null;

             if (DBNull.Value != dataReader[i] && clientData.ColumnInfo[i].ProviderSpecificDataType != "Microsoft.SqlServer.Types.SqlHierarchyId")
             {
myValue = dataReader[i];
             }
             clientRow.Add(myKey, myValue);
         }
clientData.Result.Add(new CloudburstUtilities.ClientRow(ToDictionary(clientRow)));
}


public static IDictionary<string, object> ToDictionary(IDictionary<string, object> row)
{
            var dict = new Dictionary<string, object>();
            foreach (KeyValuePair<string, object> column in row)
            {
                dict.Add(column.Key, column.Value);
            }
            return dict;
 }

Thanks
