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!

Regards,
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

Hi, I have:
1) Telerik 2013 Q2 SP1;
2) Entity Framework DB (Linq to MySql);
3) Simple table: FirstName(NotNull),  LastName(NotNull), Date(Null).
4) Checked for NULL (in MySQL DB and in my Project), i.e. both properties must be NotNull;
5) Made a row validation (it's working, but when I press ESC and then trying to edit another row => the TargetInvocationException fires or smth similar in files such as Cell....cs, Gridview.....cs - I even don't have it);
The question is how to prevent this?
Code:

We have a requirement to display, along with other columns, a cumulative value column within the RadGridView.  To do this we attach a behavior to the RadGridView.  The relevant code from the behavior is this:


The basic idea of the above code is that on RowEndEdit and on DataLoaded the cumulativelength value is recalculated.

Everything works as expected when the user selects another row after editing a row (i.e. the cumulative length is updated).  However when the user clicks on anywhere else in the UI an ArgumentNullException is thrown (the message is 'Value cannot be null').  The Stack trace is:


I have tracked this down to the call to Rebind() on the RowEditEnded.

Note we are trying to use Rebind here instead of just raising PropertyChanged event from component.TotalLength as we are not in control of that library.

Hi,

I'd like to customize schedule view control so Day view looks like the attached picture. Do you think is possible to reach the desired look?

Thanks.
