I'm currently working on a project that has different windows opened up in multiple threads. There seems to be a problem with commands running in all but the first thread that is created with a RadDocking element in it.

Within each thread, a new window is created, with a RadDocing, RadSplitContainer, RadPaneGroup and a single RadPane. The window is then displayed. When you click on the PaneHeader in any window other than the first thread that is opened, the application immediately throws a threading exception: System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.

This exception occurs even when we have no code other than starting the threads. Has anyone else had this problem? Is there any way to fix this problem?

Thanks,
Daniel

Hi.
I'm not sure if im doing something wrong, but assuming this example:
http://demos.telerik.com/silverlight/#GridView/Performance
with 1000000 rows, 5 columns.
I need to load 2500 records with 8 to 10 columns and doing it like:

1st attempt to load data: using class product:

 using (SqlConnection conn = new SqlConnection(cString.c_String))
            {
                conn.Open();
SqlCommand cmd = new SqlCommand(sqlCommand, conn);
                rdr = cmd.ExecuteReader();
                while (rdr.Read())
{
-- Product p =new Product {.....};
myGrid.Add(p);
}

Second attempt:
                 SqlDataAdapter sd = new SqlDataAdapter(new SqlCommand(sqlCommand, conn));
                 DataTable dt = new DataTable();
                 sd.Fill(dt);
                dg.ItemsSource = dt.DefaultView;


Second is little bit faster i guess, but still tooks much time to load.
I have also tested only window loading time and it took ~1sec to load (only window, with listview with items from db)
Unfortunately with gridView it tooks 5 to 10 sec.

Question is:
Is there any way to (for example) load only first 50 records, and when i scroll down load more?
Or maybe there's example for gridView (WPF!) paging ?


Thanks for answer,
Adam.

hiwa

I have an wpf page with radgridview control and some radmaskednumericinput controls.the question is  whille Selection changed event of radgridview of every row i need to enter new data radmaskednumericinput control on every row and the data should not change till closing the page .

I found this article without answer. I have the same problem can anybody help me?

I am using Telerik's WPF controls. In particular the DataForm control. I am trying to bind it to an object that has the following make up.

public class FrequencyMap : BindableBase
{
    private Guid id;

    public Guid ID
    {
        get { return id; }
        set
        {
            id = value;
            OnPropertyChanged();
        }
    }

    private string procedureCodeId;

    public string ProcedureCodeId
    {
        get { return procedureCodeId; }
        set
        {
            procedureCodeId = value;
            OnPropertyChanged();
        }
    }

    private FrequencyChoice frequency;

    public FrequencyChoice Frequency
    {
        get { return frequency; }
        set
        {
            frequency = value;
            OnPropertyChanged();
        }
    }

    private DateTime effectiveDate;

    public DateTime EffectiveDate
    {
        get { return effectiveDate; }
        set
        {
            effectiveDate = value;
            OnPropertyChanged();
        }
    }

    private DateTime? terminateDate;

    public DateTime? TerminateDate
    {
        get { return terminateDate; }
        set
        {
            terminateDate = value;
            OnPropertyChanged();
        }
    }
}

and then the FrequencyChoice object looks like this:

    public class FrequencyChoice : BindableBase
{
    private int id;

    private string modifiedUser;

    public int ID
    {
        get { return id; }
        set
        {
            id = value; OnPropertyChanged();
        }
    }

    private string code;

    public string Code
    {
        get { return code; }
        set
        {
            code = value; OnPropertyChanged();
        }
    }

    private string name;

    public string Name
    {
        get { return name; }
        set
        {
            name = value; OnPropertyChanged();
        }
    }

    private string description;

    public string Description
    {
        get { return description; }
        set
        {
            description = value; OnPropertyChanged();
        }
    }

    private string calculationDescription;

    public string CalculationDescription
    {
        get { return calculationDescription; }
        set
        {
            calculationDescription = value; OnPropertyChanged();
        }
    }

    private DateTime inactiveDate;

    public DateTime InactiveDate
    {
        get { return inactiveDate; }
        set
        {
            inactiveDate = value; OnPropertyChanged();
        }
    }

    public string ModifiedUser
    {
        get
        {
            return this.modifiedUser;
        }
        set
        {
            this.modifiedUser = value;
            OnPropertyChanged();
        }
    }

}

This works quite well except for the Frequency property. How do I get that to work properly(I need name property to be in drop down list box for choose). Do I have to use an Enum like this article? Data Forms in your XAML If so how would I link the two?

Thank you for your help.

I am raising this concern as the Context Menu present in WPF does not work for web browser control.
Does the RadContextMenu help us in achieving custum context menu in WPF web browser control?

Telerik,

I have a WPF RadGridView that allows filtering and grouping of columns.  After grouping a column, I no longer see the filter icon, nor can I access the filtering of that grouped column.  I would like to see the same auto-filtering icon/functionality on the grouped column as the non-grouped columns.  How can I accomplish this task?

I have included a picture of my scenario.  There is a column on my grid with the title "From Plant" that is filterable and groupable.  Before grouping, I placed a filter on the column.  After applying the filter, I grouped the column.  Problem:  I don't see the filter icon after grouping "From Plant", nor can I access the filter popup.

Thanks,

Hi everyone,

I'm using the RadGridview component to display some data.
This grid is using the self-reference feature, some lines have children displayed in rows détails.

I added a screenshot example in attachment to expose my problem :
- The ID line 5 have 2 children in diferent cities (Paris and Bordeaux) ;
- I want to display (automatically via XAML) in the cell of the parent all children values for the column City, like this : "Paris, Bordeaux".

Is it possible ? If yes, how to do ?

Thanks for your help !

Guillaume

When selecting a node, a dashed border is painted around it. How can I customize this border?

Hi there

I've a usercontrol with a gridview that is part of a Radpane. Now I want to disable touch scrolling in a specific situation. 
Is it possible to disable scrolling with your finger on a touchdevice? I tried Scrollviewer.panningmode="None", but this did not work. I'm using the latest version of the WPF Trial.

My gridview XAML code:


Thanks in advance!
