I know there are some limitations on pictures, encoding and other things, but would it be possible to show an error message saying it's can't load this pdf?  99% of the files I think will work, but if a client tries to use a file that doesn't load correctly I'd like it to give an error message and say to download the file instead.

Hi,

in my project I have a method who need parameters and one of them is an object that I want the persistence stream result.
When I call my method, the PersistenceError event handler was called when I try to use the SAVE method of the PersistenceManager and I get the following french error message: Nombre de paramètres incorrects.

Here is the way I call my method:

PersistenceStorage

 

.Persist(MainGrid, ref stream, PersistenceStorage.PersistenceAction.Save, out errMsg);

 

Here is my static object with my method:

static

 

public class PersistenceStorage

 

{

static public bool Persist(object pObject, ref Stream pStream, PersistenceAction pPersistenceAction, out string pErrorMessage)

 

{

mResult =

true;

 

pErrorMessage =

string.Empty;

 

 

PersistenceManager manager = new PersistenceManager();

 

manager.PersistenceError +=

new Telerik.Windows.Persistence.Events.PersistenceErrorEventHandler(manager_PersistenceError);

 

 

try

 

{

 

if (pPersistenceAction == PersistenceAction.Load)

 

{

 

if (pObject != null && pStream != null)

 

{

pStream.Position = 0L;

manager.Load(pObject, pStream);

}

 

else

 

{

mResult =

false;

 

}

}

 

else if (pPersistenceAction == PersistenceAction.Save)

 

{

 

if (pObject != null)

 

{

pStream = manager.Save(pObject);

}

 

else

 

{

mResult =

false;

 

}

}

}

 

catch

 

{

mResult =

false;

 

}

 

finally

 

{

manager.PersistenceError -=

new Telerik.Windows.Persistence.Events.PersistenceErrorEventHandler(manager_PersistenceError);

 

pErrorMessage = mErrorMessage;

}

 

return mResult;

 

}

 

static void manager_PersistenceError(object sender, Telerik.Windows.Persistence.Events.PersistenceErrorEventArgs e)

 

{

mErrorMessage = e.Exception.Message;

mResult =

false;

 

}

 

public enum PersistenceAction { Load, Save }

 

 

static private string mErrorMessage;

 

 

static private bool mResult;

 

}

Hi

I want to be able to drop a file from the desktop on to an existing row in a RadGridView. (The event handler will then do something with the file and manipulate the data for that specific row, but that isn't relevant for this discussion.)

Can anybody shed some light on how this can be achieved? I have managed to drop a file on the the RadGridView component itsself, but that's not what I want. I need to be able to drop on a specific row (or preferably have the option to drop on the RadGridView also if it doesn't conflict).

I am finding the Telerik documentation about drag and drop (using DragDropManager) hard to figure out since some of the examples just don't work (http://www.telerik.com/help/wpf/dragdropmanager-getting-started.html) and many of the example projects referred to in prior forum solutions seem to use the RadDragAndDropManager which I understand is soon to be obsoleted.

Anybody? 

We are facing a problem while adding steps in Test studio.

When we are working web and wpf at a time we are not a able to add new steps into Wpf test and while adding the code which is lies in Webtest that is deleting.

Please let me know solution for this problem.

Please find the attachment of error message which we are getting while adding steps.

Is there a property like EnableNavigation of asp.net RadCalendar for the WPF RadCalendar?
if not, how can I disable the title navigation's buttons?

thanks.

public override bool RemoveItem(FilterNode node)
{
    return base.RemoveItem(node); // This method call produces the error output below
}

System.Windows.Data Error: 40 : BindingExpression path error: 'Visibility' property not found on 'object' ''DiagramViewModel' (HashCode=33233561)'. BindingExpression:Path=Visibility; DataItem='DiagramViewModel' (HashCode=33233561); target element is 'MyChartShape' (Name=''); target property is 'Visibility' (type 'Visibility')
System.Windows.Data Error: 40 : BindingExpression path error: 'IsSelected' property not found on 'object' ''DiagramViewModel' (HashCode=33233561)'. BindingExpression:Path=IsSelected; DataItem='DiagramViewModel' (HashCode=33233561); target element is 'MyChartShape' (Name=''); target property is 'IsSelected' (type 'Boolean')

I have a shape style that does some binding:

<Style TargetType="views:MyChartShape" x:Key="MyShapeStyle">
        <Setter Property="Visibility" Value="{Binding Visibility, Mode=TwoWay}" />
        <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />


Probably not critical, but I believe these errors could indicate a performance issue. The node's shape is obviously rendered when it has been removed (along with its DataContext).

I want all my RadTabItem views to be built immediately. Currently, the visual tree is built when the tab is selected:

<telerik:RadTabControl
                       IsContentPreserved="True"
                       IsSynchronizedWithCurrentItem="True"
                       SelectedIndex="{Binding CurrentTabIndex}"
                       DropDownDisplayMode="Visible" IsTabStop="True">
  <telerik:RadTabItem Header="A" IsSelected="True">
    <views:MyView1 />
  </telerik:RadTabItem>
  <telerik:RadTabItem Header="B">
    <views:MyView2 />
  </telerik:RadTabItem>
  <telerik:RadTabItem Header="C">
    <views:MyView3 />
  </telerik:RadTabItem>
</telerik:RadTabControl>

I want all tabs, "A", "B" and "C", to be created immediately. (This is essential for one very complex problem that I'm trying to solve here.)

This is probably a basic WPF question, and not specifically Telerik related, but I figured I'd ask here. I am trying to create a reusable control, right now named SectionLayout, which allows the user of the control to define "sections", with Visuals in each section. I want to render this using RadTabControl.

Basically, the consumer of the SectionLayout would be using it like this:


I've already got most of it working. SectionLayout has a "Sections" property, of type SectionCollection, that holds items of type Section. Section has Name and Content properties. Name is a string, Content is an object.

The ControlTemplate for SectionLayout currently looks like this:


So, basically I'm just making an easier interface to use a RadTabControl. So I can reuse it in other places. Though it might change from being a RadTabControl to something else in the future.

The problem I'm having is getting the original DataContext of Section.Content property to flow into the RadTabControl.ContentTemplate. The ContentTemplate is of course given the business object (Section) as it's datacontext. So, I can easily present Section.Content. However, when I do so, Section.Content begins inheriting the DataContext given to it by the ContentPresenter, which happens to be Section.Content.

How can I do this properly? I want the user to be able to use my control as he would any normal layout control: Grid, Canvas, StackPanel, whatever. But, I need to use a TabControl internally to do the layout.

Just so you know, there are multiple errors here: http://www.telerik.com/help/wpf/radchartview-axes-datetimeaxes.html (XAML and VB).

Hi,

I'm using RadPivotGrid with Column Group:

            <pivot:LocalDataSourceProvider.ColumnGroupDescriptions>
                <pivot:PropertyGroupDescription PropertyName="Periodo" CustomName="Período" SortOrder="Descending" />
            </pivot:LocalDataSourceProvider.ColumnGroupDescriptions>
As the attachement image shows, I've put the total before column groups. It's a native control feature.

Now I want:

1 - That totals  cells have lines like group cells;
2 - Alternating backgroung color for group cells. Example: group A cells background diferent from group B cells background.

How can I achieve this?
