Hi, I am new using Telerik controls and WPF, I saw the executive dashboard demo and I would like to create a chart like the one showing sales by product. I am reviewing the code but I don´t really understad it, I think the control that is used is a BulletGraph.

There is this Page where you can see how to create a BulletGraph, but I don't know how to show the lines for the actual value and the target value.

Does anyone have an example to achieve a chart like that one?

Thanks,

Alberto

When I add below  code in RadMenuItem and Trigger the print action , Mygrid is not binded and  TargetObject is null in invoke method.
It works fine for other system windows controls . Please help me to fix this issue.


 <telerik:RadMenuItem Header="Print">
i:EventTrigger EventName="Click">
                        <actions:PrintAction DocumentName="DocName" TargetName="MyGrid"  
                               TargetObject="{ Binding ElementName=MyGrid }"
                                   />
                </i:EventTrigger>

My XAML:

Hi,
I am using the diagram control in my xaml file and i have two shapes(any) . there is one textbox  to set the raddiagramshape fontsize property.

so in xaml i have implemented this like as follows

Text="{Binding Path=SelectedItem.FontSize,ElementName=frontdiagram,Mode=TwoWay}"

when i select any shape in diagram then textbox show the current fontsize of that shape and when i change the value from the textbox then it is changing the fontsize of the current selected shape .

the problem is if I selected more than one shapes then it won't work meaning it is changing the font of only one shape. so to achieve this i have took the selectionchanged even of the diagram control on shape selection change i am getting the collection of selected items and then i am able to do the font change for every selected item but undo is not working in this case. when i press ctrl + z then it won't undo the last action for fontchange . how to achieve this and why this is happening .
if i am using xaml code to achieve then multiple selected font couldn't reflect but undo work and if i use the codebehind to solve the problem then undo couldn't work
Note : - setting pane do provide this feature meaning if you select the two shapes and change the font then it will change for both shapes and undo also work in that . This same thing i want to implement for this textbox.
please help.

Hi,

I have a myRadGridView binded to a QueryableEntityCollectionView<tableName> property. All worked perfect.
But when I create a Task to fill that property (that was binded to my RadGridView) it appears a messaje saying:

Ocurrió System.InvalidOperationException
  HResult=-2146233079
  Message=El subproceso que realiza la llamada no puede obtener acceso a este objeto porque el propietario es otro subproceso.

  InnerException: 
The code I have written in the ViewModel is:

The RadGridView is:

In the ViewModel, if I change the definition of the property and the code of the Task for the next one code, it works:



So, my question is:
How can I use QueryableEntityCollectionView<tableName> in a Task?

Thanks.

I wanted to add a column chooser functionality in the gridview. I have done it in past but had a question that can it be acheived by just adding a header cell from codebehind or by any other way. I have done it by using the row indicator column and using the space on the header to open choose column window, which i have attached a image of that. 

Question here is that is there a way to hide the row indicator column and just use the extra header on top/ or code behind way to add a header cell which handles this functionality. 


Thanks,

Hello,

I have found that even though i set the correct (german) culture on currentthread and CurrentUIThread, RadGanttView still uses a 12 hour format fo display times when zoomed in. I'd like to change this to a corresponding 24-hour format, that is used the default for this culture.

I would expect the ganttview to respect certain culture settings like this.

How can i achieve this?

Thanks

What would be involved to use the diagram control in a lightswitch application (if at all possible)?

N.B. Framework 4.5

// first in Application  App.cs set at runtime theme windows8
protected override void OnStartup(StartupEventArgs e)
{           
    StyleManager.ApplicationTheme = new Windows8Theme();                   
}

// Then create two VIEW

// First is MASTER_VIEW
// ADD XAML
  <telerik:RadTabControl Grid.Row="0" >

            <telerik:RadTabItem DropDownContent="Trend Import" Header="DETAIL" >
                <telerik:RadTabItem.Content>
                    <views:DETAIL_VIEW/>
                </telerik:RadTabItem.Content>
            </telerik:RadTabItem>

</telerik:RadTabControl>

// ADD SECOND XAML -> DETAIL_VIEW
<Grid>

   <GroupBox Header="tyy tyy" >
           <TextBlock Text="Settings"/> 
    </GroupBox>
 </Grid>
      
Build and run WPF APPLICATION

TextBlock is not visible. Cannot see content(Text) of any TextBlock controls?
I use default style at all.

Workaround:
Remove: OnStartup(StartupEventArgs e) function, stay at default theme.
You will see all textblock controls again.

Additional info: This bug depends and others controls like GroupBox and others.

Framework 4.5
VS2012

Telerik v. 2013.2.611.45 (For framework 4.5)

This is styles that I use. In comment is second workaround.
