Hello everybody, 
The customer asked me an application with tabs and docking.
The application is composed by 4 tabs and inside those tabs there are more tabs and in those there are the dockings.
Tab1
Tab2
--TabSub1
----Docking1
--TabSub2
----Docking2
--TabSub2
----Docking3
Tab3
Tab4

When I click on the tab2 I can see everything ok.
If i click on the tab2 and then TabSub3, TabSub1, TabSub2 and afterwards I go to Tab1 and then again in the Tab2 I can see that automatically the TabSubs start to change alone, like if they need to update the docking and then will stop in the last that i select (TabSub2).
There's a solution? I mean, I can say to the Docking to don't request to get "refreshed"? or to don't show that the tabs are moving, like something that you wait until the changes are done and then you show the Tab (In this case the Tab2).

This is the video to show the problem:

Hello Telerik Team,

I am implementing the WPF Chart in a scenario with lot's of data, so sampling is critical to keep drawing performance high.

What I need is basically a custom "keepextremes"-function when sampling data.
Currently, keepextremes keeps smaller values of the value is smaller than zero, and larger values of the value is larger than zero. Is this correct? If so, I need to change the value where the graph sampling decides wether to keep the lower value or the higher value to - for example - keep max values if the value is greater than 4, and keep min values of the value is below 4.

Is this possible?

best regards

Ulrik

Hi to all, I set the ShowInsertRow to true, but at runtime the new row isn't show.
I try to set the same ItemSource in a standard WPF toolkit datagrid and the new row works fine.
Am I missing something ?

I've if it does, I can't seem to find it on in your documentation.

Drag and Drop

When I using flow direction right to left on the Grid  view the drag and drop act strange

Someone know this problem?

Hi,
I'm new with Telerik controls and am testing the demo Telerik WPF controls.
I have a problem with Right To Left support:

I create a new "Rad Control Browser Application" project. Then in "Page1" page, set it's FlowDirection property to "RightToLeft", then I place a button in this page, and in it's click event instantiate a RadWindow inherited control.
In this window I try to place some drag and drop samples. For example I place two tree with IsDragDropEnabled sets to true (It's not matter, I also test samples provided with WPF controls).
The problem is here:
When the FlowDirection property of the page is "LeftToRight" all things works well, but when this property is set to "RightToLeft", If I drag somthing for example from right to left it will move in opposite direction from left to right.

Note that I change the page's FlowDirection property, not the window. when I just change the window FlowDirection property all things are well. The problem is from page's FlowDirection property.

Sorry for my bad English. :)

Here is my source codes, please see these if my explanation is confusing.
I will attach an image of the result.

So, Any Ideas?

Thanks.

In our application we need all the space we can get.
That's why we want to minimize the width and/or height of all our scrollbars.
In an resource-file we wrote this:

Is there a way to set a panning range for left, right, bottom and top.  I want to restrict a user to only pan to the edge of the map and not off the map.  Also, is there a way to restrict on how far a user can zoom down or up.  I instantiated the event handlers for zooming and panning  but wondering if there is an easier way to set a range.

void

 

 

RadMap1PanningFinished(object sender, RoutedEventArgs e)

 

{
    // TODO: Check if center is within panning range?

 

}

 

 

void RadMap1ZoomChanged(object sender, EventArgs e)

 

{

 

 

    if (this.RadMap1.ZoomLevel > 6)

 

 

 

        this.RadMap1.ZoomLevel = 6;

 

 

 

    if (this.RadMap1.ZoomLevel < 3)

 

 

 

        this.RadMap1.ZoomLevel = 3;

 

}

Please let me know. Thanks

Hi,

I'm using RadSlider in range mode and doing TwoWay databinding on SelectionStart and StelectionEnd properties. I set the values within Minimum/Maximum range. However, the very first time during dialog load the Slider coerces SelectionStart value to 0. 

This is the slider code:

Initial valud of SelectionStart is set to 3.0. In the attached screenshot you can see how the value is being set to 0 from CoerceSelectionStart method.

Please let me know if I'm doing something wrong or there is a way to fix it.

Thank you,
Ruben

Hello,

I have a Carousel populated with Observsable collection using MVVM. I want to be able to filter the carousel with a button click event.

Any Samples would be great
