     I am programatically moving the scroll bar on my chart as data comes in but I want it to stop if a user takes control of the scroll bar on the horizontal axis.

Is there a simple way to do this?

Right now I am keying off of the rangechanged event to see if my minimum is less than the previous minimum but this only works for scrolling backwords and I cannot do this for forwards since the event is fired when I need to shift it programatically also.

Hello,

With this provider, the mini map is no more displayed.

That's certainly because you have introduced the StandardModeUserAgent property and this property is not copied to the mini map...

I want to use Telerik implicit styles because this seems to be the favorite technique to use with Telerik controls. 

So I use the Telerik noxaml dll's in my project.

I have made a separate class library in which I have included the Telerik resources (the theme resource files). These resources are merged at startup (in the Application class) using code like

 

Current.Resources.MergedDictionaries.Clear();
Application.Current.Resources.MergedDictionaries.Add(new ResourceDictionary
{
    Source = new Uri("/libraryDll;component/Themes/System.Windows.xaml", UriKind.Relative)
});

 

When running the application all works fine and the radwindow is displayed and styled correctly.

However, at design time I don't see anything. This is (of course) because at design time the xaml resources are not available (loaded).

 

How do I fix this problem so I can see the telerik controls at design time? If you can't see the controls you can't design a window can you?

 

Regards,
Peter

After changing the axis maximum here I want to have the step size change so I can see a label for 130.  How can I accomplish this? 

 

<telerik:RadCartesianChart    ClipToBounds="False"  Margin="20">
    <telerik:RadCartesianChart.HorizontalAxis  >
        <telerik:LinearAxis  Maximum="130" LastLabelVisibility="Visible" >
        </telerik:LinearAxis>
    </telerik:RadCartesianChart.HorizontalAxis>
    <telerik:RadCartesianChart.VerticalAxis >
        <telerik:LinearAxis />
    </telerik:RadCartesianChart.VerticalAxis>
    <telerik:RadCartesianChart.Series>
        <telerik:ScatterAreaSeries >
            <telerik:ScatterAreaSeries.DataPoints>
                <telerik:ScatterDataPoint XValue="30" YValue="1"/>
                <telerik:ScatterDataPoint XValue="130" YValue="1"/>
            </telerik:ScatterAreaSeries.DataPoints>
        </telerik:ScatterAreaSeries>
    </telerik:RadCartesianChart.Series>
</telerik:RadCartesianChart>

I have placed a text box control and I have to write validation rule for it.

But the problem is I have bound a collection to the grid view and I have declared only two columns 

one for binding Name

other for value [data template changes depending on property] so I have  overridden selecttemplate method . Based on the item input I have choosen the datatemplate.

Now if write a validation rule for text box ,it applies for all the text boxes in grid.The rule should be individual for each textbox

Can you help me resolving the issue.

Can we get an example of ColumnSyncBehavior?  It would be really great if we could sync columns between gridviews.  I was going to write something like this, but if it's already supported by telerik I'd prefer to use that.

Dear support,

When I click "Add", fill-in data and then "OK", the data has successfully put in the collection but "Add" button is still disabled.
I have to click "Edit" follow by "Cancel" so that the "Add" button become enabled again.
What's wrong?

Hello,

I'm trying to connect a connector with the shape created dynamically when a connector is created from a existing shape but the user drop the connection on an empty space.

 

Actually i m able to create the new shape at the right position (on the EndPoint of the connection) but i m possible in the AddLink method to associated the connection with the new shape on the right connector .

 

The connection is never associated with the connector when i set the TargetConnectorSource

As stated in http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/getting-started/getting-started I added the below references to my WPF project and a simple XAML declaration of RadRichTextBox and the project builds fine and RadRichTextBox is visible in Visual Tree while debugging but it is not rendered on the screen using both VS 2015 and VS 2017. If I replace it with standard WPF RichTexBox everything works fine. I am unable to find anything on this problem in forums or in documentation so what is the problem here and how to resolve it?

Sample project attached (It's a zip file but it's not allowed so I changed the extension to jpg).

     I am programatically setting the RangeEnd and RangeStart of the scroll bar and moving it dynamically as data comes in. This works fine until you manually move the scroll bar. There is a case where the data is reset and I set RangeStart back to 0 and RangeEnd to a number greater that that (0.25 for example) but the scroll bar stays where it was if the user has touched it. If the user has not touched it the scroll bar resets just fine. I am curious if in the logic there is a setting that prevents setting RangeEnd and RangeStart once the scroll bar has been scrolled manually? If so is there a way to reset it outside of recycling the object?
