Hello, I'm trying to do a project where I have a few checkboxes that correspond to different series. When the checkbox is checked, the series is displayed, and if the checbox is unchecked, the series is collpased. There are two problems with this:

1) The legend still shows the collapsed series
2) The values on the Y axis are not recalculated as the series go away. For example: If series "A" has max value is 5000, and series "B" max value is 250, when hiding "A" the Y values keep showing all the way up to 5000.

How can I fix these two problems?

Thank you,

- Carlo

TabControl Intellisense Issue

I am leveraging the WPF Telerik libraries for a simple Tab control. Weird enough the exact same code/solution works on my personal computer but gives the following error on my office machine:

Code

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    Title="MainWindow" Height="350" Width="900">
<Grid>
    <telerik:RadTabControl>
        <telerik:RadTabItem Header="Dashboard Summary" Width="200" Background="Gray">
        </telerik:RadTabItem>
        <telerik:RadTabItem Header="Details" Width="200" Background="Gray"  />
        <telerik:RadTabItem Header="Policy Tester" Width="200" Background="Gray"  />
    </telerik:RadTabControl>
</Grid>
</Window>

The exact same 3 libraries are being referenced but the same code on my office machine renders the tabs but doesnt give me intellisense and keeps throwing the following error:

Execute a command when the Enter key is pressed

<telerik:RadMaskedNumericInput Value="{Binding Quantity, Mode=TwoWay}">

<telerik:RadMaskedNumericInput.InputBindings>

<KeyBinding Key="Enter" Command="{Binding DoSomethingCommand}" />

<KeyBinding Key="Tab" Command="{Binding DoSomethingCommand}" />

</telerik:RadMaskedNumericInput.InputBindings>

</telerik:RadMaskedNumericInput>

I am trying to call to a command when the Enter key is pressed like an exemple above.
The Tab KeyBinding works perfectly, but the Enter doesn't work.

This behavior works in a TextBox, is this possible in a MaskedInput?

[Solved] Instant Item Height

Dear support,

I have the problem, that I want to set the instantitem height to the actualheight of the timeline.
The problem is that if the instantitem height extends the height of the 'normal' items, my timeline extends it's height -> can see it on the vertical scrollbar.
Is there a way to set the instant item height to the actual height of the timeline?
The reason is that we want to see the instant items even when the user scrolls down.
I have attached an image with the desired behavior.

You can test the the bevavior with that small piece of code:

RadGridView RowStyleSelector Condition With a Dataset ItemSource

Hi,
I want to use a RowStyleSelector in a RadGridView to make rows Expandable or not depends on the value of a column of my ItemSource.
ItemSource is a Dataset that contains a DataTable (ID, Name, Type, SerialNumber, ...).
I need to make rows expandable if the Type ='Updated'.

My actual code (below) is not working:

<telerik:RadGridView.RowStyleSelector>
<telerik:ConditionalStyleSelector>
<telerik:StyleRule Condition="Type = Updated">
<Style TargetType="rad:GridViewRow">
<Setter Property="IsExpandable" Value="False" />
</Style>
</telerik:StyleRule>
</telerik:ConditionalStyleSelector>
</telerik:RadGridView.RowStyleSelector>

Source code for thumbnail demo?

I'm evaluating the PDF Viewer and it works great! However, when I try to use the code for the thumbnail demo as a starting point in my application I'm getting an exception. The code I'm using is that which you can copy and paste from the Telerik WPF Controls Examples application, where you can switch between Example and Code.

Is it possible to get the actual .csproj project for the PDF thumbnail viewer sample?

Thank you.

Text Tool

Hi,

I'm interested to implement some sort of annotation tool using the WPF RadImageEditor as a basis. I'm glad there is already a Text Tool in the demo version. But there are a few things lacking which I would like to implement.

1) Currently seems that once a text object is created, it cannot be reselected and moved/edited. Is it possible to implement such that a previously created text object can still be selected upon clicking on it?

2) Are there any existing tool for drawing lines/arrows/borders? If not, do you have some sample code to create such tools? Would be good to have such features in an annotating software.

3) Does the ImageEditor have a panning feature? I.e. mouse click and hold and drag to pan the image? Any idea how to implement this?

Thanks for your help.

issue with pdf exported by RadDocument

Hi,
We noticed that the export to pdf function do not realy generate a good pdf files.

In fact we use the export function to generate pdf files, then these pdf files should be indexed to simplify our search function.

But when we try to index the pdf file generated by the RadDocument, we have an exception because the the pdf files is corrupted

and we try to open the file by Adobe Reader, it opened as modified file.

Do you know how to prevent this issue?

assembly version mismatch

Hi,

I installed a demo version from a website just to see what controls there are that I can use and it installs a clickonce app with version 2013.2.805.40
I install an actual msi from file server which has a separate set of dlls with different version 2013.2.0724.45 (which is supposed to be used for development, not demo)
Aparently there isn’t a proper 805 version of msi downloadable from the website
When I try to compile my project that uses MSI version I constantly get this
1. "Could not load file or assembly. Telerik.Windows.Controls, Versrion=2013.2.805.40, Culture=...."
2. Which is saying that dll I have referenced needs version 805 instead of the one I have 724 even though I never installed 805 other than demo app
3. There are no references to 805 anywhere in my project, why it wants to link to those dlls is beyond me...
When I try to remove demo app (which is supposed to remove any trace of that 805 version), I get the same error
When I try a different version msi installed after I blew 805 version (I think I tried 905) I get the same error. One would think that getting a fresh set of dlls without any remnants to 805 left in the system would fix, but no….

Your help is very much appreciated... I'm at a halt stop where I can't use any Telerik controls, and I don't know how to clean it up...
