I'm trying to show a tooltip in the needle in order to show the selected value.

I have this code in the xaml file:


And I wanted to add the tooltip format in the code behind file:


But when I run the program, it only shows a blank square, as you can see in the image that I have attached.
I think that I am missing something.

I saw this Page and i tried this code:


But it doesn't work either.

Hello,

I want to make a radgridview which columns and rows depends of the selected items in two combo boxes. Right now I'm doing that by creating a data table each time the selection changes and assigning it to the radgridview itemsource... It's woks fine with few elements but if one of the selection (for example, cities) has a lot of columns the grid stops working.... Is there a better way to implement this?

I've attached you an image of what I have for better understanding
Thanks!

Hello,

2.All labels have the equal width (= max {with = auto})
 

Hello everyone,

I'm posting in General Discussions because I'm not sure which control to use.

I want to display properties of two objects side by side for comparison.  Is it possible to add more columns to PropertyGrid? That would be perfect for me.

I cannot use GridView because it displays records in rows (I want them in column like in PropertyGrid). Is there a way to swap rows with columns in GridView or specify orientation? Just like in StackPanel?

I'm open to any other suggestions as well. 

Thanks,
Umar

Hi Telerik team,

 I want to filter columns by specifying wildcards. Is there any way to specify the wildcard as bellow:
 columnFilter.FieldFilter.Filter1.Value=cell.value;

I have another query regarding the performance in gridview. I had binded the grid to a datatable with 100 columns X 10000 rows. When i apply programmatic filtering or sorting, the grid lags. I had enabled the virtualization in the grid, but it didnt had any improvement. 

Is there any other way to filter the columns in the grid other than specified in your help . i had used IColumnFilterDescriptor , but its slow. Is there any other way to filter .

Following are the system environment:
WPF version: 4.5
OS: windows 7
exact version of the Telerik product: 2013 Q2 SP1
preferred programming language :  C#

Hello,

We work on a project with EF5 (DbContext) and MVVM WPF Light Toolkit.
So, to load data on the RadGridView, we try to use QueryableEntityCollectionView, instead of RadEntityFrameworkDataSource, it seems to be the good approach ?

But when we want to include graph object when we load entities (with relatedObjectsToInclude in the ctor) when have a problem with the inheritance of the model because we have 2 levels. The message is : 

An include path specified is not valid. The EntityType 'OPY.Entities.Sinistre' does not declare a navigation property with the name 'Agent'.

The model :


The code :


As you can see, we want to load "SinitrePS" with all derived but we are forced to use "Sinistres" (top level) as entitySetName because the SinistrePS class don't have it own entityset on the model. 

How can we do ?
Thx

Hi

I am facing tab index ordering issue. See the screenshot. When tab key pressed, i want to navigate like 1,2,3.......18,19,20. I have also included a sample project code here:

Hello,

I attach the sources to reproduce the issue. I used Q3 2011. I've a grid bound to a list of items that have a property "Name". This name can be wrapped inside the datatemplate of the gridview column. If you scroll down to the bottom of the grid, the last item is not fully visible (please see attached screenshot for details). In some cases the last item is not visible at all, depending on the size of the wrapped text and the width of the column. I've played with different sizes and was able to reproduce the issue.

We have an application in production and this issue is very important for us.

Notes: In the example, to generate test data I've used "nbuilder" that can be obtained from NuGet.





Feedback is appreciated.

Thanks.

Hello,

I'm extending your RadCartesianChart to provide Legend support. Creating them manually is not an option for us (all series are dynamic and mapped to signals configured by user), and we don't want to create user control which will contain RadCartesianChart and Legends because we need to access all properties of RadCartesianChart directly on our control because they will be configurable in external tool.

The problem I've encountered is that RadCartesianChart ignores this template and just takes the width and height of the whole control,
and not the size which was given in this template. In the end I always get legend over the graph area as if I were using Grid for layouting.

How can I resolve this?

Control template I've created for my control is this:

  <ControlTemplate TargetType="{x:Type CartesianChart:ConfigurableCartesianChart}">
                        <DockPanel LastChildFill="True">
                            <Grid Width="{TemplateBinding LegendWidth}"
                                  Height="{TemplateBinding LegendHeight}"
                                  DockPanel.Dock="{TemplateBinding LegendPosition}"
                                  Margin="5">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="Auto" />
                                    <RowDefinition />
                                </Grid.RowDefinitions>
                                <TextBlock Margin="2" VerticalAlignment="Center" Text="{TemplateBinding LegendTitle}" />
                                <ItemsControl ItemsSource="{Binding Series}" Grid.Row="1">
                                    <ItemsControl.ItemTemplate>
