Hi Everyone,

We are testing RadTreeView application  with CUIT. Whenever we test header less RadTreeView has single column with Microsoft Coded UI.is giving same name property value for all rows, but in wpf , CUIT name property value is row content.

Can you help me here to get unique names(row content) for rows.
for more details please see the attached image.

Hi Folks ,

I have  telerik:RadGridView Data binded to QueryableCollectionView and I clear the descriptors using the following line 



it works fine but still the searched text appeared in FilterRow cell . How can I clear the filtered row too ?

Hi Everyone,

I want automate RadTreeListView control using Coded UI. How can I provide unique Automation Id's to Rows and Cell to identify controls uniquely

Source:
===================
  <Grid x:Name="LayoutRoot" >
        <telerik:RadTreeListView x:Name="radTreeListView"
                            AutoGenerateColumns="False" ShowColumnHeaders="False">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" />
            </telerik:RadTreeListView.ChildTableDefinitions>
            <telerik:RadTreeListView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" AutomationProperties.Name="{Binding Name}"  AutomationProperties.AutomationId="{Binding Name}"/>               
            </telerik:RadTreeListView.Columns>
        </telerik:RadTreeListView>
    </Grid>
===============================

But in code I am binding AutomationProperties.Name to some value but whenever I test control with CUIT AutomationId not coming which I have binded value

Hello,

I've been trying to solve the riddle of setting my chart's LegendLabel items. What I have is a query that provides a result set from a database. Two of the items are mapped (see code below) and I'm trying to figure out how to get the LegendLabel to display the appropriate info.

Here is my code segment:

            radChart.DefaultView.ChartLegend.Header = "Series";
                
            radChart.DefaultView.ChartArea.DataSeries.Clear();
            radChart.SeriesMappings.Clear();
            radChart.ItemsSource = this.getChartData();
            radChart.DefaultView.ChartTitle.Content = _chartTitle;
            //radChart.DefaultSeriesDefinition.LegendDisplayMode = LegendDisplayMode.DataPointLabel;
            //radChart.DefaultView.ChartLegend.Items.Add(new ItemMapping("Series"));
            radChart.DefaultView.ChartLegend.UseAutoGeneratedItems = false;

            SeriesMapping seriesMapping = new SeriesMapping();
            //seriesMapping.LegendLabel = "Series";
            seriesMapping.SeriesDefinition = new BarSeriesDefinition();
            //seriesMapping.ItemMappings.Add(new ItemMapping("Series", DataPointMember.LegendLabel));
            seriesMapping.ItemMappings.Add(new ItemMapping("Scenario_name", DataPointMember.XCategory));
            seriesMapping.ItemMappings.Add(new ItemMapping("Overall_RC0_Pct", DataPointMember.YValue)); 
            radChart.SeriesMappings.Add(seriesMapping);


I scoured numerous simliar posts to my query but haven't been successful yet. I was a bit confused as to what property I needed but as you can see I've set my Legend Header to the word "Series"

I want the items below to display the actual content of the underlying result set that comes from a column named "Series". So what the only time I see anything generated is when I set the "UseAutoGeneratedItems" to true and all I see is 'Series 0'

I tried mapping to the LegendLabel but I am not sure if that is correct or if I need to map to the ChartLegend.Items? If that is how I need to go what is the actual syntax to do that. 

Thanks again for your help!

It is really easy to implement MergeField functionality. However sometimes I don't want the user to see the property-names of my MailMerge-Class but use different names, especially since properties don't allow spaces. Is it possible to use something like the "Display" annotation to have "speaking field names" instead of class properties? E. g. something like this:


and RichTextBox takes the "Display" annotation to display the MergeField?

Hello.

My scenario is pretty streight forward:
1) User docks a Pane to arbitrary position by dragging it with a mouse.
2) He then undocks it.
3) He then clicks a button which is supposed to dock the pane back where it was before undocking.

How do i impement (3) ? Is there an example somehere? How do I "store" position of single docked Pane in docking tree, and how do i "restore" it when needed?

Hi,

Wondering if there's a way to specify custom Measurement Unit for my Diagram, for the sake of the labels. I want the labels to show intervals in (x) units, instead of the current MeasurementUnit. Or what is a good way to customize the LabelContainer style?

Thanks!

I would like to enable users to copy a chart to the clipboard, preserving appearance and transparency, so I've chosen to use PNG as the format.

However, when I paste from the clipboard, all of the transparent areas are black, which is not desirable. I don't have much experience with clip board operations, so perhaps I am doing something wrong, though other than the transparency is seem so work fine. Is there a way I can accomplish this either and either preserve the chart's transparency or at least grabbing a rendering of the chart using its current background (almost always white)?

Hey,
I've been trying to create a tooltip for a PieDataPoint, but had a couple of difficulties.
Basically, I would like to use the standard tooltip, but I could only find examples showing overriding the tooltip template for this cause. So I tried to create a similar template myself - which caused some bugs.
Mainly, I couldn't get the tooltip size to change according the content (like the strings lengths in the texblocks, I guess it'll be clearer in the xaml).
Another bug (I Believe it's another symptom of the same bug) - inside the tooltip I used a GridRows with Auto height. It seems like it calculates the row's height correctly only the second time it shows the tooltip.

This is the xaml:

Is there any way to use WPF default tooltip? If not, What am I doing wrong?

I have a RadGridView that is working nicely, but  I have trouble with the expression Column:

1) I let the expression Column show via right mouse click. It is empty.
2) I click the Header of the Explession Column
3) RadGridView obviously tries to sort the empty Expression Column and  crashes with the CallStack posted below.

I want GridView to be stable, so whatever the user does it should not crash only because the Expression column is empty

How do I achieve this?
