Hi,

We are looking for a control which we can use for searching through multiple columns in a combo box. Use case is...as user types into the combo box, the data in the combo box should be auto filtered and when user selects a row using up/down keys and press enter, current row should be selected.

I can see that Telerik has a similar control for winforms but I am wondering if we have similar control for WPF too.

In our application we uses controls from 2 different vendors, where one vendor is telerik. I will check the availability of the similar control with other vendor too. But if Terelik can provide us such a inbuild control then it will be easy for us to move to Telerik only controls in future.

Thanks,
SK

Hi,

 

We started toreplace our controls by telerik ones and noticed that the combobox wasn't getting the background of the theme we are using (Office 2016). It was keeping a gray gradient background.

 

After some investigation with the XAML forTelerik.Windows.Control.Input, the style for NonEditableComboBox consists of a grid with two borders and a RadToggleButton inside of it.

 

After some investigation, I noticed that adding the following lines to the toggle fixed my problem:

Background="{TemplateBinding Background}"
Height="{TemplateBinding Height}"

(Height had to be added for the highlight border as well)

Is this a bug? Or the expected behavior is that when using a RadComboBox the developer wont be able to get the background from the theme or be able to set the height?

Thanks!

Radgridview ist filled with data from database. CRUD works fine.

The RadGridview doesn`t show any changes made outside in the database.

Adding Mode=TwoWay cause readonly error of the QueryableEntityCollectionView data binding

We are showing a that represents a customers budget weeks which can start (WK 1) on any day in the year and are also not always 52 WKs/12 months.

It appears a provider is not the correct approach as the weeks are not bindable, hence the delay to get them from a means the data is not available when the provider is calling its format and interval requests.

Is this achievable?

Thanks,
Maurice

Hello,

I use save/load functionality of Docking. I would like to save content of each RadPane to the same file where layout stores, so I would like to get something like this:

<?xml version="1.0" encoding="utf-8"?>
<RadDocking>
    <SplitContainers>
        <RadSplitContainer Dock="DockedLeft">
            <Items>
                <RadPaneGroup SelectedIndex="0">
                    <Items>
                        <RadPane IsDockable="True" Header="Pane1" >
                            <!--My content here-->
                        </RadPane>
                    </Items>
                </RadPaneGroup>
                <RadPaneGroup RelativeWidth="100" RelativeHeight="100" IsAutoGenerated="True" >
                    <Items>
                        <RadPane IsDockable="True" Header="Pane1" >
                            <!--My content here-->
                        </RadPane>
                    </Items>
                </RadPaneGroup>
            </Items>
        </RadSplitContainer>
    </SplitContainers>
</RadDocking>

 

I found an old answers in the forum which say that it is not possible. Is there a chance that something changed?

If it is not possible maybe you could suggest a solution? I wanted to store the layout and content in one file.

Thank you in advance

The following ArgumentException is throwing from Telerik.Windows.Data.PropertyPathDescriptor.GetPropertyDescriptor(PropertyToken token, Type componentType) when a RadGridView binds:

throw new ArgumentException(string.Format(CultureInfo.CurrentCulture, "Property with name {0} cannot be found on type {1}", new object[] { token.PropertyName, componentType.GetTypeName() }));

gives: "Property with name AfterQty cannot be found on type Object"

Sample:
<telerik2:RadGridView Width="Auto" AutoGenerateColumns="False" HorizontalAlignment="Stretch" ItemsSource="{Binding SelectionList.SelectedItem.Funds}"  >
 <telerik2:RadGridView.Columns>
   <telerik2:GridViewDataColumn DataMemberBinding="{Binding Fund}" Header="Fund" IsReadOnly="True" />
   <telerik2:GridViewDataColumn DataMemberBinding="{Binding BeforeQty}" Header="Before Qty" IsReadOnly="True"/>
   <telerik2:GridViewDataColumn DataMemberBinding="{Binding CurrentQty}" Header="Order Qty" />
   <telerik2:GridViewDataColumn DataMemberBinding="{Binding AfterQty}" Header="After Qty" />
...

SelectionList is an observable collection in another gridview, the details of which load in this one.  Funds is an observable collection on the selected item of the SelectionList.

The first time this binds there is no error.  However, on subsequent selections from the SelectionList, the ArgumentException throws. 


Edit: This happens for each column.  Version 2010.2.924.35

In my application I am using the RadRichTextBox to allow users to add formatted "Notes".

Once created, these "Notes" are displayed in a Listbox, as read-only notes.

Since there can be dozens of "Notes" on a page, I am concerned that using the RadRichTextBox in the ListBox, is a bit "heavy" performance wise.

Is there a more efficient way of displaying these?

I have several curves on a single plot which are populated with a SeriesProvider like as follows:

<telerik:RadCartesianChart.SeriesProvider>
    <telerik:ChartSeriesProvider Source="{Binding DataToPlot.OperationConditions}">
         <telerik:ChartSeriesProvider.SeriesDescriptors>
            <telerik:CategoricalSeriesDescriptor ItemsSourcePath="DataPoints" ValuePath="Magnitude" CategoryPath="TimeLabel">
                <telerik:CategoricalSeriesDescriptor.Style>
                    <Style TargetType="telerik:LineSeries" BasedOn="{StaticResource LineSeriesStyle}">
                                                <Setter Property="LegendSettings">
                                                    <Setter.Value>
                                                        <telerik:SeriesLegendSettings Title="{Binding Name}"/>
                                                    </Setter.Value>
                        </Setter>
                    </Style>
                </telerik:CategoricalSeriesDescriptor.Style>
            </telerik:CategoricalSeriesDescriptor>
        </telerik:ChartSeriesProvider.SeriesDescriptors>
    </telerik:ChartSeriesProvider>
</telerik:RadCartesianChart.SeriesProvider>

 

In addition, I have another set of data which I should populate on the same plot with the same X-axis values (date/time). However these data have another order of magnitude (another physical meaning), so the only way is to add additional Y-axis on the same plot. I have the following xaml-code:

<telerik:LineSeries ItemsSource="{Binding Path=DataToPlot.VibrationConditions}"
                                            CategoryBinding="TimeLabel"
                                            ValueBinding="Magnitude">
                            <telerik:LineSeries.VerticalAxis>
                                <telerik:LinearAxis HorizontalLocation="Left" ElementBrush="Green"/>
                            </telerik:LineSeries.VerticalAxis>
 </telerik:LineSeries>

 

When these blocks of code are located one after other, the former (data which are populated with a SeriesProvider) is depicted on a plot as I expected, but the latter (data which are populated with LineSeries) is depicted as a vertical green line to the left of the first Y-Axis (see attachment).

Is is possible to combine multiply Y-data (from various sources and distinct populating mechanism) on a single plot?
