I am using Telerik RadGrid control in my ASP.NET web application. Grid columns are generated automatically from the data source. Also Grouping, sorting, Filtering, Aggregates etc are enabled for the columns in the grid. When I save the Grid setting I can see in the saved xml content that it also persists Aggregate function which was applied to the columns. The value of  XML node "PersistableColumnSetting>Aggregate" is "SUM"

but when I revisit the page next time, I notice the Aggregate functions are not applied to the column after loading the settings and rebinding the grid.

I wonder if this is by design or there is another way to apply the Aggregates to the columns just like they were when saving the settings

Thanks

Hello,

I have a RadComboBox that looks like this:

<telerik:RadComboBox Command="{Binding ResourceDropDownClosedCommand}"
                     ItemsSource="{Binding ResourceLookupData}"
                     AutoCompleteSelectionMode="FullMatch"
                     telerik:TextSearch.TextPath="Id"
                     AllowMultipleSelection="True"
                     UpdateTextOnLostFocus="False"
                     IsEditable="True"
                     TextSearchMode="Contains"
                     IsFilteringEnabled="True"
                     telerik:StyleManager.Theme="Windows7"
                     Grid.Column="3" Grid.Row="1">

    <telerik:RadComboBox.ItemTemplate>
                            
        <DataTemplate>
            <Grid Width="500">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="85"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>

                <TextBlock Grid.Column="0" Text="{Binding Path=Id}" />
                <TextBlock Grid.Column="1" Text="{Binding Path=ResourceDescription}"/>
            </Grid>
        </DataTemplate>
                            
    </telerik:RadComboBox.ItemTemplate>

    <telerik:RadComboBox.FilteringBehavior>
        <controlsHelpers:RadComboBoxResourceLookupFilteringBehavior />
    </telerik:RadComboBox.FilteringBehavior>

    <i:Interaction.Behaviors>
        <controlsHelpers:RadComboBoxSelectedItemsBehavior SelectedItems="{Binding SelectedResources}" />
    </i:Interaction.Behaviors>
                        
</telerik:RadComboBox>

The problem i am facing is that after the user has entered text and the RadComboBox has filtered the Items depending on the entered text, after losing focus of the RadComboBox by tabbing or clicking away, If there is no item that matches the entered text then the text is cleared, even with the UpdateTextOnLostFocus set to False.

I haven't been able to find a solution that works for me. So any suggestions would be appreciated.

Thank you

Hello,

i have a problem with the radRichTextBox, when using .docx files generated with the Telerik Report Designer. (Screenshots attached)

If I create the document by myself in word, the header will be displayed correctly in the radRichTextBox (with RadRibbon).

The telerik control seems to have problems with the table structure inside of the header, as well as hyperlinks that were generated with telerik report Designer.

Does anyone know a solution?

I think that this is a general question: I have a RadDocking with document host. Generally I can load many tab inside the panel, every tab has his viewmodel that it is an instance of the same class.
When I binding a control property to a viewmodel property I need to bind it to the correct instance.
Now I use binding in code behind using a variable index such as 

pane.SetBinding(RadPane.HeaderProperty, new Binding()
{
    Path = new($"MainVM.Partitions[{_vm.MainVM.PartitionAttiva.Partition.Id}])
});

Hello.  I'm trying to create a vertical RadSlider with a custom Thumb that will display the current value of the slider, and has a pair of up/down buttons that the user can click to increment the slider by a fixed amount.

I've styled my Thumb to have Height="30" and Width="100", and the custom thumb appears as expected.  However, there are two problems.  First, because my RadSlider has Orientation="Vertical", I'm only able to drag the slider until the thumb is 100 px below the top of the slider - the width of the Thumb.  When the Thumb is at the maximum position, the slider value is 100% - but I'd like the Thumb to move through the entire length of the slider's Track.

The second problem is, when the slider is set to zero, the custom content of my Thumb appears below the bottom of the slider - I would like it to be centered on the bottom of the slider's Track.

Setting a margin on the Thumb only changes the proportion of "dead" space in the slider; if the Margin is 50, then I can only drag to within 50 px of the top or bottom of the slider.

Thank you!

When I use the WindowsFormsHost in Radbusyindicator,

then I change the window size, and the UI shows very slowly and seems wrong.

The content of the WindowsFormsHost is just a Label.

I am not sure if there are some details in this case.

<telerik:RadBusyIndicator IsBusy="False">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
                <RowDefinition Height="30"/>
            </Grid.RowDefinitions>
            <WindowsFormsHost>
                <cc:UserControl1/>
            </WindowsFormsHost>
        </Grid>
    </telerik:RadBusyIndicator>

Hello! I have a RadGanttView with custom columns (which can be switched on and off on fly). The problem is that after any interaction with this control GridView part shows horizontal scroll bar, but splitter doesn't go right although there is more than enough space to resize (Picture 1).

It doesn't really matter how many columns are there - GridView resizes itself to be a bit smaller than enough to fit all the columns and doesn't expand anymore (Picture 2), leaving at least 0.5 cm of free space on the right (on 17" FullHD display) (Picture 3).

At the same time there is no problem with shrinking, it's possible to move splitter to the left until GridVIew part becomes completely invisible.

Thanks, Dmitrii

UPD: I've checked variables in Dynamic Visual Tree and found that ExtentWidth of TreeRenderingPanel element is always 3 units more than needed. Is there a way to fix this?
