I have a Radgridview with merged cells. When I select a merged cell, the selected row in the ViewModel does not change. I need to get all rows whose cells are included in the selected merged cell. Can it be done?

We use RadCombobox (WPF) for loading more than 20000 items.

We enabled the following properties and removed the Virtualization properties. We are facing performance problems on searching the items from RadCombobox element. How can we improve performance for the RadCombobox load and search, if virtualization properties cannot be used.

<telerik:RadComboBox
x:Name="itemBox"
HorizontalAlignment="Stretch"
CanAutocompleteSelectItems="True"
DisplayMemberPath="Name"
EmptyText="Select the item"
IsEditable="True"
IsFilteringEnabled="True"
IsTextSearchEnabled="True"
ItemsSource="{Binding ItemCollection, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
OpenDropDownOnFocus="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
SelectedItem="{Binding SelectedItem, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
TextSearch.Text="Name"
TextSearchMode="Contains" />

Hello! I need to merge cells in all columns. In my example, the screenshot shows that Sam in the "Name" column is merged for two different people who are part of different companies. Is it possible to make the cells merge based on the columns on the left? That is, if Sam is part of different companies, then he does not need to be merged.
What I want is in the attachment

Hello,

 

I have a RadMaskedTextInput that I'm using for a phone number.

 

If I clear the form, and set the txtDriverNumber (that's the name of the field) using txtDriverNumber.Text = "" (and I also tried string.Empty) it looks like it clears the value correctly.


However, when the textbox gets focus again, it puts back in the last entered data.  I don't want it to do that, is there something I can do to make sure it doesn't remember previous values?

I've got a WebBrowser control nested inside a RadPane ... I've pointed it at http://loremipsumtext.com/ for some dummy content.  The content shows fine when pinned...but the RadPane is blank when simply floating.

Any suggestions?

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

Harshad

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

Marko

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?
