Filtering RadGridView in Dynamic Columns

Hello,

we have a RadGridView which we define in a .xaml file. To this grid we add a few dynamic columns via a Behavior. Our Problem now is, that the columns we defined in the .xaml-file can be filtered normaly, but the dynamicaly added columns are missing the filter icon in the column header. We tried adding a new Instance of the FilterControl which shows the filter icon, but the FilterControl does not do anything and is missing the Search Textboxes.

Can you guide us advice on what we need to do to get the filter working for those columns?

Here is the code of the Behavior we use to add the dynamic columns:

public class RadGridViewAddCustomFieldDefinitionColumnsBehavior : RadGridViewAddFieldDefinitionColumnsBehavior<CustomFieldDefinition>
{
    protected override void AddFieldsColumns(
        IEnumerable<CustomFieldDefinition> fieldDefinitions,
        GridViewDataControl radGridView,
        RadGridViewAddFieldDefinitionColumnsBehavior<CustomFieldDefinition> radGridViewAddFieldColumnsBehavior)
    {
        var corporationIDToNameConverter = new CorporationIDToNameConverter();
        var contactIDToNameConverter = new ContactIDToNameConverter();

        foreach (var customFieldDefinition in fieldDefinitions)
        {
            var column = new GridViewDataColumn
                         {
                             Header = customFieldDefinition.PropertyName,
                             UniqueName = customFieldDefinition.PropertyName,
                             DataMemberBinding = new Binding("CustomFields")
                                                 {
                                                     Converter = new ValueConverterChain
                                                                 {
                                                                     optionalDictionaryValueConverter,
                                                                 },
                                                     ConverterParameter = new ValueConverterChainParameters
                                                                          {
                                                                              customFieldDefinition.ID,
                                                                          },
                                                 },
                         };

            switch (customFieldDefinition.FieldType)
            {
                case FieldType.Corporation:
                    SetColumnValueConverter(column, customFieldDefinition, corporationIDToNameConverter);
                    break;
                case FieldType.Contact:
                    SetColumnValueConverter(column, customFieldDefinition, contactIDToNameConverter);
                    break;
            }

            CurrentFieldDefinitionColumns.Add(column);
            radGridView.Columns.Add(column);
        }
    }

    protected override void SetColumnValueConverter(
        GridViewDataColumn column,
        CustomFieldDefinition fieldDefinition,
        IValueConverter valueConverter)
    {
        var converterChain = (ValueConverterChain)column.DataMemberBinding.Converter;
        var valueConverterChainParameters = (ValueConverterChainParameters)column.DataMemberBinding.ConverterParameter;

        converterChain.Add(valueConverter);
        valueConverterChainParameters.Add(fieldDefinition.Values);
    }
}

I have a class (ItemTree Parent) bound to a RadPropertyGrid. The class also contains a List of it's own type (List<ItemTree> Children). Is it possible to apply the same PropertyDefinitions for both the parent and children?

GridViewDataColumn Filtering

I have the following code:

<telerik:GridViewDataColumn DataMemberBinding="{Binding CreatedBy.Name}" Header="Name"/>
<telerik:GridViewDataColumn DataMemberBinding="{Binding EventObject.TextData}" Header="User Text"/>

public UserType CreatedBy { get; set; }

public object EventObject { get; set; }

in another class:

public string TextData { get; set; }

In the first column, there is a filter icon, and it filters correctly. However, in the second column, there is no filter icon. Could you explain why this might be and how to resolve the issue?

Multiple instances of the same TabItem

Hi,
We have an issue with tab control and the drop down menu items. Users can create multiple instances of the same tab, that's being displayed fine but when the drop down menu is shown, I can see the names of the tabs, i.e. multiple instances of say "Customer" tab. Now if I select first repeating tab then click on drop down, I can see multiple tabs being highlighted as selected. My question is how can I make those tab items unique so the tab control recognises them as such.

TIA

P.S. please find attached xaml for styling of drop down items

RadDocking PaneStateChange

Hi

I set the PaneStateChange event in RadDocking, but the argument of method is of type RadRoutedEventArgs that is useless because it not contains information about the pane and the state. In https://docs.telerik.com/devtools/wpf/controls/raddocking/events/overview is written that the argument should be ActivePangeChangedEventArgs (that inherits from RadRoutedEventArgs but the cast give me null).

Telerik is 2023.02

Thank you

Insert BarCode inside FlowDocumentEditor

Hi,

I'm trying to add a barcode inside a FlowDocumentEditor.

public static ImageInline InsertQRCode(this RadFlowDocumentEditor editor, string code, double width = 96)
{

    // Barcode
    const double imgWidth = 1000;
    var barcode = new RadBarcode
    {
        Width = imgWidth,
        Height = imgWidth,
        Symbology = new QRCode()
        {
            ErrorCorrectionLevel = ErrorCorrectionLevel.H,
            CodeMode = CodeMode.Alphanumeric
        },
        Value = code
    };
    
    barcode.BeginInit();
    barcode.Measure(new Size(imgWidth, imgWidth));
    barcode.Arrange(new Rect(new Size(imgWidth, imgWidth)));
    barcode.UpdateLayout();
    barcode.EndInit();

    using (var stream = new MemoryStream())
    {
        Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(barcode, stream, new PngBitmapEncoder());
        stream.Position = 0;

        return editor.InsertImageInline(new Telerik.Windows.Documents.Media.ImageSource(stream, "png"),
            new Size(96, 96));

    }

At barcode.Measure, I've got an NullException. This didn't happen with old RadBarCodeQR component.

Any ideas?

Telerik gridview Problem with not being able to retrieve information bound to the cell next to the cell button when clicked

hello
I am Korean, so please understand that I wrote this in translation.

[inquiry]
As the title suggests, there is a problem with my source code and it cannot be resolved.

I am coding in MVVM method.

1. Enter TEXT in “ChangeDetails” [Cell] of [Grid View]
2. When executing the event of “PgmUpCommand”
3. “ChangeDetails” does not lose focus, and the bound “ChangeDetails” value cannot be retrieved.
4. After doing number 1, click another [Cell] in the [Grid] and execute number 2 to get the “ChangeDetails” value normally.

I would appreciate it if you could tell me the solution.

Below is the source

Floating Tabbed DocumentHost

Hi

I have a RadDocking with tabbed documenthost.
If I have only one tab in DocumentHost and I dragged it, the content of the floating window is empty, when I dock again the tab the content is correctly restored.
If I have many tabs in DocumentHost and I dragged one, the content is correctly displayed.

I attached two images that explain the two cases

With 2 or more tabs (correct):
