Hi
I attached a simple program that import a html file (with format and images) and export it.
The exported file is very different from the original, without format and without images.
Thank you

I am using filtering with a custom DataProvider for my Virtual Grid. Users use the popup dialog to set filter conditions. It works well.
I understand how to retrieve the filter descriptors from one grid and to apply them to another. But how may I persist them?
I want to save to a text file a set of filters from VirtualGrid A. Then, later on, I wan to set VirtualGrid B columns to to use those same filters purely from that persisted text?
I can see that ColumnFilterDescriptor.ToString() will give me what looks like a full persistable filter expression. At least it looks like a meaningful expression. But I canntot see a method to go the other way

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);
}
}
Kind regards
Benny

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?

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?

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 <Style TargetType="Telerik_Windows_Controls_TabControl:DropDownMenu" x:Key="DropDownMenuStyle">

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
Luigi
