TypeAccessException occurs in .NET Framework projects when using internal class for the data point models. The error doesn't occur in .NET 8 projects.

To work this around, upgrade the target framework of the project to .NET 8. Or use the GenericDataPointBinding class for the binding properties of the series (XValueBinding, YValueBinding, etc.), instead of the default PropertyNameDataPointBinding.
The selection a RadComboBox hosted in RadDataForm gets cleared on commit changes. This happens when the RadComboBox is added in the EditTemplate and its IsEditable is set to True. Committing the edit clears the TextBox of the ComboBox, which clears the selection.
To work this around, subscribe to the EditEnding event of RadDataForm and clear the DataContext of the RadComboBox element.
private void RadDataForm_EditEnding(object sender, Telerik.Windows.Controls.Data.DataForm.EditEndingEventArgs e)
{
var dataForm = (RadDataForm)sender;
var myField = dataForm.ChildrenOfType<DataFormDataField>().FirstOrDefault(df => df.Name == "myField");
if (myField != null)
{
var comboBox = (RadComboBox)myField.Content;
comboBox.DataContext = null;
}
}
i have UriVectorTileMapProvider and i have files pbf.
When i create my style file json i cant get render corectly.
i have two example:
1)one in my style json i have three layers:buildings,military,hospital (ex1.png)
When I use such a file, one polygon is lying with buildings on top where the other polygon covers the buildings
"layers": [
{
"id": "landcover_wood",
"type": "fill",
"source": "openmaptiles",
"source-layer": "landuse",
"filter": [
"==",
"class",
"military"
],
"layout": {
"visibility": "visible"
},
"paint": {
"fill-color": "green"
}
},
{
"id": "landcover_hos",
"type": "fill",
"source": "openmaptiles",
"source-layer": "landuse",

whats wrong with my json file style?
Bind a grid to a DataView
Start editing and change the values of a few cells.
Press Escape twice to cancel the edit of the entire row.
Expected: the values return to the old values
Actual: the values remain the last entered ones
Can be reproduced in the WPF demo (Windows8 theme): the error description tooltip appears on the left of the control and with the red arrow on the left (see attachment). The tooltip should appear on the same side of the red adorned element (the red triangle, top right corner) and the tooltip arrow should point the control.
When biding IsVisible of column in RadMultiColumnComboBox/GridViewItemsSourceProvider using MVVM pattern, the binding won't work initially, but is works as expected if removing the ElementName and adding it back in the below example xaml using debugger.
PS1. The binding for CheckBox(in the below sample) works with issue but not for RadMultiColumnComboBox
PS2. Also attached full sample code.

Hi Telerik-Team,
i found a bug similar to forum post, but not the same.
In MultiColumnComboBox when SelectionBoxesVisibility is set to 'collapsed' and and whatever you set AutoCompleteMode to (different from the forum post),
if you select the first item it is not shown. Although the NullText is removed. It works perfectly for all the other items. This is quiet a problem if you only have one item in the dropwdown :D
Regards,
Mats
RadMaskedNumericInput Maximum value setting is not working with hungarian culture settings.
Steps to reproduce:
- Open the attached project, fix the references and start the application
- Click button "English"
- Select the first item from the dropdown
- Inputs are changing to 1433.2 and 1810.9 - OK
- Select the 2nd item from the dropdown
- Inputs are changing to 0 and 59 - OK
- Click button "Hungarian"
- Select the first item from the dropdown
- Inputs are changing to 1433.2 and 1433.2 - NOT OK, Why?
Thanks,
Roberto
When filter is added to merged cells, there should be a single filter icon displayed in the combined cell. Instead, multiple filters appear - one for each column in the range of the merged cells.
The issue is reproducible only on Windows XP. On newer versions of windows, the images are rendered as expected.
WORKAROUND: You may inherit DctDecode class in order to implement custom decoder. For instance, you may try calling DecodeWithJpegDecoder method from the base class as mentioned in the note of this documentation article:
http://docs.telerik.com/devtools/wpf/controls/radpdfviewer/customization-and-extensibility/customize-pdf-rendering
A sample implementation of these custom decoder may be seen below:
public class CustomDctDecode : DctDecode
{
public override byte[] Decode(PdfObject decodedObject, byte[] inputData, DecodeParameters parms)
{
return DecodeWithJpegDecoder(inputData);
}
}
The RichTextBox internal logic that imports .docx documents (DocxFormatProvider) doesn't support elements that don't need direct content, but have both start and end tags. Instead such elements should use self-closing tags.
For example, instead of <w:vertAlign w:val="baseline"></w:vertAlign> it should be <w:vertAlign w:val="baseline"/>
When such element is read during import, issues may occur. Two main known issues here are with the w:vertAlign and Relationship tags.
Using
<w:vertAlign w:val="baseline"></w:vertAlign> instead of
<w:vertAlign w:val="baseline"/> throws NullReferenceException with the following stack trace:

To work this around, import the document with the WordsProcessing library. If you need to display it in RadRichTextBox, you can export it again using the WordsProcessing library. This will normalize the tags. Then import it again using the RadDocument's DocxFormatProvider.
var dplDocxFormatProvider = new Telerik.Windows.Documents.Flow.FormatProviders.Docx.DocxFormatProvider();
RadFlowDocument flowDocument = dplDocxFormatProvider.Import(File.ReadAllBytes("../../../test.docx"), null);
var docBytes = dplDocxFormatProvider.Export(flowDocument, null);
File.WriteAllBytes("../../../modified-doc.docx", docBytes);
var rtbDocxFormatProvider= new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
RadDocument document = rtbDocxFormatProvider.Import(File.ReadAllBytes("../../../modified-doc.docx"));
Pressing the Enter key when a field editor is focused will scroll the vertical scrollbar to the topmost offset. This is reproducible when the properties are grouped. Also, the RenderMode should be set to Flat.
To work this around, change the RenderMode setting to Hierarchical right before the Enter key logic is executed and then return it back to Flat after some time.
private void RadPropertyGrid_PreviewKeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
var propertyGrid = (RadPropertyGrid)sender;
var currentMode = propertyGrid1.RenderMode;
propertyGrid.RenderMode = RenderMode.Hierarchical;
Dispatcher.BeginInvoke(new Action(() =>
{
propertyGrid.RenderMode = currentMode;
}));
}
