Property change notifications in Intersection PropertySetMode

I have noticed that when using Intersection PropertySetMode that property change notifications from Objects in the List of items are not used by the property grid. Is this a known limitation or a bug?

I am using version 2015.2.728.

PropertyGrid.PropertySetMode = PropertySetOperation.Intersection;

PropertyGrid.Item = new List<Object> { myObject1, myObject2 };

// Property change notifications from myObject1 and myObject2 do cause the property grid values to update.

Pdf viewer crashes before image from scanned PDF is rendered

I am loading a scanned PDF in the PDFViewer and if I navigate away from the page that is loading the pdf before the image of the pdf is finished rendering it causes the following exception: "The given key was not present in the dictionary"

I believe the exception comes from ImageLoader_WorkCompleted method from the Telerik.Windows.Documents.Fixed dll.

How to create TabControl Having Close Image Button

Hello,

I have downloaded and install a very beautiful Telerik winform application. I found a very nice tab control (We say probably radpageview to it in winforms) with a little close image aligned at right side. I am really impressed and want to create it in wpf. Telerik TabControl doesnot fullfill this behavior by default. I actually need to implement it dynamically when a user click on button. For example when a user click on button a tab control should be created dynamically as you can see in attached image.

I want to achieve this by using mvvm/xaml pattern using as much as simple example code. If you please send a sample project with complete code implementation i will be really glad and thankful.

you are using unsupported command line flag --disable web security error

Hi,

I'm seeing this "you are using unsupported command line flag --disable web security" error message in Chrome (Version 46.0.2490.86 m), which appears to be coming from Telerick's Test Studio plugins, as I don't see them when those are disabled.

Is there a way to get rid of that error message?

Thanks,

Arcady

Barcode Reader

I've been playing with your Barcode Reader and assume I am doing something wrong or missing something.

First, is there a way to "push the Open button" from the library? When I produce a barcode image, I'd like to just have it read that when I ask in code... not from the button.

Secondly and more important, I can't get a good read. I have created a demo app that I'd be happy to share. I print a 128 barcode to PNG file. Then, I attempt to read the value back using the reader and it never returns the value I entered into the barcode.

Output Barcode to PNG File:

SaveFileDialog dialog = new SaveFileDialog()

{

DefaultExt = "png",

Filter = "png (*.png)|*.png"

};

if (dialog.ShowDialog() == true)

{

using (Stream stream = dialog.OpenFile())

{

Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(

barCode,

stream,

new PngBitmapEncoder());

}

Let me know if you want me to upload my demo app.

Incorrect editors when switching PropertySetMode

I'm experiencing some odd behavior when changing the PropertySetMode at runtime.

I have two object types: MyTestClass1 and MyTestClass2. MyTestClass1 has a writeable property IntProp and MyTestClass2 has a readonly property IntProp. If I start in Intersection mode with Item = List<Object> { myTestClass1Obj1, myTestClass1Obj2 } everything works properly. If I then change to PropertySetMode None with Item = myTestClass2Obj, the editor for IntProp will be writeable even though IntProp on myTestClass2Obj has no public setter.

See runnable test case below. I am running 2015.2.728
