Hello,

I've searched for a while but didn't find anything useful about it.

I've a dataset, filled with an SQL query which contains a table of many records, and a gridView with a comboboxcolumn. I try to bind my comboboxcolumn with my dataset, but it only displays the first row, in my whole column. For example, if I have 400 records, it displays 400 times the first record.

Here's my code in my .xaml :


etc, and :


And in my .cs :


Did I miss something ? And yes, I'm sure that my dataset is filled with the right values.

Thanks for your help !

Hi Team,

We are trying to automate actions on ListItems present in filter properties window of Rad Grid View with VS2012 Coded UI Test Framework but we arenot successfull in it.
Name property on the listitems is used for its idetification but this name seems to be same for all the list items present in the list(i.e. "Telerik.Windows.Controls.GridView.DistinctValueViewModel").

Can you please implement ToString on the listitems to consider CheckBox name[which is present inside the listitem] ?

Regards,

I've run into an issue where GridView will freeze when trying to auto-adjust column widths to the available window if a group is applied. I have a series of columns, most of which are Width="Auto", but one of which is Width="*". If I resize the window to allow the * column to expand, then try to reduce the width while a grouping is applied, the horizontal scroll bar flashes and the application freezes. Sometimes it comes back, sometimes it doesn't. Sometimes switching to another window and back seems to help, sometimes it doesn't.

Pausing the debugger while this is occurring (which is only possible some of the time; sometimes Visual Studio is frozen as well) tries to open the file:

c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Controls\GridView\GridView\GridView\ScrollViewer\GridViewScrollViewer.cs

The call stack is:
[External Code]
Telerik.Windows.Controls.GridView.dll!Telerik.Windows.Controls.GridView.GridViewScrollViewer.MeasureOverride(System.Windows.Size availableSize) Line 202 + 0x25 bytes    C#
[External Code]

The problem does not occur if the * column is switched to Auto, or if the Grouping is not applied. It also doesn't seem to happen if no vertical scrolling is necessary.

I am using 2013_3_1209, but have verified the problem still occurs with 2014_1_0224. Below is a simple application which exhibits the problem when you try to reduce the width of the window.

Is there any known way to work around this issue using other settings while achieving the same effect?

I'm trying to change the series color in both PolarSeries and CartesianSeries charts (in C#)... in neither can I find the Appearance, Definition, Stroke or Fill properties mentioned in the documention, any clues how to achieve this?

Tia,

Can someone explain how to bind to the SelectedDates property to my view model?

It is not exposed in the XAML designer, why is that?

Hello,

I am using a RadRichTextBox as HTML editor (I use HtmlDataProvider for that)

In my xaml View, i got :  

                                     - A RadRichTextBoxRibbonUI (with only 6 RadRibbonGroup useful for HTML) and its QuickAccessToolBar
                                     - An HTMLDataProvider and its settings
                                     - A RadRichTextBox 

In my Controller the first call of InitializeComponent();  takes about 8 seconds to load the page (it is rather long)

It's only the first call (after that this is cached). I think, it's not possible to construct all of this under 3 seconds.

So I decided to implement a loader for my users. 

But due to WPF limitations (MTA thread, ...) it's pretty tough to do that. Have you an example of loader? An other solution?

An other issue is on old computers : it takes a long time when typing on keyboard in the RadRichTextBox (I already disable some features to improve that)
Have you a list of all the things which can slow the RadRichTextBox typing?


Features : 

1) How to draw a line (<hr>) in an HTML Editor ? I didn't found any buttons in the Ribbon to do that 

2) How to open an HTML document with relative path image? Images are considered as bad images


Regards,

 

I added a 2nd TextBlock to DataTemplate for my RadLegeng on my RadCartesianChart:

 
I would like to add custom attribute to bind (Percent) to said 2nd TextBlock through binding and with named declaration of LegendItems:


Through searching, I wasn't sure how/if I can add on a new attribute to the LegendItem schema for the custom binding.

What am I missing? Any help or direction would be appreciated.

DataConext binding for my RadContextMenu is being ignored. My menu is defined like this:



It works if I define it like this:

But this version displays a menu within a menu.

How can I get DataConext assigned on the outer menu?

Hi,
