See attached picture together with these steps.

  1. select a item in the list
  2. import multiple other items in one go -> the last imported item is marked as selected (this is OK), the previously selected item is no longer marked as selected (this is OK).
  3. SHIFT select the first item of the ones imported in step 2 -> the items between the last imported item and the first imported item are selected, but the item that was selected in step 1 is now also selected...

 

Thanks in advance!

Bart

Hi Team,

 

We have a business case, where we build a spreadsheet with collapsable groups and subgroups. Our customers wanted to have an overview about the group totals on each group and expand and collapse the groups on demand (because it's also possible in Excel).

 

So, it would be awesome, if you could extend your spreadsheet component with that feature as well.

 

Thank you

We have a WCF service that continuously polls a database for new/updated items and sends them to WPF clients.  The client will process the update, decide what to do and then add/update an item that is displayed in a RadGridView.  We use an IEditableCollectionView on top of an ICollectionView.  Exception detail is below.

App just crashed while sitting idle on Zarate,

No mention of MSCORLIB so I think its a different error.

I'm using the fluent theme in my app. When I load ColorVariation.Dark, everything is dark except a sub-window. This is a window created by my main window. Its main control is TabControl with most of the tabs items being ListBoxes using data templates. The Listboxes display dark but the window itself is light along with the first tab item which is just a grid with TextBoxes. I don't specify background color on any of these controls so I assumed they would come from the theme. Do I have to do something to pass the info th a sub-window?

I would like the fluent theme to support spacing option like it does fonts. The Mail app added a new setting "Folder and message spacing" in which you can pick spacious , medium, or compact. I would like the fluent theme to support something similar.  The fluent theme was defined for "finger" access but we still have desktop apps that want dense information with mouse access.  I would normally just pick a different theme but because of Windows 10, I can't. Windows 10 no longer supports specifying a default font and WPF no longer defaults to the OS font. This means that all my Windows apps must support picking a font. So I'm stuck with the fluent theme. But I don't always want the "spacious" spacing that the theme uses.

Would it be possible to support picking "spacious", "medium" or "compact" spacing?

Please add a feature for justifying the bar series chart so that bar data points can be plotted with a "Left", "Right", or "Center" justification to chart ticks.

An image to describe a "Right" vs "Center" bar justification is provided.

Short version of feature request: 
It would be nice to be able to enforce unique value in a column in an MVVM environment?

Long version of request:
To enforce a unique value in a column I ended up with a custom ValidationAttribute in the data model. Very much like the last example in the old thread 
https://www.telerik.com/forums/force-validation-on-new-record-insert

Direct link to the example provided by Telerik:
https://www.telerik.com/clientsfiles/375715_328546-TestApp-new.zip 

At a first glance, the solution seems to work, but if you edit a value in a cell and the new value is the same as another cell in the same column, BOTH these cells would have an error. Not just the cell you edited. I understand that not all cells can be validated whenever a single cell is edited, but it would nice if there was way to configure the RadGridView to “refresh” validations of all visible cells when a validation error is either set or removed?

I do not know if a solution like this would fit the internal design of the RadGridView, but it might give you some inspiration :-)

Add an attribute to the column definitions in the GridView:
ValidationTransitionMode= Default | ForceValidationOfAllVisibleCellsInColumn | ForceValidationOfAllVisibleCells

Default: 
No change from existing functionality.

ForceValidationOfAllVisibleCellsInColumn: 
Whenever a validation result of a cell changes (from no_error to error OR from error to no_error) all the visible cells in the column will be re-validated. This would do the trick to enforce uniqness in a column with a custom ValidationAttribute.

ForceValidationOfAllVisibleCells: 
Whenever a validation result of a cell changes (from no_error to error OR from error to no_error) all the visible cells of the complete grid will be re-validated. To be used by people with more complex validation algorithms depending on values in other columns as well.


Steps to visualize the current problem.
◦Run the example (https://www.telerik.com/clientsfiles/375715_328546-TestApp-new.zip )
◦When the application is running, reduce the window height (from the bottom) so that the scroll bar is visible and the top visible row shows “last name”=”Rockhead 0” and the bottom visible row shows “Rockhead 4”.
◦Change last name “Smith 3” to “Smith 1”.
◦Now there is a red border around the cell we edited (as expected) but nothing happens to row 2 (First name=Jane1).
◦Scroll to the bottom and back up to the top.
◦Now there is also an error on row 2 (First name = Jane1).
◦Change “Smith 1” back to “Smith 3” (on the row where First name=Jane 3).
◦The error on the cell edited is now removed, BUT the error on row 2 (Jane 1) is still visible even as all values in the Last name column is now unique.

I got some very good support and a suggestion to modify the control template, but it would still be nice to be able to control the validation execution of cells, other than the current cell.

I would like to do a Backstage design without writing code, the syntax of XAML is confusing and I do not understand it well, besides being slow, the development of software at design time is always much faster.

I am attempting to use a ReleativeSource in my bindings in two places in a RadGridView:  1) the header of a column, and 2) one of the columns.  I am getting "System.Windows.Data Error: 4 : Cannot find source for binding with reference" in both cases.

I don't think I need to elaborate much, since https://www.telerik.com/forums/can%27t-find-the-right-ancestor-to-bind-to not only describes it perfectly, but also contains sample code from Telerik that, on my machine, fails the same way.

Hi,

I have implemented a WPF application that displays various pages.

I have the following code that is executed on one of my pages after a user logs in. This same code is executed when the user returns to the page:

If myUser.IsInRole("Master") Or myUser.IsInRole("Administrator") Then
            myRadGridView.SelectionMode = SelectionMode.Multiple
Else
           myRadGridView.SelectionMode = SelectionMode.Single
End If

After logging in the myRadGridView grid behaves as if it is SelectionMode.Single even though my user is in the role "Master" and the code branch above is executed to set the myRadGridView grid into SelectionMode.Multiple.

That being said, if I leave the page and come back to it, the same code is executed and the myRadGridView grid finally behaves as it should be in SelectionMode.Multiple.

How do I fix get this to work?

Thank you.

Affects RadDateTimePicker control of TelerikWPFControls version 2015.1.1

When the user is typing in a specific date and time, the RadDateTimePicker control's text-to-date parsing doesn't accept an uppercase 'A' at the start of what it expects to be the month's name and automatically errors (displays a tooltip showing 'Error') as soon as an 'A' is input. This prevents the user from entering dates and times more specific than the clickable selection for the months of 'April' and 'August'. However, replacing the 'A' with a lowercase 'a' allows the user to proceed with entering more specific dates and times as normal without the 'Error' tooltip showing. 

E.g.: 
1) the user selects 03 April 2018 17:00:00 from the control's clickable selection of date and times;

2) they then try to type more specific minutes and seconds, e.g. 03 April 2018 17:45:23, but this is not accepted by the control and it displays the 'Error' tooltip;

3) workaround - the user changes 'A' of 'April' to a lowercase 'a', as in 'april'. Now the 'Error' tooltip goes away and the user is able to enter and save the more specific date time of 03 april 2018 17:45:23.

This bug only came to light once the control was live in production (released in January) and prevented our users from entering the specific trade date times necessary for regulatory purposes.

Can you tell me if this bug has been fixed in later versions of the control?

Thanks and regards,

Robert Fiteni
