In the spreadsheet control you cannot link/use in a function cells from one work sheet to cell(s) in another work sheet. Would like to have the same behavior and functionality of Excel, which allows you to use data from one sheet in any other sheet in the work book. Need the ability to create a sum of (or any other function available) cells from another worksheet in my current worksheet, within the same workbook.
You have to add next features to RadMaskedNumericInput
- Data binding to object
- Value could be decimal
- Value range, from min to max,
so this control could be useful in complex data entry form.
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.
It would be nice to have some additional public properties and commands for ExplorerControl. For example:
Thanks for your consideration!
Unlike Bing Maps, Azure Maps allows for traffic tiles to be rendered over top the standard map tiles. Please bring the traffic layer back with Azure Maps Traffic Tiles!
With a picture of original size like this : width 2 800 and Height 1376. On the screen the picture is around 470 by 230. If I go to the Image Editor, it shows me the picture size itself but not the area size used by the picture. It is a good thing to have the original picture's dimension but we work with the dimension used in the document. So, could you do something to resize the picture used in the document.
In my samples, you'll see my picture in a document (ie1), what I see when I go in the Image Editor (ie2) and, when I go to the Resize section (ie3). Suggestion, put the original image's dimension on the top of the right corner in the resize section. The width and Height should show the dimension in the document.
Thanks a lot,
Having Problems with unreadable Tabs in RadPaneGroup: TabsSqueeze.png
I think I found a Solution with OverflowMode and ScrollViewer:
<telerik:RadPaneGroup x:Name="DocumentGroup" ScrollViewer.HorizontalScrollBarVisibility="Auto" OverflowMode="Scroll">
After Loading Layout the OverflowMode is not respected anymore.
I found this ticket in Silverlight, what discribes the Problem and is approved: Docking: I would like OverflowMode to work for all RadPaneGroup in xaml/codebehind and this be persisted through SaveLayout/LoadLayout
And i found this documentation, which say, using OverflowMode can lead to unexpected behaviors:
so i report this as a feature instead of a bug.
Please sea atteched an example project: TabWrapProblem.zip
Usage: Save and than Load the Layout -> Scrolling of tabs break
the display of the drop-down part of the multicolumncombobox is different from the RAD combo box. There is an extra line between the content of the combo box and the drop-down button in the office 2016 theme at least. This should not be there to be consistent with the other combo boxes.
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?
Currently, the control relies on its IsLoaded property to determine if it should render its items (axes, data points, annotations, etc.). However, if you measure and arrange the control in code without adding it into the visual tree, the IsLoaded property is not set to True, therefore the chart is not rendered and the image gets empty. Original description ---------------------------------- Title: RadCartesianChart incorrecly rendered We're rendering (Telerik) charts in code behind, to include them in a dynamic documentation. For most controls it works fine - using standard methods (rendering control with System.Windows.Media.Imaging.RenderTargetBitmap and saving the result BitmapSource to disk) However, it's impossible with RadCartesianChart with CategoricalSeriesDescriptor or ChartSeriesDescriptor. What we are able to get are axes and descriptions, but not bars. I'm attaching an example - MainWindow displays a chart. I try to also create the chart in code behind. In CreateAndSaveChart() method I create a chart with a DataContext, then I call Measure and Arrange methods on it. At this stage the control should be properly initialized and ready to render. (For simplicity I omit rendering control with RenderTargetBitmap - you can preview the control with WPF Tree Visualizer, which will give you the same result). Well, if you preview the control at this stage, you'll see that the chart is missing bars. Next I create a new Window with my chart as a content, and display it for a while. Now the chart is fully and correctly rendered. As a workaround we display some Telerik chart in a transparent window to fully render, but such a workaround was reported not to work for some clients and is unacceptable in a long run. With most of Telerik charts we don't have such problems. Other issue: - for other Telerik charts we need to wait a few seconds to have it fully rendered. It's be better to have an event informing that the control is ready. I'll be happy to add more details if you need any. * While experimenting with the example I've suddenly managed to render the chart with bars, but this time the rendered size was incorrect (very small)
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.
If you set IsEnabled = false, in the RadComboBox then (in the Office 2016 theme) the entire box is faded, including the text. A suggestion in the forum was to set IsHitTestVisible to false, as well as IsTabStop. This works, but it means that the dropdown button still looks enabled. It would be nice if IsReadOnly did what I wanted, but it doesn't. Therefore, either a way to set the Visibility/Opacity of the dropdown button. Or alternatively, modify the theme(s) to make the text more visible when the box is IsEnabled is set to false, in the same way as the standard ComboBox. I'm aware that I can modify the template myself, but it'd be nicer if it was built in.
