Hi

Where can i change the text (content) color of a RadNavigationViewItem?

I figured out how to change color of everything else except the text color.

I tried to set foreground color RadNavigationView and RadNavigationViewItem

and i cannot see a style i could set to fit my needs.

Please let me know where i can set the color or if i am just blind :)

Thank you in advanced!

Cheers,

Mats

I simply dragged the RadComboBox control from the Toolbox under "Telerik UI for WPF - Input 2020 R3" and dropped it into the designer.  This created the entry:

<telerik:RadComboBox/>

I did nothing else, build and execute project and when this Window comes to load I get a runtime error:

System.Windows.Markup.XamlParseException
  HResult=0x80131501

If I remove the <telerik:RadComboBox/> line, execution works.

I must admit, my success rate at using Telerik UI for WPF is pretty low, I've spent many hours researching really basic problems and hoops to jump thru to get things to "sorta" work.  I don't know what the object is with Telerik UI for WPF, but as it stands right now, it's NOT improving productivity, just the opposite.  

I'm at the point where I'll just go back to using all the default VS 2019 Microsoft controls because they just work.  My Telerik renewal is coming up in Nov and I honestly can't justify renewing.

Hi,

In the documentation of Shape Tool https://docs.telerik.com/devtools/wpf/controls/radimageeditor/tools/shape-tool it says that: "The Shape Tool provides an options to easily customize your shape – you can choose if the shape will be filled with some color or it will consist only of borders, which color and thickness also depends on your preferences. You could take advantage of the LockRatio property, which will ensure that the proportions of the shape will be always the same when resizing.".

But I don't have these options in my ShapeTool() or in my RectangleShape() object (I execute tool commands by code).

Where can I set a border color and a thickness in rectangle shapes and the same for a custom shape tool by code? (I don't use the option panel displayed on right).

Version of my telerik controls: 2019.2.510.45

Thanks in advance for your reply.

In our project we have updated Telerik UI for WPF to version 2020.2.617.

So, the existing Telerik dlls (NoXaml version) were updated via Nuget Package manager to 2020.2.617 version. 

However when I have updated the theme xaml files, I got the following errors:

As from the error I can see that `ThemeType` resource is missing and that is why application is crashing at runtime.

After investigating a bit I wasn't able to find this resource inside xaml files, which means that it is probably in some dll which is missing from the project.

Will much appreciate for any support!

Hi,

How can set text wrapping for the the displayed text of the MultiColumnComboBox control in XAML ?

Hello

I have a cartesian chart that includes a barchart, which range is fixed and unique, and I have dynamic line series, which are user defined at run time (see attached screenshot).

Each lineseries is bound to a business objects that contains three properties: Color, which will be the color of the series, Code, which is a string that identifies the series, and Coll which is a collactiion of dates + decimals that make the series.

When I add the trackball functionality, I can see the bound values, but I would like to add the Code identifier, as otherwise user cannot tell which is which.

Thanks

Herald

Hello.

I use RadGridView (2018.1.116.45).

I am create columns and set him binding in programm code as 

column = new GridViewDataColumn
                {
                    ColumnGroupName = args.ColumnDef.ColumnGroupName,
                 
                    DataMemberBinding = new Binding(args.ColumnDef.Member)
                    {
                        Mode = BindingMode.TwoWay,
                        UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged
                    },
                    IsReadOnlyBinding = new Binding(args.ColumnDef.IsReadOnlyMember)
                    {
                        Converter = new NullToBooleanConverter {IsInverted = true}
                    },
                   
                    Header = args.ColumnDef.Header,
                    IsVisible = true
                };

If i set cell value from UI all right, but if i set value from code UI not update, only after i select cell and try input value, value which i set erly will be placed in UI cell.

I try update view by programm code as

 var oldCellInfo = MainGrid.CurrentCellInfo;
            var gridViewCellInfo = new GridViewCellInfo(sender, gridViewColumn);
            MainGrid.CurrentCellInfo = gridViewCellInfo;

            MainGrid.CurrentCell?.BeginEdit();
            MainGrid.CurrentCell?.CommitEdit();
            
            MainGrid.CurrentCellInfo = oldCellInfo;
            MainGrid.CurrentCell?.BeginEdit();

            MainGrid.UpdateLayout();

But this is not working...

How i can update UI?

Hi community,

I am using the current trial version of Telerik UI for Wpf.

I can not find getters to get a cell value of a calculated column, programmatically. Is there a way to find a simple cell value.

- Documentation of the RadGridView :

if ((decimal)radGridView1.Rows[0].Cells["UnitPrice"].Value > 10)

     radGridView1.Rows[0].Cells["UnitPrice"].Value = 10;

But when I try radGridView1.Rows... I have the message "No definition for Rows..."

So i can not use the documentation code

Thank you

I've been searching here and any other websites that show up in a search online for anything that seemed answer my question but haven't seen anything yet.

I'm looking for a way to prevent appointments from being automatically selected when they have been updated. My appointments are removed and re-added to their collection, which appears to be the only way to successfully update the UI per this forum. I think it was this post I found, for those who are curious - https://www.telerik.com/forums/update-ui-after-collection-of-appointment-change

My problem is this: background logic is updating appointments and when using the schedule the appointment selection is constantly changed to the last updated appointment. This makes selecting and interacting with other appointments difficult. I won't rule out that my implementation may be incorrect, but I believe I have done well so far thanks to this forum.
