Hello,

I've been trying to enable drag and drop functionality so that the user can sort the RadNavigationView menu items, and it works when the ItemDragMode property is set to Preview, but does nothing when it's set to Immediate, then there's no drag and drop at all, the functionality seems to be disabled.

c.ViewElement.ItemDragMode = PageViewItemDragMode.Immediate

I'm not sure if I'm doing something wrong, or if this is the intended behaviour (so the immediate mode it's not a supported feature), or if it's just a bug.

Thanks

Hi Telerik support team,

I’m strugling with the Winforms GridView GroupComparer and need some help with it. I’ve seen the topic below:

https://docs.telerik.com/devtools/winforms/controls/gridview/grouping/sorting-group-rows

In my case I’ve a generic comparer in which I want to evaluate which column needs some sorting changes. These are my unitColumns and I have a reference to its list at the moment I create the comparer.

this.radGridView1.MasterTemplate.GroupComparer = new CustomGroupComparer(list);

The problem I walk into is that Telerik creates new CustomGroupComparers by itself (I think for every group?). It also demands an empty constructor. This way I have no option to get to the list that I need.

Is there a workaround for this problem?? For this moment I defined a hardcoded List inside the customComparer but that’s not the way to program it.

It would be nice if the custom comparer was part of the GroupDescriptor.

Regards,

Daniel

I'm trying to unregister a tagger for an radSyntaxEditor.  I've applied a tagger previously and want to change it.  So far, it appears that I'd have to save which tagger was used prior, and then unregister it that way?

Meaning, there's no way (that I could find) to get a list of applied taggers.  All of the methods assume you already know what is applied.

I guess you could create an object of each type of tagger and then check for every possible tagger and then remove it, but...

Basically, what I was expecting was either a way to get a collection of the applied taggers, or be able to call the UnRegisterTaggers without parameters to remove them all, etc.

Any help would be great!

According to this page: https://docs.telerik.com/devtools/winforms/controls/menus/contextmenu/context-menus

I should be able to assign a radcontextmenu to the contextmenu of the radsyntaxeditor.  However, I'm finding that not to be the case as you can see below.  my contextmenu named ctxMenuEditor is of type radContextMenu.  

The below screenshots should show the problem I think.  Basically, for whatever reason, the radsyntaxeditor doesn't accept the radcontextmenu, just contextmenu object type. 

Hi:

I have a Winforms application that I recently update the Telerik controls to 2023.1.117.40.

I am now unable to build as I am getting the following error:

'Could not load file or assembly 'Telerik.WinControls.Themes.Crystal, Version=2023.1.117.40, Culture=neutral, PublicKeyToken=bf4391287131aaeb' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)'

Am I missing a required Telerik library in my references?

Here are the libraries I am currently referencing:

There seems to be an extra row created, w/ no data after the last row of data is added to the CSV.   Not sure what is happening or if there is a setting to not include the last empty row.  Just so we are clear, I have a grid with 10 rows in it, but when I look at the csv that is generated from the grid, I have 11 rows.   

When I add a new document window as such: docContainer.DockManager.AddDocument(newPage)

The tabstrip that it is created on, the new tab always appears first in the tab list.  I'd like it to appear on the end of all current tabs (the right in my case).  I can't figure it out, any help would be appreciated!

Is it possible to select (highlight) individual lines in a RadTextBox when multiline is set to true?  For example, a user enters 10 lines of data, is it possible to highlight only lines 2, 5, & 7?  If so, how?

When I use filter in gridView it is OK

I see to xml file

with radFilterView I get:

<FilterDescriptors>
      <Telerik.WinControls.Data.FilterDescriptor PropertyName="Modul" Operator="IsEqualTo" Value="MyValue" />
    </FilterDescriptors>

with filter in gridView I get:

<FilterDescriptors>
      <Telerik.WinControls.Data.CompositeFilterDescriptor LogicalOperator="Or" NotOperator="False" PropertyName="col_Modul" IsFilterEditor="True">
