How to set the Header text 'HeaderDay,HeaderMonth' without using resx files

i would like to set the text of the the "Day/Week/Month/Year"-Buttons in the top right corner

Can this simple be done in code behind without using a resx file as I've already have a custom localization provider linked to a database

i.e. GanttChart.ToolbarButtons[0].text = "test"

DropDownTree Set Selectable Property

I am using the DropDownTree to display nested items. Sometimes parents are selectable, sometimes they are not.

In the dataset being returned, I have 3 columns: Text, Value, IsSelectable.

Is there a way to pass the IsSelectable property through to the DropDownTree and then make the items selectable based on that property? It seems like it only takes Value and Text.

Please let me know if there is a way for this to work! Thank you!

Hello Telerik-Team,

Could you tell me, how I can change the title text of the time selection?
I want to translate it to my language. I added a screenshot, where I marked, what I mean.

Radgrid in master page does not update when the form template is contained in the content page

Hi,
I have a master page with a grid that inherits the form template from a content page. The fields are displayed correctly in edit and all valued but when I press update it says that the fields cannot be null.
This problem occurs only if the form template is on the content page while if you put the template directly on the master page then everything works.
I used a code similar to the demo https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/form-template-update/defaultcs.aspx as an example.
What I do wrong and how I can fix it?
Thanks
