Hello,

Is posible to override behavior when multiple option is set, to not holding CTRL button to select multiple dates. I want user to use this behavior as default just by normal mouse click on dates.

Thanks.

I noticed that my ModelState becomes invalid if the user doesn't select any value from a cascaded set of dropdowns.  Once you select a value, it becomes valid.  How do I fix this, and actually save my model if the user doesn't actually select anything?  Not selecting anything just means I won't save anything on Post.

thanks

I have requirement to allow editable row for one column in Parent row of Parent-Child Grid. I am able to display field in popup window by hiding all other non required field. But I am getting validation message for hide field while update the required field. Please help me to find out the solution either displays only required field in popup window without hiding all other fields or how to stop validation for non-required field in popup window.

Hi,

Is this also available for ASP.NET Core (MVC/Razor)? Or is this functionality limited to webforms?

https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/filtering/excel-like-filtering/defaultcs.aspx

Thanks!

Hello,

I'm running into an issue where I cannot filter items in a DropDownList when I tab onto it when .Filter is enabled.  When I tab onto the DropDownList I can cycle through items just fine with the arrow keys.

I'm aware of ALT + Down arrow to open up the DropDownList, and that works just fine, but I find that it is more intuitive to start typing once it has been selected, especially when filling out a form. I was wondering if it is possible to have the DropDownList open when it has been selected with Tab, or if there is a way to remap the shortcut.

Hi,

Is there any option for hiding Filter Menu Icon ? I have seen there is a ShowFilterIcon option at Ajax Grid but i think its not available option for ASP.Net Core Grid.

Hi,

We want to use the .net core scheduler for people to define their availability online.  This maybe as single meetings or a reoccurring meeting.  This will probably use the standard web api and db schema used in the telerik examples.  What I then need is a helper function that will return me all the periods of time a single user is available in a given week.  I have read elsewhere that recurrence is client side only and that a library such as ical.net is needed to load/cast the data and then interpret it using its functions.  However I see in this telerik example there is a class that seems to do this:

https://docs.telerik.com/devtools/aspnet-ajax/controls/scheduler/server-side-programming/working-with-recurring-appointments

Before I go down the ical.net path can someone confirm if there is standard telerik SERVER code to get back dates from recurring meetings saved by the schedule and maybe provide more details or an example?

Thanks, Matt
