Hello,

I have a MultiSelect component used to select tags. It works as intended, but I have one problem I can't find any workaround for :

If the user inputs a text that isn't part of the data list, they can't "select" that value, unlike in a ComboBox for example where the data List "guides" you without restricting what you write.

I have found no parameter that allows custom values, and I haven't been able to extract at all the raw text.

To illustrate, here's a screenshot :

I'd like to add / "select" a new value called "newTag" that is NOT part of the data list.

When trying to retrieve the input value from the component (via 2-way binding or onChange event) , I only get a List<string> containing all selected/valid items, in this case a list with only "existing tag".

I can't find a way whatsoever to retrieve that "newTag" text, it would probably solve the problem because then I could work around the lack of custom input permission in the OnChange event by adding dynamically "newTag" to the dataList, thus making it a valid value to select.

Please help me find a way to implement custom inputs.

Best regards

I have an update event but how can I tell the grid the update didn't work out and everything has to be cancelled,

This code doesn't work.

I'm finding the default font size as well as the overall amount of white space around the controls to be a bit much.  I'm trying to produce a much more condensed interface with a smaller font and less margins/padding.

I've been inspecting all of the rendered UI elements in an attempt to figure out the most efficient way to accomplish this but my head is spinning.  So far my assessment is that I'm going to have to do this one component at a time.  And even with that approach I'm struggling. 

For example, I've reduced the font size to 12px but the date picker remains the same size but with the smaller font.  Not quite what I was going for.  

I feel I could spend weeks trying to figure out every single "k-" class that I will need to override.

I was hoping the theme builder would allow me to pick a font size/family as well as options to adjust margins/padding around the elements but that doesn't seem to be the case.

Any suggestions?  Where am I going wrong?

Hi Team,

I have more than 10000 items, after click on TelerikMultiSelect  control it is taking 5 seconds to load the popup. 
Do we have TelerikMultiSelect with Virtual scroll or Paging? 

Hi,

i followed the next example to do serialization of the datasourcerequest on the server:

https://github.com/telerik/blazor-ui/tree/master/grid/datasourcerequest-on-server

when I try to combine this with the grid aggregates, I get this runtime error:

Hi everyone,

Is it possible somehow on a selected row to mark the selected cell when the user clicks on it?

Best regards,
