When I enter text in a textbox in a dialog, if I type too quickly some characters are dropped and if I press and hold the backspace key to remove entered text, it all goes a bit crazy and the cursor bobs back and forwards, deleting some characters and then adding some back again.
I was testing while running through the RadzenCRM step by step documentation.
I am using the latest version of Radzen (as of todays 2.30.1 update) on Windows 10 and have tried it in Chrome and Edge browsers with the same result, however if I try the demo app at https://crm.radzen.com/home it doesn't happen. Same for the blazor components demo, doesn't happen there either.
It only seems to happen with text in a modal dialog.
What's going on here? Is it something local?
I don't recall it happening in version 2.30.0 but that is not to say it wasn't happening.
I have been trying to grab some more info, it only seems to be the case in fields that I have edited/added through the migrations as described in the CRM tutorial. The original fields seem to be fine.
For example the fields shown in image attached below.
I am sorry but I do not understand what the problem is. Where are you typing? Is it in Radzen or in the running application in the Browser? What text field?
It is happening when I run the application (chrome or edge). I log in (admin/admin), add a new user and the dialog that has been amended as per the previous screenshot pops up.
I type the new users first name or last name and anything other than typing at a snails pace, shows the problem with the keystrokes being typed into the running application being eaten.
I thought it might be the autocomplete, which was checked by default because I copied the email field as shown in the CRM tutorial, but when I try to uncheck the checkbox, I get a casting error, so uploaded a quick video showing that issue too.
Arggh. the problem with the autocomplete has now broken the build.
When I click on the add users now I get in the output window the following exceptions and the dialog does not show now.
Do you want me to start a new thread as this is a different problem?
Mark.

We reproduced the issue and will experiment with a solution - it seems that Blazor goes out of sync in some cases. The AutoComplete issue is different indeed but we still need to fix it. As a workaround delete the TextBox and add a new one from the toolbox (or copy an existing one).
