If you are zooming a page containing a DateTimePicker with "AdaptiveMode" set to "AdaptiveMode.Auto", the application crashes occasionally with the error:
Microsoft.JSInterop.JSException: Cannot read properties of null (reading 'addEventListener') TypeError: Cannot read properties of null (reading 'addEventListener')
The more adaptive DateTimePicker instances the page contains, the more likely the error is to occur.
I seem to have a similar problem and not sure if it is related or not, so I'm putting a comment here. Let me know if this should be its own item. In my case, this issue will occur when I resize the window too quickly. It looks like the error is originating from the following javascript function:
bindPickerEvents() {
this.pickerElement.addEventListener("keydown", this.onPopupKeyDown, !0)
pickerElement appears to be null under certain circumstances.
It appears to happen when I have multiple DatePickers within components and the AdaptiveMode is set to Auto.
Is there any update regarding fixing this issue?
Any update on this? We also found that zooming is not the only way to trigger this exception – merely resizing the window can also cause this:
The dialog that can be seen includes a few `TelerikDateTimePicker` components. When shrinking and expanding the browser window again, the application crashes with the same error that occurs sometimes when zooming.
