I am trying to use Maui Combo box control one my screen but faced some strange issue.

After some interactions either by clicking the combo or by typing keyword the cursor started blinking so fast and due to this whole screen got stuck. I had to restart the application.

Please see the attached video for your reference.

Any help would be appreciated.

Hello Bikash,

Thank you for the provided video.

As I do not have the source code to analyze the issue further, I can only speculate that the behavior of the combobox comes from a hard coded width and height request. Not having enough space for the text to be visualized might cause the clear button and the selection in the box to glitch. If you could take the time to create a sample app where the issue is reproduced I might investigate the matter further and offer an optimal solution.

I look forward to you reply.

Hello Bikash,

Thank you for the provided sample project.

I took a look into the sample and after careful testing I noticed that the issue comes from the IsEditable property. This occurs because the entry of the ComboBox steals the focus. That said, I have logged a bug on your behalf and updated your points for finding it. You can follow the item on our public feedback portal to be notified of its status: 

https://feedback.telerik.com/maui/1570173-combobox-winui-entry-steals-focus-and-cannot-close-the-dropdown-in-edit-mode 

In regards to a workaround, I am afraid I cannot offer such. The issue can only be seen when the ComboBox is in Editable mode. The only way to go around that is if you set IsEditable to "false".

Let me know if you have any additional questions.

Regards,
Antoan
