Hi syed,

Hi Syed, 

 

Thanks for your patience, 

 

Based on your shared information, we suspect that you want to load the popup suggestion based on searched character (more than or equal to length 3). So, we suggest you use our MinLength property to achieve your requirement. if you did not want to use the MinLength property then you can also achieve this custom filtering behavior using our filter event.  

 

To know more about our custom filtering action and SuggestionCount. please refer the below documentation link. 

 

Documentation link for custom filtering: https://blazor.syncfusion.com/documentation/autocomplete/filtering/#custom-filtering
