Custom search against large data source

[axl]

Hello,

I haven't found an explicit statement within the documentaion about this, so I'll just ask: is it possible to implement the search in such a way that one pass the users input (from a textbox) to a query service, which then returns the filtered values to show within autocompletes dropdown? Kind of like how one know it from web-applications and the search goes to the backend as an ajax call.

It seems to me that one can only pass ready lists to the automcomplete-controls datasource property. This is unattractive if the data source contains more than 15.000 entries or if several data sources are to be queried.

Concretisation: it is about Windowsforms under .Net5.

Thanks for any hints!

Hi Axel 

 

Thank you for contacting Syncfusion Support. 

 

From your requirement, we could understood that you want to apply your own custom search for Autocomplete control and with list of large data. However you can acheive it by bounding the data with Bindingsource control and you can implement custom search using “PopulateListWithMatches ” function in AutoComplete control. Please find the sample for the same from following link:
