Searchable combobox with large collection freezes application

[jernejp]

Hi,

I'm building an application where the user has to select our company's business partner. I get the partner list from an API call, but the collection where I save it is extremely large.

So when I have a searchable combobox where the user can search for the business partner, it sometimes freezes the application, because the list is so long.

Is it possible to make the combobox wait for the user to input the first  (or first few) letters, before actually searching? 

Thanks

Hi @jernejp 

Can you modify your combobox items as:

If(Len(TextInput1.Text) > 2,Filter(<<FIlter Query Arguments>>))

This will only filter if two or more characters are entered in the textInput control.

Hope this Helps!

Hi @yashag2255 

So if I understand correctly, I'd then have a text input and a combo box, and would use the text input to filter the combo box?

Can it all be done within the combobox? So that the combobox is empty untill user writes 2 characters, then the filtering query is executed?

Thanks

In that case, please try to modify your expression as:

If(Len(ComboBox1.SearchText) > 2,Filter(<Filter Query arguments>))

Hope this Helps!

Hi @yashag2255, thanks for your answer.

How would I add a StartsWith function here? So if in my PartnerList I have a number of comapnies, and the user inputs "pa", it would search for all partners that begin with PA?

For doing so, you can refer to below mentioned expression:

If(Len(ComboBox1.SearchText) > 2,Filter('PartnerList I',StartsWith(PartnerName, ComboBox1.SearchText)))

Here, PartnerList I refers to the name of DataSOurce and I am assuming PartnerName is the column that holds values for various partner name. Please replace the values in expression with actual attributes/control names.

Hope this Helps!
