sfCombobox not all elements are displayed

[David]

Good afternoon,

The sfCombobox does not show all the elements and in some cases the scroll does not work, it only works when the list is very large, but when it only exceeds by 1 or 2 elements these are not shown and the scroll does not work.

Version 18.2.0.56

Hi David,

Greetings form Syncfusion.

We have analyzed your query and the default value of MaximumDropDownHeight is 400, so that when items are above height, dropdown items are scrolled. We suggest to use MaximumDropDownHeight property of SfComboBox to resolve the reported issue as below code snippets. 

XAML:

 

<combobox:SfComboBox x:Name="comboBox" Grid.Column="1" Grid.Row="1" MaximumDropDownHeight="200" SuggestionBoxPlacement="Top" HeightRequest="40" Watermark="Select name"  DataSource="{Binding EmployeeCollection}" MultiSelectMode="None" DisplayMemberPath="Name"  /> 

 

We have created sample based on this please find the sample from below.

Sample:

We suggest you to try our sample and if you are still facing same issue, please update following details ? 

1.      Update modified sample with reported issue 

2.      Update replication steps to reproduce the issue 

It will help us to provide better solution at the earliest.
