Asked On March 3, 2017 01:46 PM UTC

Hello, i have populated sfautocomplete with 100 items under android with xamarin forms. When i scroll down in suggestionlist and select some item the wrong
item is displayed in the autocompeletebox. It always takes a previous item from the suggestionlist. How can i fix this issue?

Hi Richard,

Thank you for contacting Syncfusion Support.

We were unable to reproduce the reported issue “Wrong item get displayed from SuggestionList in AutoComplete”. We have created a sample for your reference please download the same from below link.

Please run the sample and check whether the issue still persists at your end. If not, please apply your changes and revert the modified sample with the following detail Syncfusion assembly version which you are using? This would help us to work inline with your requirement.

Hello, i am using the datasource with displaymember and valuepath. The sample seems to be ok, but it uses autocompeletesource with a simple list of strings.
Please can you check this with a list of datasource objects. As suggest it would be also very useful to preselect a item from list through valuepath. This is not
possible, because selectedvaluepath has only a getter.
Greetings Richard

Thank you for the sample and i figured out where the bug is :

Use this code to fill the collection in your created sample.

for (int i = 0; i < 100; i++)
{
    if (i == 10 | i == 20 | i == 30 | i == 50 | i == 90)
    {
       //twice --- 
personCollection.Add(new Person("Item " + i.ToString(), i.ToString()));     }     personCollection.Add(new Person("Item " + i.ToString(), i.ToString())); }
The Problem is that twice entrys with same Text are not shown and so all selected items after index 10 are not correct.

Issue 2:

Textsize and Dropdowntextsize are not working correctly. Fontsize on Emulator and Device doesn't match! Very big difference.

Issue 3:

Predefined Watermark 'Enter Text' not removeable until watermark is set to ' '!

Issue 4:

Clearing text or selection dosen't clear previous selected index and value !
Set Selectedindex to value -1 is not possible and can not be used to clear previous selection.

Issue 5:

Displayed text after selection from suggestionlist is editable but entry is not validated and it doesn't match to the list entrys after leaving control.

Issue 6:

No possibility to preselect a existing item in list. It is not possible to set a value to selectedvalue.


Thank you and greetings ...

Hello, just use the attached sample. Just Click on the box scroll down and select for example item 56. What result you get on screen? Definitly not item 56.
The problem is that entrys with a same text (displaymember) are shown only once in list and so the result after this entrys will be not correct.
This is a sample but in real there is the possibility that you can have more entrys with same text but with different values.
I also detected when the datasource is not set and you click on the autocompletebox (ShowSuggestionsOnFocus="True") a fatal exception occurs.

Greetings Richard
