How to have autocomplete height grow as items are selected

[Minh Tran]

Hi, at the moment I have a grid. Inside this grid is a scrollview, followed by another grid. Inside this Grid, it has 2 columns and many rows. The issue I'm currently having is that the autocomplete doesn't grow in size as more tokens are added. They just get hidden. 

Any tips or suggestions would be greatly appreciated.

Hi Minh,



Greetings from Syncfusion.



In our SfAutoComplete, when selecting multiple item during Token mode, the items will get scrolled inside the SfAutoComplete text box. The size of the control will not change.



Please check by scrolling inside the SfAutoComplete TextBox and let us know if you have any clarification on this.

Hi there,

a scroll in the box is no longer present. The grid that host the data is within a scrollview. Is there a way to get the size to automatically change?

Hi Minh, 

 

Sorry for the inconvenience. 

 

We do not have have direct support to change the size of SfAutoComplete. We can use the below given workaournd on SelectionChanged event of SfAutoComplete, during the selection change we have changed the height of SfAutoComplete. 

var autocomplete = (sender as Syncfusion.SfAutoComplete.XForms.SfAutoComplete);
            if (autocomplete.SelectedItem != null && autocomplete.SelectedItem is IList)
            {
                var count = (autocomplete.SelectedItem as IList).Count;
                var extendheight = Math.Ceiling(count / 2d) * 45;
                if (extendheight != 0 && autocomplete.HeightRequest != extendheight)
                {
                    autocomplete.HeightRequest = extendheight;
                }
                else if (extendheight == 0 && autocomplete.HeightRequest != extendheight)
                {
                    autocomplete.HeightRequest = 45;
                }
            }
