SFExpander is not showing content some times in one click.

[Praveen]

HI Team,

I am working on SFExpander with SFListView. My scenario is to implement the SFExpander inside the SFListView for that I implemented code with ExtendedExpander also but the expander is not Opening the Content Fully. 

The user wants to click two times to open the content fully(some times only this issue occurs).

I took the screenshots and attaching to it with the sample also.

I tried to implement the below link code to perform Expander scrolling.

Hi Praveen, 

  

Thank you for contacting Syncfusion support. 

  

We checked the reported Issues 

  

Regarding issue “Expander is not opening content Fully” 

The reported occurs due to setting auto row height to expander content. So you have to set HeightRequest to label or set row height as like below code snippet. 

Code snippet: 

  

… 

<local:ExtendedExpander.Content>     

<pancake:PancakeView CornerRadius="0,0,20,20" BackgroundColor="Gray">                  

<Grid RowDefinitions="40,40,40,40,40" Padding="10" > 

<Label /> 

… 

  

  

Please refer to the following  documentation expander with  Xamarin.Forms.pancakeview: 

KB link: How to add rounded corners for Xamarin.Forms Expander (SfExpander) | Syncfusion KB 

  

Regarding issue “Expander Scrolling not working” 

  

You bind the IsExpanded property in two way binding mode with IsExpanded bool value , but there is no definition for binded IsExpanded in ViewModel class . You have to define the IsExpanded binding property 

as like below code snippet. 

  

Code snippet: 

private bool isExpanded; 

    public bool IsExpanded 

    { 

        get { return this.isExpanded; } 

        set 

        { 

            this.isExpanded = value; 

            this.RaisedOnPropertyChanged("IsExpanded"); 

        } 

    } 

Please refer to the following documentation to bring entire expander when loaded in the listview.
