Gruop Collapse issue

[James]

Hi, I create 5 group and each group has  more than 1 item , Some group disappear when collapse groups.
i,e:

ExpandAll looks like :

Group1

     Item1_1
     Item1_2

Group2

     Item2_1
     Item2_2

Group3

     Item3_1
     Item3_2

Group4

     Item4_1
     Item4_2

Collapse group looks like :

Group1
Group2
Group4

It's easy to reproduce i guess

Hi James,  

  

Thanks for contacting Syncfusion support.  

  

We have checked the reported issue “Collapse all is not working” from our end. We have prepared the sample based on the information given by you. In our sample we have loaded the listview with groups and collapse all the groups in the button click. Unfortunately, the reported issue does not replicate at our end and the listview is loaded in the view as expected.  

  

For your reference we have attached the sample and you can download it from the below link.  

  

Sample: http://www.syncfusion.com/downloads/support/forum/139181/ze/Sample1435373129   

  

Can you please check whether the reported issue occurs in our sample also? If possible, can you please modify the sample to replicate the reported issue in our sample which would highly help us to analyze the query better and provide an appropriate solution.

Thanks your support,

After testing, I founded that this issue cause when set  "SfListView.LayoutManager GridLayout SpanCount="2""

i.e:

.....>

</listView:SfListView.GroupHeaderTemplate>

<listView:SfListView.LayoutManager>

     <listView:GridLayout SpanCount="2" />

</listView:SfListView.LayoutManager>

<listView:SfListView.ItemTemplate>

<....
