Re-ordering Listview Items

[Lindsay Miles]

Hello,

Does the SFListView support drag n drop reordering in Xamarin forms?

Any sample code for that?

If not, is there any SF control that will?

thanks

[Dinesh Babu Yadav]

Hi Lindsay, 

 

Thank you for using Syncfusion Products. 

 

Currently, SfListView do not have support for “Item drag and drop” and we have already considered this as feature request. We have added it into our feature request list, and the feature will be available in our upcoming 2017 Volume 3 main release. 

 

However, SfDataGrid control provides support for “Row drag and drop” feature and you can enable row drag and drop functionality by setting AllowDraggingRow to “true”.

Please refer below UG link for further details.

Do you have any plan for sflistview "drag and drop" feature please? it is very nice on sfdatagrid but it is hard to do horizontal list using sfdatagrid

[Dinesh Babu Yadav]

Hi Emil, 

 

Yes, we have planned to include the reported feature “Support for Item drag and drop in SfListView” in our upcoming 2017 Volume 3 main release. We will let you know once the feature is implemented and included in release.

In the meantime you release the Drag and Drop support, is there a way I can implement it on my own, using your ListView control? I can't use the GridView, because I need each cell to be customized like a Card (I don't know if DataGrid supports that?).

I need to deliver a product, and if I can't add Drag and Drop to this, I will need to use regular ListView for Xamarin Forms :-(

Hi Joel, 

 

Currently, we don’t have any workaround for the reported feature “Item drag and drop” at our end. However, we have planned to include the reported feature “Support for Item drag and drop in SfListView” in our upcoming 2017 Volume 3 SP 1 release which is scheduled to be rolled by end of August month. We will let you know once the feature is implemented and included in release.

Hi Joel,

you can customize sfdatagrid as you want like listview. see the examples  provided by syncfusion. usually you need to use single column definition with whatever datatemplate you need. Only problem I found out that if your datatemplate is too complex, drag and drop isnt very useful, user will have hard time to drag and drop it.

Hi Joel, 

 

Using GridTemplateColumn, you can create your own view by creating the CellTemplate or CellTemplateSelector. GridTemplateColumn column was extend from GridColumn. Please refer the below UG link  

to more details about GridTemplateColumn column.

Hi, I just saw you released volume 3. Has Drag and Drop support been added for ListView?

[Dinesh Babu Yadav]

Hi Joel,  

 

We are implementing the reported feature “Support for Drag and Drop in SfListView” at our end, but we are facing some Xamarin framework hurdles. So, we are unable to complete and include the feature in the 2017 Volume 3 main release. We will assure you that it will be included in our upcoming 2017 Volume 4 main release and we will let you know once the feature has been completed and we will appreciate your patience until then.

Is SFDataGrid capable of handling all features of list view? Primarily looking for CacheMode - Recycle and Retain. I understand DataGrid doesnt allow Recycle? Is that correct?

[Divakar Subramaniam]

Hi Prasad, 

 

By recycling and retaining, if you mean Data Virtualization here (i.e., reusing rows and columns without creating new rows or columns), then SfDataGrid allows it.
