Flicker can be observed when datagrid is manipulated/updated, or entering in edit mode. One example is tapping on a column header - when there is a column with a HeadetTemplate, the column header flickers. Other example is to double-tap a cell to go in edit mode. Also the behavior can be reproduced when DataGrid TemplateColumn is used.

Currently, all groups are expanded by default. We should expose methods to collapse/expand certain groups. Furthermore, CollapseAll, ExpandAll groups should be considered as well.

I have an custom column extending "DataGridTextColumn". This column overrides "CreateGroupDescriptor" methods and returns an instance of "DelegateGroupDescriptor". Once we group items in this column it can never be cleared/un-grouped.

 

Any help would be heighly appreciated. Thanks in advance.

Currently you can bind to SelectedItem but not the entire collection of SelectedItems. Being able to access the collection would greatly simplify programmatic selection and deselection of items in the DataGrid, especially with an MVVM project structure.

 When defining a Date column like

<tdg:DataGridDateColumn PropertyName="ExpiryDate" HeaderText="Expiry"/>


and binding data with a type with Nullable datetime

public System.DateTime? ExpiryDate
{
   get { return _expiryDate; }
   set { SetProperty(ref _expiryDate, value); }
} 

We get an exception

 

Is there a workaround?

 

Thanks

SizeMode="Fill" for Xamarin.Forms datagrid column to fill the space left

e.g.

<radDataGrid:DataGridDateColumn PropertyName="Date" SizeMode="Fixed" Width="80" />
<radDataGrid:DataGridTextColumn PropertyName="Title" SizeMode="Fill"  />
<radDataGrid:DataGridNumericalColumn PropertyName="Score" SizeMode="Auto" />

=>

First column has width 80, 3rd column has width of content (already working)

NEW: Second column occupies the space left

Datagrid

 

Built in features for:

- Paging

        eg. https://demos.telerik.com/aspnet-mvc/grid/paging

- Search Panel

        eg. https://demos.devexpress.com/MVCxGridViewDemos/Filtering/SearchPanel

​- Sorting

        eg. https://demos.telerik.com/aspnet-mvc/grid/sorting

 

I am trying to replicate a part of our MVC application using xamarin.forms.
The forms  required will have a datagrid, when a row is clicked I want to open a pdfViewer.

These built in features would help me and others.

 

Regards,

Graham
