OnControlAddin Issue

[Martin]

hello guys,

i'm testing this control for developing a gantt for ms dynamics nav. Everything works fine but now i'm searching for a way to manually update the whole view, because i load data async nothing is shown in my gantt when it's loaded on my page. I want the control to completely update it's view when dataload is finished and i don't know which function to use or how to do this.

 

As u can see in pic1 page is open no data is shown.

As u can see in pic2 i only resize width a little bit, ganttPart is updated.

As u can see in pic3 i resize width an height more, gridPart is also updated.

i need a function to do the update, when my dataset i loaded.

Hi Martin,

The issue might lie as the RadGanttView.TasksSource is not notified when the data is loaded.
I suggest binding the RadGanttView.TasksSource to a collection that notifies when it is populated.

I've prepared a sample project demonstrating this approach. Take a look at the Tasks property in the ViewModel class. Whenever it is being set to a new collection it notifies for change.
I've added a button - "Populate tasks" that sets the ViewModel.Tasks to a new ObservableCollection<IGanttTask> and bind the TasksSource to Tasks:

<telerik:RadGanttView Grid.Row="1" TasksSource="{Binding Tasks}" VisibleRange="{Binding VisibleRange}" x:Name="gantt">
...
</telerik:RadGanttView>

Hopefully this helps.
