This Issue was already created on Telerik UWP Controls GitHub.

TargetParameterCountException when binding ItemsSource with x:Bind expression

I've check that this Issue being fixed using Binding instead of x:Bind but all templates are implementing x:Bind in all different frameworks. A temporary work arround could be use Binding on DataGrid page template.

[mvegaca]

Telerik team will apply a fix for this issue in the next few days in order to prevent the designer from crushing when x:Bind is used.

[crutkas]

We'll change from x:bind to binding as a quick work around now. comment the template why this is like it is. Keep this bug open and wait for the update to Telerik to change.

Looks like Telerik have a fix for this. asking for ETA for new nuget update from them

[crutkas]

they said next few days

[ralarcon]

Well, once available, we'll rollback the workaround.

[crutkas]
