[Solved] When row and column virtualization is true, data bindings not maintained on DetailsVisibilityProperty

[J]

I have a RadGridView whose DetailsVisibility is bound to the IsChecked value of a ToggleButton.

private void Init()
{
    var toggleBinding = new Binding("IsChecked") {
        Source = this.toggleButton,
        Mode = BindingMode.TwoWay,
        Converter = new BooleanToVisibilityConverter()
    };

    this.parentRow.SetBinding(GridViewRow.DetailsVisibilityProperty, toggleBinding);
}

Where this.toggleButton is of type Primitives.ToggleButton and this.parentRow is of type Telerik. ... .GridViewRow. The RadGridView is horizontally scrollable and when I check the ToggleButton, making the details visible, then scroll such that the ToggleButton is not viewable, the row details automatically collapses. The cell values maintain their binding when I scroll such that the cells do not clear when I scroll away and scroll back, but the toggle button does not. This is obviously an issue because I do not want the row details to collapse when scrolling.

Is there a workaround or can this be addressed? Thanks.

Hello J,

We have a special column called GridViewToggleRowDetailsColumn which will maintain state even with virtualization turned on. If you decide to use a custom approach for this then I am afraid that it would be up to you to maintain that state.
