- When the layout is loaded the values are changed to 1, 2, and 3.

Release R2 2019 SP1 (LIB 2019.2.527)

ChildRowHeight can be set on the main table element of the control like this:

this.radGridView1.TableElement.ChildRowHeight = 750;

When the grid is in a hierarchy and a parent row is expanded, the inner child template will create a new table element and its ChildRowHeight is 205 which is the default value. It would be expected that the height of the inner table element is initially set as the height of the main table element of the control.

A possible workaround is to handle the ChildViewExpanded event of the grid this way:

private void RadGridView1_ChildViewExpanded(object sender, Telerik.WinControls.UI.ChildViewExpandedEventArgs e)
{
    GridTableElement tableElement = this.radGridView1.CurrentView as GridTableElement;
    if (tableElement != null && e.ParentRow.HierarchyLevel == 1)
    {
        tableElement.ChildRowHeight = 750;
        tableElement.InvalidateMeasure(true);
    }
}

Release R3 2019 (LIB 2019.2.729)

https://docs.telerik.com/devtools/winforms/controls/gridview/filtering/setting-filters-programmatically-(composite-descriptors)

When creating a composite filter descriptor with a value that contains an array of enums, it generates an expression with IN, and an exception is thrown when adding it to the FilterDescriptors on a RadGridView control.

 

Exception Message:

{"The expression contains undefined function call In()."}

 

The expression value is: ([RandomPropertyName] IN (1,3,9) OR [RandomPropertyName] = 10)

 

We have recently upgraded from 2015.2.728.40 (where this worked) to the Feb. 2019 version, then today upgraded to the May 2019 version. The issue remains.

 

The project includes the following Telerik references:

Telerik.WinControls.RadMarkupEditor
