I have a panel class ExRadPanel, that inherits from RadPanel. I try to apply to it a copy of the style that is used for PropertyGridHelpElement in RadPropertyGrid. Below is my test code, but it doesn't work properly. Some style is attached to FillPrimitive inside ExRadPanel, but the visual effect is not like I expect.

Is that possible to make modify a theme in runtime to make a copy of the required style setting with proper settings?

private static void FixTheme(Theme theme)
{
    // try to add registration
    var sg = theme.FindStyleGroup(typeof(RadPropertyGrid).FullName);
    sg.Registrations.Add(new MyStyleRegistration
    {
        RegistrationType = "ElementTypeControlType",
        ElementType      = "Telerik.WinControls.RootRadElement",
        ControlType      = typeof(ExRadPanel).FullName
    });
    sg.Registrations.Add(new MyStyleRegistration
    {
        RegistrationType = "ElementTypeControlType",
        ElementType      = typeof(RadPanelElement).FullName,
        ControlType      = typeof(ExRadPanel).FullName
    });

    var copy = sg.PropertySettingGroups.ToArray();
    foreach (var settingGroup in copy)
    {
        if (settingGroup.Selector is null)
            continue;
        if (settingGroup.Selector.Value != nameof(PropertyGridHelpElement))
            continue;
        {
            // trying this ... 
            var newSg = new PropertySettingGroup
            {
                Selector = new ElementSelector(settingGroup.Selector.Type, nameof(RadPanelElement)),
                BasedOn  = settingGroup.BasedOn
            };
            newSg.Repositories.AddRange(settingGroup.Repositories);
            newSg.PropertySettings.AddRange(settingGroup.PropertySettings);
            sg.PropertySettingGroups.Add(newSg);
        }
        {
            // ... and this    
            var newIi = new PropertySettingGroup
            {
                Selector = new ElementSelector(ElementSelectorTypes.TypeSelector, typeof(FillPrimitive).FullName),
                BasedOn  = settingGroup.BasedOn
            };
            newIi.Repositories.AddRange(settingGroup.Repositories);
            newIi.PropertySettings.AddRange(settingGroup.PropertySettings);
            sg.PropertySettingGroups.Add(newIi);
        }
    }
}

UI automation doesn't work with Telerik grid, even after setting "EnableCodedUITests = true"

Hi,

We have problem identifying objects on Telerik grids, from UI automation tool. Quite many screens in our application are using Telerik grids. We now are trying UI automation using Ranorex. Most parts are going good, except Telerik grid! Basically, objects inside the grid are not identified as they should.

Found similar discussion at https://www.telerik.com/forums/635401-gridview and we made change as per suggestion, by introducing "EnableCodedUITests = true". However, no good lunch, it worked only partially.

For ex, from the screen below, would like to access value of 'Status' from first row.

Expectation would be, Row0/1(based on indexing logic), column 'Status' and text/value "Arrived". However, it doesn't work so! Ranorex thinks, its something to discuss with Telerik. They asked to test it using 'inspect.exe' tool from win10 sdk. We tried and got same result. Below is the screenshot of result form inspect.exe

Row number is OK, but not column name is identified.. also, Value/Text is empty.

If inspect.exe cannot detect, heard no other automation tool in market can!

By the way, it works well with win.net grids.

Here is the sample of inspection on win.net grid... Column name and cell values are identified very well.

How can this be fixed for Telerik grid?!

Thanks in advance,

Vijay
