Add similar like DateColumn.DateTimeMode property for GridViewDateTimeColumn. Link in MSDN: http://msdn.microsoft.com/en-us/library/system.data.datacolumn.datetimemode.aspx

Description: Just use the button x times to show an additional form with a RadGridView Control on it. RadGridView is not releasing the complete allocated memory. JustTrace shows an increasing number of Telerik.WinControls.RadPropertyValue instances. 

Resolution: Not a memory leak. When a form is shown with the ShowDialog method, it should be explicitly disposed. If the form was shown using the Show method, the Dispose method does not need to be called explicitly. It will be called automatically when the form is closed.

Run the attached project on a monitor with 100% DPI scaling and open the Excel-like filter popup:

100%:

After moving the form to the second monitor with 150% DPI scaling, the filter popup is not OK:

150%:

The popup is smaller and smaller with each next opening (see the attached gif file) at 150%. If you decide to move back the form on the monitor with 100% DPI scaling, the filter popup is not scaled properly.

When selecting the child templates from the tree view in the left pane, the preview should be updated to show the child template.

To reproduce:

1.Add a grid and populate it with data.
2.Apply a theme to the entire application, e.g. TelerikMetro
3.Activate the grid editor.
4.Change the theme to VisualStudio2012Dark or HigthContrastBlack.
5.Activate the grid editor again. You will notice that editor's back color remains white and you are not able to read the text.

Note: if you apply initially VisualStudio2012Dark theme, editor's back color is correct. Please refer to the attached gif file, illustrating this incorrect style.

Workaround:

private void radGridView1_CellEditorInitialized(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)
{
    BaseGridEditor gridEditor = e.ActiveEditor as BaseGridEditor;
    if (gridEditor != null)
    {
        RadTextBoxElement el = gridEditor.OwnerElement.FindDescendant<RadTextBoxElement>();
        if (el != null)
        {
            if (ThemeResolutionService.ApplicationThemeName == "VisualStudio2012Dark")
            {
                el.BackColor = Color.Black;
            }
        }
    }
}

Print support for RadGridView.

ADD. RadGridView - add ability to move the column with the expanders to different position then the first one

Resolution: 
Set the SelfReferenceExpanderColumn property of the MasterTemplate to the preferred column. Here is the code snippet: 
radGridView1.MasterTemplate.SelfReferenceExpanderColumn = this.radGridView1.MasterTemplate.Columns[4];

If you refresh an object set property of entity context, the RadGridView is not updated. 

The sample code below does not work:

this.radGridView1.DataSource = entities.Countries;

int maxId = (from c in entities.Countries
                         orderby c.Id descending
                         select c.Id).First();

            Country country = new Country();
            country.Id = maxId + 1;
            country.Name = Path.GetRandomFileName();
            entities.Countries.AddObject(country);
            entities.SaveChanges(System.Data.Objects.SaveOptions.AcceptAllChangesAfterSave);

            entities.Refresh(System.Data.Objects.RefreshMode.StoreWins, entities.Countries);

Scrolling with the mouse wheel and the keyboard could be improved in some scenarios.

Add Page format functionality (like header, footer, page number) when you export a RadGridView to pdf similar to RadPrintDocument.
http://www.telerik.com/help/winforms/tpf-printing-support-radprintdocument-header-and-footer.html

To reproduce:
- Add a grid to a PageView and add the pageView to a dock window at run time.
- The grid should not be visible.
- Set your DPI setting to 150%

Workaround:
class MyViewDefinition : TableViewDefinition
{
    public override IRowView CreateViewUIElement(GridViewInfo viewInfo)
    {
        return new MyTableElement();
    }
}
class MyTableElement : GridTableElement
{
    public override void DpiScaleChanged(SizeF scaleFactor)
    {
        if (this.ViewTemplate != null)
        {
            base.DpiScaleChanged(scaleFactor);
        }

    }
    protected override Type ThemeEffectiveType
    {
        get { return typeof(GridTableElement); }
    }
}

//use the above definition like this:

 radGridView1.ViewDefinition = new MyViewDefinition();

To reproduce:
Add radGridView to a form
open the property builder
add GridViewCommandColumn
go to advanced settings
click the ellipse button of the Header Image property

Steps to reproduce:

1. Click column header to sort.
2. Click button which to export to Excel.
3. The rows return to unsorted.
4. Scroll down slightly and scroll back up and the sort is restored.

This happens after calling RunExport.

I attached a gif and a sample project.

If SqlDataReader object has been used for loading data in RadGridView, column expressions does not work.

GridTimeColumn will display and allow user to edit with TimeEditor Time and Time-Span column types from the Database.

Currently there is no way to sort group rows in RadGridView.

It appears that this scenario is not handled properly in our exporter. Consider the case where you have two templates that use view definition. 

The view definition from the second template is not exported at all.

Workaround: use the API of RadGridView to delete the row
