For example the control has 25 items, I can scroll only to the first 10-11, cannot see the rest of the items.

when applying Grouping and RowHeight to the DataGrid and expand the row details, the following happens -> The DataGrid in the RowDetails only appears for alternate rows. 

In addition the RowHeight does not apply to the Grouping Row.

Workaround:

Remove the RowHeight from the DataGrid and set the CellContentStyle property to the columns and set the TextMargin to the DataGridTextCellStyle, and ButtonMargin to the DataGridToggleRowDetailsCellStyle. Here is an example when setting them to 0:

            <telerik:DataGridTextCellStyle x:Key="cellStyle"
                                           TextMargin="0"/>


            <telerik:DataGridToggleRowDetailsCellStyle x:Key="toggleStyle"
                                                       ButtonMargin="0"/>


            <telerik:RadDataGrid.Columns>
                <telerik:DataGridToggleRowDetailsColumn CellContentStyle="{StaticResource toggleStyle}"
                                                        IsFrozen="True"/>
                
                <telerik:DataGridTextColumn PropertyName="Country"
                                            CellContentStyle="{StaticResource cellStyle}"
                                            IsFrozen="True" 
                                            CanUserReorder="False"  />

                                            CellContentStyle="{StaticResource cellStyle}" />

In a scenario with dynamic removing and adding of columns, there is a memory leak when clearing the columns by invoking the Clear() method of the columns collection.

A work-around is to remove the columns one by one:

    for (int i = this.dataGrid.Columns.Count - 1; i >= 0; i--)
    {
        this.dataGrid.Columns.RemoveAt(i);
    }

Dear Telerik-Team

with the new version 9.0.0 on Android the Scheduler doesn't display the Date/Timepicker on creating/editing an new appointment. The Date/Timepicker Popup is only displayed when the "EditAppointmentDialog" is closed. You can easy reproduce it. Just add the Scheduler to a plain project.

I have attached a VS solution where you can reproduce it.

Thanks for helping/fixing it as soon as possible. I need this new version becasue of another bugfix for scheduler in it...
