If RadSlider is using for CellEditTemplate of RadGridView it's causes an exception:
 System.ArgumentNullException: Value cannot be null.
 Parameter name: dp
See the following code:
<Grid:RadGridView AutoGenerateColumns="False" AlternateRowBackground="LightGray" CanUserDeleteRows="False" CanUserInsertRows="False" ShowGroupPanel="False" DataLoadMode="Asynchronous" RowEditEnded="decisionGrid_RowEditEnded" AlternationCount="2" ColumnWidth="*">
   <Grid:RadGridView.Columns>
      <Grid:GridViewDataColumn IsReadOnly="True"  Background="Black" Width="80" Header="Well" />
      <Grid:GridViewDataColumn IsReadOnly="True" IsGroupable="False" Header="Current Choke" />
      <Grid:GridViewDataColumn IsReadOnly="True" IsGroupable="False" Header="Ideal Choke"  />
      <Grid:GridViewDataColumn IsReadOnly="False" IsGroupable="False" Header="New Choke" >                           
      <Grid:GridViewDataColumn.CellEditTemplate>
        <DataTemplate>
          <Controls:RadSlider  Maximum="100" Minimum="0" Value="{Binding NewChoke, Mode=TwoWay,UpdateSourceTrigger=Explicit}" />
        </DataTemplate>
      </Grid:GridViewDataColumn.CellEditTemplate>
      </Grid:GridViewDataColumn>
    </Grid:RadGridView.Columns>
</Grid:RadGridView>

Hello Vadim,

I've managed to reproduce the issue and the problem is already fixed. The fix will be publicly available with the next internal build.

P.S. I've added 1000 Telerik points to your account.

All the best,
