  There was a very similar issue to this logged here.
  
  And here is a simple project showing the problem.  Notice that when you attempt to enter a <space> in either of the TextBox controls, the first keypress seems to be ignored.  Subsequent <space> characters are ok.
  
  

  <UserControl    x:Class="SilverlightApplication61.MainPage"

          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

          xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

  >

   

  <UserControl.Resources>

     <DataTemplate x:Key="LabelTemplate">

        <TextBlock Text="{Binding ., StringFormat='\{0\}:'}" VerticalAlignment="Center" Foreground="Green" FontSize="12" Margin="25,0,5,0" />

     </DataTemplate>

  </UserControl.Resources>

           

  <Grid x:Name="LayoutRoot" Background="White">

   

     <telerik:RadDropDownButton Height="50" Width="50" DropDownWidth="280">

   

        <telerik:RadDropDownButton.DropDownContent>

   

           <Grid>

                       

              <Grid.RowDefinitions>

                 <RowDefinition Height="Auto" />

                 <RowDefinition Height="Auto" />

              </Grid.RowDefinitions>

                       

              <Grid.ColumnDefinitions>

                 <ColumnDefinition Width="Auto" />

                 <ColumnDefinition Width="1*" />

              </Grid.ColumnDefinitions>

   

              <telerik:Label Grid.Row="0" Grid.Column="0" Content="Field 1" ContentTemplate="{StaticResource LabelTemplate}" />

              <TextBox Grid.Row="0" Grid.Column="1" FontSize="14" Text="{Binding Field1, Mode=TwoWay}" Margin="0,4,3,2" />

   

              <telerik:Label Grid.Row="1" Grid.Column="0" Content="Field 2" ContentTemplate="{StaticResource LabelTemplate}" />

              <TextBox Grid.Row="1" Grid.Column="1" FontSize="14" Text="{Binding Field2, Mode=TwoWay}" Margin="0,4,3,2" />

                   

           </Grid>

               

        </telerik:RadDropDownButton.DropDownContent>

   

     </telerik:RadDropDownButton>

      

  </Grid>

       

  </UserControl>

  Hi there,
  I use the following workaround for this problem
  
  private void TextBox_KeyDown(object sender, KeyEventArgs e)
          {
              switch (e.Key)
              {
                  case System.Windows.Input.Key.Space:
                      AddCharachterToTextBox((TextBox)e.OriginalSource, " " );
                      e.Handled = true;
                      break;
                  case System.Windows.Input.Key.Enter:
                      AddCharachterToTextBox((TextBox)e.OriginalSource, "\n");
                      e.Handled = true;
                      break;
              }
          }
          
          void AddCharachterToTextBox(TextBox textBox, string newChar)
          {
              int position = textBox.SelectionStart;
              textBox.Focus();
              textBox.Text = textBox.Text.Insert(textBox.SelectionStart, newChar);
              textBox.SelectionStart = position + newChar.Length;
          }
  
  HTH,
  Juliana
