Columns are generated using data binding / templates e.g.
<telerik:GridViewDataColumn DataMemberBinding="{Binding Path=Isin}" HeaderTextAlignment="Center" Header="ISIN"/>

also
<telerik:GridViewCheckBoxColumn ...

and some other like that

<telerik:GridViewDataColumn Header="" HeaderTextAlignment="Center" IsGroupable="False" IsFilterable="False" SortMemberPath="">
   <telerik:GridViewDataColumn.HeaderCellStyle>
        <Style TargetType="telerik:GridViewHeaderCell">
            <Setter Property="ContentTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <StackPanel>
                            <TextBlock Text="" HorizontalAlignment="Center"/>
                        </StackPanel>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
        </Style>
   </telerik:GridViewDataColumn.HeaderCellStyle>
   <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
        </DataTemplate>
   </telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

This is mine RadGridView

<telerik:RadGridView Grid.ColumnSpan="4" Grid.Row="5" DataLoadMode="Asynchronous"
                            ScrollMode="Deferred" AutoGenerateColumns="False"
                          SelectedItem="{Binding NewIssueItemSelected, Mode=TwoWay}" ShowGroupPanel="False" IsFilteringAllowed="False"
                          ItemsSource="{Binding Path=....}" IsReadOnly="True" MinWidth="1100" Height="720" FontSize="10"
                          Grid.RowSpan="2">

Hi Alberto,

Unfortunately from provided info so far I cannot tell you what is going on and why you see such issue and my suggestion is to isolate the case in small project (where the problem can be reproduced) and send us this project via support ticket. We will review your scenario and we will let you know about our findings.

Sincerely yours,
Vlad

Hello Alberto,

I've checked your project and indeed your right. We fixed this immediately and the fix will be part of our upcoming latest build (this Friday). In the meantime please use Header property of the columns instead HeaderCellStyle. Here is an example:

<telerik:GridViewDataColumn HeaderTextAlignment="Center" IsGroupable="False" IsFilterable="False" SortMemberPath="">

<telerik:GridViewDataColumn.Header>

<StackPanel>

<TextBlock Text="Some text" HorizontalAlignment="Center"/>

<TextBox Width="200"/>

</StackPanel>

</telerik:GridViewDataColumn.Header>

<telerik:GridViewDataColumn.CellTemplate>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

Best wishes,
Vlad

Well that is another issue, using <telerik:GridViewDataColumn.Header> will affect the way databinding works, when the object you want to bind is outside of the itemsource you should be using elementname and that works really well under <telerik:GridViewDataColumn.HeaderCellStyle> but is broken <telerik:GridViewDataColumn.Header>

e.g.
<telerik:GridViewDataColumn.HeaderCellStyle>
                            <Style TargetType="telerik:GridViewHeaderCell">
                                <Setter Property="ContentTemplate">
                                    <Setter.Value>
                                        <DataTemplate>
                                            <StackPanel>
                                                <TextBlock Text="Issue Name" HorizontalAlignment="Center"/>
                                                <sdk:AutoCompleteBox Grid.Column="2" TabIndex="2" Height="20" Width="295" AllowDrop="False" IsDropDownOpen="False"
                                                                ItemsSource="{Binding ElementName=LayoutRoot, Path=DataContext.Collection}" FilterMode="Contains"
                                                                ValueMemberPath="IssueName" Text="{Binding item, Mode=TwoWay}" MinimumPrefixLength="2">
                                                    <sdk:AutoCompleteBox.ItemTemplate>
                                                        <DataTemplate>
                                                            <StackPanel Orientation="Horizontal">
                                                                <TextBlock Text="Issue : " FontWeight="Bold" />
                                                                <TextBlock Text="{Binding ...}"/>
                                                                <Rectangle Style="{StaticResource DividerStyle}"/>
                                                                <TextBlock Text="{Binding ...}" FontWeight="Bold" />
                                                            </StackPanel>
                                                        </DataTemplate>
                                                    </sdk:AutoCompleteBox.ItemTemplate>
                                                </sdk:AutoCompleteBox>
                                            </StackPanel>
                                        </DataTemplate>
                                    </Setter.Value>
                                </Setter>
                            </Style>
