textbox values cleared when clicked on Rowdetail

[Vinay]

Hi,
I am facing a weird issue in GridView.
When i input some value to textbox or any control inside a GridViewColumn.CellTemplate and the click on togglebutton or scrollbar of the grid. The value inside the textbox is cleared automatically.

Below is my code,

<telerik:RadGridView x:Name="dgIncidentTrackingReportSection" Visibility="Collapsed" IsFilteringAllowed="False" AutoGenerateColumns="False" BorderThickness="2" HorizontalAlignment="Stretch" CanUserReorderColumns="False" ShowGroupPanel="False" CanUserResizeColumns="False" CanUserDeleteRows="False" CanUserSelect="True" CanUserInsertRows="False" Margin="10,40,10,0" Grid.Row="4" RowIndicatorVisibility="Collapsed" Grid.ColumnSpan="2">
                        <telerik:RadGridView.Columns>
                            <telerik:GridViewToggleRowDetailsColumn />

                            <telerik:GridViewDataColumn Header="Rec. ID" IsReadOnly="True" DataMemberBinding="{Binding UserAccessID}" />
                            <telerik:GridViewDataColumn Header="Patient Name" IsReadOnly="True" DataMemberBinding="{Binding PatientName}" />
                            <telerik:GridViewDataColumn Header="MR #" IsReadOnly="True" DataMemberBinding="{Binding MedRecNumber}" />
                            <telerik:GridViewDataColumn Header="Account #" IsReadOnly="True" DataMemberBinding="{Binding AccountNumber}" />
