  Hi,
  We have a need to show C1FlexGrid column using a textbox. for that we use DataTemplate. now we have a need to TextWrap the content and to AutoSizeRows to show all the data.
  When using this scenario - AutoSizeRows DOES NOT WORK...
  
  Attached is a sample with 2 FlexGrids:
  1. Using our DataTemplate of Textbox - does not work.
  2. Not using a DataTemplate - works fine.
  
  Please advice.C1FlexGridWrapIssue.zip

  Hi,
  
  Thanks for the sample.
  
  If you are adding a TextBox in Celltemplate with IsReadOnly="True". Then we suggests you to use TextBlock instead. Then Resize the rows of flexgrid when it loaded in the view.
  

  
  <c1:Column.CellTemplate>
    <DataTemplate>
      <TextBlock Text="{Binding First, Mode=OneWay}" Background="Transparent" TextWrapping="Wrap" />
    </DataTemplate>
  </c1:Column.CellTemplate>
  

  
  
  Please refer the attached modified sample for the same : C1FlexGridWrap_Mod.zip
  
  Best Regards,
  Nitin

  Hi Nitin,
  
  while it does work when using a TexBlock we still need to use a readonly TextBox.
  
  using a TextBox in Celltemplate with IsReadOnly="True" allows for text selection and copying (partial or full) - and that is required (it why we use it)...
  
  How can we still get it to work with a TexBox?

  Hello Guy,
  
  We understood your scenario. But having TextBox in CellTemplate creating auto row size issue. So, that we have escalated this to the development team. We will get back to you once we have any update from them.[Internal tracking Id - C1XAML-29903]

  Hello Guy,
  
  It seems like you are using C1 4.0 version controls. Can you consider upgrading to 4.6.2?
  We only fix critical issues in .Net 4.0
