[Solved] Bug RadGridView Q3 2010 IsReadOnly property not working

[Yvan]

Hi telerik,
I have a grid that can be in edit mode or not depending on user rights. Each column contains a section CellTemplate and CellEditTemplate. I tried unsuccessfully to affect the properties of IsReadOnly and IsReadOnlyBinding of the definition section of the grid. The grid is unfortunately still in edit mode. I did some research on your forum and I found that I'm not the only one having this problem (see http://www.telerik.com/community/forums/silverlight/gridview/please-please-don-t-change-isreadonlybinding-as-it-is-in-latest-internal-build.aspx ). Question, why the radgrid have two properties for the same purpose (IsReadOnly and IsReadOnlyBinding) ?

Here a sample:

<telerik:RadGridView ItemsSource="{Binding ItemsSource}"
              AutoGenerateColumns="False"
              CanUserInsertRows="{Binding CanUserInsertRow}"
              ShowInsertRow="{Binding CanUserInsertRow}"
              IsReadOnly="{Binding IsGridInReadOnlyMode}"
              IsReadOnlyBinding="{Binding IsGridInReadOnlyMode}">
  <telerik:RadGridView.Columns>
     <telerik:GridViewDataColumn DataMemberBinding="{Binding CompanyName}"
                        Header="Company Name" >
        <telerik:GridViewDataColumn.CellTemplate>
           <DataTemplate>
              <TextBlock Text="{Binding CompanyName}" />
           </DataTemplate>
        </telerik:GridViewDataColumn.CellTemplate>
        <telerik:GridViewDataColumn.CellEditTemplate>
           <DataTemplate>
              <TextBox Text="{Binding CompanyName}" />
           </DataTemplate>
        </telerik:GridViewDataColumn.CellEditTemplate>
   </telerik:GridViewDataColumn>

 

Thanks for reply

Hello Yvan,

The reported behavior is not a bug since the logic behind is created in such a way that the editing is allowed if a CellEditTemplate is defined. However, we do make some additional considerations on the topic and we reach to the conclusion that it is more expected to be the other way around - once the read-only properties are set to true, editing is not allow. 
Considering the existence of the two properties, although they seem the same and have similar functionality, the idea behind each of them is a bit different. The IsReadOnly property is used for setting the whole grid or a particular column as read only. On the other hand, you may work with IsReadOnlyBinding property when you aim at controlling the editing of a particular cell for example. You may take a look at our online documentation for further reference.

Does this mean this will be changed in the future? Meanwhile what is the recommended workaround for this scenario?

edit: I'm doing the same, but am using the IsReadOnlyBinding on the column....
