Hi all,

 I am using the RadRichTextBox to display a docx file in ReadOnly mode. 

By default, the RadRichTextBox shows a gray background behind the page. I would like to change this from gray to black, but I cannot figure out how. I would rather not include a theme from telerik in my assembly as this is the only visual change I need to make.

Just to be clear, I want to change the background behind the page, not the color of the page itself.

Thanks

After looking at the CRM demo I decided to implement a similar type of functionality where based on a bool state the grid would show either a few columns or all columns

      <telerik:RadGridView helpers:GridViewColumnHelper.HideNonImportantColumns="{Binding IsInOverviewState}"
                             ItemsSource="{Binding Contacts}" ColumnWidth="*"

I am using Prism, everything works fine if I set a Minimum Height and Width of the main Shell and set the WindowState to normal. However, if I start the application maximized without these settings, when the grid is loaded, although it shows the right number of columns the width of the grid is incorrect (too big), if I slightly adjust the size of the window everything sorts itself out. 

 This is the grid definition 

 <Grid.ColumnDefinitions>

            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="2*"/>
            <ColumnDefinition Width="2*"/>
        </Grid.ColumnDefinitions>

 if you see the attached files you will see what I mean.

Thanks for any help in advance. 

I have a GridView that has 3 columns.  However, the host Grid needs to be just the width of the 1st column.  I have bound the column's Width Property to my Model View as shown:

However, the Cell should resize only based on the content size so it is defined as SizeToCells:

How can I set the grid width to match the width of the name column's width?  Is there a converter that takes the AutoSize value from the column and converts it to Pixels?  Or, can I set the System.Windows.GridLength = NameColumnWidth?  Can I do this another way if I don't use SizeToCells?

I have stumbled upon an issue where I only want the user to be able to edit the lower half of a matrix (It is a matrix that is symmetrical across the diagonal). I am creating a datatable based on a 2d array. 

 the grid is defined like this:

And then I have the following viewmodel:

NullvalueToBoolean is defined as follows:

And finally the codebehind:

 The code produces the following output when I try to edit one of the cells that are not readonly:
System.Windows.Data Error: 40 : BindingExpression path error: '0' property not found on 'object' ''DataRow' (HashCode=9659819)'. BindingExpression:Path=0; DataItem='DataRow' (HashCode=9659819); target element is 'TextBox' (Name=''); target property is 'Text' (type 'String')

However, if I remove the code that sets the ReadOnlyBinding, editing works fine. Do you have a suggestion on how to fix/avoid this issue? Maybe there is a better way to solve this problem with the Telerik UI for WPF?

i m trying reload my diagram. Saving is going well but if i m try load data from xml string shapes are loaded correctly but there are no connections between shapes. I m using ObservableGraphSourceBase<GraphNode,Link> as graph source and it inherit ISerializableGraphSource interface. During the debug i ve found out that method DeserializeLink is never call. Could you be so kind and give some advice how to figure it out.



Thank you very much.

Best regards

ps: here my serialization class

Hello,

this dialog should have a fixed size for the column width selector: as it doesn't have one, the width of the dialog changes when we change the size.

The same happens when we change the value in any of the up/down that are in the dialog.

This is not a very good user experience.

I have a an MVVM app where a page has a gridview bound to an entitiyframeworkdatasource.  The data loads as soon as the page loads and takes a while... so it blocks the UI thread.  Is there a way to prevent this?  I tried using another thread but couldn't get it to work right.

Also, how would I go about saving and undoing changes?  I created a button to save where I just call SaveChanges on the context.. and that works... But if I revert all changed entities in the context, the grid doesn't update the rows.

Are the 3d charting features depreciated?

The above link is all the documentation I can find for 3d charting features. 

Thanks
