Hi,

 I'm looking to use the RadGridView with a specfic use case for filtering.  We're in an MVVM setup, where filtering of the data rows is performed in the viewmodel rather than in the view.  However, I'd still like to use a filter row in this setup.  

Effectively, I want that filter row to be able to bind to our own FilterViewModel property in the view model that represents it.  Imagine this as just a TextBox for each column sitting in the filter row on top that is represented by a Dictionary<string,string> in the viewmodel: where the key is the column unique name, and the value is what the user entered for that textbox.  Behind the scenes, when this dictionary changes, we will perform the filtering ourselves.

As far as I understand it, this would require a custom filter control in the filter row of the RadGridView, and notification when the user changes a value in one of those filters.  However, it seems like it's impossible to use the filtering row or indicators of the RadGridView without using IFilterDescriptors or other Telerik-specific filtering items.  Is that true?  How could I make this scenario work?

 I'm able to do this to a certain extent with Infragistics controls -- we're evaluating Telerik to move over to and this is fairly critical to that process. 

 Thanks,

Alan

I want to change the width of the label part of DataFormDataField. The correct place to edit should be the controls ControlTemplate:

 I want this to be something like: 

The width should not be a fix value in the ControlTemplate. It should be variable so different DataForms can have different label widths. Is that possible?

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 

Jakub
