Hi,

   I have created a class Employee with Properties FirstName,LastName,Title, and Date of Birth. By default  I kept Browsable attribute value 'false' for FirstName Property. In the set block of Title and Date of birth I am trying to change the value of Browsable attribute value of firstName Property to true and false respectively. 

     It is changing the value to true and showing the FirstName Property while loading the grid.After that again if I edit DataOfBirth it is not hiding the property 'FirstName' even when i set browsable attribute value false.

I am using following code to modify the browsable attribute value:

   public void ModifyBrowsableAttributeOfProperty(string prop, bool value)
        {
            PropertyDescriptor descriptor = TypeDescriptor.GetProperties(this.GetType())[prop];

            BrowsableAttribute attribute = (BrowsableAttribute)descriptor.Attributes[typeof(BrowsableAttribute)];


            FieldInfo field_info = attribute.GetType().GetField("Browsable", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.IgnoreCase);

            if ((Convert.ToBoolean(field_info.GetValue(attribute)) != value))
            {
                field_info.SetValue(attribute, value);
            }

        }

In simple words it is working only when we change while loading rest of the times when we change browsable Property value it is not refelecting in propertygrid.

I have a RadCartesianChart with a vertical linear axis.

I want to be able to click on the axis and show a dialog.

I have got it working on the MouseLeftButtonUp event – but it only triggers when I click the labels – and not the background. I have tried to style the axis – but with no luck.

Hello,

I've created a custom resourcetype "rep" and subsequent resources (reps) that are currently different categories on my scheduleview. I now have the view that I want, but i don't know how to add data to the rep property of an appointment so it will be shown in the proper category. Unsure on whether to create my own custom appointments or if this can be bound as is.

Thanks

Hi. I have a RadTabControl, wich ContentTemplate is a static resource with a DataTemplate like this:

        <DataTemplate x:Key="TabItemContentTemplate" >
            <ContentControl prism:RegionManager.RegionName="{Binding RegionName}"/>
        </DataTemplate>

My item view model has a Header property and a RegionName property. All I want is to know the exactly moment all the templates are applied in the RadTabControl, so I can call the RegionManager to create a view inside.

I've tried RadTabControl.Loaded and may others, also have tried to locate ContentPresenter named ContentElement and attach to the Loaded event, but even there the content control is not yet created.

Any ideas? Thanks in advance.

Hi,

I'm creating a ComboBox that contains a Dictionary<byte,string> (for ex.) and ClearSelectionbuttonVisibility = Visible.

It's all ok, but if I click on "Clear Selection", it gives me ad error (that I attached).

I had to declare my property SelectedItem as KeyValuePair<byte, string>.

Now, I think that the reason's error is that KeyValuePair<byte,string> is not nullable, then?

How can I do use Dictionary in this context?

RadMaskedTextInput fails on cut using shift-del.

Just tried your R3 2016 demo and it also throws what seems to be the same exception.

System.Runtime.InteropServices.COMException (0x800401D0): OpenClipboard Failed (Exception from HRESULT: 0x800401D0 (CLIPBRD_E_CANT_OPEN))

First of all sorry if this question is already answered or it is very dummy.

I was using several RadTabControls in my application, but I've reached a point that I need to use a view model istead of a RadTabItem and create them in codebehind on certain conditions for one of the RadTabCotrols.

There is other function that does run through every RadTabControl retrieving all the RadTabItems by looking at the Item property. But it happens that one of my RadTabControls has a custom viewModel, so the cast to RadTabItem fails.

I suppose that it is very logical to get the ViewModel from Items property when you have defined to have a viewmodel and want to run over all items, but I wonder if there is a generic way (accessor, list) of getting just the RadTabItem control that wraps the custom viewmodel and use the same method of running through all RadTabItems for all RadTabControls.

Thanks in advance.

David.
