[Solved] Context menu on RadAutoCompleteBox items

Hi!

I'm trying to add a context menu for the RadTokenizedTextItem items in the RadAutoCompleteBox.Items collection. Something like the mockup-image i attached to this post.

The RadAutoCompleteBox itself has both a ContextMenu and a RadContextMenu property, but the RadTokenizedTextItem have none of these.To be clear: I want to be able to right-click an individual token in the RadAutoCompleteBox, click an option in the menu, and then catch some kind of event that includes information about that token in the eventargs. Is this even possible? If so, how would I go about doing this?

I'm using UI for WinForms.

Thanks,

Aleksander

Hiding ToolWindow toolbar?

I have set my Docking.ToolWindow.Text to nothing and the ToolCaptionButtons to None. How can I hide the toolbar altogether? Ideally I would like to be able to programmatically make it reappear on mouse over. Is there a property for this somewhere?

Thanks,

[Solved] RadMaskedEditBox enter currency values without currency symbol without currency symbol

Hello,

In an application I need to enter some large numbers and the client wants to format the number as he types (add currency, thousands separator,etc). I tried to use RadMakedEditBox with the "f" mask, it does not respect culture, I tried using "c" mask, it kinda works but I need to get rid of the currency symbol. With the "c" mask I can change the currency symbol but I am unable to change it to String.Empty as I wish - the control crashes (the closest thing is to set " " - a single space - but it's not very pretty, the client does not accept that).

Is there any way to format the value using culture parameters without currency sign? I also tried working with "p" format but I didn't find a way to hide the percent sign. I seen another thread with a suggestion for using a spinner, that is not good for me.

Thank you.

Export to CSV with programmatically generated grid

I'm trying to use the ExportToCSV function and I can see it works ok with one of my grids, one that was created with the Designer. but when trying to generate a GridView on the fly it'll export a blank CSV, even when the grid's DataSource is filled with records.

01.private void radButton1_Click(object sender, EventArgs e)

02.{

03. RadGridView tempGrid = new RadGridView();

04.

05. GridViewTextBoxColumn firstName = new GridViewTextBoxColumn();

06. firstName.FieldName = "fname";

07. tempGrid.Columns.Add(firstName);

08.

09. GridViewTextBoxColumn lastName = new GridViewTextBoxColumn();

10. lastName.FieldName = "lname";

11. tempGrid.Columns.Add(lastName);

12.

13. GridViewTextBoxColumn emailAddress = new GridViewTextBoxColumn();

14. emailAddress.FieldName = "email";

15. tempGrid.Columns.Add(emailAddress);

16.

17. ContactsEntities csvList = new ContactsEntities();

18. tempGrid.DataSource = (from c in csvList.CSVList select c).ToList();

19.

20. ExportToCSV exporter = new ExportToCSV(tempGrid);

21. string fileName = "D:\\ExportedData2.csv";

22. exporter.RunExport(fileName);

23.}

DataBinding issue with ComboBox

And probably with RadListBox also.

The problem is as follows: I have a RadComboBox, with DataSource, DisplayMember and ValueMember defined. It get's populated just fine:

    
            cmbNewTipoUtente.ValueMember = "ID_TipoUtente";  
        
            cmbNewTipoUtente.DisplayMember = "Designacao";  
        
            cmbNewTipoUtente.DataSource = dt; //<- DataTable

The same RadComboBox has a DataBinding on SelectedValue to a property on a POCO object. Something like this:

    
            cmbNewTipoUtente.DataBindings.Add("SelectedValue", mNewTipoUtente, "ID_TipoUtente", true, DataSourceUpdateMode.OnPropertyChanged, null);

Also have the SelectedIndexChanged event subscribed where I check for some conditions. In the event, I'm checking the value on the ID_TipoUtente property so I can pass it to a method on my business layer. This is where the problem lays (and I think it is a bug), whenever I selecte an item on the RadComboBox, the value of my property do not get updated.

I tryed to open a Bug Report, but it seems there's also a bug on My Account section of the site, since there is only one product available to me, where should be almost all of them. lol

This is a big issue since many of my features are broken because of this and can cause me some pain with my clients.

[Solved] Bind DataRow to PropertyGrid

Hi.

I'd like to bind the DataTable (contains a single DataRow) to radPropertyGrid: each row in radPropertyGrid should represent sequental value from DataRow. As I've understood it is quite possible. But I also want to add IsReadOnly and Category attributes to each property created this way. I have arrays of appropriate length where there each value should be applied to same index's attributes of (DataRow value as Property) in radPropertyGrid.

Moreover I have plans to get changes from this radPropertyGrid to create an update statement for my database.

I'm afraid I'm not quite skilled to complete these tasks without some help as I have some problems with understanding TypeDescriptors, TypeProviders etc.

Could you please give me any tips?
