Hi folks, this is not a Telerik bug specifically - its a bug (I think) with the underlying base Checkbox and Radiobutton controls that I believe the Telerik controls inherit. Anyway let me describe the issue and maybe someone out there knows why this is...It's not super important its just one of those things that's bugged me for years (this bug has been around since the very first release of Visual Studio.)

I build business to business desktop applications. That means there are a ton of data-entry forms and if you pay any attention at all to quality UI (if you didn't you wouldn't be using Telerik controls!) you like to have your data-entry form elements line up. It's easier on the eyes and far easier for Data-Entry people to keep track of their place. Anyway lets pretend you have a form with Last Name, First Name text boxes and Are you a Supervisor checkbox.

You're not going to just dump the text boxes on the form - you'll have a label preceding the text boxes and a lot of folks (myself included) you'll use a colon to separate the label from the Textbox and to give you something to align to like this:

First Name: [__________]

Last Name: [__________]

Supervisor: [X]

FYI. What I've done in text above isn't possible with two labels, two text boxes and one check box. Don't believe me? Try it.

See the default (for whatever reason) for Checkboxes (and radios for that matter) is to put the data-input portion of the control BEFORE the text so your checkbox would look like this: [X] Supervisor:

So now your data-inputs no longer line up...no problem! Just change the RightToLeft property from false to true right? *wrong!*

That's the bug. If you set RightToLeft = True your checkbox would like exactly like this:

:Supervisor [X]

Yup...that's not a type. The colon gets shoved in front of the text for some odd reason and this is the thing that's been bugging me for over a decade and I've never found anyone who can give me a reasonable answer as to why in the heck Microsoft would do that. BTW the Colon doesn't matter. You can use any punctuation mark or multiple combinations of them - if they're at the END of your "Text" property, they'll get shoved to the front of the line.

I've long ago given up trying to do the above. Instead I use THREE labels, two text boxes and a Checkbox with no Text property then I add the code in for clicks and mouse-overs etc on the label to trigger the same event for the check box.

Again, its silly I know! I'm a new, huge fan of Telerik and thought maybe someone out there knows whats up with this and can reply.

Thanks everyone :)

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,

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.

Custom Nodes in Tree View

Hi Team,

In the Telerik article for Custom Nodes in Treeview, the root node and the child nodes contain the same controls i.e image,label,line,button.

Please provide code for displaying different controls in the root node and child nodes. Eg: image,label,line,button in Root Node, TextBox in child node in level1 and checkbox in child node in level 2

Thanks,
