override appearance/functionality of each tab's remove ([X]) button

I have a tab control and each tab's [x] button (far right of tab strip) behavior is to remove the tab page from the collection.
1) how do I change the [x] to an icon; and,
2) how do I override the event to provide my own functionality (example to delete the underlying object).

RadContextMenu on ListView removing multiple items

I have a RadContextMenu on a RadListView with 2 commands. Add and Remove. The Add works fine, but when I use the remove a few times, It removes the selected Index item in addition to the one above it. The Item.text for the listview items are unique and that is how I am removing them.

Help! I've been fighting this for 3 days. Still clicking remove on 1 item results in multiple items being removed.

A good example of the radMenuItem1_Click event would be very useful.

Thanks,
-Henry

Debug edit and continue (Not Working)

Hi,

Since, I have installed Telerik JustCode on VS2010 (32 bit) Windows 7 32 Bit, when I am debugging I get an Error Message:
Edit and Continue
Changes are not allowed in the following cases:
- When the debugger has been attached to an already running process.
- The code being debugged was optimized at build or run time.
- The assembly being debugged is loaded as domain-neutral.
- The assembly being debugged was loaded through reflection.

I want to have the original ability if an error occurr I can edit and continue.
I think it is caused by the JustCode.

Please Advice how to fix it or how to Disable JustCode.
Thanks.
Regards Dat.

AutoScroll in SplitPanel not working?

Hi, when I set AutoScroll of a SplitPanel to true, no scrollbars appear when I resize the window to smaller size. When I set AutoScroll of the whole SplitContainer to true, the scrollbars show up but the not visible part of container is not displayed and sometimes a lot of black lines appear in this part instead. The SplitContainer is placed in a page displayed in RadPageView in a RadForm. What can be the problem?

Exception on Print Preview

We are getting the attached exception on our remote RDP terminals when a client is trying to print preview document when the terminals have no printer installed.

We need to still have the print preview work as user log into the terminal to view data but the terminal may not have any printers defined (this is on purpose because we don't want them printing documents to our printers)

Is there a work around to prevent this error, but still allow print preview to work?

[Solved] Read Only for all editors

I want to have a readonly functionality implemented in DropDown, DropDownList. Marking them Enabled = False is the most ugly solution. By readonly, I mean to say the equivalent feature of the TextBox. This is most useful for show View-Only Forms. Using a common form for showing information and editing information becomes very elegant if all Editor support readonly. I refer to DateTimePickers and Checkboxes too. Having them set to disable is just not right. Also, having labels and/or readonly-textboxes in the dropdown's place while in readonly/view mode is also more of a head-ache.

Unbound columns

Here is my scenario,

I bind my grid with a List of foo.

foo contains a list of bar, which are custom, user defined fields. Each foo has the identical list of bars, but the "Value" of each bar is different, depending on what the user put in.

In my scenario, foo has a list with 2 bars

bar 1 Fieldname="CustomField1"
bar 1 Value="My Field"

bar 2 Fieldname="CustomField2"
bar 2 Value="My Field 2"

My grid will have 5 columns, ID, Name, Desc, CustomField1, CustomField2.

When I bind, ID, Name, Desc populate with data, but of course, CustomField1 and CustomField2 are empty, which I expect.

What is the best way to get the data into these columns?

I hope this isn't too confusing!

Thanks.

Sample Code;

namespace sample

{

class foo

{

public int ID { get; set; }

public string Name { get; set; }

public string Desc { get; set; }

private List<bar> _customFields;

public foo ()

{

_customFields = new List<bar>();

}

class bar

{

public string FieldName { get; set; }

public string Value { get; set; }

}

Clickable PageView Header

Hi,

I am using RadPageView control configured like in pageview.png.
I would like to add some functionality to Header element like:
1. On mouse over cursor should change to hand.
2. You should be able to click and do some action.
3. When moving between pages text should not be changed.

In summary, the header would turn into a button.

I was able only to change the text by:

((Telerik.WinControls.UI.RadPageViewLabelElement)(this.radPageView1.GetChildAt(0).GetChildAt(1))).Text = "Test";

But events such as MouseOver, MouseLeave, etc. do not work.
