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.

How to add validation code to appointement change ?

Hello Telerik

I need your help for a particular point in using the RadScheduler.

The appointement displayed in my Scheduler should start and end at some specific time values. The start time should be(08:00;10:00;13:00;15:00) and the end time should be (10:00;12:00;15:00;17:00).

When an user modify one appointement (in all way), I want to check if the start and end times are correct. If not the value should be round to the nearest legal value (cancelling the operation with a message box is also an acceptable solution).

Exemple: If the user set the start time to 9:00 the value is corrected to 08:00.

I have tried to use the Appointements.CollectionChanged event of the Scheduler to change this. But if I correct the value at this time, the scheduler does not update correctly. (The text inside the appointement is changed but not the graphique square. You can see it in the attachement). How could I fix it?

As adding validation rules in a changed event is never a good idea. If you know a way to prevent the user draging or realesing the mouse at an illegal time. It will be perfect !

Checkbox in header?

Hello,

I saw in the asp.net/ajax online demo that you can put a checkbox in the header for a select all type of action. Can that be done for the winforms version? If so I have not been able to find it.

Thanks,

Warren
