Hello
I add a RadPanorama on my form.
Then I open the "Element hierarchy editor"
If you pay attention to the left column, you can see two FillPrimitive under RadScrollBarElement.

The bug is because we have two same name here, there is no access to the second FillPrimitive items from code.

For example to changing the Backcolor and BackColor1 and BackColor2 and BackColor3 of ScrollBar, you can change it from hierarchy, but it is not possible to change it via code.

I attached a screenshot of what I explained example.




Also on RadTitleBar, we have same bug.
I mean there is no access to text via code.
For example it is not possible to access text visibility on title bar via code.

Thanks.

Hi,

I am wanting to know if its possible to make a Menu Item contain a grid of buttons such as the Labels TextAlign PropertyGrid menu in Visual Studio as per attached pic? 

Or is it possible to put a User Control in a Menu Item?

Thanks.

Hi,
We need a cell double click event on our pivot in order to get the values on that row and column. Our pivot's sample is attached.
We tried the code block below. But did not work. Can you help about this. Our product version is 2013.1.220.20

Is there any way to make the expand/collapse plus sign float towards the top-left of the node item?  We can set the text with:


(that code is within the NodeFormatting event, btw...)

So I'm wondering if there is an equivalent function for the expand/collapse element.  It doesn't look right sitting in the center of a node whose height is set to allow for multiple lines.  Would look better at the top-left IMO.

Thanks,

Wayne

Hi
I added a RadPanorama to my form.
Now what I want is the ScrollBar, Be at the middle, not be at the top.
I mean I need my page to be at middle.

What I did is go to Element hierarchy editor, then from the left column, I selected RadScrollBarElement.
Then from right column, I set the Value to 50

This works fine in my Designer window, but when I run, it doesn't work.
Please see the attachment.

Would you please help me?

Thanks.



I should add that I tested RadHScrollBar and RadVScrollBar with the same way I explained, and they worked fine.
It seems there is bug in panorama scrollbar.

Hi there,

We have a data-bound RadGridView to which we’re programmatically adding rows. The position in which the rows are added naturally depends on how the grid is sorted. Is there a way to override this behavior, however? We’d like to insert rows at the end of the grid even if this violates the order in which users have manually sorted the grid.

I’ve tried using a BindingList in order to more closely manage the insertion order, but to no avail.

Thank you so much!

Cheers,
Ben Leibert

Hi,
i use raddock in my project.as u know when it show(open) a form it becomes a tab in raddock.
my problem is that when i open a form and number of open tabs(forms) got more than the width of raddock, it automatically set new opened form in front of other forms.though , i set DocumentInsertOrder to ToBack.
when number of open forms are less than raddock's width, DocumentInsertOrder  works correctly and add new forms to end of active forms but when number of open forms exceed raddock width, it seems that this property act as InFront and add new forms in front of other forms.
i want to add new forms always at the end of active form list even though number of open forms exceed raddock width.
i'm in hurry, please help me
tanx in advance
