Hi
I have four questions:
1. How can I make transparency drop down menu in RadMenu items?
2. How can I make transparency drop down menu header ?
3. how can I change the color of selection of buttons? I mean when mouse moves on buttons, it appears yellow. I need it to be appear green.
4. How to make disappear the drop down header line? I mean if you pay attention to the drop down menu, you can see a vertical band at the left or right side of the drop down menu, depends on right to left setting. I need this band to be disappear like a very simple drop down.
Thanks

Hello,

I am programatically trying to add an arbitrary number of checkboxes (RadCheckBoxElements) to a Vertically aligned ButtonGroup in a RibbonBar. The problem I encounter, is when the number of Elements exceeds three/four, the elements appear 'behind' the edge of the ribbonbar: the list of elements is not continued in an imaginary adjacent column, if you will. In a textual representation, this is what I have now:

===Bar===
[ ] CheckBox1
[ ] CheckBox2
[ ] CheckBox3
===Bar===
[ ] CheckBoxn (appears partly or wholly below bar edge)

What I want to achieve is:
===Bar===
[ ] CheckBox1  [ ] CheckBox4
[ ] CheckBox2  [ ] CheckBoxn
[ ] CheckBox3
===Bar===

Could you help me with this? Thanks in advance!

Hi,

How can I add image on the right blank side of the ribbon. I Attached a screen shot for clarity. Thank you.

Best regards,

Ian

i want a code for inserting image into rad grid in winforms wqith c# where i inserted a binary type image in sql server...so plz help me in this..

In the Windows TreeView, in the BeforeSelect event, the TreeViewCancelEventArgs has a property called Action. So I can check e.Action, and if the source of the action is code, or user input, I can take the appropriate action.

The closest thing RadTreeView has for this event is SelectedNodeChanging. However, the RadTreeViewCancelEventArgs doesn't have an Action property. When using a RadTreeView and handling the SelectedNodeChanging event, how can I determine the source of the selection change, whether by code or user input?

Hello

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.
