you see images attached to this control. do you know what the name of this control ? Have DevExpress got this control ? [IMG]http://imagizer.imageshack.com/img673/6260/TV6dOt.jpg[/IMG]
If I am not mistaken, this can be easily achieved with the basic WPF grid system. First row is a header, the separation line is just a row which span all columns.

How can you right align a Devexpress grid label?
I have tried to set the following as suggested by devexpress
settings.Styles.Cell.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Right;
But this just sets the cells to right align.
I have also tried to override the css for the label but the column that has the field that I want right aligned doesn't have an ID so I cant set it in css.
I am using Visual Studio 2013 , C#, Devexpress V13.2.9, and Razor pages.
I used the following in the View:
col.HeaderStyle.HorizontalAlign = System.Web.UI.WebControls.HorizontalAlign.Right;
You will probably need to change 'col' in the above code. The above is cut and pasted from my code and it behaves as desired.

I would like to add an icon to the header of my data grid as it is done in Thunderbird.
There is an icon that is above the vertical scrollbar, no matter the position of the horizontal scrollbar. This icon allows the setup of the columns.
In Delphi there a lot of different grid components, that allow customizations and adding icons to there cells / header cells. But I could not find any component that has an area above the vertical scrollbar that is fixed, which when clicked allows some action. I could even use the VirtualTreeView component to emulate the grid, if it turns out to be easier to customize that component.
I am looking for some guidance on what need to be done to get that functionality.
Thanks,
Thomas
VirtualTreeView in Listbox mode would be nice, because of it's speed, great documentation and ease use in MVC-like patterns. Delphi tempts to store data in the visual components themselves, which letter causes troubles. While VTW allwos the same, it also allows to acutally separate data from GUI, and i like it.
But i am surprised by your claim "which when clicked allows some action.".
Even most basic components allow it:

So could you make more detaiils, why you cannot use standard components ? with screenshot and editors, how u want it rendered, where you want to click and what kind of action should happen ?
I cannot seem to align the DevExpress controls in the Razor view. No matter what div and span combination I use, whenever I use #Html.DevExpress().TextBox the next controls always goes below. I want to display several labels and text boxes horizontally, one next to each other.
Thanks.
Use recommendations from the Possible ways of arranging DevExpress controls within a page KB Article to resolve this issue.
I have a application that like firefox, can be enhanced from plugins available from internet.
Now, I want to provide in Delphi (2010) a dialog similar to the download from firefox. I have no skills in build graphical controls.
Using the standard controls of Delphi, what could be the best way... using a TListView/TStringGrid with custom draw or...
The idea is show a icon in the left, a title with subtitle with 1-3 lines on the middle and date/version on the right. That row must be selectable and that is all.
For the UI part,
The easiest way: Use TNextGrid in "Slide view" from bergsoft. It's one of my favorite VCL controls. Check this screenshot:
http://www.bergsoft.net/res/screenshots/next-grid/slides-style.gif
The most flexible way: Use TVirtualStreeTree with custom draw, but it'll take some time to get use to that most powerful tree view control and apply a custom draw.
The Most promising way: Use TMS software's advanced poly list (in beta stage currently), check the Screenshots in the following page and it's very nice looking!:
http://www.tmssoftware.com/site/advpolylist.asp
use VirtualStringTree from SoftGems.
Use TFrame to create a custom control for one download, and then reuse it.
Use a TDataSet descendant (eg. TClientDataSet, JVCL's TjvMemoryData or any other dataset you like) to have a table with all the fields needed to describe your download. For example:
Plugin_Name - Char(255)
Plugin_Icon - Blob
Downloaded_Size - Int64
Total_Size - Int64
//etc.
(Of course the above fields are provided just as an example - the actual fields are up to you).
After this, connect a TDataSource to your table and use an TDBCtrlGrid to show your data as you wish. For the above example, you can put on your record a TDBLabel, TDBImage, TjvDBProgressBar (unfortunately we don't have a data-aware gauge shipped with Delphi) etc. all these connected to the appropriate fields.
In this way you can simulate a list (if you set TDBCtrlGrid's Column property to 1) with a custom layout in which you can do select, add, delete etc.

My aim is to update the look of the GUI in my app. Currently my GUI contains a lot of listboxes which are used to edit some objects in an old fashioned way, that is, user double-clicks an item and a dialog is shown to modify the corresponding object.
I think a good modern approach is how Firefox displays the extensions installed (a snapshot below).
My question is about how to build such a GUI in Delphi(win32) easily? Are there any components you use mimicing such behaviour or will I just need to code this from stratch using panels? (IMO a very cumbersome job I'd like to avoid - the selection logic, resizings, etc...)
You can do something similar (not exactly) with standard components; TDBCtrlGrid, TSpeedButton,...

If you're using Delphi 2007 or Delphi 2009, you might be able to do something similar using TCategoryButtons (from the 'Additional' component palette page). Drop it on a form and right click to display the popup menu, and then click "Categories Editor...". Add a category with the resulting dialog, set it's caption, and optionally set up Items it contains. Not exactly the same, but it might do what you need.
You could also use a dialog with a TTreeView (if you have categories of objects) or TListView to emulate the Delphi 2007 Projects->Options dialog. Clicking an item in the TreeView or ListView displays the proper page of a TPageControl to configure the object.
I mostly agree with Lars, but I would use a frame for each item instead of a panel. That would separate into its own file, and you would get easy designtime support for it.
Using a TFrame for each list item and put them all Aligned Top on a TScrollBox might work. Also see TDBCtrlGrid which does something like that in combination with datasets.
It can be done with existing Delphi controls.
For instance in the TCustomListBox control you can create your own OnDrawItem event to draw your own list item. You also need to create your own OnMeasureItem to change the item height.
In some cases it is very limited, so if you want more freedom you will need to do it from scratch.
