I have a form in my hands with listbox on it. There was a demand to display horizontal scrollbar for this listbox since users are unable to fully read text in the right column.
Is there any way to do so?
how does it looks
desing of subform
Try to get rid off Layout and use table instead.
It seems to be limitation of layouts. It works if you do not use Layouts.
Here is how my subform looks like:

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.
does any one know if there is an example available for sliding panels in jquery? If so, can someone send me a link? This is what I want to accomplish.
On my main screen I want to have three divisions. One right column that covers half the screen and then the left column divided in two rows. I want to expand and/or shrink the right column and/or left column and/or the top row in the left column and/or the bottom row in the left column.
Think og it as an IDE with the left side of the coding area and right side as project explorer and the properties. The coder would like to see any three of the sections at once or would like to expand each working area.
I am looking for a jquery solution for such!
Thanks
Sounds like the way jsfiddle.net works
This is available as a plugin. http://docs.jquery.com/UI/Resizable
You could also use the jQuery splitter plugin: http://www.methvin.com/splitter/
Also see (2011): http://jcubic.wordpress.com/2011/03/06/jquery-splitter-split-container/
Flexigrid is a new (2012) option: http://flexigrid.info/
The most robust solution for this is to use the jQuery layout plugin. You can find it here: http://layout.jquery-dev.net/
We have developed a software. In this software we are show and hiding a few controls on various input screens depending on various situations.
When we hid a control what happens is that the space occupied by that control is left as it is and layout looks very bad at times esp. in screens that have larger numbers of controls. Our client does not like this and has asked us to do something about this.
My question:
Is there some way by which we can create Fluid Layouts so that when a control is hidden the rest of the controls automatically adjusts themselves to fill the empty space left by the control hidden and when the control is show they should automatically make way for the control and adjust themselves accordingly.
I know we can achieve this by coding but that will require a lot of code in each screen for adjusting the layout. I am looking something which will reduce coding in each screen as there are 80+ screens.
Please suggest some way which is less error pron and can get rid of unnecessary coding in each input screen.
I think your best option is to use a component that handles the layout of your vcl controls on your form in runtime (depending on the conditions that you define). I recommend you try the Devexpress ExpressLayout Control
you can find two great demo videos here
ExpressLayout Control - How to Customize Layout Views
ExpressLayout Control - Create and Customize a Simple Layout
(source: devexpress.com)
You can check these features
Auto-Management - Control groups and individual control elements are automatically managed by the Layout Control. You never worry about pixel-by-pixel positioning.
Form auto-sizing - The form can be automatically resized to fit its contents best.
Bye.
Now, I'm not sure how complex layout you have, but I guess you can use TFlowPanel and/or TGridPanel for this. Flowpanel has a nice handling of components that change visiblity. I'm not sure how well gridpanel handles the same...
What kind of controls are you dynamically hiding, and what do you mean with auto fill space?
I do not know if it is as this simple: place controls on panels, and use align alTop/alClient/alBottom. When you hide a panel, all other panels will move automatically up.
One problem though: if you want to show a panel again, the order of panels can sometimes be screwed up... Can be fixed by manually setting .Top property, or "hide" by setting .Height := 1;
What I would do with a complex layout is actually split it up into several tabs. This has two advantages. It simplifies the form layout, and allows you to show and hide whole tabs depending on choices made in other tabs.
Raize Components have a TRzFlowPanel UI component. Does exactly what you're after.
Use TRzFlowPanel to put an empty flow panel on a form. The major difference between a traditional panel and a flow panel is the way in which controls are placed. With a traditional panel, you place a control (such as a button) in a specific location. You can freely move that control to any location within the panel using the mouse. In a flow panel, each control is placed in a specific location, regardless of where you place it with the mouse. The automatic location is controlled by the FlowStyle property. For example, using the default FlowStyle property of LeftRightTopBottom, the first control you add to the flow panel snaps to the top left corner. The second control that you add snaps next to the first control, and so on.
I have a Silverlight DataGrid and I have set the ItemsSource to an instance of PagedCollectionView (I'm wanting to paginate my data with DataPagers).
I've noticed that the vertical scrollbar disappears when using the PagedCollectionView - which is a problem for me because I have the DataGrid nested inside of a Grid in which the RowDefinition.Height is set to Auto (I want my DataGrid to be as big as possible). Now the DataGrid extends beyond the window. I still don't see the Scrollbar when I set VerticalScrollBarVisibility="Visible" on my DataGrid - just a gray strip where it should be.
Does anyone know how I can use PagedCollectionView without having to explicitly specify the height of the DataGrid?
EDIT:
Woops - this was my fault. I can't remember what I did wrong (I figured out my problem a week or two ago), but it had something to do with me not paying attention to the surrounding layout.
Thanks,

This is nearly always related to the container of the grid rather than the grid itself. A real pain. There are lots of good references for understanding and refreshing your knowledge on the layout system:
