i'm trying make a ContextMenu for my winForms App (VB.NET).
When i click on the form i want yo show a Fading Context Menu (only a white rectangle with a label on it which we can hit and do an action)
So, i created an UserControl which inherits a Form, but when i call the Conectx menu my MainForm lost focus :s (im searching for something like a .Net contextMenuStrip)

I have a TStringGrid, that has a TPopupMenu connected.
By clicking one event of the popup menu, I would like to get the calling component. Is that possible?
Background:
It is a bigger project, every form has a "BasicForm" I can inherited from. So I would like to provide a "default popup menu" for grids that have stuff like Copy, Select, and so on in it. In the inherited form I only match the grid (if exists) with that popup and I'm done.
Seems you are looking for the PopupComponent property of TPopupMenu:
Vcl.Menus.TPopupMenu.PopupComponent
Indicates the component that last displayed the popup menu in response
to a right mouse click.
Read PopupComponent to determine which control is currently using the
popup menu. In applications where multiple controls share the same
pop-up menu, use PopupComponent to determine which of them displayed
the menu.
Set PopupComponent to associate a control with the menu before calling
the Popup method programmatically to bring up the pop-up menu.
I am trying to add an image next to the hamburger menu in my app. I am using a master detail page and it renders fine in ios and android. I tried using setting the icons for the detail pages. but the icons never showed. How do I achive this. I am looking to add an image similar to the amazon app.
I checked out this app on my phone and it uses a lot of custom constructions that aren't supported by out of the box Xamarin Forms controls. Something like the back arrow next to the hamburger menu is not a standard thing (on iOS at least). Also looking at the actual menu that the hamburger button triggers it becomes clear that its not an out of the box hamburger menu. Theirs pops over the content instead of sliding it out of view as the built-in one does.
More than likely they implemented their own hamburger menu and navigation structure which gave them the freedom to add buttons next to it. If you want to achieve this with out of the box controls you will most likely need custom renderers for each platform to create a replica of this navigation structure.
What is built-in in Xamarin Forms is that you can set the page title to an image instead of text by using the NavigationPage.SetTitleIcon method, which could be used to achieve what you want:
public class MyPage : NavigationPage
{
public MyPage ()
{
var myContentPage = new MyContentPage (Color.White);
this.Push (myContentPage);
var s = "icon.png";
NavigationPage.SetTitleIcon (myContentPage, s);
}
}
Even then, this is limited in functionality. If you want to fiddle with the alignment of the image e.g. you would also need to resort to a custom renderer.

I have an separate Add button (neither on toolbar, nor on grid) and I want to open a popup window (having some fields) after clicking this button in order to create a new record. I have a look at the Kendo Demo pages, but all the samples use grid's or toolbar's Create button. Instead of them, a need a sample with a separate button. Any sample please?
Update: I want to create a listview as shown below instead of grid:
If you call dataGrid.addRow() method and edit mode is set to "popup", Popup window will be displayed.

I'm trying to use the Action Manager and Action Main Menu Bar in Delphi 2010 an I have no idea how to make this work. I've tried looking at the examples that come with Delphi 2010 and I can't seem to figure this out.
I've tried playing around with the examples. I've been able to add an image to the Image List component and set that item to the new item index. At design time it displays properly at runtime it reverts back to the original.
I'd like to learn how to use the Action Manager and Action Main Menu Bar but I can find any help on these topics. Is there a tutorial on how to use the Action Manager and Action Main Menu Bar?
Drag and drop a ActionManager, a ActionMainMenuBar and a ImageList on your form.
Doubleclick the ImageList, you get the Imagelist Editor. Use the Add-button to add your icons (make sure their sizes are the same as the Height and Width properties that are set in the ImageList-control).
Set the Images-property of the ActionManager to your ImageList and set the ActionManager-property of your ActionMainMenuBar to your ActionManager.
Doubleclick the ActionManager, go to the tab 'Actions' and add new actions by the 'New'-button.
Click each Action in the ActionManager and set each action's properties, at least: ImageIndex (to choose an Icon), Caption and Category.
Note: A Category will serve as a main item in the menu (like File, Edit and View) and each Action will serve as menu item (like Save, Save as, Load). So set the Category property of all actions you want to belong to one main menu item to the same name. For instance give the actions 'Save' and 'Load' the category 'File' and give the actions 'Undo' and 'Redo' the category 'Edit'.
Doubleclick each Action in the ActionManager. You'll get the code editor. Type the code you want to perform when the user clicks this menu item. If you don't type any code or comment, the menu item will automatically be disabled when the application is running.
Now drag the categories from the ActionManager to the ActionMainMenuBar.
That's it.
I think Actions, Action Lists And Action Managers by Brian Long is a great start to explore the realm of actions.
