I have a winform with a wpf usercontrol on it (ElementHost1). The usercontrol contains only a button. How can I know when the wpf button has been clicked in my winform? How can I "redirect" the events from wpf usercontrol to winform?
View 2 RepliesI have a MyUserControl in which I have Button1 and Button2 buttons. I need to "delegate" that button clicks to the MyUserControl's Button1Click event and Button2Click event respectively. Below is a stub I don't really know finishing...
Private WithEvents Button1 As Button
Private WithEvents Button2 As Button
Public Custom Event Button1Click As Eventhandler
AddHandler(ByVal value As EventHandler)
AddHandler Me.Button1.Click, value
End AddHandler
[Code] .....
I wonder if I need the WithEvents in the buttons declaration, and how to achieve the RaiseEvent part...
is there a form event that occurs before the load event in a winforms application? I have a winform app that can be run in batch mode and I don't want the form to load at all. Otherwise I could just hide it in the form load event but I figured there's probably a better way.
View 4 RepliesWhen I look on the Internet I find many want to know how to get MouseWheel events with a UserControl.I'm getting scrolling with the mouse wheel and don't know why.It doesn't seem to be the default since I have other usercontrols that do not respond the the mouse wheel.In one UserControll I find if I move the mose wheel the contents moves. Actully moves too much for good viewing.I've searched the code for "Wheel" - no hits. Also for e.Delts - no hits. Finally I tried:

Commented out as shown I do not get the unwanted mouse moves.If I remove the apostrophe I do get them.
Questions:
Is it OK to not call the Base sub in some cases?How do I find out if it is OK? (For example I don't imagine you'd want to not call it in New()Secondly and most important, What is going on? Why and I getting scrolling with the wheel in a Usercontrol and not getting it in other UserControls?
I would like some code to execute at the "preload" stage of my usercontrol's lifecycle. However the preload event is only available on the Page object. So, I added the following method to my usercontrol:
Private Sub Page_PreLoad(ByVal sender As Object, ByVal e As System.EventArgs) Handles Page.PreLoad
However, I know get the compile error: "Handles clause requires a WithEvents variable defined in the containing type or one of its base types".
As the Page property is inherited from UserControl I don't see how this can easily be done.
A form's key events will fire when you press a key. Place a control on that form and it won't happen any more because that control has focus. There are exceptions to this however as you will see if you place just a h or v scrollbar on the form. The key event will fire because the scrollbars can't receive focus as is demonstrated by the following
Private Sub ScrollBar1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles VScrollBar1.GotFocus
Debug.Print("Scroll GF")
End Sub
[code]....
So I've made my own special scrollbar usercontrol and i can't figure out how to have it leave the key events alone. I'm pretty sure that the problem is that my usercontrol can receive focus at the moment.
I found that the way of doing this is "SetStyle(Windows.Forms.ControlStyles.Selectable, False)". I put that in the new event of my usercontrol and now it looks like this:
Public Sub New()
' This call is required by the designer.
InitializeComponent()
I've created a VB.Net ClassLibrary with a UserControl in it. I can load it from an HTML page and call the methods that I created. This works as expected. I've tried several examples for how to raise an event from the VB code to the js caller, and none of them seem to work (I'm using IE7).

limit the default events, properties and methods exposed from a UserControl so it only displays to the developer the new events etc that I code myself.What i mean is I have created a UserControl with a panel and 5 buttons, written 1 Public Eventonly at this stage, I have placed an instance of the control on a form in a new project, but in the drop down menu that comes up after say (myUserControl1.), there is a massive list of options, I don't want those to appear.
View 3 RepliesI am trying to make a small control that has a picturebox and a few labels that can be dragged on the form it is placed on. The control was easy, and I can drag it fine when the mouse is down on the control, where there are no other controls, like not over the picturebox or labels.
When i try to click and drag the user-control and the mouse is on the picture box or labels of the control the mouse down event is not detected. I am hoping someone can tell me how to pass the mouse-down event from the controls on the user-control so the form I place it on detects the mouse down even no matter where on the control i click.
When i use my UserControl in a project my Mouse Enter & Leave events aren't firing, i assume i fix this with a raiseevents in my usercontrol. However when i try to do this it says something about "cannot raise base event from derived class".

I have a Windows Form that contains a custom control container as a UserControl. For the sake of this question, this custom control container is called Dashboard. This container called Dashboard contains numerous other controls depending on their permissions. I need to raise events that are contained on these controls through the Dashboard control and over to the Windows Form.
How can I bubble up the event? I'm using VB.NET for this project, but can convert C# into VB.NET.Also, to complicate matters, the main Windows Form is a VB6 project. So, I'm using the InteropFormsToolkit to accomplish this.
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.

I have a usercontrol that has a main form and calls another form within the usercontrol to get some data from a database that allows the user to select some items from a CheckedListBox control on the sub form. I want to pass the selected items from the CheckedListBox back to the main form and display the results there. I have a public property called DBList of type List(of String) on the main user control.

I just discovered the joys of UserControl's and I was wondering if it is possible to populate the usercontrol with data from a database in the UserControl's Form.Load event instead of the form the userControl is placed on. I feel it would make using the control a lot easier if it just populated itself without anymore code.I tried it with a ListView but it gave me a bunch of errors, so I didn't know if it had to be done a certain way or if it was just one of those things that doesn't work no matter what.

Explaining what is Redirect Permanent in ASP.Net 4.0?
View 1 RepliesI have a GUI that contains several components (combo boxes, textboxes, etc) with their associated labels. When a button is pressed, the selection in each input component is validated, and if found to contain an invalid value, the label color changes to red and an error message appears. This works fine on its own.The problem arises when invalid values are provided and then later fixed. When the user presses the button and the inputs are valid, I redirect the response to an asp using Response.Redirect, which then runs and opens a PDF report. When this happens, none of the code to change the labels back to their original color or to remove the error message runs. If I change Response.Redirect() to Server.Transfer() and the user goes back, it returns the page to its original state (removing the error messages), but I want to keep the valid data in each component.
What can I do to either remove the error messages when the user goes back or to retain the valid input from the user?Most of the controls are non-standard .NET controls and I'm working with VB.NET 2003.
I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at.
