Which Tab Was Clicked On Tabcontrol MouseClick Event
Feb 12, 2010
I am learning how to develop Windows Forms applications with Visual Basic Express 2008, and my testing/learning application has a TabControl with a few test pages (3, for example, the number isn't relevant here).Now, I am handing the MouseClick event on the Tabcontrol, and I can't seem to be able to figure out how to get which tab was clicked on.I believe that the MouseClick event isn't fired if I click on another place of the tab strip, therefore a tab must have been clicked on. The problem is, which was the tab?
I have a custom (inherited) TabControl which adds Drag/Drop functionality to it, so that one can drag the tabs around, either within the same control (to re-order them) or to and from other TabControls. I've noticed some time ago that my TabControl however was not raising its MouseClick and MouseUp events (or actually: it is not calling its OnMouseClick and OnMouseUp methods, which comes down to the same thing). I've been struggling with this problem for a long while and I finally figured out what is happening. I'm no closer to figuring out what to do about it though... The problem seems related to the drag drop functionality. I have this code in the OnMouseDown method (which is raised as usual):
I have an ActiveX component (for mapping) I am using that I need to do an action on a mouse click, but the event isn't exposed. Internally, the class seems to fire an event, as it has a LastPointClicked() method that you can call that returns the map coordinates of the last point you clicked on. I am trying to find a way to center the map on the point clicked. I could fudge it with some kind of timer that just checks to see if the LastPointClicked has changed and center if it did,
I've noticed that in VS2008 the Mouse_Click() event is not firing for the right mouse button.I create a standard WinForms button called "btnMouseEvents". Wire up the MouseClick event. The event fires for the left button but not the right.
Private Sub btnMouseEvents_MouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles btnMouseEvents.MouseClick MsgBox("Mouse click. Button = " & e.Button.ToString())
Currently, when I double click on my current list, even if there isnt an item at the current mouses location, it calls the event and uses the last highlighted item. I know it is possible to fix this by using a selected index change event, but I require the list items to be double clicked
I have tabcontrol with event tabcontrol_main_selectedIndex.... it's working before until I cut and paste the tabcontrol. When I add event I have tabcontrol1_main_selectedindex still not working how I can return the same name to fire the event added on tab?
how to add a click event to the tabpages of a tabcontrol? I tried double clicking it but nothing happened. I tried putting a button on the tabpage but that did not work either.
I have a tabcontrol with 3 tabs. I can't see where any event is raised when I click the small tab area (where the name of the tabpage is). I see where an event is raised when I click on the tabpage itself. What is the event for the small tab area? I am getting by with a mousemove event over the currently selected tabpage.
Is it possible to assign the MouseDown event handler or equivalent to an image (from ImageList) of a tabcontrol without using OwnerDraw? I can add images to tabs through ImageList. And I can draw something that looks like a close button on each tab, using OwnerDraw. But I notice that the tab sizes will be fixed regardless of the tab labels. I want the tab sizes to be flexible with the labels. For now, the second best alternative to assign events to tabs seems to be use of contextual menus. But it's true that some people just don't want to right-button-click on tabs.And I have seen a project where somebody uses a 32-bit library declare. And I can't use it because I only develop 64-bit apps.
When I click the left or right arrow buttons on the keyboard my tabcontrol tabpage changes from one tab to another. How can I cancel the arrow buttons from changing the tab pages? In other words how can I disable the arrow buttons when the tabpage has focus? Is it possible to do this without extending the base class?
I'm using a TabControl and have overridden the DrawItem event to produce my own background and foreground colors for the header text. It looks good but there's still grey color around each header. I thought maybe the Padding property could be set to (0,0) but that seemed to have no effect.
I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).
I am trying to track which menu item has been clicked in a ContextMenuStrip. I am trying to do so in a ContextMenuStrip1_Click event. I want to track which item was clicked and pass the text from the cliced item to a variable. The code below does not work. I get the following error: "Unable to cast object of type 'System.Windows.Forms.ContextMenuStrip' to type 'System.Windows.Forms.ToolStripMenuItem'."
Any sample code that will cause the logic coded in the clicked event of a Button to be executed, in Powerbuilder I would code it as Button,triggerevent(Clicked!)
How do I program Contextmenustrip item_clicked event in this statement below. I would like when clicked on an item in menustrip the lbl color and lbl text to change
For Each r As DataGridViewRow In Booking.D1.Rows Dim cm As New ContextMenuStrip [Code] .....
I'm having a strange problem with the OnClick event. In an ArcGIS application using VB.Net, I have a button set up with the following
AddItem("CommandAnalyseResults") The following module segment contains the OnClick event: Public NotInheritable Class CommandAnalyseResults Inherits BaseTool <more code...> Public Overrides Sub OnClick()
[Code]...
The OnClick event gets triggered no problem the first time I click on the button. However if I then close the window the button code creates and then click on the button again, the OnClick code is not triggered.
If I click on a different button then click back on the 'problem' button a 2nd time, it does seem to trigger the code!
if a new value of Calendar is selected, it would trigger .SelectionChanged event, but what if same selected value is clicked again? How should i identify it uniquely?
I have a form that I am adding a set of buttons to. I am adding an event to those buttons. I need this event to function slightly to determine what button was pressed.
I need the button to simply set a string variable equal to the clicked buttons text so I can determine what button was pressed.
How can this be accomplished?
''Adding the buttons'' For Each dr In dtMenus Dim strMenuName As String strMenuName = dr.Item("strMenuName").ToString
What I want to achieve is, getting the current position of the mouse when it's clicked on the form (so also on any object on the form)I can get the position with (this code runs in Timer1)
Dim MousePosition As Point MousePosition = Cursor.Position Button4.Text = MousePosition.X & " " & MousePosition.Y
But how do I capture an an overall Click event, so when the mosue is clicked the timer stops?
With the following code, I am creating a child form when my main form loads:
Public Class Form1 Dim cForm As New System.Windows.Forms.Form Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
Once it loads, the main form doesn't seem to handle the mouseclick event. Is that because the child fom is showing, and somehow IT has to handle the click event (even though I'm not clicking within the boundaries of the child form)?
I've been trying to write a utility program that enables you to click a certain number of times and having a specified program open up when that happens. Ex: If I consecutively click 5 times it will open explorer, 6 times will open outlook, ect.I have the entire program writen out, the only things thats stopping its completion is that I can only log clicks that happen ON the form, not on the desktop, or within any window (globally detecting mouse clicks, as opposed to only on the forum
Code: Private Sub Form1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Click
