In vb.net I would like to set all numericUpDown (NUD) controls to select their value when they receive focus, like a text box does. Do I need to write a GotFocus handler for each NUD? I know I can use widthBox.Select(0, widthBox.ToString().Length) to do the selection I just need to be able to apply this to all NUD GotFocus events.
View 2 RepliesThe problem is that the method is getting called multiple times when the text box control gains focus. I am looking for it to just run once since the method is filling the text box control with data. Is there a common reason this happens? Its not looping cause it is happening on everyone of my controls that use the GotFocus method.
View 7 RepliesI've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.
There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.

I have eight NumericUpDown controls in my form, I call them NumericUpDown_1 thru NumericUpdown 8. I first noticed when I set a breakpoint in say NumericUpDown_1 routine and have code inside this routine to manipulate say NumericUpdown_6's value, the code would immediate jump to NumericUpdown_6 routine because the value changed. This makes sense since the handler fires due to the default handler - numericUpDown_valuechanges. But I do not want this to happen so I removed the handlers for all NumericUpdownX routines, one thru eight and instead I use "addhandler" and "removehandler" statements inside the individual routines to "mask off" this problem every time I change a numericUpDown.Value that is not in it's own routine.
My problem is this does not work. What I found is if I use removehandler numericUPDown_x.valuechange addressof numericUpdown_valuechange statement the coding would work however when I'm done in that routine I follow up with addhandler numericUpDown... statement and I'm back to the same problem. A different numericUpDown routine will fire because I changed it's value in another routine but I had the handler removed before I changed it's value so I don't understand. It's almost like it remembered that it's value changed as soon as I turned back on the handler using addhandler. I'm working with Visual Basic 2010.
I have 10 values to compare against each other for duplicates and would like a recommendation to do this most efficiently. The values are associated with the NumericUpDown control. I'm using VS and VB 2010.

View 2 RepliesI have a mdi and 3 child windows.The program start with an empty mdi.With a menu you can open each child window once.When i open for example 2 windows. And close the one on top. The one left(the window under the one i closed) should get focus. How can i manage this?
why i need this?each childwindow has a event gotFocus. Depending on the focus my menu should change.

I can't seem to get the Form.GotFocus event to fire.I have two forms - a main window and a debug window.The debug window will always be shown with the main window. But, I don't want the debug window to appear in the task bar - it's unnecessary.While my program is running, when I select another program, my main window and the debug window are placed behind the program that I selected. From the task bar, I can bring my program back to the front by clicking on it in the task bar. The problem is, that now my debug window is behind the other program.I have code that will "DebugWindow.BringToFront", and it works. But I need some way to run do this when the main form gets the focus.I do not wish to make any of my forms Modal. At least not permanently. If the solution is to change the modal property of the form temporarily, then that wouldn't be a problem.
I tried Me.Enter, Me.Activated, Me.Click and a few other events. Me.Click only works when I click within the Form window, not the form's title bar. Me.Activated caused problems - The code ran, but it would always end with the focus on the Debug window. When I tried to click on the main form, the Activated event would fire again, sending the focus back to the debug window.[code]
I just added a gotfocus and lostfocus handler for all of my textboxes. Below is my routines to call on gotfocus/lostfocus.
[Code]...
Now, my issue is that this works great if you use the mouse and click around in the textboxes. However, if you hit the TAB key to move around on the screen, the LostFocus event doesn't seem to work. All of my textboxes backcolor remains lightblue. What did I do wrong? What do I need to do to fix this problem?
I know that with the Command Button, you can utilize the PerformClick option. I would like to know how you would go about doing something similar for a Combobox.What I am looking to do is open the Combobox within the GotFocus method.
View 2 RepliesI have two web browser controls on my form. I also have several buttons like bold, underline, etc. My probem is the gotfocus of the web control is not working correctly. If I click on the web browser control to add text the gotfocus is not fired. If I click on a text box first and then click in the browser control it is fired. I need to know which has focused so the bold etc know which control to work on.

I am creating a page in which I need to show a drop down List. From this drop down List a user can select multiple values. I know I could use a check box list like:
<asp:CheckBoxList ID="CheckBoxList1" runat="server" style="margin-right: 158px">
<asp:ListItem>Value 1</asp:ListItem>
<asp:ListItem>Value 2</asp:ListItem>

but if there are more than 50 or so values then that will consume a lot of space on the page and will look odd. So kindly tell me how can I select multiple values from drop down list or if there any alternatives so that I can select multiple values and show many records on a minimum space but not a grid?
