C# - Find Out If The "TextChanged" Event Is Fired If User Is Typing Into A Textbox Or MyTextBox.Text Is Called Programmatically?

Mar 9, 2012

Is there a way to find out if the "TextChanged" event is fired because the user is typing into a textbox or the programmer called myTextBox.Text = "something"? I don't want to react when the user is typing each letter into the textbox so I am using the "Validated" event to catch when the user is done so I can react. The problem is I don't have a way to catch when the programmer does "myTextbox.Text = "something". The only way I know to catch changes there is to use TextChanged but then I don't want to be reacting when the user is typing each letter into the textbox.

VS 2008 : Data Bound List Box, Displaying Data Into Textbox?

Jan 3, 2011

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.

So this is what I got.

Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"

[code]....

It only adds the first rows details to the text box when I click the second record the first rows details are still there.

Responding To A WPF Click Event In A Data-bound User Control?

Oct 15, 2009

I have created several WPF User Controls. The lowest level item is 'PostItNote.xaml'. Next, I have a 'NotesGroup.xaml' file that has an ItemsControl bound to a List of PostItNotes. Above that, I have a 'ProgrammerControl.xaml' file. Each ProgrammerControl has a grid with four different NotesGroup user controls on it (and each NotesGroup contains 0-many PostItNotes.

Then, I have my main window. It also has an ItemsControl, bound to a list of Programmers.

So, you end up with a high level visual view of a list of programmers, each programmer has four groups of tickets, each group of tickets has many PostItNotes.

The trouble I'm having, is that I want to respond to a mouse click event in my mainWindow's code behind file.

I can add a MouseClick event into my PostItNote.xaml.vb file and that is getting called when the user clicks a PostItNote, and I can re-raise the event; but I can't seem to get the NotesGroup to listen for that event. I'm not sure if that's even the correct approach.

When the user clicks the PostItNote, I'm going to do a bunch of business-logic type stuff that the PostItNote control doesn't have a reference to/doesn't know about it.

Access To Bound Data Items From A Textbox / When Text Box Is Not On Form

Dec 20, 2010

In my application, I have a data bound form using a binding control (built by the wizard). The application has one primary data screen plus a few more on tabcontrol subscreens.Picture for example that the tabcontrol has two tabs, tab1 and tab2.When the form is displayed, tab1 is visible.Now picture the form or window split in half the top part of the form has a few textbox controls bound to the data and there are a few textbox controls in the lower half of the screen on tab1 of tabcontrol1.There are a few textbox controls on tab2 as well.When the form displays, I can access any of the .text properties of any of the textbox's that I can see on the form and in tab1 of the tabcontrol.BEFORE tab2 is chosen or even, I need to get some of the data from the .text property on a textbox control that is on tab2.I have tried to get the data but as far as VB is concerned, it does not appear to be there UNTIL tab2 is displayed.

To prove this, I put a command button on the form and it simply does this: MSGBOX (mytext box33. text)mytextbox33 is a databound control on tab2 of the tabcontrol1.tab2 is not in focus and apparently, neither is the data.how can I read the .text property of a textbox that is on a form but the form (or tab) is not in focus?

Load Event Can Not Get Fired At Runtime

Jul 27, 2011

I have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event. Problem here is when i debug the VB.NET application individually the application works fine, Forms Load event is getting fired. But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.

Why this was done i am not sure it was a VB 6.0 code which i have converted to VB.NET. But everything works fine when i debug the application individually on windows 2008 64 bit.

C# - Asynchronously Fired Event Run Synchronously On A Form?

May 17, 2010

[VS 2010 Beta with .Net Framework 3.5]I've written a C# component to asynchronously monitor a socket and raise events when data is received. I set the VB form to show message boxes when the event is raised. What I've noticed is that when the component raises the event synchronously, the message box blocks the component code and locks the form until the user closes the message. When it's raised asynchronously, it neither blocks the code, nor locks the form.

What I want is a way to raise an event in such a way that it does not block the code, but is called on the same thread as the form (so that it locks the form until the user selects an option.)

Update Event Isn't Fired In A Dynamic Gridview?

Feb 20, 2012

I'm creating a dynamic gridview in vb.net using a connected sql database. Everything works fine except 1 thing: when i click the update command, the event just won't fire no matter what I do. the gridview goes into edit mode and the cancel button works fine. This has cost me over 2 days of googling but none of the solutions work. I used breakpoints to check if the code was executed, but it wasn't. If anybody has any experience in this:I believe the problem lies in the addhandler but it doesn't give any errors.I forgot to mention that the sql command was a test and sets the data in that field to 15, now it's 10, it works when i use a normal button or a static gridview.

Let me explain the situation and share some of my code which I'm sure will be horrible since I'm an amateur. I created a class to take in the settings for running a process in the background. I add some custom events in that class so I could use that in my form instead of a timer.

Interface And Graphics :: Resize Event Not Fired When Form Loads?

Nov 4, 2009

Back in the VB6 days, I could count on frmWhatever_Resize() to be fired when a form is loaded. That doesn't still seem to be the case. Since my resize event is filled with all the code I want that adjusts the size and placement of things, I decided to just call it from the end of the form's load event. That has no affect. I'm guessing that the form isn't actually shown until form_load is finished?

is there some other event that is fired when a form is shown, so I can call my resize code there?
