We have some code in the textCahanged event of a textbox. We only want to fire that code if the user types into the box, not if we change the text in the box programmatically. Can I detect what caused the text to change?

Basically I want to have a textbox (TextBox1) that when you enter an area code (ex. 512) that it will return the state (TEXAS) in the label (Label1). One way that I had been trying before was to reference from a text file the array that I am using which happens to be in the format of 512, TEXAS.
Sample -
TextBox1: 512
Label1: Texas
[Code]...
I would like to use this for multiple area codes and have been unsuccessful in getting it to work.

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.
View 4 RepliesI am using Visual Studio 10 and have run in to an issue that I cannot resolve on my own.When debugging one of my forms the app hangs on a text box control with no errors. But only if you change the text, or press the "Tab" key. The text box is in a group box with a range of other text boxes most with the same properties. All of the controls in this group are connected to an access database record, and formatted to accept the same type(s) of input.Here is the code associated with the control;

I have a TextBox called Social. As you type in a Social Security Number into the textbox, it formats itself into the standard Social Security Number Format (XXX-XX-XXXX). It automatically adds in the dashes after the third and fifth number, or corrects/removes the dashes if numbers are added or removed from in front of the dashes. Also I coded the script to record the caret's location so that the caret goes back to where the caret was before the adjustment in dashes.
I used Pos and PosHold to hold the caret's location.
The problems I am having are:If I remove a number before one of the dashes, the caret is reset to '0' from using break points, it seem to jump out of the if statement before setting the location of the caret. Sometimes when a number is removed from before the dashes, the dashes are removed like scripted but, the dash is not put back in the correct location. This seems to happen primarily if you have numbers passed the second dash.

Windows forms Application. VB .NET 4.0 In my application I have a global boolean variable that keeps track of when changes are made and when they are saved called changesSaved. On closing even it checks the value of this variable before closing the window.. I am using textchanged event to automatically change the value of changesSaved to FALSE when text is changed.. Problem: The group box items are being populated dynamically so the user can edit the values or simply just view them. This dynamic population is causing the textchanged event to fire because the program is changing the text value of the box to put the values in that are stored in the database. The textchanged event should not fire unless the user him or herself enters a value or values in the text boxes..
Is there a way to specify the source i guess you could say for the text changed event or another way so that it will only fire when the user inputs information.??? Functions are as follows: The first is called by the load event to place the values in the box... The next one is the one that is being called as a result of the first one and is also the one that is causing the problems.

View 3 RepliesI have a read-only textbox named txtStartDate in which when the user clicks, a calendarextender will appear and the user can select a date.
Now I have another textbox, txtEndDate, which should automatically change whent the user changes the value in txtStartDate.
But the problem is, the TextChanged event will not work since no postback will occur. When I tried to set the autopostback property to true, I receive a jquery error so I decided no to go with it.
I am using this in my popup usercontrol. Is there a way in which I can trigger a postback so that I can get to change my txtEndDate when the value in txtStartDate changes or when the user clicks on the calendarextender?

For some sort of reason, which I can't seem to spot, this fails and I get a #Name? error. When I tried to do this, I use pretty much the same code in another place in my form; the only difference is the "cbo" and the names of my txt and alike.
