Is there another way to handle the leave event of multiple textboxes other then coding in each event handler? I may not be using correct terms instead of doing this: (Existing)
Private Sub leveladjstvaltxt_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles leveladjstvaltxt.Leave
If Me.leveladjstvaltxt.Text <> "" Then
Dim levels As Integer = CInt(Me.leveladjstvaltxt.Text)
Me.leveladjstvaltxt.Text = Format(levels, "#,###")
I have 30 TextBoxes all need same formatting , so I was trying to come up with something like this: (trying)
For Each ctrl As Control In Me.Controls
If TypeOf ctrl Is TextBox And ctrl.Text <> "" Then
Dim val As Double = CDbl(ctrl.Text)
CType(ctrl, TextBox).Text = Format(val, "#,###")
End If
I am stuck though and don't know where I would place that code if this is something that is even possible. Only thing I can currently think of is in the leave event which defeats the purpose, I wanted to avoid having to place the code in 30 different textoxes leave event.
how to clear 5 TextBoxes with 1 line code not for every TextBox (TextBox.Text = ""). I tryed many methods, but not successfully.
View 11 RepliesI'm trying to validate a few things in a form I'm building. It has a datagrid with clients info (taken from an access database) and a few textboxes where the user can type some search criteria. The thing is that those same textboxes are used to add new clients to the database and to modify a client's information if one from the datagrid is selected, so I made it that the buttons to insert and modify clients are disabled on load and thenevery time the text on a textbox changes ("TextChanged" event) they become enabled. So far so good. But then I wanted to make it so when a client from the datagrid is selected both buttons become disabled again until the text on a textbox changes (to make sure they're adding a different client and not the same one that was
selected).
I tried using the CellClick event from the datagrid to disable the buttons, but since every time a client is selected from the datagrid the info is shown on the textboxes, this triggers the TextChanged event too, and the buttons become available.So, is there a way I can tell the TextChanged event not to be triggered when the CellClick event occurs?
this is currently my code to clear my 5 textboxes
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
TextBox1.Clear()
TextBox2.Clear()
TextBox3.Clear()
TextBox4.Clear()
TextBox5.Clear()

I want to set the TextChanged event in NumericUpDown box,so that when you press a key, it instantly fires the textchanged event.The default ValueChanged event of the NumericUpDown box does not instantly fire the ValueChanged event. You need to first press the Enter key after you enter a number.And I read somewhere that NumericUpDown box also has a TextChanged event.How do I set the TextChanged event in the NumericUpDown box?

View 8 RepliesI need to know this because I am in a situation that I cannot find a alternative. I am using MaskedTextBox and has a Mask of "__/__/____". Obviously, It's a date format. Now, I cannot get if the MaskedTextBox is string.empty because it is not an empty. I cannot use "If MaskedTexBox.Text = "__/__/____" then " condition also because It never captured. If I used MaskTextBox.MaskFull = false, It gives an error on creating form. So I came up with an idea that would subtitute to TextChanged Event.

View 2 RepliesI was wondering if there's an easy way to make a cell textchanged event for a datagridview, like you have the textchanged event for textboxes, an event that gets triggered everytime the user press a letter/number/symbol/backspace/space, so i can check in that event if the datagridview has changes and whether i should enabled my save button to save the changes made.
Or is there a better way to check whether i need to enable my save button?

I'm not sure if this is possible, but if someone could explain as to why it might be happening.I have a form which has some textboxes: txtDateFrom txtDateTo Where the user would enter the date from and date to that he would like to search for. I've given these textboxes default values in their properties: e.g. txtDateFrom's text is 'Date From' and txtDateTo is 'Date To' . I've then added a onclick event to each of these text boxes informing them what format they need to enter the date :
[code]...
This method however seems to be invoked as soon as the form is opened, does putting a default value for a textbox invoke textchanged? surely not?
I want to modify this code or replace it. I want to override the the textbox's textchanged event in a user control.

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.
