I am populating a textbox (txtFileNature) with a value from a popup window. The textbox has an onfocus handler set to
onfocus=("this.blur();")
The problem is that I want to do some calculations based on the value of txtFileNature and want to display the result below it. In which event can I can use my VB code. I can't use the textchanged event since I am not typing in the textbox.
This is one of those "seems obvious" as how to do, but came across interesting side effect in implementing. I'm trying to keep two text boxes syncronized when information is updated. In this example, I will be using txtStartDate and txtEndDate. If the txtStartDate is changed, then the txtEndDate should should be updated. Likewise, if the txtEndDate changes, I want the txtSartDate to be updated. The side effect I'm comming across is that when I set them up under the TextChanged event for both, the events seem to retrigger against each other indefinately (endless loop?). Am I using the wrong event? Is this a task for a delegate?
View 3 RepliesI am trying to do implement an autocomplete textbox in my application and I have a question about keypress event inside an autocomplete textbox. I have 2 textbox namely textbox1 and textbox2. Suppose to be, when the user pressed the RETURN / ENTER key, it will focus on textbox2. how come that on this event is not triggering.
Code:
Private Sub frmCheck_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'set autocomplete mode in textbox1
TextBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend
TextBox1.AutoCompleteSource = AutoCompleteSource.CustomSource
[Code] .....
Also, I would like to ask if how to validate the input if the value from the textbox matches from the autocomplete values. How can I compare the values of the textbox and the autocomplete source?
I'm using a textbox to define a hotkey, and I need to make the textbox receive key events and prevent the form from receiving them.The reason it's a problem is because Tab (and probably other keys) is a valid key, but the form uses that as a shortcut, so the textbox never receives the keypress.

View 1 RepliesI know you can validate textbox text by using the keypress events. But the form i'm working on has multiple groupboxes with multiple textboxes. So rather than having a sub routine to validate every groupbox, i was wanting to have just the one keypress event that handles the textbox entries, and depending on the textbox calls a specific validation routine.[code]
View 2 RepliesIn order to take advantage of the spell checking ability of WPF textboxes, I have added one to a user control (with the use of elementhost). This user control is used in various window forms. My current problem is trying to handle keyup events from this textbox but the windows form is unable to "get" any event from the control. I can access the properties of the textbox just fine (i.e. text, length, etc.) but keyboard events don't seem to work.I have found, however, that the following will bring back events from the WPF textbox:
Public Class MyUserControl
Private _elementHost As New ElementHost
Private _wpfTextbox As New System.Windows.Controls.Textbox
[code].....
The user control is now able to do something after the PreviewKeyUp event is fired in the WPF textbox. Now, I'm not completely sure how to have the window form containing this user control to work with this.
I have a TextBox which Is allowed only to read certain characters. I use KeyPress event to handle this event. I understand that The KeyPress event does not handle the pressing of the DELETE key on the keyboard. I do not want the user to be able to delete characters in the txtbox by using the DELETE key, I want the user only to be able to use the backspace key. I am writing this code in Visual Basic 2005. The following code appears to work in handling the DELETE key, but I am concerned that I might get bitten by the fact that I am using KeyDown and KeyPress on the same control (txtSource).
private sub txtSource_KeyDown(byval sender as object, byval e as KeyEventArgs) handles txtSource.KeyDown
IF e.KeyData = System.Windows.Forms.Keys.Delete then
e.handled=true
end if
end sub

I have some code in a label's mousemove event that allows it to be dragged around my form while the left button is held down. While this is happening none of the other controls on the form respond to their own mousemove events as the mouse pointer passes over them. Is it possible to make more than one control respond to mousemove events at the same time?
