Use the Keypress event of your first textbox to get the key that the user is typing. Set keypressEventArgument.Handled to true if key typed is a comma and then set focus to next textbox.

4- e.Handled = True
5- End If
6- If e.KeyChar = "," Then

Try this.
Private Sub Text1_Change()
Dim lCount As Long
lCount = Len(Text1.Text)
For lCount = 1 To lCount
If Mid$(Text1.Text, lCount, 1) = "," Then
Text1.Text = Left$(Text1, (lCount - 1))
Text2.SetFocus
Exit For
End If
Next lCount
End Sub

well this is my code: -
Private Sub Radiobutton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Radiobutton1.CheckedChanged
If Radiobutton1.Checked = True Then
TextBox6.Enabled = True
Else
TextBox6.Enabled = False
End If
End Sub
but it is not working. no errors but not working.

well this is my code: -
Private Sub Radiobutton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Radiobutton1.CheckedChanged
If Radiobutton1.Checked = True Then
TextBox6.Enabled = True
Else
TextBox6.Enabled = False
End If
End Sub
but it is not working. no errors but not working.
|

|
|

set a breakpoint into the function and watch if the function is called...
and watch also if it is going into the right case (maybe Radiobutton1.Checked is not set to what you think...)

i'm still not able to figure out what exactly is the fault. or where things are goin wrong. is there any other way to make a textbox active other than using radiobuttons and buttons.
|
|
|
|
|
hum, no, there no other way.
but i thought to something : isn't your textbox into a groupbox that is itself disabled (Enabled = false) ??

no it's directly on the webform.
|
|
|
|
|
try this.
Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton14.CheckedChanged
Dim rdoTemp As RadioButton = CType(sender, RadioButton)
TextBox1.Enabled = rdoTemp.Checked
End Sub
|

What exactly are you trying to achieve - all the code submitted in this thread works, so I suspect that you may be doing something out of the ordinary. Is a radio button the right control for you remembering that they are grouped.
Perhaps a little more explanation of the task at hand may help in providing a solution that works for you.
|
|
|
|

ok i'll tell you what exactly i'm trying to do. i have a dropdownlist which has a collection of various items. the user has to select anyone from it. in case the user does not find his category of items in the dropdown list then he has to click on the radiobutton which has its text as 'NOT AVAILABLE' which in turn enables the textbox and the user can type in his special category of item. and all these controls are directly on the webform.

Ok. Firstly, apologies,' I didn't realize that this was web based. I am not a web person myself, but the following should work. I am sure some 'true' web people out there will come up with a more elegant solution for you.
Firstly, radiobuttons do NOT cause a post back to the server by default, so you must enable this (AutoPostBack property to true)
Then, you can key this code into your page_load event.
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
<br />
If Not IsPostBack Then<br />
'<br />
' normal code to initialise the form<br />
'<br />
Else<br />
TextBox1.Enabled = RadioButton1.Checked<br />
End If<br />
<br />
End Sub
I am sure that you should be able to achieve the same results via some form of client side script, but as I said - I am not a web person, and the above code worked for me when I tested it !!

no need for apologies raph. it happens after all we are there to help each other. anyways thanx for urs time for my problem and ur involvement. i also found another way of doin it just some logical if else loops helped remove the loop holes.
|
|
|
|
|
If RadioButton1.Checked=true Then
me.TextBox1.Enabled=true
Else
me.TextBox1.Enabled=false
EndIf
I hope this helps to you

Can i set a template collumn in (Windows Form) DataGrid as in (Web Form) DataGrid.
Thanks in advance 
|
|

Not exactly. First you need to create a class based on the DataGridColumnStyle if you want to implement custom appearance or functionality for your columns. You would then create a new DataGridTableStyle and add your new class to its GridColumnStyles collection. Then you add your DataGridTableStyle to the TableStyles collection of the DataGrid.
There are plenty of articles on doing just that. Search for "DataGridColumnStyle" here on The Code Project and you will find plenty of help.
VS.NET 2005 brings a lot of new features to the DataGrid that should make life a lot easier than this.

I have a .exe file developed using windows aplication in vb.net. i want to run it in web application developed in vb.net. The .exe must run once i click on link on the page developed in using web application in vb.net

Well, you can hyperlink to the file, then people will get prompted to download and/or run it. They need to download it before it can be run, and a web app can't run an exe on the client. Your web app code runs on the server, all the client gets is HTML and jscript.
