I created this user control that has various linkbuttons to other parts of my web application. I want to disable some of the linkbuttons so that users can't access other pages. I have tried various different ways but as of yet no joy. I have made the linkbuttons in the usercontrol.ascx public so all i really need to kno is how to disable them from the .aspx page.
Any advice is greatly appreciated.

hi there,
what problem u got when trying to disable linkbutton?
it's ok with me but just for asp button, not try with linkbutton yet.

|
|
Basically whenever i put the line in
usercontrol.linkbutton1.enable = False
it won't set the enabled property to false.

how about if u put the link button in web page not in usercontrol?
it would be better to find out the cause if u can post the snippet of code.

ok below is the code for the USER CONTROL
Imports System.Data.SqlClient
Public Class Topmenu
Inherits System.Web.UI.UserControl
Public WithEvents LinkButton1 As System.Web.UI.WebControls.LinkButton
Public WithEvents LinkButton2 As system.Web.UI.WebControls.Linkbutton
Public WithEvents tbltopmenu As System.Web.UI.HTMLControls.HTMLTable
Dim conn As SQLConnection......
Public Sub Page_Load(....)
End Sub
Private Sub LinkButton1_Click(....)
Response.Redirect("menu.aspx")
End Sub
Private Sub LinkButton2_click(....)
Response.Redirect("logout.aspx")
End Sub
End Class
And this is the code I have in the Page_load event on a number of .aspx pages
Public Sub Page_Load(......)
topmenu.Linkbutton1.Enabled = False
End Sub

hi there,
there are couple of articles about this on CP site. below is just one of them
http://www.codeproject.com/cs/media/Aumplib.asp
But this one is the C# one. so u need to port to VB/VB.net yourself 
<< >>
|
|
|
|
|
I'm also looking for this type of ability, but in VB, as my knowledge to convert from c++ / c# is lacking.
I would like to be able to open a wave, convert the sample rate, etc, and save it out as a wave, and possibly an mp3.
Any help would be greatly appreciated.

How to get barcode data from Barcode Reader
thanx in advance
|
|

Barcode readers usually work exactly like a second keyboard. Unfortunately, you usually can't tell the difference between what is being types and what is being scanned.
That problem is easily solvable because most barcode scanners will let you specify a preamble and/or postamble so you can assume that whatever is comming between these characters is being scanned.
Your best bet is to get with the documentation on the scanner, open Notepad, then start playing with the barcodes you have to scan.

Hai,
I am beginners of vb.net.
I want to open word or notepad or any exe files through from the vb.net link.
How it is possible?
any body knows give some idea to me.
|
|

|

If nobody offers a better idea, this is how it was done in vb6. Perhaps you can use this as a starting point:
Private Declare Function ShellExecute Lib "shell32.dll" _
Alias "ShellExecuteA" _
(ByVal hwnd As Long, ByVal lpOperation As String, _
ByVal lpFile As String, ByVal lpParameters As String, _
ByVal lpDirectory As String, ByVal nShowCmd As Long) As Long
Private Const SW_SHOWNORMAL As Long = 1
Dim nResult As Long, pathName As String
pathname = <whatever you like>
nResult = ShellExecute(Me.hwnd, "Open", pathname , 0, 0, SW_SHOWNORMAL)

There is a method which runs .exe files or .bat files etc in vb.net.
System.Diagnostics.Process.Start(<give the="" path="" of="" exe="" file="">)
here the code try this
Add a linklabel to a form and on linkclicked event write this code
System.Diagnostics.Process.Start("notepad.exe") 'This would open a notepad
and if you want to open a WordPad. Then in place of "Notepad.exe" write "WordPad.exe"
-I Hope This Helps

take a dataset fill it using a DataAdapter the assign this dataset to grid's datasource property.
When ever you save the data then first call dataset.clear() it would clear existing data in dataset, then refill the dataset using DataAdapter and reassign dataset to grids datasource.
this would prevent showing repetative entries in grid.
