Here, we will see How to disable button click
in ASP.NET.
For example:
Create a web
form having a login and password field and a login button. If login and password
goes wrong for three times then disable the login button and give the message
"Your Account is Blocked"
Double click on the
Button control and add the following code.
VB code:
Protected
Sub Button1_Click(ByVal
sender As Object,
ByVal e As
EventArgs) Handles
Button1.Click
If
Not (TextBox1.Text =
"abc" AndAlso TextBox2.Text =
"xyz") Then
If ViewState("ec")
IsNot Nothing
Then
count = Convert.ToInt32(ViewState("ec"))
End If
count += 1
ViewState("ec") = count
Label1.Text = "count is " & count
If count = 3 Then
Button1.Enabled = False
Label1.Text = "Your Account is blocked"
End If
End If
End Sub
