Dear all,

As we focus on any textbox we can change the background colour.

VB

Private Sub TextBox2_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.GotFocus
       TextBox2.BackColor = Color.GreenYellow
End Sub

KINDLY GUIDE IF WE HAVE MORE THAN 25 TEXTBOXES AND WANT TO CHANGE ALL THE TEXTBOX COLUR WITH MOVEMENT OF CURSOR ON THAT OR WANT TO SEE THE LOCATION OF CURSOR WITH CHANGING BACKGROUD COLOUR HOW TO SEE THAT
I have more than 25 textboxes and if I want to change all the textbox color with movement of mouse on that, or if I want to see the location of mouse with changing background color. How to see that?

P.S.: You already used capital letters which is considered shouting and then you increased the font size of it. Avoid it from next time.

Noted sir, keep in the mind from the next time.

With so many textboxes, I would create a derived TextBox control like this:

VB

Public Class SuperTextBox
    Inherits System.Windows.Forms.TextBox

    Protected Overrides Sub OnGotFocus(ByVal e As System.EventArgs)
        Me.BackColor = Color.GreenYellow
        MyBase.OnGotFocus(e)
    End Sub

    Protected Overrides Sub OnLostFocus(ByVal e As System.EventArgs)
        MyBase.OnLostFocus(e)
        Me.BackColor = SystemColors.Window
    End Sub
End Class

Then I would change all the textbox's types (in the designer file) from System.Windows.Forms.TextBox to the derived SuperTextBox class

You can attach the attribute below to all your textbox to get desired result,

JavaScript

onBlur="this.style.backgroundColor='#ffffff'"

Is it? This strikes me as a winforms question - not an ASP.NET question

Solution 1

Write a common method and pass in the name of the textbox. Or track the list of textboxes through a collection.

Kindly explain about that with an example

Possible, but not a good idea with so many textboxes...
