selecting text in the text box

I have a form with text boxs on it
whenever i enter(got focus) the textbox i want the text in it to be get selected
i can use textbox.selstart and textbox.sellenth but have many text boxs(48)
do i have to write it for each and every text box

(using VB net)
Please help

you could add a handler for all the textboxes , then use SelectAll() , eg:

VB Code:

[Color=Blue]Private[/color] [Color=Blue]WithEvents[/color] tb [Color=Blue]As[/color] TextBox
 
    [Color=Blue]Private[/color] [Color=Blue]Sub[/color] Form1_Load([Color=Blue]ByVal[/color] sender [Color=Blue]As[/color] System.Object, [Color=Blue]ByVal[/color] e [Color=Blue]As[/color] System.EventArgs) [Color=Blue]Handles[/color] [Color=Blue]MyBase[/color].Load
        [Color=Blue]Dim[/color] ctl [Color=Blue]As[/color] Control
        [Color=Blue]For[/color] [Color=Blue]Each[/color] ctl [Color=Blue]In[/color] [Color=Blue]Me[/color].Controls
            [Color=Blue]If[/color] [Color=Blue]TypeOf[/color] ctl [Color=Blue]Is[/color] TextBox [Color=Blue]Then
[/color]                [Color=Blue]AddHandler[/color] ctl.Enter, [Color=Blue]AddressOf[/color] tb_Enter
            [Color=Blue]End[/color] [Color=Blue]If
[/color]        [Color=Blue]Next
[/color]    [Color=Blue]End[/color] [Color=Blue]Sub
 
[/color]    [Color=Blue]Private[/color] [Color=Blue]Sub[/color] tb_Enter([Color=Blue]ByVal[/color] sender [Color=Blue]As[/color] [Color=Blue]Object[/color], [Color=Blue]ByVal[/color] e [Color=Blue]As[/color] System.EventArgs) [Color=Blue]Handles[/color] tb.Enter
        [Color=Blue]Dim[/color] txtbox [Color=Blue]As[/color] TextBox = [Color=Blue]DirectCast[/color](sender, TextBox)
        txtbox.SelectAll()
    [Color=Blue]End[/color] [Color=Blue]Sub[/color]

You could Also make your own control :

Create a new class myTextBox that inherits the class TextBox :

VB Code:

Public Class myTextBox
      Inherits TextBox
     
    Private Sub Enter(ByVal sender As Object, ByVal e As   System.EventArgs) Handles mybase.Enter
        mybase.SelectAll()
    End Sub 
 
 
End Class

Re: selecting text in the text box

Is there a special trick for when a user clicks into the text box? 'Cause i can't get it to select everything when a user clicks in the text box.

Code:

Private Sub TextBox2_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.Enter TextBox2.SelectAll() End Sub

It does select it. You can copy it to another Text field. It just doesn't highlight it.

Hi,

"tHANKS A LOTS I WILL TRY SELECTALL()"

But you will still have to enter it a lot of times, or put a a lot of handles on.

Matt3011's suggestion means you do not have to write the code more than once.

Re: selecting text in the text box

Any help in figuring out how to highlight the entire text in a TextBox when a user clicks in the text box? :confused:

Nothing i try will highlight the text (when a user clicks into a text box).

I've had no success with that either, but there must be a way. If we get no joy on this thread I will start a specific one.

You have not indicated to which of the replies you are referring.

I repeat:

If you use Matt3011's suggestion you will only have to enter the code once.

Do you object to that?

Hi,

Looks like the ONLY event which doesn't highlight the text when you use SelectAll() is the GotFocus :wave:

Try it in Click, MouseDown, MouseUp etc.

With acknowledgments to Brownmonkey :wave:

Re: selecting text in the text box

The GotFocus/Enter events don't work with SelectAll when you click into the text box. So i created a special procedure that i call from the MouseHover event.
