[.net] VB.Net .Clear() or txtbox.Text = "" textbox clear methods

Not far into programming and just joined this forum of mighty company so this is a silly question, but what is the best way to clear textboxes in VB.Net and what is the difference between the two methods? I have also seen people be critical of folk using clear objects on their forms and I can see why but in this case, I am only learning.

txtbox1.Clear()

or

txtbox1.Text = ""

Any help is much appreciated.

This question is related to .net vb.net winforms textbox

The answer is


Add this code in the Module :

Public Sub ClearTextBoxes(frm As Form) 

    For Each Control In frm.Controls
        If TypeOf Control Is TextBox Then
            Control.Text = ""     'Clear all text
        End If       
    Next Control

End Sub

Add this code in the Form window to Call the Sub routine:

Private Sub Command1_Click()
    Call ClearTextBoxes(Me)
End Sub

If u want to Selected text clear then using to this code i will make by my self ;)

If e.KeyCode = Keys.Delete Then
    TextBox1.SelectedText = ""
End If

thats it


Public Sub EmptyTxt(ByVal Frm As Form)
    Dim Ctl As Control
    For Each Ctl In Frm.Controls
        If TypeOf Ctl Is TextBox Then Ctl.Text = ""
        If TypeOf Ctl Is GroupBox Then
            Dim Ctl1 As Control
            For Each Ctl1 In Ctl.Controls
                If TypeOf Ctl1 Is TextBox Then
                    Ctl1.Text = ""
                End If
            Next
        End If
    Next
End Sub

add this code in form and call this function

EmptyTxt(Me)

Specifically if you want to clear your text box in VB.NET or VB 6.0, write this code:

TextBox1.Items.Clear()

If you are using VBA, then the use this code :

TextBox1.Text = "" or TextBox1.Clear()


The Clear method is defined as

    public void Clear() { 
        Text = null;
    } 

The Text property's setter starts with

        set { 
            if (value == null) { 
                value = "";
            } 

I assume this answers your question.


Just use:TextBox1.Clear() It will work fine.


Clear() set the Text property to nothing. So txtbox1.Text = Nothing does the same thing as clear. An empty string (also available through String.Empty) is not a null reference, but has no value of course.
