Here's a start... not one line of code but it will work

For Each txt As Control In Me.Controls             If TypeOf txt Is TextBox Then                 CType(txt, TextBox).Text = ""             End If Next

If you really want one line of code:

TextBox1.Text And TextBox2.Text And TextBox3.Text And TextBox4.Text And TextBox5.Text =""

Although I would recommend CharlieMay's way.

Actually you can't. It puts the blue line under it and say "Property access must assign to the property or use its value." I have would with it and tried, after the code was posted of course, that was all that I could think of at the time and I was not able to test it. I have also tried to use And; And Also; and & but they were a not also.

If your textboxes were the default names i.e. textbox1, textbox2, etc... Then this would work:

For i As Integer = 1 To 5    Me.Controls("textbox" & i.ToString).Text = "" Next

Anyway thanks for asnwering

This technique works for frameworks > 2.0. If your are getting an error tell us what it is, and show your code so we can see why this is occurring.

"Object reference not set to an instance of an object."}

Then your textbox name does not match your code, check the names!

All TextBoxes 1-5 have name

TextBox1
TextBox2
TextBox3

and etc...
