How to get the Name Of Multiple TextBoxes Using For Each Loop

[EnigmaticallySpeaking]

In this tutorial I will teach you how to get the name of a specific TextBoxes by using For Each Loop in VB.Net. This method will determine what are the names of your TextBoxes that you drag it on the Form. You will be able to find out the specific name of the TextBox because it will be seen in each TextBoxes.

So let’s begin:

Open Visual Studio and create a new Project. Drag all the TextBoxes and a Button. Then, do the Form just like this.

Double click the Button to fire the click

event handler in the Method.

Now, create a variable that represents the control.

1. Dim
   
   txt As
   
   Control
   

After that, Loop the control that you have created.

1. For
   
   Each
   
   txt In
   
   Me
   
   .
   
   Controls
   
2. 
   
3. Next
   

Then, check if the type of the control is a Textbox and if it’s true, then perform the process that puts the name of the TextBox to itself. Do this code inside the Loop.

1. 
   
2. If
   
   txt.
   
   GetType
   
   Is
   
   GetType
   
   (
   
   TextBox)
   
   Then
   
3. txt.
   
   Text
   
   =
   
   txt.
   
   Name
   
4. End
   
   If
   

And here are the codes that we made.

1. Private
   
   Sub
   
   Button1_Click(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Button1.
   
   Click
   
2. Dim
   
   txt As
   
   Control
   
3. For
   
   Each
   
   txt In
   
   Me
   
   .
   
   Controls
   
4. If
   
   txt.
   
   GetType
   
   Is
   
   GetType
   
   (
   
   TextBox)
   
   Then
   
5. txt.
   
   Text
   
   =
   
   txt.
   
   Name
   
6. End
   
   If
   
7. Next
   
8. End
   
   Sub
   

Press F5 to run your project and click the Button to fire the code in the method.
