So if you press a key on the keyboard,where is the selection to which textbox it should be writing?

You have multiple text boxes. If I type on the keyboard, how to know which textbox to send the text to, of all the boxes you have got?

Are you saying that you want to select any one of many TextBoxes to type in, and you want all TextBoxes to display what you type in the selected TextBox ?

If you (unlikely) need to update all the textboxes with the same button then list all of them in your handler, e.g

C#

...
Search_Form.tb.Text += b.Text;
Search_Form.tb1.Text += b.Text; 
...

On the other hand, if you need to update just the 'currently selected' textbox then you should implement a mechanism for identifying it. For instance you might assign to the curSelTextBox variable a reference to the last text box that got the input focus. Then, in your event handler use:

C#

...
curSelTextBox.Text += b.Text;
