Use length block from text part

When text box text changed, 
If the length text box text is greater than or equal to {enter number}
Then add your logic 
Else {this part is the length is not reached the desired amount}

See by this way user can enter only lenth of 5 texts in textbox1 (includs number, texts, space, …)

If it crosses that lenth then keyboard will hide
