How to insert certain numbers in a Text boxes ?

Abdalla,

Here is the approach to achieve what you are looking for. In the User form you need to have the fixed value before the actual input textbox as shown below. Then while getting the value in the code behind (Coding) you need to concatenate (combine) two values "TransLabel1" + "TransNumber1" this will give you "1111...........".

Please let me know if you need further details.
