Hi,
 
You can use range validator. Add range validator dynamically in code behind file in combobox selection change event.
 
In selection change event method Add below code.
 
if(selected range is 1-5)
{
RangeValidator1.ControlToValidate = "TextboxId";
RangeValidator1.MaximumValue = "Give Max what you want";
RangeValidator1.MinimumValue = " Assign min what you want";
}
else if(selected range is 6-12)
{
RangeValidator1.ControlToValidate = "TextboxId";
RangeValidator1.MaximumValue = "Give Max what you want";
RangeValidator1.MinimumValue = " Assign min what you want";
}
Hope this might help you.

Same you can check into button click event method and validate accordingly. If you are still not able to solve, Please put some code snippet.

here your combobox value is in the form of 1-5 6-10 11-20 so for this you need to add this value into an string. and then split that value in string and then you can convert that value into integer.
