Bind Alphabetic range to DropDown List

Question

Hi 

 

I need to bind dropdown with A to Z (Can be vary) values. 

 

We can bind dropdown with numeric values like below,

 

int start = 0;

int count = 10 

ddlNumeric.DataSource= Enumerable.Range(start, count); 

 

Similarly looking for Alphabets where parameters can be configured.

 

Scenario #1 : 

 

Start = A 

End = Z 

ddlAlpha.DataSource = Should display  values from A to Z

 

 

Scenario #2:

Start = F

End = N 

ddlAlpha.DataSource= Should display values from F to N 

 

Start & end range should be configurable.

 

Appreciate  

 

Thanks
