Set default value to text box from lookup field when add new

I have a form with a look-up field and text fields. I want to set default values to text fields basing on what value of lookup field selected (take values from lookup table).
Please let me know how to do that.


Maybe you can use Change event of the DropDown to set desired default values to the TextBoxes.

I am still stuck how to get an object from Enumerable<>.


Have you tried Change event of the DropDown?

I tried, I need to invoke a method.

Thank you very much.


Do you want cascading DropDowns like this demo?

Thank you Enchev,

I solved my problem.
