DropDownList ddl_NMSMonths0 = (DropDownList)row.FindControl("lblNMSMonths");

The error is very clear.  You are trying to cast a label, lblNMSMonths, into a DropDown control.

Please take a few seconds to review your code before posting!

JafjitSingh, that's is not what the code - you wrote - is doing.   Your code is trying to convert a label to a dropdown.  

Use the selected value property of the dropdown list to set the selected value.  This syntax assumes you have a ddl_NMSMonths0 dropdown defined in the markup.

ddl_NMSMonths0.SelectedValue = ((Label)row.FindControl("lblNMSMonths")).Text;

I'm not sure how to help you.... Keep in mind that you regularly  ask the same questions and make the same mistakes. Maybe you should slow down and do a bit of learning.
