Remove try-catch from Button1/2_Click event handlers

Refactored Button1_Click and Button2_Click to eliminate local try-catch blocks, allowing exceptions to propagate. Cleaned up redundant code and improved clarity by moving variable declarations outside of the previous try blocks. Core logic remains unchanged.
