Hi As Quick Solution I have .dll File of Custom Picturebox Developed by Someone That Can have Scrollbars and Zomin Facility it can Zoom Image By Just Mouse Scroll Custom PictureBox.Dll Right Click in ToolBox of Visual Studio >> Choose Items then Select that Dll to use after that the Custom PictureBox Control Will be there in ToolBox after Implementing this You Dont Require those two Zoom+ and Zoom- Buttons PictureBox That Visual Studio Provide you is Limited to its Functionality if you want this scroll type of functionality you need to develop your own Control by Inheriting that PictureBoxClass Happy Coding :)

Kirtan Patel · Answer

this Error can be caused because you can have not selected the files you want to display so Program not found the string on index [0]

Maharaje · Answer

i have an error on this line: pictureBox1.ImageLocation = imageList[0]; this is the exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
