View 14 RepliesI am using VS2008. I have a table in which the jpg images are stored. I can retrieve the images from the table and display it in datagridview. But many images are of different sizes. So the cell height of the datagridview changes according to the image size. Is it possible to give a fixed cell size for the image column and also shrink the image to that cell height.

View 12 RepliesI have a datagridview bound to an Access datatable. It is nothing more than a one column list of chemicals. To allow the user to more easily navigate the list, if they press a letter it will jump to the first chemical alphabetically of that letter. If they keep tapping that same letter it will move down that list one by one. This all works fine. The problem is if you hold down the letter it will progress down the list but it doesn't show that progression. I want it to function much like if you hold down the down arrow key in a datable you'll see each successive cell be selected as it goes down the column.
