I have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.
Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
means the images that will display in the picturebox is based on the value shown on the textbox (ProjID)..
Please see code below..

How to change a border color of ListView?
View 4 RepliesI'm trying to figure out how I can change a ListView's "Large ImageList" to another one at runtime. For example I have it attached to my Icons_64x64 ImageList right now but would want an option to switch it to Icons_128x128 at runtime. Hope that makes sense and someone has an idea out there. I haven't been able to come up with anything at all.
