Dear All Master,


I want to resize the dimensions of the image so that it helps the performance of the image that appears in the columnuboudcolumn image in the gridview. Is there any solution?
because if I use directly from the size of the image file it makes it slow in the gridview.
for image file information there are 5000 files with each file having dimensions of 1748x2480
thanks
