Actually my problem is I have some screens on Asp.net by using Ajax. In these screen I am using some drop downs and data grid. On page load data is populated on dropdowns by default and on run button click data is populated on data grid based on selected value from drop down. First time when I open any screen everything is working properly but next time its not loaded data on run button click, for this I have to refresh page and then the screen working.

Hi,

Documents can be of any type(work,excel,pdf etc even image files can be uploaded).Now my doubt is how to achieve the dowlaoding of the files that are stored. I am working on .net 2.0

The person who answered you here has given you all the important information ( that is, how to use the response object to write a file back out for download ). In fact, what you want is simpler, you just need to read the file bytes from the file system.

This has nothing to do with ASP.NET, it's a javascript problem. I think it's nasty, but here:

{
int imageHeight = 0;
int imageWidth = 0;
System.Drawing.Image fullSizeImg;
double scaleFactor = 1;
//image.Save(Response.OutputStream, ImageFormat.Jpeg);
fullSizeImg = image;
if ((fullSizeImg.Width > maxWidth) || (fullSizeImg.Height > maxHeight))
{
int deltaWidth = fullSizeImg.Width - maxWidth;
int deltaHeight = fullSizeImg.Height - maxHeight;
if (deltaHeight > deltaWidth)
{
scaleFactor = Convert.ToDouble(maxHeight) / fullSizeImg.Height;
}
else
{
scaleFactor = Convert.ToDouble(maxWidth) / fullSizeImg.Width;
}
}
imageWidth = Convert.ToInt32(fullSizeImg.Width * scaleFactor);
imageHeight = Convert.ToInt32(fullSizeImg.Height * scaleFactor);
Bitmap bitmapImg = new Bitmap(imageWidth, imageHeight, fullSizeImg.PixelFormat);
Response.ContentType = "image/Jpeg";
Response.ContentType = "image/Bmp";
Response.ContentType = "image/Gif";
bitmapImg.Save(Response.OutputStream, ImageFormat.Jpeg);
bitmapImg.Save(Response.OutputStream, ImageFormat.Bmp);
bitmapImg.Save(Response.OutputStream, ImageFormat.Gif);
Graphics new_g = Graphics.FromImage(bitmapImg);

Basically, you replace the word private on the classes you're creating, with public.
This question also has nothing to do with ASP.NET. It's also straightforward enough that I'd be recommending you buy a beginners book and work through it.
