Hi,

Try this Code in Button Click Event() Handler.

// open file dialog 

 OpenFileDialog open = new OpenFileDialog(); 

 // image filters

 open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp"; 

 if (open.ShowDialog() == DialogResult.OK)

{

  // display image in picture box

  pictureBox1.Image = new Bitmap(open.FileName);

  } 

Hi Aman,

is the only supported way for a browser to upload the file. Otherwise you have to write custom ActiveX controls ask the client browsers to install them. There are some third party controls which satisfy your requirement.

But you want to upload like Gmail, where there is no Upload button, no file upload control, you can hide those using css. Below is the link which explains the same.

Links for some of the third party controls.
