How are you storing the images? The basic idea is to have a FileUpload control so you can browse new image for update. You can then update the image from your database just like updating normal data in your database. The idea is to get the existing ID of the row that holds your image and then update it with the new image (either update the path or the image itself ~ that depends on how you store the images). Here's an example: private void StartUpLoad(){
//get the image file that was posted (binary format)
byte[] theImage = new byte[FileUpload1.PostedFile.ContentLength];
HttpPostedFile Image = FileUpload1.PostedFile;
Image.InputStream.Read(theImage, 0, (int)FileUpload1.PostedFile.ContentLength);
int length = theImage.Length; //get the length of the image
string fileName = FileUpload1.FileName.ToString(); //get the file name of the posted image
string type = FileUpload1.PostedFile.ContentType; //get the type of the posted image
int size = FileUpload1.PostedFile.ContentLength; //get the size in bytes that
if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "")
{
//Call the method to execute update in your database
Update(theImage, type, size, fileName, length);
Response.Write("Save Successfully!");
}
}
private void Update(int ID, string brand, decimal price, string description,byte[] image){
using (SqlConnection connection = new SqlConnection("YOUR CONNECTION STRING HERE")) {
string sql = "UPDATE YourTableName SET Brand = @Brand, Price = @Price, Description = @Description, Image = @Image WHERE ID = @ID";
using (SqlCommand cmd = new SqlCommand(sql, connection)) {
connection.Open();
cmd.Parameters.AddWithValue("@ID", ID);
cmd.Parameters.AddWithValue("@Brand", brand);
cmd.Parameters.AddWithValue("@Price", price);
cmd.Parameters.AddWithValue("@Description", description);
cmd.Parameters.AddWithValue("@Image", image);
cmd.ExecuteNonQuery();
}
}
}
protected void Button1_Click(object sender, EventArgs e){
StartUpLoad();
}
