Hello,
Here is your complete code:
Server side(.cs file):

protected void Button1_Click(object sender, EventArgs e)
{
if (FileUpload1.PostedFile != null && FileUpload1.PostedFile.FileName != "")
{

byte[] myimage = new byte[FileUpload1.PostedFile.ContentLength];

HttpPostedFile Image = FileUpload1.PostedFile;

Image.InputStream.Read(myimage, 0,
(int)FileUpload1.PostedFile.ContentLength);



SqlConnection myConnection =
new SqlConnection("Data Source =RASHED-PC;Initial Catalog= TestDB; Integrated Security= true");


SqlCommand storeimage =
new SqlCommand("INSERT INTO Iamge_Gallery "
+ "(Img_Id, Image_Content, Image_Type, Image_Size) "
+ " values (4, @image, @imagetype, @imagesize)"
, myConnection);


storeimage.Parameters.Add("@image",
SqlDbType.Image, myimage.Length).Value = myimage;

storeimage.Parameters.Add("@imagetype", SqlDbType.VarChar, 100).Value
= FileUpload1.PostedFile.ContentType;

storeimage.Parameters.Add("@imagesize", SqlDbType.BigInt, 99999).Value
= FileUpload1.PostedFile.ContentLength;

myConnection.Open();
storeimage.ExecuteNonQuery();
myConnection.Close();

Response.Write("successfully upload the image");
GetImageFromDB();
}
}
private void GetImageFromDB()
{
byte[] myimage = new byte[FileUpload1.PostedFile.ContentLength];
HttpPostedFile Image = FileUpload1.PostedFile;
Image.InputStream.Read(myimage, 0,
(int)FileUpload1.PostedFile.ContentLength);
string connStrName="Data Source =RASHED-PC;Initial Catalog= TestDB; Integrated Security= true";
string storeimage ="SELECT [Img_Id],[Image_Content],[Image_Type],[Image_Size]FROM [TestDB].[dbo].[Iamge_Gallery]";
DataTable dt = new DataTable();

}

if (dt.Rows.Count>0)
{
BindApplicantImage((byte[])dt.Rows[0]["Image_Content"]);
}

Response.Write("successfully upload the image");

}

{
