Hi,
Please try with the following code:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Inserting images into databse and displaying images with gridview</title>
<style type="text/css">
.Gridview
{
font-family:Verdana;
font-size:10pt;
font-weight:normal;
color:black;
width:500px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<table>
<tr>
<td>
Image Name:
</td>
<td>
<asp:TextBox ID="txtImageName" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td>
Upload Image:
</td>
<td>
<asp:FileUpload ID="fileuploadImage" runat="server" />
</td>
</tr>
<tr>
<td>
</td>
<td>
<asp:Button ID="btnUpload" runat="server" Text="Upload" onclick="btnUpload_Click" />
</td>
</tr>
</table>
</div>
<div>
<asp:GridView ID="gvImages" CssClass="Gridview" runat="server" AutoGenerateColumns="False"
HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="white">
<Columns>
<asp:BoundField HeaderText = "Image Name" DataField="imagename" />
<asp:TemplateField HeaderText="Image">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ImageHandler.ashx?ImID="+ Eval("ImageID") %>' Height="150px" Width="150px"/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>
After that add using System.IO; using System.Data.SqlClient; and using System.Configuration; namespaces and write the following code in code behind
string strcon = ConfigurationManager.ConnectionStrings["dbconnection"].ConnectionString;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridData();
}
}
/// <summary>
/// btnUpload_Click event is used to upload images into database
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnUpload_Click(object sender, EventArgs e)
{
//Condition to check if the file uploaded or not
if (fileuploadImage.HasFile)
{
//getting length of uploaded file
int length = fileuploadImage.PostedFile.ContentLength;
//create a byte array to store the binary image data
byte[] imgbyte = new byte[length];
//store the currently selected file in memeory
HttpPostedFile img = fileuploadImage.PostedFile;
//set the binary data
img.InputStream.Read(imgbyte, 0, length);
string imagename = txtImageName.Text;
//use the web.config to store the connection string
SqlConnection connection = new SqlConnection(strcon);
connection.Open();
SqlCommand cmd = new SqlCommand("INSERT INTO Image (ImageName,Image) VALUES (@imagename,@imagedata)", connection);
cmd.Parameters.Add("@imagename", SqlDbType.VarChar, 50).Value = imagename;
cmd.Parameters.Add("@imagedata", SqlDbType.Image).Value = imgbyte;
int count = cmd.ExecuteNonQuery();
connection.Close();
if (count == 1)
{
BindGridData();
txtImageName.Text = string.Empty;
ScriptManager.RegisterStartupScript(this, this.GetType(), "alertmessage", "javascript:alert('" + imagename + " image inserted successfully')", true);
}
}
}
/// <summary>
/// function is used to bind gridview
/// </summary>
private void BindGridData()
{
SqlConnection connection = new SqlConnection(strcon);
SqlCommand command = new SqlCommand("SELECT imagename,ImageID from [Image]", connection);
SqlDataAdapter daimages = new SqlDataAdapter(command);
DataTable dt = new DataTable();
daimages.Fill(dt);
gvImages.DataSource = dt;
gvImages.DataBind();
gvImages.Attributes.Add("bordercolor", "black");
}
