Bind Image With Repeater And Change Image On Click

This article shows you how to bind data in Repeater controls without using any database in ASP.NET. Also, we will learn here how to bind controls with data without using a database. Additionally, how to handle repeater common events will be discussed. For this I have shownthe clicked-on image and changed image on click.

Initial Chamber

Step 1: Open Visual Studio and create an empty website, then provide a suitable name such as RepeaterChangeImage.

Step 2: In Solution Explorer you will get your empty website, then add some web forms.

RepeaterChangeImage (your empty website). Right-click and select Add New Item Web Form. Name it RepeaterChangeImage.aspx.

Design Chamber

Step 3:

Open the RepeaterChangeImage.aspx file and write some code for the design of the application. Choose control from toolbox and put on your design page as in the following code snippet:

  1. <div>  
  2. <asp:RepeaterID="Repeater1"runat="server">  
  3. <ItemTemplate>  
  4. <asp:LabelID="Label1"runat="server"><%#Eval("Product_Name")%></asp:Label>  
  5. <asp:LabelID="Label2"runat="server"><%#Eval("Quantity")%></asp:Label>  
  6. <asp:LabelID="Label3"runat="server"><%#Eval("Price")%></asp:Label>  
  7. <asp:ImageButtonID="ImageButton1"runat="server"Height="50px"Width="100px"ImageUrl='<%#Eval("path") %>'  
  8. CommandArgument='<%#Eval("path")%>'OnClick="ImageButton1_Click"/><br/>  
  9. </ItemTemplate>  
  10. </asp:Repeater>  
  11. </div> 
Design of page looks like the following:

page

Here, I've designed the GridView Control and uploader used some property as in the following code snippet:
  1. <%@PageLanguage="C#"AutoEventWireup="true"EnableEventValidation="true"CodeFile="ChangeImageRepeater.aspx.cs"Inherits="ChangeImageRepeater"%>  
  2.   
  3. <!DOCTYPEhtml>  
  4.   
  5. <htmlxmlns="http://www.w3.org/1999/xhtml">  
  6. <headrunat="server">  
  7. <title></title>  
  8. </head>  
  9. <body>  
  10. <formid="form1"runat="server">  
  11. <div>  
  12. <asp:RepeaterID="Repeater1"runat="server">  
  13. <ItemTemplate>  
  14. <asp:LabelID="Label1"runat="server"><%#Eval("Product_Name")%></asp:Label>  
  15. <asp:LabelID="Label2"runat="server"><%#Eval("Quantity")%></asp:Label>  
  16. <asp:LabelID="Label3"runat="server"><%#Eval("Price")%></asp:Label>  
  17. <asp:ImageButtonID="ImageButton1"runat="server"Height="50px"Width="100px"ImageUrl='<%#Eval("path") %>'  
  18. CommandArgument='<%#Eval("path")%>'OnClick="ImageButton1_Click"/><br/>  
  19. </ItemTemplate>  
  20. </asp:Repeater>  
  21. </div>  
  22. </form>  
  23. </body>  
  24. </html>  
CODE CHAMBER

Step 4:

In the code chamber we will write some code so that our application works. Adding the following namespaces under namespace section of your code behind page.
  1. using System;  
  2. usingSystem.Collections.Generic;  
  3. usingSystem.Linq;  
  4. usingSystem.Web;  
  5. usingSystem.Web.UI;  
  6. usingSystem.Web.UI.WebControls;  
  7. usingSystem.Data;  
  8. usingSystem.Data.SqlClient;  
  9. usingSystem.Configuration;  
Code behind Page
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.Linq;  
  4. using System.Web;  
  5. using System.Web.UI;  
  6. using System.Web.UI.WebControls;  
  7. using System.Data;  
  8. using System.Data.SqlClient;  
  9. using System.Configuration;  
  10.   
  11. public partial classChangeImageRepeater: System.Web.UI.Page  
  12. {  
  13.     protected void Page_Load(object sender, EventArgs e)  
  14.     {  
  15.         if (!IsPostBack)   
  16.         {  
  17.   
  18.             BindRepeater();  
  19.         }  
  20.     }  
  21.   
  22.     protected void BindRepeater()  
  23.     {  
  24.         DataSet ds = newDataSet();  
  25.         DataTabledt;  
  26.         DataRowdr;  
  27.         DataColumnpName;  
  28.         DataColumnpQty;  
  29.         DataColumnpPrice;  
  30.         DataColumnpPath;  
  31.         //int i = 0;  
  32.         dt = newDataTable();  
  33.         pName = newDataColumn("Product_Name", Type.GetType("System.String"));  
  34.         pQty = newDataColumn("Quantity", Type.GetType("System.Int32"));  
  35.         pPrice = newDataColumn("Price", Type.GetType("System.Int32"));  
  36.         pPath = newDataColumn("path", Type.GetType("System.String"));  
  37.         dt.Columns.Add(pName);  
  38.         dt.Columns.Add(pQty);  
  39.         dt.Columns.Add(pPrice);  
  40.         dt.Columns.Add(pPath);  
  41.         dr = dt.NewRow();  
  42.   
  43.         dr["Product_Name"] = "Product 1";  
  44.         dr["Quantity"] = 2;  
  45.         dr["Price"] = 200;  
  46.         dr["path"] = "image/Produc1.jpeg";  
  47.         dt.Rows.Add(dr);  
  48.   
  49.         dr = dt.NewRow();  
  50.         dr["Product_Name"] = "Product 2";  
  51.         dr["Quantity"] = 5;  
  52.         dr["Price"] = 480;

  54.   
  55.         dt.Rows.Add(dr);  
  56.         dr = dt.NewRow();  
  57.         dr["Product_Name"] = "Product 3";  
  58.         dr["Quantity"] = 8;  
  59.         dr["Price"] = 100;  
  60.         dr["path"] = "image/Produc3.jpeg";  
  61.         dt.Rows.Add(dr);  
  62.   
  63.         dr = dt.NewRow();  
  64.         dr["Product_Name"] = "Product 4";  
  65.         dr["Quantity"] = 2;  
  66.         dr["Price"] = 500;  
  67.         dr["path"] = "image/Produc4.jpeg";  
  68.         dt.Rows.Add(dr);  
  69.   
  70.         ds.Tables.Add(dt);  
  71.         Repeater1.DataSource = ds.Tables[0];  
  72.         Repeater1.DataBind();  
  73.     }  
  74.     protected void ImageButton1_Click(object sender, ImageClickEventArgs e)  
  75.     {  
  76.         ImageButtonImgBtn = (ImageButton) sender;  
  77.         string path = ((ImageButton) sender).CommandArgument;  
  78.         if (ImgBtn.ImageUrl == path)  
  79.         {  
  80.             ImgBtn.ImageUrl = "image/Penguins.jpg";  
  81.             ImgBtn.BackColor = System.Drawing.Color.Aqua;  
  82.         } else   
  83.         {  
  84.             ImgBtn.ImageUrl = path;  
  85.             ImgBtn.BackColor = System.Drawing.Color.Red;  
  86.         }  
  87.     }  
  88. }  
Output

First Loading:

After click on Image:
