In this article we will learn how to Bind Chekbox List and get the Selected Items from List. We will make a Web application using C#. Let’s start.

  1. Open Visual Studio. Select New Web Site.



  2. Name it as you want. My application's name is CheckBoxList_Example.


  3. First Of All Add Web Form. Go to Solution Explorer > Right Click on the Web Site > Select Add > Add New Item > Select > Web Form and Give the Web Form Name, My We Form Page Name Is CheckList_Page.


  4. Add Check Box List , Label and Button On CheckList_Page.aspx Page.
    1. <asp:CheckBoxList ID="CheckboxList1" runat="server" AutoPostBack="false" Width="450px">
    2. </asp:CheckBoxList>
    4. <asp:Label ID="lblmsg" class="textcls" runat="server"></asp:Label>
    6. <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Show Data" />
  5. Create a method for Bind the CheckBox List.
    1. protected void Bind_CheckList() // Method for Binding The Checkbox List
    2. {
    3. List<string> listContents = new List<string>();// Create a List of String Elements
    4. listContents.Add("DehraDun");
    5. listContents.Add("Shimla");
    6. listContents.Add("Patna");
    7. listContents.Add("Mumbai");
    8. listContents.Add("Delhi");
    9. listContents.Add("Goa");
    10. listContents.Add("Chennai");
    11. listContents.Add("Noida");
    12. listContents.Add("GuruGram");
    14. CheckboxList1.DataSource = listContents;//Set Datasource to CheckBox List
    15. CheckboxList1.DataBind(); // Bind the checkboxList with String List.
    17. }
  6. Call this Method On PageLoad.
    1. protected void Page_Load(object sender, EventArgs e)
    2. {
    3. if (Page.IsPostBack == false)
    4. {
    5. Bind_CheckList();// Call CheckBox List Bind Method.
    6. }
    7. }
  7. Get the selected Item List From CheckBoxList Items and show Selected Items List with Help of Label .
    1. protected void Button1_Click(object sender, EventArgs e)
    2. {
    3. string str = "";
    5. for(int i=0;i<CheckboxList1.Items.Count ;i++)
    6. {
    7. if(CheckboxList1.Items[i].Selected==true)// getting selected value from CheckBox List
    8. {
    9. str += CheckboxList1.Items[i].Text + " ," + "<br/>" ; // add selected Item text to the String .
    10. }
    13. }
    14. if(str!="")
    15. {
    16. str = str.Substring(0, str.Length - 7); // Remove Last "," from the string .
    17. lblmsg.Text = "Selected Cities are <br/><br/>" + str; // Show selected Item List by Label.
    18. }
    19. }

I hope this is helpful for developing. Thanks.
