Checkbox List in Dropdown

In this article we will see how to populate checkbox list in dropdown list.

Introduction: I am sure most of us have come across this requirement in our projects to select multiple items in dropdown list. I have created very lighter control with such features.

Copy the below code in your aspx page under body section. 

        <asp:TextBox ID="txtEmployee"  Text="Select Employee" runat="server" CssClass="textboxStyle" onclick="closepanel('block')">
</asp:TextBox> <asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" /> <asp:Label ID="lblselected" runat="server"></asp:Label> <asp:Panel ID="Pnldetails" runat="server" CssClass="Panelstyle" style="display:none"> <table width="100%"> <tr> <td> <asp:CheckBox ID="chkAll" runat="server" onclick="check(this)" Text="Select All" /> </td> <td align="right"> <img src="images/Close.png" alt="Close" title="Close" onclick="closepanel('none')" /> </td> </tr> </table> <asp:Panel ID="pnlchkbox" runat="server" ScrollBars="Vertical" Height="150px" Width="250px"> <asp:CheckBoxList ID="chklstEmployee" runat="server"> <asp:ListItem>David</asp:ListItem> <asp:ListItem>John</asp:ListItem> <asp:ListItem>Stephanie</asp:ListItem> <asp:ListItem>McDonald</asp:ListItem> <asp:ListItem>James</asp:ListItem> <asp:ListItem>Peter</asp:ListItem> <asp:ListItem>Williams</asp:ListItem> </asp:CheckBoxList> </asp:Panel> </asp:Panel>

Numeric Up Down:

Recently one of my friends asked me about the Numeric Up Down requirement.

Like we all know, I gave him suggestion to use the AjaxToolKit Numeric Uptown control.

Well that works fine. But his requirement was little bit different.

He wants user to select one of the values (15,30,45,60) using Numeric Uptown Control.

The AjaxToolKit Control will not support this functionality. Also I personally don’t like style of AjaxTookitControl  Number Updown Control.

AjaxToolkItControl reference: http://www.asp.net/AjaxLibrary/AjaxControlToolkitSampleSite/NumericUpDown/NumericUpDown.aspx


So I got an idea of creating Custom Control using Javascript:

In this article I will explain about the functionality of this control also I will share the source code.

Knockout is a JavaScript library that helps you to create rich, responsive display and editor user interfaces with a clean underlying data model. Knockout is called KO in short.
KO helps to build dynamic JavaScript UIs with MVVM and Asp.net

Observable property will automatically issue notifications whenever value changes. applyBindings used to apply the bindings. Copy the below code snippet to your page and check the output.
