Enum Examples or How to Bind the DropDownList With Enum?

3 comments
Enum is the type provided by dotnet, it stores constant value in it. When we want to specify some constant value to use in the project then it is very usefull for readability.

In this post I will show you how to declare an enum and how to use it in the program.
Here I have bind the enum to the dropdown list

Declare the enum as below

public enum Days { Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday }

In aspx page I have added DropDownList named ddlDays as below

 <asp:DropDownList ID="ddlDays" runat="server">
        </asp:DropDownList>

Now below is the code to bind dropdownlist control with above enum
// Add first item to the drop down list to select lable
        ddlDays.Items.Add("--Select Days--");

        string[] enumNames = Enum.GetNames(typeof(Days));
        foreach (string item in enumNames)
        {
            int value = (int)Enum.Parse(typeof(Days), item);
            ListItem listItem = new ListItem(item, value.ToString());
            //Add one by one item to the drop down list
            ddlDays.Items.Add(listItem);
        }

Change cursor to hand on mouseover using jQuery

4 comments
When ever we need to change the mouse cursor using JQuery then we can do it very easily.

In my today's post I will show you how can we change the mouse cursor to the Hand type cursor while user hover mouse on the particular element.
It is very simple just look at the below JQuery code.
   




$(document).ready(function() {
  $("#elementid").hover(function() {
    $(this).css("cursor", "hand");
  });
});

In above code 'elementid' is the name of the element on which you want a mouse pointer as a hand while hovering a mouse over it.

Happy Coding...
