Adding items to DropDown list

Question

See more:

When I add an item from .aspx.cs page, I got three ways to do it as following

ddlCalanderName.Items.Insert(0, new ListItem("Item1" , "0"));
ddlCalanderName.Items.Insert(0, new ListItem("Item1"));
ddlCalanderName.Items.Insert(0, "Item1");

It gives me same output

Can any one tell me what is the diffrence betwween these three?

Thanks

Solution 1

It's called method overloading, and you're using both of the overloads for the Insert method.

The only one that does something different is the first one. It sets the text (the way it appears visually to the user in the list) and the value of the item (two different things), where the other two just set the text.
