[asp.net] SelectedValue vs SelectedItem.Value of DropDownList

I'm working on an old project written and then patched by several people over the years. At some places they have used SelectedValue property and other places they used SelectedItem.Value.

Question: Is SelectedValue just a syntactic sugar for SelectedItem.Value or SelectedValue works differently under the hood? Which one performs better?

Edit: SelectedItem.Text was replaced with SelectedItem.Value

One important distinction between the two (which is visible in the Reflected code) is that SelectedValue will return an empty string if a nothing is selected, whereas SelectedItem.Value will throw a NullReference exception.

They are both different. SelectedValue property gives you the actual value of the item in selection whereas SelectedItem.Text gives you the display text. For example: you drop down may have an itme like

<asp:ListItem Text="German" Value="de"></asp:ListItem>

So, in this case SelectedValue would be de and SelectedItem.Text would give 'German'

EDIT:

In that case, they aare both same ... Cause SelectedValue will give you the value stored for current selected item in your dropdown and SelectedItem.Value will be Value of the currently selected item.

So they both would give you the same result.

In droupDown list there are two item add property.

1) Text 2) value

If you want to get text property then u use selecteditem.text

and If you want to select value property then use selectedvalue property

In your case i thing both value and text property are the same so no matter if u use selectedvalue or selecteditem.text

If both are different then they give us different results

Be careful using SelectedItem.Text... If there is no item selected, then SelectedItem will be null and SelectedItem.Text will generate a null-value exception.

.NET should have provided a SelectedText property like the SelectedValue property that returns String.Empty when there is no selected item.
