Page.IsPostBack Property in Asp.Net



Here we will discuss about the Page.IsPostBack Property in Asp.Net.

- Gets a value that indicates whether the page is being rendered for the first time or is being loaded in response to a postback.

- The IsPostBack property can be used to determine if the page is submitted to itself. When a form is submitted back to the same page that contains it, it's called a post back. ASP.NET provides a property called IsPostBack that is TRUE when the page is being loaded as a result of a post back, and is FALSE otherwise.

- Below is the way to use IsPostBack property

C#.Net Syntax:
private void Page_Load()
{
    if (!IsPostBack)
    {
        //You can write here the code, which you want to execute in the first time when the page is loaded.
        FunctionToBindSomething();
    }
}

VB.Net Syntax:
Sub Page_Load
         IF Not IsPostBack THEN
                    ' You can write here the code, which you want to execute in the first time when the page is loaded.
        FunctionToBindSomething();
          END IF
End Sub
