The EnableViewState property of controls in ASP.Net

The EnableViewState property is a property of controls in ASP.Net that specifies whether to enable view state for the control.

The view state is a mechanism used to store control state during postbacks, keeping the values of controls’ properties unchanged between postbacks. During a postback, the control’s property values are saved in a hidden field and restored when the page loads.

The EnableViewState property can have two possible values:

1. True: Indicates the enablement of view state. The property values of the control will remain unchanged between page postbacks, with a default value of True.
2. False: Indicates disabled view state. The control’s property value will not be saved in a hidden field and will be reloaded each time the page is posted back. Default is False.

By setting the EnableViewState property, you can control whether a control maintains its state and how it restores that state during page postbacks. Disabling view state can improve performance in some cases by reducing the amount of data that needs to be transmitted during page postbacks. However, disabling view state can also cause controls to lose their state between page postbacks.

You can enable or disable view state by setting the EnableViewState property of a control in the ASP.Net page’s control tag or in the code. For example:

<asp:TextBox ID="TextBox1" runat="server" EnableViewState="true"></asp:TextBox>

Or

TextBox1.EnableViewState = true;
