ASP.NET IDProperty
Control Standard Properties Reference
Definition and Usage
The ID property gets or sets the programming identifier assigned to the control.
This property is usually set and used when the current control interacts with other controls or scripts. Setting this property on the control provides programmatic access to the control's properties, events, and methods. Web developers can set this property by declaring the ID attribute in the opening tag of an ASP.NET control. If the property is not specified for the control (either declaratively or programmatically), a reference to the control can be obtained through the Controls property of its parent control.
Syntax
<asp:webcontrol id="id" runat="server" />
Example
The following example shows a Button control with the ID property set:
<form runat="server">
<asp:Button id="button" text="Submit" runat="server" />
</form>
<asp:Button id="button" text="Submit" runat="server" />
</form>
