| DesignMode | This property returns true to indicate that the control is being used in the context of a designer. Software developer’s custom controls can use this property when design-time behavior is different than run-time behavior. | 2.0, 3.0, 3.5, 4.0 |
| Enabled | Software developer should set this property to true when he/she wants to specify or determine whether a control is functional. When developer sets to false, the control appears dimmed, preventing any input from being entered in the control. Notes:
|
1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| EnableTheming | This property overrides Control. EnableTheming.
The property indicates whether themes are enabled for a specified control. When the property’s value is true, the application’s theme directory is searched for control skins to apply.

2.0, 3.0, 3.5, 4.0 |
| EnableViewState | Software developer must enable view state for the server control setting its value to true if he/she wants to maintain its state across HTTP requests. Sometimes is better to set value of this property to false if for example Web application is loading a database request into a server control. In this case application performance will be improved. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| Events | This read-only property returns a list of event handler delegates for the control.

| HasChildViewState | Software developer can use this property to verify that any child controls of the server control are storing view-state information. Using it in this way he/she can avoid unnecessary calls to the ClearChildViewState method. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| Height | This property is used to specify the height of the Web server control. When software developer sets this property he/she should use combination of a numeric value followed by type of measurement: px (for pixels) or % (for percentage) and so on.This property does not render for all controls in browsers earlier than Microsoft Internet Explorer version 4. Controls that do not render this property in earlier browsers include Label, HyperLink, LinkButton, and any validation controls. The CheckBoxList, RadioButtonList and DataList also do not render this property in earlier browsers when their RepeatLayout property is set to RepeatLayout.Flow. Furthermore, only unit types of Pixel and Percentage are supported in earlier browsers. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| ID | Web developers can set this property by declaring ID attribute in the opening tag of an ASP.NET server control. Another possible way to set it is programmatically. If this property is not specified for a server control, either declaratively or programmatically, Web developer can obtain a reference to the control through its parent control’s Controls property. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| IdSeparator | Software developer can’t use this property directly from his/her code, because it supports the .NET Framework infrastructure. The character contained in this property ( by default $ ) is used to separate the control identifiers for child controls. The ID separator character is appended to the ID property. | 2.0, 3.0, 3.5, 4.0 |
| IsChildControlStateCleared | This property has value true if children of this control do not use control state; otherwise, false. | 2.0, 3.0, 3.5, 4.0 |
| IsEnabled | This property returns true if the Enabled property is true for this control and any containing controls. | 2.0, 3.0, 3.5, 4.0 |
| IsTrackingViewState | This property returns value true if the control is marked to save changes to its view state; otherwise, false.
|
1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| IsViewStateEnabled | This property returns value true if view state is enabled for the control; otherwise false. View state can be enabled at the page, container, or control level. When view state is disabled at the page or container level, view state is disabled for all controls contained by the page or container. The property indicates whether view state is enabled by pages, containers, or controls. In some cases it is possible values for the EnableViewState property and the IsViewStateEnabled property to be different. For example, if the Page containing the control has view state disabled, the EnableViewState property can be true while the IsViewStateEnabled property is false. Notes: Developers will set the EnableViewState property to indicate whether they are using view state with your control. Web developers can use this property in their code to determine whether view state is enabled for their control and all containers. | 2.0, 3.0, 3.5, 4.0 |
| LoadViewStateByID | This property returns value true if the control loads its view state by ID; otherwise, false. Its default value is false. | 2.0, 3.0, 3.5, 4.0 |
| NamingContainer | Using this property software developer can get a reference to the server control’s naming container, which creates a unique namespace for differentiating between server controls with the same Control.ID property value. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| Page | Provides a reference to the web page that contains this control as a System.Web.UI.Page object. This property’s value reflects the name of the .aspx file that contains the server control. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| Parent | This property provides a reference to the control that contains this control. If the control is placed on the page directly (rather than inside another control), it will return a reference to the page object. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| Site | Using this property software developer can get information about the container that hosts the current control when rendered on a design surface. A site binds a Component object to a Container object and enables communication between the two. It also provides a way for the container to manage its components. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| SkinID | This property overrides Control.SkinID.
Web developer can get or set the skin to apply to the control. Skins available to a control are contained in one or more skin files in a theme directory. The SkinID property specifies which of these skins to apply to the control. A skin is specific to a particular control i.e. software developer cannot share skin setting between controls of different types. If developer does not set the SkinID property, a control uses the default skin if one is defined. |
2.0, 3.0, 3.5, 4.0 |
| Style | Web developer can use this property to get a collection of text attributes that will be rendered as a style attribute on the outer tag of the Web server control. This property will render on all browsers for all controls. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| TabIndex | With this number software developer can control the tab order. The control with a TabIndex of zero has the focus when the page first loads.

| UniqueID | This property can be used to get the unique, hierarchically qualified identifier for the server control. This property differs from the ID property, in that the UniqueID property includes the identifier for the server control’s naming container. This identifier is generated automatically when a page request is processed. This property is particularly important in differentiating server controls contained within a data-binding server control that repeats as Repeater, DataList, DetailsView, FormView, and GridView Web server controls. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
| ViewState | Web developers can use this property to get a dictionary of state information that allows them to save and restore the view state of a server control across multiple requests for the same page. | 1.0,1.1, 2.0, 3.0, 3.5, 4.0 |
