Telerik.Web.UI.RadTabStrip

Remarks

The RadTabStripcontrol is used to display a list of tabs in a Web Forms page and is often used in combination with a Telerik.Web.UI.RadMultiPage RadMultiPagecontrol for building tabbed interfaces. The RadTabStripcontrol supports the following features: bullet Databinding that allows the control to be populated from various datasourcesProgrammatic access to the RadTabStripobject model which allows to dynamic creation of tabstrips, populate h tabs, set properties.Customizable appearance through built-in or user-defined skins.TabsThe RadTabStripcontrol is made up of tree of tabs represented by Telerik.Web.UI.RadTab RadTabobjects. Tabs at the top level (level 0) are called root tabs. A tab that has a parent tab is called a child tab. All root tabs are stored in the P:Telerik.Web.UI.RadTabStrip.Tabs Tabscollection. Child tabs are stored in a parent tab's P:Telerik.Web.UI.RadTab.Tabs Tabscollection. Each tab has a P:Telerik.Web.UI.RadTab.Text Textand a P:Telerik.Web.UI.RadTab.Value Valueproperty. The value of the P:Telerik.Web.UI.RadTab.Text Textproperty is displayed in the RadTabStripcontrol, while the P:Telerik.Web.UI.RadTab.Value Valueproperty is used to store any additional data about the tab, such as data passed to the postback event associated with the tab. When clicked, a tab can navigate to another Web page indicated by the P:Telerik.Web.UI.RadTab.NavigateUrl NavigateUrlproperty. You can find information on the Server-side API of RadTabStrip at https://docs.telerik.com/devtools/aspnet-ajax/controls/tabstrip/server-side-programming/events .

AppendDataBoundItems Boolean

Gets or sets a value that indicates whether child tabs are cleared before data binding.

Remarks

The AppendDataBoundTabs property allows you to add items to the RadTabStrp control before data binding occurs. After data binding, the items collection contains both the items from the data source and the previously added items.The value of this property is stored in view state.

CausesValidation Boolean

Gets or sets a value indicating whether validation is performed when a tab within the RadTabStrip control is selected.

Remarks

By default, page validation is performed when a tab is selected.

You can specify or determine whether validation is performed on both the client and the server when a tab is clicked by using the CausesValidation property. To prevent validation from being performed, set the CausesValidation property to false.

                    The value of the column specified by DataFieldParentID must be null (Nothing) for root tabs. This is a requirement
                    for databinding RadTabStrip.

DataNavigateUrlField String

Gets or sets the field of the data source that provides the URL to which tabs navigate.

Remarks

Use the DataNavigateUrlField property to specify the field of the data source (in most cases the name of the database column) which provides the values for the NavigateUrl property of databound tabs.

DataTextFormatString String

Gets or sets the formatting string used to control how text to the tabstrip control is displayed.

Remarks

Use the DataTextFormatString property to provide a custom display format for text of the tabs. The data format string consists of two parts, separated by a colon, in the form { A: Bxx }. For example, the formatting string {0:F2} would display a fixed point number with two decimal places.

                   The entire string must be enclosed in braces to indicate that it is a format string and not a literal string.
                   Any text outside the braces is displayed as literal text.

                   The value before the colon (A in the general example) specifies the parameter index in a zero-based list of parameters.
