ASPxClientTabControlBase.GetTab(index) Method

Returns a tab specified by its index.

Declaration

GetTab(
    index: number
): ASPxClientTab

Parameters

Name	Type	Description
index	number	The index of the tab object to retrieve.

Returns

Type	Description
ASPxClientTab	An ASPxClientTab object representing the tab located at the specified index within the control’s ASPxTabControl.Tabs collection.

Remarks

The tab control’s client-side functionality allows its tabs to be accessed programmatically on the client side. This method gets a client tab object specified by the index it has within the ASPxTabControl.Tabs collection.

Note that the index parameter is zero-based and its upper available value is specified by the ASPxClientTabControlBase.GetTabCount value decremented by one. If an invalid index is passed via the parameter, the method returns null.

This method can be used together with the ASPxClientTabControlBase.GetTabCount method when iterating through the tab control’s tab list.
