Collection<T>.Find(Predicate<T>) Method
Returns the first element that matches the conditions defined by the specified predicate.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v20.2.dll
NuGet Package: DevExpress.Web
Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| match | Predicate<T> | A delegate that defines the conditions of the elements to search for. |
Returns
| Type | Description |
|---|---|
| T | The element that matches the conditions defined by the predicate. |
Remarks
The Find method individually passes elements of the current collection to a predicate, and returns the first element that matches the predicate. A predicate is a delegate to a method that returns true if the object passed to it matches the conditions defined in the delegate; otherwise the method returns false.
Example
The code sample below demonstrates how to obtain a navigation bar group that is currently expanded. For this purpose, the Find method is used. The IsExpanded predicate determines whether a group is expanded.
using DevExpress.Web.ASPxNavBar;
...
NavBarGroup ExpandedGroup = ASPxNavBar1.Groups.Find(IsExpanded);
...
private static bool IsExpanded(NavBarGroup group) {
return group.Expanded;
}
