UserControl.Cache Property

Gets the Cache object that is associated with the application that contains the user control.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

[BrowsableAttribute(false)]
public Cache Cache { get; }

Property Value

Type: System.Web.Caching.Cache
The Cache object in which to store the user control's data.

The Cache allows you to store data for later retrieval, and is shared across the application. The data that you store is independent of the current page or user session. Access data through this property to boost page or application performance if creating the data is slow. For more information about using the Cache, see Caching Application Data.

The following example uses the Cache property to store the Text property value of a Label Web server control, txtValue, in the Cache object associated with the user control's application. It uses the Cache property to do so, assigning the item a key parameter value of txtName.Text.

Security noteSecurity Note

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview.

private void cmdAdd_Click(Object objSender, EventArgs objArgs)
{
    if (txtName.Text != "")
    {
        // Add this item to the cache.
        Cache[txtName.Text] = txtValue.Text;
    }
}
