Wisej.Web.ListControlConvertEventHandler
Wisej.Web.ListControl
Namespace: Wisej.Web
Assembly: Wisej.Framework (4.0.0.0)
Provides a common implementation of members for the ListBox and ComboBox classes.
Boolean: Returns or sets a value indicating that the control can display HTML in the Text property. (Default: False)
Boolean: Returns a value indicating whether the list enables selection of list items.
BorderStyle: Returns or sets the type of border that is drawn around the ListControl. (Default: Solid)
CurrencyManager: Returns the CurrencyManager associated with this control.
Object: Returns or sets the data source for this ListControl. (Default: null)
Throws:
ArgumentException The assigned value does not implement the IList or IListSource interfaces.
String: Returns or sets the property to display for this ListControl. (Default: "")
IFormatProvider: Returns or sets the IFormatProvider that provides custom formatting behavior. (Default: null)
String: Returns or sets the format-specifier characters that indicate how a value is to be displayed. (Default: "")
Boolean: Returns or sets whether formatting is applied to the DisplayMember property of the ListControl. (Default: False)
String: Returns or sets the property to use as the icon for the items in the ListControl. (Default: "")
Boolean: Returns or sets a value that indicates that the control is invalid.
String: Returns or sets the invalid message that is shown in the invalid tooltip. (Default: "")
Boolean: Returns or sets a value that indicates that the control has been modified by the user since the control was created or its contents were last set.
Int32: Returns or sets the number of items to prefetch outside of the visible area when VirtualScroll is set to true. The default is 0 (disabled). (Default: 0)
Int32: When overridden in a derived class, gets or sets the zero-based index of the currently selected item.
Object: Returns or sets the value of the member property specified by the ValueMember property. (Default: null)
Throws:
InvalidOperationException The assigned value is null or the empty string ("").
Boolean: Returns or sets whether to show tooltips (set using ToolTipMember) for the list items. (Default: False)
String: Returns or sets the property to use as the tooltip for the items in the ListControl, when the property ShowToolTips is set to true. (Default: "")
String: Returns or sets the property to use as the actual value for the items in the ListControl. (Default: "")
Throws:
ArgumentException The specified property cannot be found on the object specified by the DataSource property.
Boolean: Enables or disables virtual scrolling for the ListControl. When virtual scrolling is enabled, only the visible items are rendered in the browser allowing the ListControl to host virtually unlimited items without any performance loss. (Default: False)
When VirtualScroll is set to true, all the items must be of the same height, limiting the more flexible HTML rendering available when VirtualScroll is off (default). Setting the property PrefetchItems to a value greater than 0 allows the virtual view to prefetch the specified number of items outside of the visible area to enable smoother scrolling. Throws:
InvalidOperationException Horizontal orientation is not supported with virtual scrolling.
Populates the ListControl from the data appending the items to the existing items.
