CheckBoxList.IRepeatInfoUser.GetItemStyle Method (ListItemType, Int32)
This API supports the product infrastructure and is not intended to be used directly from your code.
For a description of this member, see IRepeatInfoUser.GetItemStyle.
Assembly: System.Web (in System.Web.dll)
Private Function GetItemStyle ( itemType As ListItemType, repeatIndex As Integer ) As Style Implements IRepeatInfoUser.GetItemStyle
Parameters
- itemType
-
Type:
System.Web.UI.WebControls.ListItemType
One of the ListItemType enumeration values.
- repeatIndex
-
Type:
System.Int32
An ordinal index that specifies the location of the item in the list control.
Return Value
Type: System.Web.UI.WebControls.StyleA Style object that represents the style of the specified item type at the specified index in the list control.
Typically, you should use the CheckBoxList.GetItemStyle method to retrieve the style of an item in a CheckBoxList object.
The IRepeatInfoUser.GetItemStyle method is an explicit interface member implementation. It can be used only when the CheckBoxList instance is cast to an IRepeatInfoUser interface.
Notes to Implementers:
To define a custom implementation for retrieving the style of an item in a CheckBoxList object, override the CheckBoxList.GetItemStyle member. The explicit interface implementation calls the CheckBoxList.GetItemStyle method to retrieve the style of an item.
The following code example demonstrates how to use the IRepeatInfoUser interface members on a custom CheckBoxList object.
