How to: Display Item Headers in a DataRepeater Control (Visual Studio)
The item header in a DataRepeater control provides a visual indicator when a DataRepeaterItem is selected. When the LayoutStyle property is set to Vertical (the default), the item header is displayed to the left of each item. When the LayoutStyle property is set to Horizontal, the item header is displayed at the top of each item.
When it is first selected, the item header is displayed in the color that is specified by the SelectionColor property, and a white arrow icon is displayed.
Note
If you set the SelectionColor to White, the selection symbol will not be visible when the item is first selected.
When a field in the DataRepeaterItem has focus, the color of the item header changes to the ItemTemplate background color and the arrow icon changes to black. If data is changed, a pencil symbol is displayed in the item header.
The default width (or height when the LayoutStyle property is set to Horizontal) of the item header is 15 pixels. You can change the width by setting the ItemHeaderSize property.
Note
If the ItemHeaderSize property is set to a value that is less than 11, the indicator symbols in the item header will not be displayed.
You can hide the item headers by setting the ItemHeaderVisible property to False. When ItemHeaderVisible is set to False, the only indication that an item is selected is a dotted line around the perimeter of the DataRepeaterItem.
Note
You can also provide your own selection indicator by monitoring the IsCurrent property of the DataRepeaterItem in the DrawItem event of the DataRepeater control. For more information, see IsCurrent.
