Members
| Member name | Description |
|---|
| Table | Items are displayed in a table. The following example shows markup that is rendered for a CheckBoxList control whose RepeatLayout property is set to Table. .gif) Note
<table id="ctl00_MainContent_CheckBoxList2">
<tr>
<td>
<input id="ctl00_MainContent_CheckBoxList2_0" type="checkbox"
name="ctl00$MainContent$CheckBoxList2$0" value="Item 1" />
<label for="ctl00_MainContent_CheckBoxList2_0">Item 1</label>
</td>
</tr>
<tr>
<td>
<input id="ctl00_MainContent_CheckBoxList2_1" type="checkbox"
name="ctl00$MainContent$CheckBoxList2$1" value="Item 2" />
<label for="ctl00_MainContent_CheckBoxList2_1">Item 2</label>
</td>
</tr>
<tr>
<td>
<input id="ctl00_MainContent_CheckBoxList2_2" type="checkbox"
name="ctl00$MainContent$CheckBoxList2$2" value="Item 3" />
<label for="ctl00_MainContent_CheckBoxList2_2">Item 3</label>
</td>
</tr>
</table>
| | Flow | Items are displayed without a table structure. Rendered markup consists of a span element and items are separated by br elements. The following example shows markup that is rendered for a CheckBoxList control whose RepeatLayout property is set to Flow.
<span id="ctl00_MainContent_CheckBoxList1">
<input id="ctl00_MainContent_CheckBoxList1_0" type="checkbox"
name="ctl00$MainContent$CheckBoxList1$0" value="Item 1" />
<label for="ctl00_MainContent_CheckBoxList1_0">Item 1</label>
<br />
<input id="ctl00_MainContent_CheckBoxList1_1" type="checkbox"
name="ctl00$MainContent$CheckBoxList1$1" value="Item 2"/>
<label for="ctl00_MainContent_CheckBoxList1_1">Item 2</label>
<br />
<input id="ctl00_MainContent_CheckBoxList1_2" type="checkbox"
name="ctl00$MainContent$CheckBoxList1$2" value="Item 2" />
<label for="ctl00_MainContent_CheckBoxList1_2">Item 2</label>
</span>
| | UnorderedList | Items are displayed without a table structure. Rendered markup consists of a ul element that contains li elements. The following example shows markup that is rendered for a CheckBoxList control whose RepeatLayout property is set to UnorderedList.
<ul id="ctl00_MainContent_CheckBoxList4">
<li>
<input id="ctl00_MainContent_CheckBoxList4_0" type="checkbox"
name="ctl00$MainContent$CheckBoxList4$0" value="Item 1" />
<label for="ctl00_MainContent_CheckBoxList4_0">Item 1</label>
</li>
<li>
<input id="ctl00_MainContent_CheckBoxList4_1" type="checkbox"
name="ctl00$MainContent$CheckBoxList4$1" value="Item 2" />
<label for="ctl00_MainContent_CheckBoxList4_1">Item 2</label>
</li>
<li>
<input id="ctl00_MainContent_CheckBoxList4_2" type="checkbox"
name="ctl00$MainContent$CheckBoxList4$2" value="Item 2" />
<label for="ctl00_MainContent_CheckBoxList4_2">Item 2</label>
</li>
</ul>
Note | | OrderedList | Items are displayed without a table structure. Rendered markup consists of an ol element that contains li elements. The following example shows markup that is rendered for a CheckBoxList control whose RepeatLayout property is set to OrderedList.
<ol id="ctl00_MainContent_CheckBoxList3">
<li>
<input id="ctl00_MainContent_CheckBoxList3_0" type="checkbox"
name="ctl00$MainContent$CheckBoxList3$0" value="Item 1" />
<label for="ctl00_MainContent_CheckBoxList3_0">Item 1</label>
</li>
<li>
<input id="ctl00_MainContent_CheckBoxList3_1" type="checkbox"
name="ctl00$MainContent$CheckBoxList3$1" value="Item 2" />
<label for="ctl00_MainContent_CheckBoxList3_1">Item 2</label>
</li>
<li>
