The source of the problem is hiding in the "Block" Html elements ( <table> , <div>, etc) that are automatically placed on a new line and thus potentially breaking the desired design and position of the template in the treeview hierarchy.
If you need to use block elements for your <NodeTemplate>, make sure you add the css display:inline style to the root tag.
Example:
| ASPX |
 Copy Code |
|
...
<NodeTemplate>
<table style="display:inline">
<tr>
<td> ... </td>
<td> ... </td>
<td> ... </td>
</tr>
</table>
<NodeTemplate>
...
...
<NodeTemplate>
<div style="display:inline">
...
</div>
<NodeTemplate>
...
