Hi,

I have an EO treeview in our .net application .
design (.aspx) code is given below:

<eo:TreeView ID="libTreeView" runat="server" AutoWrap="True" AutoSelectSource="ItemClick"
OnItemPopulate="libTreeView_ItemPopulate" ClientSideOnContextMenu="showLibraryContextMenu" SingleExpandMode="AllLevels" >
<CheckBoxImages Visible="True" Margin="3"></CheckBoxImages>
<LineImages Visible="False"></LineImages>
<TopGroup Style-CssText="cursor:hand; font-family:Arial, Sans-Serif;font-size:medium;" >
<Nodes>
</Nodes>
</TopGroup>
<LookNodes>
<eo:TreeNode ImageUrl="Blank" CollapsedImageUrl="00030501" ExpandedImageUrl="00030502" ItemID="_Default"
NormalStyle-CssText="padding-right: 3px; padding-left: 3px; padding-bottom: 2px; padding-top: 3px;"
SelectedStyle-CssText="border-right: #8396c3 1px solid; padding-right: 2px; border-top: #8396c3 1px solid; padding-left: 2px; padding-bottom: 1px;
border-left: #8396c3 1px solid; padding-top: 1px; border-bottom: #8396c3 1px solid; background-color: #f2f5fb;"
HoverStyle-CssText="border-right: #8396c3 1px solid; padding-right: 2px; border-top: #8396c3 1px solid; padding-left: 2px; padding-bottom: 1px;
border-left: #8396c3 1px solid; padding-top: 1px; border-bottom: #8396c3 1px solid; background-color: #f2f5fb;">
<SubGroup ItemSpacing="8"></SubGroup>
</eo:TreeNode>
</LookNodes>
</eo:TreeView>


I have populating data into 'treeview ' in pageload.

I have given some example given below:

the treeview looks like


+Example1
+Example2
+Example3 and so on ...


when we click on the '+' in the Example1.It shows under it as

Example1
+test1
+test2

test1 ,test2 have child items ...

My requirement is when we click on the Expample1 should expand all items (incliding child items).

that means Click on +Example1 should be

Example1
test1
test11
test2
test12 and so on..


I have set 'SingleExpandMode="AllLevels" ' but it does not meet my requirement.

Could you please send me the solution of it?
