hi,
I try to make a tree view dynamically by assigning data from database. I want to have image for collapse and expand but when I retrieve it from db, instead of showing the image it shows the image path.
Please tell me what I can do to solve this issue.
Here is my code
<eo:TreeView ID="tvMilestone" runat="server" ControlSkinID="None" AutoScroll="False" DataFields="chCollapseImage|chPageDesc" RaisesServerEvent="True" >

<LookNodes>
<eo:TreeNode DisabledStyle-CssText="" ItemID="_TopLevelItem" NormalStyle-CssText=""
SelectedStyle-CssText="">
<SubGroup Style-CssClass="programmenunodetop" Style-CssText="">
</SubGroup>
</eo:TreeNode>
<eo:TreeNode HoverStyle-CssClass="programmenunodehover" ItemID="_Default" NormalStyle-CssClass="programmenudefault"
SelectedStyle-CssClass="programmenunodeselect">
<SubGroup Style-CssText="">
</SubGroup>
</eo:TreeNode>
</LookNodes>
<Margin Width="0" />
<TopGroup Style-CssClass="programtreeview">
<Bindings>
<eo:DataBinding

Property="CollapsedImageUrl"
DataField="chCollapseImage"
Depth=0
/>
<eo:DataBinding
Property="ExpandedImageUrl"
DataField="chExtendImage"

Depth=0/>
</Bindings>
<Nodes>
<eo:TreeNode
ShowCheckBox="False" RaisesServerEvent="True" PopulateOnDemand="True">
<SubGroup>
<Nodes>
<eo:TreeNode RaisesServerEvent="True" >

</eo:TreeNode>
</Nodes>
<Bindings>
<eo:DataBinding DataField="chMilestoneDesc" />
</Bindings>
</SubGroup>
</eo:TreeNode>
</Nodes>
</TopGroup>
<LineImages Visible="False" />
</eo:TreeView>

Hi,

The problem is caused by:

Code: HTML/ASPX 
DataFields="chCollapseImage|chPageDesc"


When you use DataFields, whatever you put there goes into node Text, unless you explicitly override it with a DataBinding object:

Code: HTML/ASPX 
<eo:DataBinding Property="Text-Html" DataField="chPageDesc"/>


Without the above data binding object, node on the first level will take chCollapseImage as node text as you have noticed.

Thanks
