images changing when node is expanded(urgent)
posted

Hi,

  when I load the tree with custom images, they are displaying correctly, but when I expand the node, the expanded node image is reset to some default minus image.

I am using netadvantage volume 2007 version 7.1

 here is the code. please help. I posted a question earlier, but there was no response.

 <ignav:ultrawebtree id="UltraWebTree1" runat="server" WebTreeTarget="HierarchicalTree" LoadOnDemand="ManualSmartCallbacks"

ImageDirectory="~/images/infragistics" OnDemandLoad="UltraWebTree1_DemandLoad" >

<Images>

<ExpandImage Url="ig_treeXPPlus.GIF" />

<CollapseImage Url="ig_treeXPMinus.GIF" />

</Images>

</ignav:ultrawebtree>

and the code-behind

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

Infragistics.WebUI.UltraWebNavigator.Node node = UltraWebTree1.Nodes.Add("root");node.ShowExpand = true;

}

}

protected void UltraWebTree1_DemandLoad(object sender, WebTreeNodeEventArgs e)

{

Infragistics.WebUI.UltraWebNavigator.Node node = e.Node.Nodes.Add("child1");

node.ShowExpand = true;

node = e.Node.Nodes.Add("child2");

node.ShowExpand = true;

}
