[Solved] Load On Demand server side

[krishnamraju]

I have tree view which will load child nodes on demand. iam using the server side expansion.After node expand,iam not able to select the node(Tree Structure is also not coming, its coming like only text).
Before node Expand:
  

RadTreeNode nodeclicked = e.NodeClicked;

AddChildNodes(nodeclicked);

}

private void AddChildNodes(RadTreeNode node)

{

string[] str2 =node.Value.ToString().Split('-');

if (str2[1] == "CIRCLE")

{

svt_Circle objCircle = new svt_Circle();

DataTable dtblCirInfo = objCircle.GetCircleDetails();

DataView dvSubCir = new DataView(dtblCirInfo);

dvSubCir.RowFilter =

"ParentCircleId='" + str2[0].ToString() + "'";

foreach (DataRowView row in dvSubCir)

{

RadTreeNode node1 = new RadTreeNode();

node1.Text = (

string)row["CIRCLENAME"];

node1.Value = row[

"CircleID"].ToString();

node1.Value +=

"-" + svt_Utils.Levels.SUBCIRCLE.ToString();

node1.ToolTip =

"SUB-CIRCLE";

node1.Category =

"Sub Circles";

node1.CssClass =

"TreeNodeGreen";

node1.CssClassOver =

"TreeNodeHover";

node1.ExpandMode =

ExpandMode.ServerSide;

node.Nodes.Add(node1);

}

node.Expanded =

true;

 }

}

Please help,Thanks in advance.

Hi krishnamraju,

This is indeed weird. I suggest that you refer to our online example that show similar approach:

Server-side LOD

If this does not help, can you put together a small and running example showing the matter? You can attach the files to a new support thread. We will test them locally and try to find a working solution for you.
