Sir , how i can handle javasciprt and ajax on
imagemap.

sir
can we add attribute for the events and to be effect of it...
just like this
FlowChart1.Attributes.Add("OnTreeExpanded", "alert(); return false;");
..i m trying with it.

Sir
I used to savetostring and loadfromstring method.
hw i can extract value which I used to save to extract information about flowchart to again modifying flowchart and saveto again .

Sir ,
when I am creating box. after that I m saving it as a value . I m expanding node ..now it calls event
handler of expanded tree , it modifying the layout
tree, but problem is that it is not showing expanding node as expanded, even that I hav solved it also by this Way ...
protected void FlowChart1_TreeExpande(objectsender, NodeEventArgs e)
{


FlowChart1.LoadFromString(Convert.ToString(Hiddensaveflowchart.Value));



Hashtable childToParent = new Hashtable();




string expandednodeid = "";


if (e.Node is Box)

{


expandednodeid = e.Node.Tag.ToString();


e.Node.Expandable = true;


e.Node.Expanded = true;




}



chartTable = (SessionDataSet.ScheduleChartDataTable)GetBLSession("ScheduleChartTable");

DataView dv = chartTable.DefaultView;


////filter for the parent

dv.RowFilter = " ParentID = '" + expandednodeid.ToString() + "'";





for (int i = 0; i < dv.Count; i++)

{


string IsDel = dv[i]["IsDelete"].ToString().ToLower() == "false" ? "0" : (dv[i]["IsDelete"].ToString().ToLower() == "true" ? "1" : dv[i]["IsDelete"].ToString());



if (IsDel != "1")




{



Box node = FlowChart1.CreateBox(0, 0, 15, 10);



string nodeID = dv[i]["NodeID"].ToString();



node.Text = dv[i]["NodeName"].ToString();



string parentID = dv[i]["ParentID"].ToString();



node.Tag = nodeID;



node.EnabledHandles = Handles.All;



node.HandlesStyle = HandlesStyle.DashFrame;



node.Expandable = true;



node.Expanded = false;



node.FillColor = Color.Wheat;



childToParent[nodeID] = parentID;


}





}


foreach (Box b in FlowChart1.Boxes)

{


if (!childToParent.ContainsKey(b.Tag))


continue;



FlowChart1.CreateArrow(FlowChart1.FindBox(childToParent[b.Tag]), b);

}


TreeLayout tl = new TreeLayout();

tl.Arrange(FlowChart1);

Hiddensaveflowchart.Value = FlowChart1.SaveToString();

}

Sir,
thanks for this info...now worked fine.
Sir, When I am collepsing node ,after that I am expanding Same node ,its child is coming with duplicates mean it has same childs attaching 2 time
with node.
  protected  void FlowChart1_TreeCollapsed(object sender, NodeEventArgs e)
    {
FlowChart1.LoadFromString(Convert.ToString(Hiddensaveflowchart.Value));
if (e.Node is Box)
      {
    Box a = FlowChart1.FindBox(e.Node.Tag.ToString());
        a.Expandable = true;
        a.Expanded = false;
        a.FillColor = Color.Brown;
        a.Collapse();
         a.Detach();

       }
      
      
     TreeLayout tl = new TreeLayout();
      tl.Arrange(FlowChart1);

       Hiddensaveflowchart.Value FlowChart1.SaveToString();
}

Sir
there is any option to remove child node from tree
when we are collapsing any particular node, and after that we save that flowchart by savetostring().

kirtesh

   for (int i = 0; i < rows.Length; i++)
           {
                string childnodeid = rows[i]["NodeID"].ToString();
               Box deletebox = FlowChart1.FindBox(childnodeid);
               FlowChart1.DeleteObject(deletebox);
           }
Sir
I used this code ,Sir after deleting any node,it 
deletes  its child node or not, bydefault..or I have to make code for that, what about to removes arrow prob.. that is cming. myside..
it may bcoz I m not deleting objects of arrow..
May i RIGHT ..hw  to solve it .

Sir
thanks for this info...I worked successfully on it .
Sir , on the page some times when first node is loaded by one method(mean there is only one node on the flowchart), on pageload time at the first time.when I want to expand it ...but it is calling collapsed eventhandler
protected void FlowChart1_TreeCollapsed(object sender, NodeEventArgs e)
and now same node is being collapsed while ..I want to expand it...what reason may be behind of it ?
it is calling expanded event handler on second time and wrking fine.

why it is not calling expand eventhandler at the first time?
