Hi everybody , I want to Refresh a layer programmatically during run time
I’m using IinformationTree to find the layer , and GetLayer Method to get That Layer that i want to refresh
Here is the code 
  
       var ItemID = IInformationTree.FindItem ("mylayername");
      if(IInformationTree.IsLayer(ItemID))
          {
           var mylayer; 
           mylayer = IInformationTree.GetLayer(ItemID);
           mylayer.Refresh();
 
          }

BUT when I run this code , I get a message that the object does not support  this property or methode
Can someone help me ?
Thanks and best regards

aeshaq, your code works for me.

Check what line the error refers to and check the variable values.

Here is my full code:

 

<HTML><BODY>


<OBJECT id=TE classid=CLSID:3a4f9191-65a8-11d5-85c1-0001023952c1></OBJECT>
<FORM name="form0">
<INPUT type="button" value="aaa" name="btnaaa" onclick="aaa();">
</FORM>
<script language="javascript" >
function aaa()
{
IInformationTree = TE.interface("IInformationTree5");
var ItemID = IInformationTree.FindItem ("mylayername");
if(IInformationTree.IsLayer(ItemID))
{
var mylayer; 
mylayer = IInformationTree.GetLayer(ItemID);
mylayer.Refresh();
} 
}
</script>
</BODY>
</HTML>
