Hi  I am using control : Webhierarchicaldatagrid  version :Version=9.2.20092.2183

In my Webhierarchicaldatagrid  i am having child grid.In that child grid i am having link button as template column.If i click child grid link button i got some javascript error like " this._rowIslands[i].dispose(); /// Here i got null or not an object error".

this javasacript calling "dispose function"  implicitly.in that time i got error.that is why i cannot able to changes in the code.

I have added code sample  where i got error in implict calling javascript function.

sample code:

dispose: function ()
 {
  ///<summary>
  ///Disposes of the ContainerGridRow object.
  ///</summary>

  delete this._rowIsland;
  delete this._expanded;

  if (this._expColBtn)
   this._expColBtn.dispose();
  delete this._expColBtn;
  if (this._animation)
   this._animation.dispose();
  delete this._animation;
  for (var i = 0; this._rowIslands && i < this._rowIslands.length; i++)
  {
   //if (this._rowIslands[i])
   this._rowIslands[i].dispose(); /// Here i got null or not an object error
  }
  delete this._rowIslands;
  $IG.ContainerGridRow.callBaseMethod(this, "dispose");
 },

How can i resolve this error.can please tell me this is very urgent .I am waiting your reply eagerly.

Note:

Please dont tell me to use infragistics 10.2  version.Because already i aware that in 10.2 version service release you people already resolved this issue.

Unfortunatenly i cannot use infragistics 10.2  version.

Currently i am using infragistics 9.2  version . I have tried some 9.2 version latest service release also
