JSON Call in SigmaGrid 2.0

[bshafs]

I have been trying to bind a grid using the example-paging.html document which came with the 2.0 package.
So far, after the line return ResponseT is executed, nothing happens and the grid remains blank.  There is no error message thrown.

I am using a SigmaRequest() object to retrieve JSON code from another page.  FireBug has confirmed the JSON is in the proper format.  I have also executed the .slice() method to verify it parses the JSON correctly.

Here is my code

var __MY_DATA__; function getEmployeeData(grid){        var request = new SigmaRequest();    request.open("get","MyController.aspx",true);    request.onResult = function(){             var results = request.getValue();             __MY_DATA__  = results;             //Continue to bind data             var responseT={};             var pageInfo= grid.getPageInfo();             responseT[grid.CONST.data]=__MY_DATA__.slice( pageInfo.startRowNum-1,pageInfo.endRowNum);             responseT[grid.CONST.pageInfo]={totalRowNum :__MY_DATA__.length } ;             return responseT;    }    request.send();   } var gridOption={ ...data settings unchanged from example_paging.html.. dataset : MyDsOption , columns : myColsOption , defaultRecord : ["","","","",""], loadUrl : getEmployeeData, ...data settings unchanged from example_paging.html.. };

Objects MyDsOption and myColsOption are modifications from the original dsOption and colsOption which were trimmed down to match the number of columns in my datam which is five.

If anyone can help me I would appreciate it so much. I have spent several hours and have gotten nowhere.  I am at a dead end. 

Thank you.

I think you are talking about paginal outpout on client. You need to do a quest synchronously.  The following code snippet may give you some ideas.

function getEmployeeData(grid) {
  var responseT={};
  var req = (window.XMLHttpRequest)?new XMLHttpRequest()(window.ActiveXObject)?new ActiveXObject("Microsoft.XMLHTTP"):false);
  if(req){
    var pageInfo = grid.getPageInfo();
    req.open("GET", "Controller.php?pageNum=" + pageInfo.pageNum, false);//the third param must be false
    req.send(null);
    var json=eval(req.responseText);
    ...
}

}
