dynamic schema data in grid

[Gerd]

Is there a possibility to aggregate the grid schema dat aon the fly with ajax? I tested ist with a function but it didn't work.
i.e.:
It seems not to work cause if the data format, i guess ... any idea?

in the grid object:
schema: getSchema()


the function:
function getSchema()
{
var dataReturn;
    $.ajax({
        url: "/ajax/listen/getschema",
        success: function(data){
            console.log(data);
            dataReturn = eval( "("+ data +")");
        },
        error: function(data){
            console.log(data.responseText);
        },
        complete: function(jqXHR, textStatus){
            console.log(jqXHR);
            console.log(textStatus);
        }
    });
    return dataReturn;
}

You are trying to return data from an asynchronous call, which can by definition not work because your getSchema() function will return before success is called, therefore always yielding an empty return value.
You could try setting "async: false" in the ajax object and have the success function set a global variable that can then be returned.
