exporting only the filtered data

Hi,

I wanted to export the data that I have binded to grid. But, I am filtering the grid data by passing input. Based on the input, the grid data will be filtered. So, If I filter by order number only those filtered data needs to be exported. How can I achieve this? 

I am mentioning the service that I am binding to grid. 

switch(String(input))
{
case "All":

var params = {
From: From /* DATETIME */,
To: To /* DATETIME */
};

// result: INFOTABLE dataShape: "Navistar_RejectedOrder_DS"
sampleResult = me.Get_RejectedOrderAll(params);

break;
//

case "Part Number":

var params = {
From: From /* DATETIME */,
To: To /* DATETIME */,
partNumber: partNumber /* STRING */
};

// result: INFOTABLE dataShape: "Navistar_RejectedOrder_DS"
sampleResult = me.Get_RejectedOrder_partNumber(params);

break;
//
case "Job Number":

var params = {
From: From /* DATETIME */,
To: To /* DATETIME */,
jobNum: jobNumber /* STRING */
};

// result: INFOTABLE dataShape: "Navistar_RejectedOrder_DS"
sampleResult = me.Get_RejectedOrder_JobNumber(params);

break;

case "Line Set":

var params = {
From: From /* DATETIME */,
To: To /* DATETIME */,
lineSet: lineSetNumber /* STRING */
};

// result: INFOTABLE dataShape: "Navistar_RejectedOrder_DS"
sampleResult = me.Get_RejectedOrder_lineSet(params);

break;

}

if (input == null || input == "")
{

var params = {
From: From /* DATETIME */,
To: To /* DATETIME */
};

// result: INFOTABLE dataShape: "Navistar_RejectedOrder_DS"
sampleResult = me.Get_RejectedOrderAll(params);

}

if (From == null || From == "" || To == null || To == "")
{

// result: INFOTABLE dataShape: "Navistar_RejectedOrder_DS"
sampleResult = me.Get_RejectedOrderNoFilter();

}

var result1 = sampleResult;

var params2 = {

t: result1/* INFOTABLE */,

query: query /* QUERY */

};

// result: INFOTABLE

var result = Resources["InfoTableFunctions"].Query(params2);

Thanks,
