Hi Gustavo, 

Thanks for contacting Syncfusion support.  

Based on your query we suspect that you are facing issue while printing the Grid. We have prepared a Grid using your code example and we are able to reproduce the some issue while printing. Refer the below screenshot for the error. 

 

If you are facing the above issue,  then we suggest you to make changes in server side. The root cause of the issue is while printing the Skip and Take value will be 0. So kindly check the below condition for Skip and Take value. 

PHP 

<?php 
 
//session_start(); 
 
//include("connection.php"); 
 
?> 
 
<?php 
/** 
* Created by PhpStorm. 
* User: christopheweibel 
* Date: 16/01/15 
* Time: 12:20 
*/ 
header("Content-type:application/json"); 
$link = mysqli_connect('localhost', 'root', '', 'mysql'); 
 
$json_param = file_get_contents("php://input"); 
$params = json_decode($json_param,true); 
/* check connection */ 
if (!$link) { 
    printf("Connect failed: %s\n", mysqli_connect_error()); 
    exit(); 
} 
 
$filterQuery = NULL; 
$skip = isset($params['skip']) ? $params['skip'] : 0 ; 
$take = isset($params['take'])  ? $params['take'] : 0; 
 
$search = isset($params['search']) ? $params['search'] : NULL ; 
$filter = isset($params['where']) ? $params['where'] : NULL ; 
$sort = isset($params['sorted']) ? $params['sorted'] : NuLL ; 
$select = isset($params['select']) ? $params['select'] : NuLL ; 
$query =$sql = "SELECT * FROM help_category"; 
 
/* Searching operation */ 
.                 .               .         .       .  
 
if($take != null && $take > 0){ 
    $query = $query." limit ".$skip.",".$take;  //perform skip and take operation 
} 
 
$result = mysqli_query($link,$query); 
 
$json=array(); 
 
while ($row = mysqli_fetch_array($result)) { 
    array_push($json,array( 
                           'help_category_id' => $row{'help_category_id'}, 
                           'name' => $row{'name'}, 
                           'parent_category_id' => $row{'parent_category_id'}, 
                            
                          )); 
} 
.     .          .              .                .            .  
/* Selection Operation */ 
 
?> 
 


Or if you are using C# 
[C#] 
public ActionResult UrlDataSource(DataManager dm) 
        { 
 
            IEnumerable DataSource = OrderRepository.GetAllRecords(); 
            DataOperations ds = new DataOperations(); 
            List<string> str = new List<string>(); 
            if (dm.Search != null && dm.Search.Count > 0) 
            { 
                DataSource = ds.PerformSearching(DataSource, dm.Search); 
            } 
            if (dm.Sorted != null && dm.Sorted.Count > 0) //Sorting 
            { 
                DataSource = ds.PerformSorting(DataSource, dm.Sorted); 
            } 
            if (dm.Where != null && dm.Where.Count > 0) //Filtering 
            { 
                DataSource = ds.PerformWhereFilter(DataSource, dm.Where, dm.Where[0].Operator); 
            } 
            
            var count = DataSource.Cast<EditableOrder>().Count();            
            DataSource = ds.PerformSkip(DataSource, dm.Skip);            
            if (dm.Take != null && dm.Take > 0) 
            { 
                DataSource = ds.PerformTake(DataSource, dm.Take); 
            } 
            return Json(new { result = DataSource, count = count }); 
        } 

If the above issue that you are not facing in your application, kindly share more details(screenshot of an issue, Essential Studio Version details) regarding the issue that you are facing in your application

I Attack my server-side code

My code include

$skip = isset($params['skip']) ? $params['skip'] : 0 ; 
$take = isset($params['take'])  ? $params['take'] : 0; 



if($take != null && $take > 0){ 
    $query = $query." limit ".$skip.",".$take;  //perform skip and take operation 
} 

But still appear blank page.
