Hi, we're using syncfusion grid, now depending of a external value we're need change the header text of the grid.

Example: We manage Ton and Kg, this value is saved in a variable. Now have a column Weight and depending of the value in the variable we want add Ton or Kg for show of this form:

Weight (Ton) ---- or ---- Weight (Kg)

Exist a form for make this having a instance of the grid?

Hi Roimer, 

Thanks for contacting Syncfusion support. 

We have analyzed your query and based on your requirement we have prepared a sample that can be available from the below link. 
In this sample we have changed the headerText based on the value given in the textBox. To change the headerText initially we have used load event in grid. After changing the value in the text box then clicking the button we have called updateHeader method. In the updateHeader method we have change the headerText for the columns in grid. 
Please refer the below code example. 
 
<input id="measurement" value="Ton" /> <button id="btn">Change HeaderText</button> 
        <div id="Grid"></div> 
    </div>/div> 
      <script type="text/javascript"> 
        $(function () { 
            var element = $("#Grid"); 
            element.ejGrid({ 
                dataSource: window.gridData, 
                allowPaging: true, 
                load: "load", 
                columns: [ 
                             { field: "OrderID", headerText: "Order ID", isPrimaryKey: true, textAlign: ej.TextAlign.Right, width: 90 }, 
                             { field: "EmployeeID", width: 90 } 
                ] 
            }); 
            $("#btn").bind("click", function (args) { 
                var grid = $("#Grid").ejGrid("instance"); 
                updateHeader(); 
                grid.refreshHeader(); // Refresh the header alone 
            }); 
        }); 
        function load(args) { 
            updateHeader(); 
        } 
        function updateHeader() { 
            var measurementValue = $("#measurement").val(); 
            var grid = $("#Grid").ejGrid("instance"); 
            var index = grid.getColumnIndexByField("EmployeeID"); 
            grid.model.columns[index].headerText = "Weight(" + measurementValue + ")"; 
        } 
    </script>
