Step 1: Call the Service

Complete the following steps to call the Web API service.

Add C1 Web API Client JavaScript file and its reference to your MVC or HTML project.

Add import functionality, using Client JavaScript Helper, which will be triggered on button click event. MVC

Add the following code to Views|MVCFlexGrid**|**Index.cshtml to import excel data into FlexGrid control.

<script type="text/javascript">
    var gridcontrol;
    c1.mvc.Utils.documentReady(function () {
        gridcontrol = wijmo.Control.getControl('#flexGrid')
    });
    function importFlex() {
    var file = document.getElementById("fileInput").files[0];
    var importer = new wijmo.grid.ExcelImporter();
    importer.requestImport(gridcontrol,
    "http://demos.componentone.com/ASPNET/C1WebAPIService/api/import/excel", file, true)
    }
</script>

HTML

Add the following markup in <script> tags to import excel data into FlexGrid control.

<script>
var grid;
$(document).ready(function() {
  grid = wijmo.Control.getControl('#TheGrid')
});
function importFlex() {
  var file = document.getElementById("fileInput").files[0];
  var importer = new wijmo.grid.ExcelImporter();
  importer.requestImport(grid,
  "https://demos.componentone.com/ASPNET/WebAPI/api/import/excel",
  file, true)
}
</script>

Note: To use Wijmo 5 controls in your HTML application, you need to include references to few Wijmo files in your HTML pages. You may either download these wijmo files and copy them to appropriate folders in your application, or reference Wijmo files hosted in cloud on our Content Delivery Network (CDN). If you download and place the Wijmo script files in a folder named "Scripts", css files in a folder named "Styles", and script files specific to Wijmo controls to "Controls" folder, then add the following references within <head> tags of your HTML pages:
<script src="Controls/wijmo.min.js" type="text/javascript"></script>
<link href="Styles/wijmo.min.css" rel="stylesheet" type="text/css" />
<script src="Scripts/jquery-1.10.2.min.js" type="text/javascript"></script>
<script src="Controls/wijmo.grid.min.js" type="text/javascript"></script>
<script src="Scripts/webapiclient.min.js" type="text/javascript"></script>

Provide an input control, for example button, to initiate import request in client application. MVC
- Add the following code in Views | MVCFlexGrid | Index.cshtml to add buttons for export and import functionalities.
Add the following code in Views | MVCFlexGrid | Index.cshtml to add buttons for import functionality.
