I'm creating an Umbraco website, and I am creating a plugin for the backend of Umbraco so a user can export an Excel worksheet from an HTML table. I'm using AngularJS and a C# controller to do this. Here are my files.
//This is my C# Controller at /App_Code/ExportBlankDictionaryController.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Umbraco.Web.Editors;
using Umbraco.Core.Persistence;
using System.Data.SqlClient;
using System.Web.UI.WebControls;
using System.Web.UI;
using System.IO;
namespace AngularUmbracoPackage.App_Code
{
[Umbraco.Web.Mvc.PluginController("AngularUmbracoPackage")]
public class ExportBlankDictionaryController : UmbracoAuthorizedJsonController
{
//[System.Web.Http.AcceptVerbs("GET", "POST")]
//[System.Web.Http.HttpGet]
public void ExportExcell()
{
var keys = new System.Data.DataTable("BlankDictionaryItems");
keys.Columns.Add("Keys", typeof(string));
keys.Columns.Add("Description", typeof(string));
keys.Rows.Add("Enter First Dictionary Name Here", " ");
var grid = new GridView();
grid.DataSource = keys;
grid.DataBind();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.BufferOutput = true;
HttpContext.Current.Response.AddHeader("Content-disposition", "attachment; filename=BlankDictionaryItems.xls");
HttpContext.Current.Response.ContentType = "application/vnd.ms-excel";
HttpContext.Current.Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
grid.RenderControl(htw);
HttpContext.Current.Response.Output.Write(sw.ToString());
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
}
}
// This is my AngularJS controller at /App_Plugins/datatable/datatable.controller.js:
angular.module("umbraco")
.controller("AngularUmbracoPackage.ExportBlankDictionaryController", function ($scope, keyResource) {
keyResource.exportToExcell().then(function (response) {
alert("Table Generated!");
})
});
This is my datatable.resource.js file within the same directory:
// Adds the resource to umbraco.resources module:
angular.module('umbraco.resources').factory('keyResource',
function ($q, $http) {
// The factory object returned
return {
// This calls the API controller we setup earlier
exportToExcell: function () {
console.log("button clicked");
return $http.post("backoffice/AngularUmbracoPackage/ExportBlankDictionary/ExportExcell");
}
};
}
);
If necessary, here is the package.manifest.json file:
{
propertyEditors:[
{
name: "DataTable editor",
alias: "my.datatable.editor",
editor:{
view: "~/app_plugins/datatable/table.html",
valueType: "JSON"
}
}
],
javascript: [
"~/app_plugins/datatable/datatable.controller.js",
"~/app_plugins/datatable/datatable.resource.js"
]
}
Here is the table.html file which is the view:
<div class="ExportDiv" ng-controller="AngularUmbracoPackage.ExportBlankDictionaryController">
<table id="table1" class="table table-bordered" runat="server">
<thead>
<tr>
<th>Key</th>
<th>Populate Dictionary Item Names in Key Column</th>
</tr>
</thead>
<tbody>
<tr>
<td>Enter First Dictionary Name Here</td>
<td></td>
</tr>
</tbody>
</table>
</div>
<button class="btn btn-success" ng-click="exportToExcel()">Export Table</button>
Okay, so the Umbraco page is loading, the alert box comes up when the developer section of Backoffice is opened, but when I click the Export Table button, nothing happens. I am trying to get an Excel sheet to download when this button is clicked. How can I do this? Am I missing something?
Add
angular.module("umbraco")
.controller("AngularUmbracoPackage.ButtonController", function ($scope, keyResource) {
$scope.ButtonClickHandler = function(){
console.log("clicked me!");
keyResource.exportToExcell().then(function (response) {
//do something with the response from the server
}
});
then change the button element to:
<button ng-controller="AngularUmbracoPackage.ButtonController" class="btn btn-success" ng-click="ButtonClickHandler()">Export Table</button>
