Getting errro at ControllerContext after calling Action from another controller:-
var pdfBytes = new ViewAsPdf("MonthlyReport", GetOverAllSales)
{
PageWidth = 215.9,
PageHeight = 279.4,
PageMargins = new Rotativa.Options.Margins(4, 6, 4, 4)
}.BuildFile(ControllerContext);
var fileName = "MonthlySalesReport_" + DateTime.Now.Ticks + ".pdf";

I have form for upload file and i want to upload thumbnail for the file in the same form I am doing that with this part of code :
var basePath2 = Path.Combine(Directory.GetCurrentDirectory() + "\\Thumbnails\\");
bool basePathExists2 = System.IO.Directory.Exists(basePath2);
if (!basePathExists2)
Directory.CreateDirectory(basePath2);
var thumbnailPath = Path.Combine(basePath2, Thumbnail.FileName);
if (!System.IO.File.Exists(thumbnailPath))
{
using (var stream = new FileStream(thumbnailPath, FileMode.Create))
{
await Thumbnail.CopyToAsync(stream);
}
}
I am saving this model to the database:
var fileModel = new FileUploadViewModel
{
Year = createdOn,
PublishedOn = model.PublishedOn,
FileType = File.ContentType,
Extension = extension,
Name = model.Name,
Description = model.Description,
FilePath = filePath,
Author = model.Author,
ThumbnailPath = thumbnailPath,
};
When I want to show the thumbnail in a view, it doesn't work but in src I have the right path, as you can see in this screenshot:
Screenshot with Source of image
In controller :
string uniqueThumbName = null;
if (Thumbnail != null)
{
string uploadsFolder = Path.Combine(hostingEnvironment.WebRootPath, "Thumbnails");
uniqueThumbName=Guid.NewGuid().ToString() + "_" + Thumbnail.FileName;
string filePath2 = Path.Combine(uploadsFolder, uniqueThumbName);
Thumbnail.CopyTo(new FileStream(filePath2, FileMode.Create));
}
var fileModel = new FileUploadViewModel
{
ThumbnailPath=uniqueThumbName,
};
In View :
var thumbPath = "~/Thumbnails/" + file.ThumbnailPath;
<img style="width:80px;height:80px;" src="#thumbPath" asp-append-version="true" />
I have two action methods in my Controller class:
DetailsAll: to get some data and display in the view
SaveAsPDF: Called on windows.load of DetailsAll.cshtml which should save DetailsAll view as pdf
My issue is in SaveAsPDF Action method. Here I am trying to use Rotativa ActionAsPdf and subsequently BuildFile methods to generate and save the PDF. However, when executing the line "BuildFile", it is not hitting the breakpoint in my DetailsAll Action method, subsequently causing the PDF to be generated blank.
Could you please help where I am going wrong?
[HttpGet]
public ActionResult DetailsAll()
{
var selectionBuilder = builderFactory.GetGeocodeReportSelectionViewModelBuilder();
var companyList = selectionBuilder.Build();
List<GeocodeReportViewModel> viewModel = new List<GeocodeReportViewModel>();
foreach(SelectListItem record in companyList.Companies)
{
var builder = builderFactory.GetGeocodeReportViewModelBuilder(int.Parse(record.Value));
viewModel.Add(builder.Build());
}
var model = new AllGeocodeReportViewModel
{
GeocodeReports = viewModel
};
return View(model);
}
[HttpGet]
public string SaveAsPDF()
{
var report = new ActionAsPdf("DetailsAll")
{
FileName = "OEM_GeocodeReport_" + System.DateTime.Now.ToString("MMYY") + ".pdf",
PageSize = Size.A4,
PageOrientation = Orientation.Landscape,
PageMargins = { Left = 1, Right = 1 }
};
byte[] pdf = report.BuildFile(ControllerContext);
System.IO.File.WriteAllBytes("C:\\" + report.FileName, pdf);
return "true";
}
Finally found the issue after extensive search. I need to send Authentication cookies along with the BuildFile request for this to work. Added the below code and it generates PDF correctly now:
public void SaveAsPDF()
{
var cookies = Request.Cookies.AllKeys.ToDictionary(k => k, k => Request.Cookies[k].Value);
var report = new ActionAsPdf("DetailsAll")
{
FileName = "OEM_GeocodeReport_" + System.DateTime.Now.ToString("MMyy") + ".pdf",
PageSize = Size.A4,
PageOrientation = Orientation.Portrait,
PageMargins = { Left = 3, Right = 3 },
FormsAuthenticationCookieName = System.Web.Security.FormsAuthentication.FormsCookieName,
Cookies = cookies
};
byte[] pdf = report.BuildFile(ControllerContext);
System.IO.File.WriteAllBytes("C:\\" + report.FileName, pdf);
}
Code:
for (int i = 1; i < butonsayisi; i++)
{
int buttonvalue = 1;
var buttonmenu = new Button
{
HeightRequest = 100,
WidthRequest = 100,
Margin = 5,
CornerRadius = 15,
BackgroundColor = Color.FromRgb(192,192,192),
};
buttonmenu.Clicked += butonmenu;
butonlar.Children.Add(buttonmenu);
if (baglanti.State.ToString() == "Open")
{
}
else
{
baglanti.Open();
}
SqlCommand getir = new SqlCommand("select * from butonlar where id = '" + i.ToString() + "'", baglanti);
SqlDataReader oku = getir.ExecuteReader();
while (oku.Read())
{
buttonmenu.Text = oku.GetValue(1).ToString();
baglanti.Close();
break;
}
async void butonmenu(object o, EventArgs args)
{
baglanti.Open();
SqlCommand getirici = new SqlCommand("select * from butonlar where id = '" + buttonvalue.ToString() + "'", baglanti);
SqlDataReader okuyucu = getirici.ExecuteReader();
while (okuyucu.Read())
{
butonadi = okuyucu.GetValue(2).ToString();
baglanti.Close();
break;
}
await DisplayAlert("Alert","Deneme " + butonadi,"OK");
buttonvalue++;
}
}
I have to reach the right buttonvalue.
butonsayisi counts how much row I have in database, this is how I create buttons and after that I edit the name of buttons with buttonmenu.Text = oku.GetValue(1).ToString(); in index 1 I have the the name of buttons.
So in index 2 I have another table name. When I press the button, I have to get the right table name. With this method I use, I am taking another button's index 2.
await DisplayAlert("Alert","Deneme " + butonadi,"OK"); is just for testing.
i did it guys!
simply i did;
SqlCommand getirici = new SqlCommand("select * from butonlar where butonadi = '" + buttonmenu.Text + "'", baglanti);
SqlDataReader okuyucu = getirici.ExecuteReader();
while (okuyucu.Read())
{
butonadi = okuyucu.GetValue(2).ToString();
baglanti.Close();
break;
}
i used to get the value from id now i get from name of button so it works!
I am creating combobox in a component Column in a GridPanel from codebehind. There is requirement to create a store and filter its content according to some condition and bind it to the created combobox. Store is getting bind to combo but filter is not working. Please help me to get the proper solution for this. My code snippet is given below.
List<object> storeDataProductClass= new List<object>();
storeDataProductClass.Add(new { text = "Class0", value = "Class0", productIndex = 0});
storeDataProductClass.Add(new { text = "Class1", value = "Class1", productIndex = 1});
storeDataProductClass.Add(new { text = "Class2", value = "Class2", productIndex = 2});
storeDataProductClass.Add(new { text = "Class3", value = "Class3", productIndex = 3});
storeDataProductClass.Add(new { text = "Class4", value = "Class4", productIndex = 4});
Ext.Net.ComboBox cmbClass = new ComboBox();
cmbClass.ID = "cmbClass_" + i;
Model classModel = new Model();
classModel.Fields.Add(new ModelField("text", ModelFieldType.String));
classModel.Fields.Add(new ModelField("value", ModelFieldType.String));
classModel.Fields.Add(new ModelField("productIndex", ModelFieldType.Int));
Ext.Net.Store storeClass = new Ext.Net.Store();
storeClass.ID = "storeClass_" + i;
storeClass.AutoDataBind = true;
storeClass.Model.Add(classModel);
storeClass.DataSource = storeDataProductClass;
storeClass.DataBind();
storeClass.Filter("productIndex", i.ToString());
cmbClass.Store.Add(storeClass);
cmbClass.DisplayField = "text";
cmbClass.ValueField = "value";
compColumn.Component.Add(cmbClass);
I am using uploadify for uploading multiple images with progress in ASP.NET MVC3 and I want to upload lets say from url Gallery/Upload/2 to folder with name 2 and Gallery/Upload/3 to folder 3 and so on. I just don´t know how. For get working uploading I used this sample and modified sample upload script to this:
public string Upload(HttpPostedFileBase fileData)
{
var id = 2;
var fotka = new Photo();
fotka.GalleryId = id;
fotka.Description = fileData.FileName;
fotka.Name = fileData.FileName;
db.Photos.Add(fotka);
db.SaveChanges();
var fileNameWithoutExtension = Path.GetFileNameWithoutExtension(fileData.FileName);
var fileName = Path.GetFileName(fileData.FileName);
string path = Server.MapPath("~/Fotky/") + id.ToString() + "\\" + fileNameWithoutExtension;
// var path = Path.Combine(Server.MapPath("~/Fotky/"), galleryId.ToString(), "/", fileNameWithoutExtension);
using (var input = new Bitmap(fileData.InputStream))
{
int width;
int height;
if (input.Width > input.Height)
{
width = 128;
height = 128 * input.Height / input.Width;
}
else
{
height = 128;
width = 128 * input.Width / input.Height;
}
using (var thumb = new Bitmap(width, height))
using (var graphic = Graphics.FromImage(thumb))
{
graphic.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
graphic.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
graphic.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighQuality;
graphic.DrawImage(input, 0, 0, width, height);
System.IO.Directory.CreateDirectory(Server.MapPath("~/Fotky/") + id.ToString());
using (var output = System.IO.File.Create(path + "_small" + Path.GetExtension(fileName)))
{
thumb.Save(output, System.Drawing.Imaging.ImageFormat.Jpeg);
}
}
}
fileData.SaveAs(path + Path.GetExtension(fileName));
return "ok";
}
as you can see I am using id as 2 as default, but I want to get it from parameters, is it posible? And how? Thank you
No one knows answer? It´s really important for me
You could have your controller action take the id as action argument:
public string Upload(HttpPostedFileBase fileData, string id)
{
...
}
and then pass this id when configuring your plugin:
$("#fileuploader").fileUpload({
'uploader': '#Url.Content("~/Scripts/uploader.swf")',
'cancelImg': '#Url.Content("~/Images/cancel.png")',
'buttonText': 'Select Image',
'script': '#Url.Action("Upload", "Home", new { id = "2" })',
'folder': '#Url.Content("~/uploads")',
'fileDesc': 'Image Files',
'fileExt': '*.jpg;*.jpeg;*.gif;*.png',
'multi': true,
'auto': true
});
