Hello friends,
I have 5 lac (or more in future) Data to access in my asp.net webform.
Currently using GridView with Custom Paging with repeater control.
Note : my codes are based on this :-
[^]
private void BindPager(int totalRecordCount, int currentPageIndex, int pageSize)
{
double getPageCount = (double)((decimal)totalRecordCount / (decimal)pageSize);
int pageCount = (int)Math.Ceiling(getPageCount);
List<ListItem> pages = new List<ListItem>();
if (pageCount > 1)
{
pages.Add(new ListItem("FIRST", "1", currentPageIndex > 1));
for (int i = 1; i <= pageCount; i++)
{
if (i == 1)
{
pages.Add(new ListItem(i.ToString(), i.ToString(), i != currentPageIndex ));
}
else
{
pages.Add(new ListItem(i.ToString(), i.ToString(), i != currentPageIndex + 1));
}
}
pages.Add(new ListItem("LAST", pageCount.ToString(), currentPageIndex < pageCount - 1));
}
rptPager.DataSource = pages;
rptPager.DataBind();
}
But this
=>code is not functioning well for page no "1" and "First" option.
=>It generates around 10,000 (Page No) links if my page size is 50 records/page, which is look too odd.
=>facing sorting issue with this.
Can anyone tell me solution for the above or give me some alternative.

Hi guys.
I have a question regarding the learning path for ASP.net. I have a fundamentals of C# and basic experience with creating apps for windows 8 and UWP apps. I know some basics of java-script and can create static websites. Now I want to start creating web sites including back-end. I want create something where a user can register, login, have a profile, make a payment and so on.
The thing is that I am quite confused about this topic and cannot find a clear answer.
I hear the terms like ASP.NET, ASP.NET 5, ASP.NET MVC, ASP.NET CORE, ASP.NET MVC CORE etc.
So now, when I am trying to find and online course I don't know what to learn first and what not to learn because its old and not worth it.
If you could guys point me in the right direction on what to learn and what order to be atcheive my goal would be great. Any suggestions about any specific course would be appreciated.
Tanks in advance.

ASP.NET Core is the "new shiny", which is getting almost all of Microsoft's love these days.
ASP.NET MVC Core doesn't exist as a separate thing; it's just a part of ASP.NET Core.
Anything that isn't "Core" typically comes under the ASP.NET umbrella. "Web Forms" is the oldest ASP.NET technology, and should generally be avoided for new development wherever possible. MVC and WebAPI were bolted on later; they generally result in much cleaner code, and were the starting point for ASP.NET Core.

I have a Tablix, and you go to Tablix properties and choose Sorting,
And of course you can add Field values to the sort order.
On the 2nd Sort Order, I need a custom expression, which sorts by Company Name or Sales Totals based on a Parameter;
"N" stands for Company Name, "T" stands for Sales Total
thus
=iif(Parameters!sortOrder.Value = "N", Fields!FCOMPANY.Value, Fields!FCSAMT.Value)
But if I sort on Sales Totals, I need the highest first, then lowest; Z-A
My expression works fine for Company Name: A-Z
But I couldn't find any references on the web for sort order.
If it ain't broke don't fix it

Maybe you have to make 2 filters for this, and can't do it in one, and use the button to select the order.
Well I did that and it works. Just thought I could do it in 1 expresion
If it ain't broke don't fix it

I am trying to build a dictionary of RedirectToRouteResults.
Background:
I am building a web application. Once a user gets past the login, the server returns an encrypted session cookie that follows the user around and is used to display user specific information on each page. Pretty standard fair. Now, the problem is that each Controller Action performs a check on the cookie to check for tampering, if the user's session has expired, if the user is authorized for this page, etc... so each controller has to handle a half-dozen different return types from the security check function. I could handle this with a switch...case in the catch block of each controller's code but that seems sloppy.
The Question:
I am having trouble figuring out how I can build a Dictionary of redirect routes to simplify this. I haven't been able to find anything on the internet in the way of an example for properly building a RedirectToRouteResult object that can be returned in a controller.
Instead of this:
public ActionResult Index()
{
SecurityCheck secCheck = ValidateConnection(this);
if (secCheck != secCheck.Okay)
{
switch (secCheck)
{
case SecurityCheck.AuthenticationFailure:
return RedirectToAction("Default", "ErrorHandler", new { message = "Not Authorized." });
}
}
}
I would like to simplify it to:
public ActionResult Index()
{
SecurityCheck secCheck = ValidateConnection(this);
if (secCheck != secCheck.Okay)
{
return SecurityRedirect.Routes[secCheck];
}
else
{
return View();
}
}
Is there a way? I am having no luck figuring out how to build a RedirectToRouteResult as the documentation on it is Spartan at best. I do believe that they would accomplish my goal.

Sounds like you want an action filter[^] instead.

Is it possible to pass an object created by an authorization filter to the controller action? My authentication processing creates several objects that get used by most controller actions.

Something like this[^] should work. If you add the data to the filterContext.RouteData.Values collection with a specific key, you should be able to receive it as a parameter to your action, where the parameter name matches the key.

I ended up wrapping the Controller class in a wrapper class with Properties for the data that I needed to pass along. Problem solved.

Okay, so I have made some progress but I am running into a bit of trouble. On a lot of failures, I redirect the user to the login page but the page URL is not being populated so it tries to call my login action on whatever page its on resulting in an error.
private ViewResult GetRedirectToLogin()
{
ViewResult result = new ViewResult();
result.ViewName = "~/Views/Login/Index.cshtml";
result.MasterName = "~/Views/Shared/_loginlayout.cshtml";
result.TempData = _context.Controller.TempData;
return result;
}
This has been working. Any errors with authentication are caught and the user is redirected. The problem is that the browser still thinks its on the first page so that when I click my "Login" button the server looks for a [HttpPost]Login action and returns a 404 error.
if (Object.DividedByZero == true) { Universe.Implode(); }

How about:
private ActionResult GetRedirectToLogin()
{
return new RedirectToRouteResult(new RouteValueDictionary
{
{ "Controller", "Login" },
{ "Action", "Index" }
});
}

I found that one. Works like a charm. Thanks for your help on this one. I had never even looked at Action Filters before this.

I have an ASP.Net application built in Visual Studio 2015 and deployed to the Azure environment. I am trying to add the capability to allow the user to reset their password. The application sends an email to the user with a link that contains a code to validate the user. After clicking on the link, the user is sent to a page that allows them to enter a new password then click a Submit button to actually change the password. This works fine in the Visual Studio environment but fails with no indication of why after being deployed to Azure. Does anyone have an idea of what might cause this?
The original page is displayed correctly and the code is validated. The process fails when the user clicks the submit button and the standard login page is displayed.
Thanks.
Phil

How can anyone guess with only that information Quote: fails with no indication of why
You must be able to do some kind of debugging to track down the point of failure: is the token not being read? Is it being found in the database? Is a matching user record found? Is the database read or write the issue? There are numerous places in the process you can monitor to see what's going on. If nothing else, log every step along the way...

The token works fine and the user record is found. Those items are checked before the page is displayed that allows the user to enter a new password. It fails when it tries to submit the information. I do not have remote debugging capability so the best I can do is try to display error messages but none of them are displayed.
Code is included below:
@using Microsoft.AspNet.Identity;
@model CLCC_Browser.Models.ManageResetViewModel
@{
ViewBag.Title = "Password Reset";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@ViewBag.Title.
@using (Html.BeginForm("ManageReset", "Account", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary()
@Html.HiddenFor(m => m.Token, new { @class = "form-control" })
@Html.HiddenFor(m => m.UserID, new { @class = "form-control" })
}
[AllowAnonymous]
public async Task<actionresult> ManageReset(string userName, string userId, string code)
{
IdentityResult result;
ManageResetViewModel model = new ManageResetViewModel();
var provider = new DpapiDataProtectionProvider("PokerResults");
UserManager.UserTokenProvider = new DataProtectorTokenProvider<applicationuser>(provider.Create("ResetPassword"));
UserManager.FindById(userId);
try
{
result = await UserManager.ConfirmEmailAsync(userId, testcode);
}
catch (InvalidOperationException ioe)
{
// ConfirmEmailAsync throws when the userId is not found.
ViewBag.errorMessage = ioe.Message;
return View("Error");
}
if (userId == null || code == null)
{
return View("Error");
}
ViewBag.HasLocalPassword = false;
ViewBag.UserID = userId;
model.UserName = userName;
model.UserID = userId;
model.Token = code;
return View(model);
}
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<actionresult> ManageReset(ManageResetViewModel model)
{
IdentityResult result;
var provider = new DpapiDataProtectionProvider("PokerResults");
UserManager.UserTokenProvider = new DataProtectorTokenProvider<applicationuser>(provider.Create("ResetPassword"));
string thetoken = await UserManager.UserTokenProvider.GenerateAsync("ResetPassword", UserManager,
UserManager.FindByName(model.UserName));
model.Token = thetoken;
ModelState state = ModelState["NewPassword"];
if (state != null)
{
state.Errors.Clear();
}
if (ModelState.IsValid)
{
// result = await UserManager.AddPasswordAsync(User.Identity.GetUserId(), model.NewPassword);
result = await UserManager.ResetPasswordAsync(model.UserID, thetoken, model.NewPassword);
if (result.Succeeded)
{
ModelState.AddModelError("", "Password Reset Succeeded.");
Response.Write("alert('Password Updated');");
ViewBag.Message = "Password Reset Successful";
ViewBag.ResetType = "Complete";
Session["ResetStatus"] = "Complete";
return RedirectToAction("ResetPassword", "Account", "Complete");
// return RedirectToAction("Manage", new { Message = ManageMessageId.SetPasswordSuccess });
}
else
{
ModelState.AddModelError("", "Password Update failed, User = " + model.UserID);
Response.Write("alert('Password Update failed');");
AddErrors(result);
}
}
else
{
ModelState.AddModelError("", "Password Update failed");
Response.Write("alert('Password Update failed - Invalid Model');");
}
return View(model);
}

Hi again,
This is part of our ongoing dynamic row creation in Repeater.
By default, the first row is available.
After filling in data into the cells of the first row, user clicks the Add New Row button to add another row.
This part works fine.
The issue is that whether user enters one row or several rows, when you submit the data to the database, only one row of data is saved.
Here is the code that I am using.
Any ideas how to modify this so that no matter how many rows are created in the markup, those rows are saved to the database.
Thanks in advance.
foreach (DataRow row in table.Rows)
{
string txBoatRegNum = row.ItemArray[1] as string;
string txTaxPayerRet = row.ItemArray[2] as string;
if (txBoatRegNum != null & txTaxPayerRet != null)
{
if (string.IsNullOrEmpty(txTaxPayerRet))
{
txTaxPayerRet = "0";
}
SqlCommand aircmd = new SqlCommand("sp_savetInfo", conn);
aircmd.CommandType = CommandType.StoredProcedure;
aircmd.Parameters.AddWithValue("@pid", accountnumber.Text);
aircmd.Parameters.AddWithValue("@eID", Request["pageId"]);
aircmd.Parameters.AddWithValue("@txYr", txtTaxYr.Text);
aircmd.Parameters.AddWithValue("@regno", txBoatRegNum);
aircmd.Parameters.Add("@txretval", SqlDbType.Money).Value = decimal.Parse(txTaxPayerRet);
aircmd.ExecuteNonQuery();
lblResult.ForeColor = System.Drawing.Color.Green;
lblResult.Text = "Thank you! <br>You have successfully completed the form.";
lblResult.ForeColor = System.Drawing.Color.Red;
lblResult.Text = "Your form failed to save, please try again.";
}
}

What happens when you step through the code in the debugger?
|
|
|
|
|
You need to debug it and see what is happening. We don't know what table.Rows is or what is in it so there is little we can do to help.
There are two kinds of people in the world: those who can extrapolate from incomplete data.
There are only 10 types of people in the world, those who understand binary and those who don't.
