Can you let us know which method in master pages you have the code. Some methods execute only once and some executed every time. For example , PostBack do not go though all the methods in page lifecycle.
Is there any way that a reference to the master page can be setup uniquely for a single web page? If so, how would you setup that code?
Here is the code I am thinking you wanted to see:
Partial Class attendanceletters_default
Protected _master As MasterPage
Protected _schoolyear As Integer
#Region "Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load"
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
_master = CType(Page.Master, MasterPage)
_master.PageTitle = "Attendance"
Dim schoolDate As DateTime = Today()
Dim schoolMonth As Integer = schoolDate.Month
Dim schoolYear As Integer = schoolDate.Year
If schoolMonth >= 8 And schoolMonth <= 12 Then
_schoolyear = schoolDate.AddYears(1).Year
ElseIf schoolMonth >= 1 And schoolMonth <= 7 Then
_schoolyear = schoolDate.AddYears(0).Year
If Request.UrlReferrer IsNot Nothing Then
SiteUserManager.SessionUser.SiteUri = Request.UrlReferrer
If Not Page.IsPostBack Then
If (SiteUserManager.SessionUser IsNot Nothing) Then
If ddlSchools.SelectedValue <> "" Then
For the javacript alert message, I have the following questions:
1. At the top the alert message, it says 'Message from Web Page' since that is probably the default value. Is there a way that I can change this message to something I want? If so, how can I change the message?
2. I am wondering what if there maximum length that I can display in the error message? If so, what is the maximum length?
3. Can I extend the maximum size of the message and if so, can you show me how to extend the size of the error message?
4. Can I change the display icon to be an error instead of a warning? If so, how would I accomplish this goal?
2 & 3 None but if the message gets too big it is unreadable
Alert has no real use outside of debugging, if you want to show a "popup" or modal message then look at a jQuery plug-in for it. jQuery UI comes with one but there are many others if you google "jquery modal plug-in".
I want to add another something here to join the table below. In the RDLC using a Tablix, I can only have 1 dataset. If I create 2 datasets, the dataset prints after the data above, and is not part of the set above.
//Assign the dataSet to the Tablix in the report canvas body
Dim ds_CR As DataSet = New DataSet()
ds_CR.DataSetName = "ds_customerRecords"
ds_CR.Tables(0).TableName = "tablix_customerRecords"
//Write the datasource to the report canvas
rv_Canvas.LocalReport.DataSources.Add(New ReportDataSource("ds_customerRecords", ds_CR.Tables(0)))
As a caveat, I'm getting the data from an old Foxpro database that is not quite SQL
I have tried many steps like uninstall NuGet pakeged and than restart the Visual studio and than again i install the pakeges .
I have tried another solution which is
Press Windows + R
Enter appwiz.cpl and press Enter
Right-click the entry "Microsoft Visual Studio Express 2015 for Web" and click "Repair"
(This is going to reinstall all packages that you have uninstalled, because you weren't needing them (eg. Microsoft SQL Server Native Client)
You missed the point! I'm NOT your debugger - you have one built in in your VS!!!
With that attitude you will spend an eternity to solve such problems...
You want answers? Give details! We do not ask questions for nothing, but to help and clarify!!!

I have very perplexing issue. For years I have made websites with Asp.net and have used some lines of code to export gridview data to an excel work sheet. Last week the code just stopped working, I did not change anything with the code to any of the points in my website that exports to excel, it just stopped working.
I have tested it on both my development server and production server, same thing. It still pops up an excel link but when you open the excel file there is nothing, and it doesn't even generate a blank workbook.
The thing is, you're NOT exporting the grid to an Excel file. You're sending an HTML document to the browser, but "lying" in the headers and telling it the response is an Excel document. Excel is then doing its best to convert the HTML into an Excel worksheet.
Not only does this limit your control over the formatting and prevent you from using any "advanced" features of Excel, it also leaves you subject to the whims of whatever version of Excel the user has installed. When you run into strange problems like this, there is often no obvious cause or workaround.
If you're lucky, you might be able to track it down to a recent security update, or a change to the users' settings. But telling your users to uninstall security updates just to get your code working again isn't a sensible option.
You'll probably have better luck if you change your code to create a real Excel file. Since you're using ASP.NET, you can't use Office Interop[^]. But there are several open-source libraries which are safe to use from server-side code:
In my Relation i have two tables relation (one to many)
Id (primary key)
Id (primary key)
Countryid (forign key)
I have controller City have the following function
publicclass CityController : Controller
mytaskdbEntities db = new mytaskdbEntities();
// GET: Citypublic ActionResult List()
You can add button control with command 'delete' in the buttons. When you click pass the id of city to be deleted to the controller. In the controller you need to receive two parameters command and id of the city.
What's your issue ?
