I recently created a copy of Northwind database and called it NorthwindBootstrap. This database has a built-in membership tables added to it. The copy includes both of mdf and ldf files. My next step is to create a new database based from the recently copied/renamed files in which I have no idea on how to do it. After doing some research, I stumbled upon a t-sql script based from my requirement. USE [master] GO CREATE DATABASE [NorthwindBootstrap] ON ( FILENAME = N 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\NorthwindBootstrap.mdf' ), ( FILENAME = N 'C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\NorthwindBootstrap.ldf' ) FOR ATTACH GO Cheers! :)

Based from the issue, the fix is to check the database field against the view model class. In my case, the database field is smallint (nullable). So, the fix is to change the model code from int datatype: public int? StockOnHand { get ; set ; } To Int16 datatype: public Int16? UnitsInStock { get ; set ; } :-)

Here's what I did in order to recognize the draggable function in one of my asp.net mvc page. 1. Add jquery-ui.js to scripts folder. 2. Bundle the js file in BundleConfig.cs 3. Render the bundled script in _Layout.cshtml. Cheers! :-)

Hello, In order for the jQuery intellisense to work in Visual Studio 2013, perform the following steps. 1. Proceed by clicking Tools -> Options -> Text Editor -> JavaScript -> Intellisense -> References. 2. Change Reference Group to Implicit (Web)   By default a reference has been added to _references.js. If not, add a new reference file under Scripts folder. 3. Open _references.js file using your Visual Studio IDE or any text editor software. 4. Add reference path to jquery files (.js, .min.js, and .intellisense.js). 5. Close Visual Studio and Open it again. (I was struggling for hours as to why performing steps 1 through 4 didn't work. This step fixed the issue) Reference: jQuery intellisense not working in VS 2012 Regards, :)

Hello, When retrieving records by joining two tables wherein the foreign key of the referenced table is a nullable column, and you want to return all records from the primary table, with or without the matching rows in the right table, the query would be using left join rather than inner join. So in LINQ expression, rather than inner join, revise the query to left join as presented below. Show products with matching categories, disregarding other products without categories MVC View: Code: 1 2 3 4 5 6 7 8 9 10 11 model.Products .AddRange( ( from item in context.Products .Where(item => item.Name.Trim().StartsWith(selectedLetter)) join category in context.ProductSubcategories on item.ProductSubcategoryID equals category.ProductSubcategoryID select new ProductModel() { ProductName = item.Name, ProductID = item.ProductID, ProductNumber = item.ProductNumber, Color = ( string .IsNullOrEmpty(item.Color)) ? "NA" : item.Color, St...

Here's how to show tooltip in an asp.net gridview column/cell on mouse hover. This option will set the Tooltip property of a particular gridview cell on RowDataBound event. C# Code: 1 2 3 4 5 6 7 8 protected void grdCustomers_RowDataBound( object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { string str = e.Row.Cells[1].Text; e.Row.Cells[1].ToolTip = str; } }

As I was creating a simple Create, Update, Delete (CRUD) application in ASP.NET MVC 5 and executing the controller on Edit, I encountered an error called "Store update, insert, or delete statement affected an unexpected number of rows (0)". After debugging and looking at the stack trace, I found out that the value of the primary key is zero. Department: "Education" Designation: "Dean" EmployeeName: "JE" EmployeeID: 0 Salary: 25500 The fix for this issue is to add a hidden field to the edit view referencing to the primary key which in this case is the EmployeeID. @Html.HiddenFor(model => model.EmployeeID) And now, the model passed to the context now has a value for the EmployeeID field. Department: "Education" Designation: "Dean" EmployeeName: "JE" EmployeeID: 2 Salary: 25500 Cheers! :)

Hi, Recently, I have encountered an issue on how to reset cascading dropdown controls in cross browsing mode (IE/Firefox/Chrome) using JavaScript and jQuery.

Good day! After migrating and then rebuilding the solution of a Windows Forms application from Windows XP machine to Windows 8, I encountered an error as stated on the title of this post. I suspect this has something to do with the old version from the XP machine not recognized on the new machine. The steps to fix this issue are provided below: 1. Download Microsoft Visual Basic Power Packs 3.0 here: Microsoft Visual Basic Power Packs 3.0 2. Remove the previous Microsoft Visual Basic Power Packs under References in your project 3. Add the MS Power Pack version 3.0 as reference to your project from the default installation folder located here: C:\Program Files (x86)\Microsoft Visual Basic 2005 Power Packs\3.0 4. Rebuild your project. Greg Esguerra:)

Good evening! The solution I found so far for this issue "There is a duplicate scriptResourceHandler section defined (HTTP Error 500.19)" was to change the Application Pool of the website from DefaultAppPool to .NET v2.0. I also have tried with no luck other solutions based from stackoverflow. Issue Fix Details Operating System: Windows 8 IIS: Version 8 Default Site Framework: .NET 3.5 SP1 Reference: There is a duplicate scriptResourceHandler section defined

I have an .msi file created using .NET Framework 3.5 SP1 in which it can't proceed to installation as stated by the title of this post. Since I'm running on IIS 8, there might be some issues communicating with IIS 6. Taken from the point that this application was packaged using Visual Studio 2008. The fix is to enable IIS Metabase and IIS 6 configuration compatibility through the Control Panel -> Turn Features On/Off. Details OS: Windows 8 IIS: 8 .NET Framework: 3.5 SPI Visual Studio: 2008

Hello, Right clicking an MSI file through Windows 8 and then "Run As Administrator" isn't supported. After doing some research, I found some steps to achieve it. See instructions below: 1. Start Button / key 2. Type in "cmd" without quotes and press Shift+Enter to open a command prompt as an administrator. 3. Type in the full path to the msi and press enter. Put the path inside quotes if it has any spaces like "C:\Users\username\My Documents\SoftwarePackage.msi" 4. Press enter and agree to execute the MSI See Reference here: Run an MSI file as Administrator

Hello, While trying to add Unity to a Console Project, I encountered an error as stated by the title of this post. After doing some research, I found a post in Stack Overflow which is to update Nuget Package Manager. When I checked my VS, the nuget package manager is an older version. So, I removed/uninstalled it and added the recent version of Nuget package manager through Tools -> Exentsion and Updates then look for Nuget Package Manager. Then install/download it in your VS IDE. See image for current Nuget Package Manager. That's It.. :)

Good evening! Normally, the css snippet below paints a transparent border to containers or divs using Mozilla Firefox, Chrome or IE9+. .NewsContent { background-color : #fff; border : 10px solid transparent ; background - clip : content -box; } However, for other IE8 and below, I had a hard time figuring out how to make the border transparent. Luckily, I found a link: Border Color Transparent in IE6 which serves as the basis on how to set transparent border color in Internet Explorer 8 and below using CSS below: .NewsContent { background-color : #fff; border : 10px solid black; filter: chroma( color =black); } Afterwards, the border color changed to transparent.
