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! :)

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:)
