Now, the single employee record returned from GetEmployee() is displayed in another rich data control the DetailsView. By default, the DetailsView creates a basic table with one row for each field or property in the data item. Here s a basic declaration for the DetailsView: <asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="True"/> You have one more detail to fill in. The first time the page is requested, there won t be any selected value in the lstEmployees control. However, the DetailsView will still try to bind itself, so the ObjectDataSource will call GetEmployee(). The employeeID parameter is null, but the actual value that s passed is 0, because integers aren t nullable. When the GetEmployee() method executes the query, it doesn t find a matching record with an employeeID of 0. This is an error condition, and an exception is thrown. You could solve this problem by revising the GetEmployee() method to return null in this situation. However, it makes more sense to catch the binding attempt and explicitly cancel it when there s no employeeID parameter. You can do this by handling the ObjectDataSource.Selecting event and looking for the employeeID parameter in the ObjectDataSourceSelectingEventArgs.InputParameters collection, which has every parameter you re using indexed by name. protected void sourceEmployee_Selecting(object sender, ObjectDataSourceSelectingEventArgs e) { if (e.InputParameters["employeeID"] == null) e.Cancel = true; }

This dynamically generated piece of code will be executed every time the page is requested Here s the first part of the GetCodeExpression() method: public override CodeExpression GetCodeExpression(BoundPropertyEntry entry, object parsedData, ExpressionBuilderContext context) { // entryExpression is the number string // without the prefix (for example "1,6") if (!entryExpressionContains(",")) { throw new ArgumentException( "Must include two numbers separated by a comma"); } else { // Get the two numbers string[] numbers = entryExpressionSplit(','); if (numbersLength != 2) { throw new ArgumentException("Only include two numbers"); } else { int lowerLimit, upperLimit; if (Int32TryParse(numbers[0], out lowerLimit) && Int32TryParse(numbers[1], out upperLimit)) { .. So far, all the operations have been performed in normal code That s because the two numbers are specified as part of the expression.

How to generate data matrix 2d bar code for c# - MSDN - Microsoft
And I need to generate data matrix to name and phone and address .... You might want to interface with LibDmtx using DataMatrix . net .

The ObjectDataSource provides the same type of support for updatable data binding as the SqlDataSource. The first step is to specify the UpdateMethod, which needs to be a public instance method in the same class: <asp:ObjectDataSource ID="sourceEmployees" runat="server" TypeName="DatabaseComponent.EmployeeDB" SelectMethod="GetEmployees" UpdateMethod="UpdateEmployee" /> The challenge is in making sure the UpdateMethod has the right signature. As with the SqlDataSource, updates, inserts, and deletes automatically receive a collection of parameters from the linked data control. These parameters have the same names as the corresponding class properties. To understand how this works, it helps to consider a basic example. Assume you create a grid that shows a list of EmployeeDetails objects. You also add a column with edit links. When the user commits an edit, the GridView fills the ObjectDataSource.UpdateParameters collection with one parameter for each property of the EmployeeDetails class, including EmployeeID, FirstName, LastName, and TitleOfCourtesy. Then, the ObjectDataSource searches for a method named UpdateEmployee() in the EmployeeDB class. This method must have the same parameters, with the same names. That means this method is a match: public void UpdateEmployee(int employeeID, string firstName, string lastName, string titleOfCourtesy) { ... }

They won t change each time the page is requested, and so they don't need to be evaluated each time the page is requested However, the random number should be recalculated each time, so now you need to switch to CodeDOM and create a dynamic segment of code that performs this task The basic strategy is to construct a CodeExpression that calls the static GetRandomNumber() method..

Once you make your selection and click Open, Visual Studio returns you to the Create New Web Site dialog box. Click OK, and Visual Studio will create the new web application. A new website starts with a Default.aspx start page and its Default.aspx.vb code-behind file.

This method is not a match, because the names don t match exactly: public void UpdateEmployee(int id, string first, string last, string titleOfCourtesy) { ... } This is not a match, because there s an additional parameter: public void UpdateEmployee(int employeeID, string firstName, string lastName, string titleOfCourtesy, bool useOptimisticConcurrency) { ... } The method matching algorithm is not case-sensitive, and it doesn t consider the order or data type of the parameters. It simply tries to find a method with the right number of parameters and the same names. As long as that method is present, the update can be committed automatically, without any custom code.
