#Visual studio data generator generator
This class inherits from the base Generator class (all generators should inherit from this class or implement the IGenerator interface - trust me, using this class is the easiest). Add this class to your solution (see SequentialDataBoundGenerator.cs in the code download). The heavy-lifting class is the SequentialDataBoundGenerator. The code pulls the column information out for display in the drop-down list. Each returned row represents a column in the schema. For the purpose of the DBG, the GetOutputs method retrieves the schema returned by the select statement (because you need to be able to choose the correct column of data to bind to in the designer). This method returns the information displayed in the designer. The GetOutputs method is more complicated. In this case, the code is simply checking to ensure the Connection Info and Select Statement are stored. The OnInputValueChanged method is called whenever an input to your generator is changed (these inputs are decorated with the InputAttribute discussed later in this column). You have to override two key methods in this class - the OnInputValueChanged method and the GetOutputs method. This class inherits from the base DefaultGeneratorDesigner, which simplifies things for you. Reference the class file named "SequentialGeneratorDesigner.cs" in the code download. Rename Class1 to SequentialGeneratorDesigner. Create a new C# Class Library project called CustomDataGenerators. Start building your DBG by creating the designer. The designer shows up in the drop-down list in the column details window (see Figure 1). You have to create not only the DBG, but also the Data Bound Generator Designer. The generator has some other limitations because of space, but you can modify this to suit your needs.Ī data-bound generator is a bit more complicated than a standard generator because you don't know the output ahead of time. This generator is almost identical to the one that comes with DB Pros except for one difference - it reads data sequentially (and you'll find it easy to update to allow the user to select between sequential or random). You can download the solution code associated with this column (it's available in both C# and VB).
