If you actually go to SQL Server Express and see the rows in the demotb table, you will see the row was successfully deleted as shown below. We also saw how we read each row of the table and use a messagebox to display the contents of a table to the user. From the above data structure, the user would ideally want to see the TutorialID and Tutorial Name displayed in a textbox.
Secondly, they might want to have some sort of button control which could allow them to go to the next record or to the previous record in the table. The good news is that C can reduce the additional coding effort by allowing binding of controls to data.
What this means is that C can automatically populate the value of the textbox as per a particular field of the table. So, you can have 2 textboxes in a windows form. You can then link one text box to the TutorialID field and another textbox to the TutorialName field.
Visual Studio will ensure that it writes the code for you to ensure the linkage works. Then when you run your application, the textbox controls will automatically connect to the database, fetch the data and display it in the textbox controls. In our example, we are going to create 2 textboxes on the windows form. Step 1 Construct the basic form. In the form drag and drop 2 components- labels and textboxes. Then carry out the following substeps.
Step 2 The next step is to add a binding Navigator to the form. The binding Navigator control can automatically navigate through each row of the table. To add the binding navigator, just go to the toolbox and drag it to the form. Step 3 The next step is to add a binding to our database.
The Binding Navigator is used to establish a link from your application to a database. When you perform this step, Visual Studio will automatically add the required code to the application to make sure the application is linked to the database.
So to ensure the connection is established between the application and the database, the first step is to create a project data source.
The following screen will show up. When you click on the project data source, you will be presented with a wizard; this will allow you to define the database connection. Step 4 Once you click on the Add Project Data Source link, you will be presented with a wizard which will be used to create a connection to the demotb database.
The following steps show in detail what needs to be configured during each step of the wizard. When you click the Finish button, Visual Studio will now ensure that the application can query all the rows in the table Demotb. Step 5 Now that the data source is defined, we now need to connect the TutorialID and TutorialName textbox to the demotb table.
When you click on the Text property of either the TutorialID or TutorialName textbox, you will now see that the binding source to Demotb is available. For the first text box choose the Tutorial ID.
Repeat this step for the second textbox and choose the field as TutorialName. The below steps shows how we can navigate to each control and change the binding accordingly. The reason we do this is that the Binding Navigator also needs to know which table it needs to refer to.
