This section outlines the steps for step 3 of the 1stGrid tutorial. Step 3 adds a property grid to the application, allowing the properties of a grid control to be configured at run-time.
If you don't want to keep Step 2, then skip to Section 8.4.2 to continue adding the Step 3 features to Step 2.

From the context menu that appears, select Add | New Project.
Click Visual C# Projects.

Set the Name to "Step 3".
Click OK.
Right click and delete AssemblyInfo.cs and Form1.cs.
From the command prompt or from the Windows Explorer:
Delete all of the remaining Step 3 project and source files.
Copy all of the Step 2 source and project files into the Step 3 directory.
Rename Step 2.* to Step 3.*.
Visual Studio displays a message that the project has changed. Select Discard to discard any cached Step 3 project files.

From the context menu that appears, select Set As Startup Project.
The following steps create a new form for displaying the property grid.

Drag a button from the Toolbox onto the form. Position as desired.
Set the properties for the button.

Add the implementation for the Click event.
View the events for the button by clicking the lightning bolt in the property grid.
Double-click the Click event.
Add the following implementation for the event:
this.Close(); |
View the source code for the form (use the View|Code Visual Studio menu option).
Add a constructor argument of type Stingray.Grid.GridControl.
After the comment "TODO: Add any constructor code after InitializeComponent call", add a command to set the selected object for the property grid to the grid given to the constructor.
public GridProperties(Stingray.Grid.GridControl grid)
{
//
// Required for Windows Form Designer support
//
InitializeComponent();
//
// TODO: Add any constructor code after InitializeComponent call
//
propertyGrid1.SelectedObject = grid;
}
