Topic: Storing Dialog or Forms settings with UserConfigurationManager

[Jeff H]

Sorry if this has been covered and I have not used it enough to know if it is a good long term solution, but here is one way to store settings that will remain between opening and closing and between sessions.
 
Say you have a form with a Checkbox and TextBox

 
The methods of IConfigurationSection  to retrieve and store the settings are

Code - C#: [Select]

1.     object ReadProperty(string name, object defaultValue);
2.     void WriteProperty(string name, object value);
3.  

ReadProperty takes the a name it was stored with and a default property if it is not found.
WriteProperty takes the name to store it with and the value to store.
Here is one way to use it

Code - C#: [Select]

1.     public partial class Form1 : Form
2.     {
3.         public Form1()
4.         {
5.             InitializeComponent();
6.         }
7.         private void Form1_Load(object sender, EventArgs e)
8.         {
9.             UserConfigurationManager mng = Autodesk.AutoCAD.ApplicationServices.Application.UserConfigurationManager;
10.             using (IConfigurationSection sesction = mng.OpenDialogSection(this))
11.             {
12.                 if (sesction != null)
13.                 {
14.                     checkBox1.Checked = (bool)sesction.ReadProperty("IsChecked", false);
15.                     textBox1.Text = (string)sesction.ReadProperty("SearchText", "");
16.                 }
17.             }
18.         }
19.         private void Form1_FormClosed(object sender, FormClosedEventArgs e)
20.         {
21.             UserConfigurationManager mng = Autodesk.AutoCAD.ApplicationServices.Application.UserConfigurationManager;
22.             using (IConfigurationSection sesction = mng.OpenDialogSection(this))
23.             {
24.                 sesction.WriteProperty("IsChecked", checkBox1.Checked);
25.                 sesction.WriteProperty("SearchText", textBox1.Text);
26.             }
27.         }
28.     }
29.  

*************************Edit***********************
Of course needs to be opened through Application object

Code - C#: [Select]

1.         [CommandMethod("TestForm", CommandFlags.Modal)]
2.         public void TestForm() // This method can have any name
3.         {
4.             Form1 frm = new Form1();
5.             Application.ShowModalDialog(frm);
6.         }
7.

You can do that without having to write any code. 

Select a control on your form (or with nothing selected to create a setting for the form itself), and in the Properties tool window, expand the first item (ApplicationSettings). Then select (PropertyBindings), and click the button to the right.  In the dialog, enter a name for the setting, and the value.

In the case of a standalone executable, you're done. In the case of a form used in AutoCAD, you have to manually save the settings when the form is closing, which you can do using the Properties.Settings class created by the designer:

Code - C#: [Select]

1.  
2.     Properties.Settings.Default.Save();
3.  
4.  

The Settings class can also be manipulated manually, or modified to have additional settings that don't correspond to a Component. You'll find it in the Properties node of your project in Solution Explorer.

Thanks Tony,
That is how I normally do it, but would add a Settings File and did not know about adding the properties through the properties window.
