Resolved DataGridView Settings

[amnon]

Hello,
So far, I have stored the DataGridView settings like DataGridViewAutoSizeColumnsMode in the application settings (My.Settings), but I would like to be able to change and save them depending on the user. Could you give me some tips, I was thinking of creating xml file and storing these settings threre, and loading them at startup.

Best Regards
amnon

You could also consider writing that info to the registry, but an XML or even a JSON file would work nicely.

I created a sample program with two forms. On the first form I have DataGridView with button "DataGridView settings", which loads form2. On Form 2 I have check boxes responsible for DataGridView settings and one button "save setiings" which save all settings. Maybe it will be useful to someone.

Form 1 - Load

        If My.Settings.MyAllowUserToResizeColumns = True Then
            DataGridView1.AllowUserToResizeColumns = True
        Else
            DataGridView1.AllowUserToResizeColumns = False
        End If

        If My.Settings.MyAllowUserToResizeRows = True Then
            DataGridView1.AllowUserToResizeRows = True
        Else
            DataGridView1.AllowUserToResizeRows = False
        End If

        If My.Settings.MyAutoSizeColumnsMode = 16 Then
            DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill
        Else
            DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None
        End If

Form 2 - save button

Private Sub btn_save_Click(sender As Object, e As EventArgs) Handles btn_save.Click

        If chk_AllowUserToResizeColumns.Checked = True Then
            Form1.DataGridView1.AllowUserToResizeColumns = True
            My.Settings.MyAllowUserToResizeColumns = True
        Else
            Form1.DataGridView1.AllowUserToResizeColumns = False
            My.Settings.MyAllowUserToResizeColumns = False
        End If

        If chk_AllowUserToResizeRows.Checked = True Then
            Form1.DataGridView1.AllowUserToResizeRows = True
            My.Settings.MyAllowUserToResizeRows = True
        Else
            Form1.DataGridView1.AllowUserToResizeRows = False
            My.Settings.MyAllowUserToResizeRows = False
        End If

        If chk_AutoSizeColumnsMode.Checked = True Then
            Form1.DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill
            My.Settings.MyAutoSizeColumnsMode = 16
        Else
            Form1.DataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.None
            My.Settings.MyAutoSizeColumnsMode = 1
        End If

        Try
            My.Settings.Save()
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

        Close()

End Sub

You can simplify this:

If My.Settings.MyAllowUserToResizeColumns = True Then
DataGridView1.AllowUserToResizeColumns = True
Else
DataGridView1.AllowUserToResizeColumns = False
End If

to this:

DataGridView1.AllowUserToResizeColumns = My.Settings.MyAllowUserToResizeColumns

My.Settings.MyAutoSizeColumnsMode = 16

It is better if you change the setting type to DataGridViewAutoSizeColumnsMode. In type selection click 'Browse...' and find it under System.Windows.Forms.

Thank you JohnH for your tips, very useful.
I would like to ask, how can I use this code or a part of it as a template for my next projects?

Create project templates with wizard or XML file - Visual Studio (Windows)

Create project templates in Visual Studio with the Export Template Wizard, or by grouping the project files and using a .vstemplate XML file.
