Hi,
I grab this example file from a previous post, «Demo-DGVDataTable.psf» and I would like to know how can I add ComboBoxColum for the column «Age» for example or add a new column?

Thanks for your help.

A big Newbie




Demo-DGVDataTable.psf
$FormEvent_Load={
$dt = New-Object System.Data.DataTable
$dt.Columns.Add('FirstName', [string])
$dt.Columns.Add('LastName', [string])
$dt.Columns.Add('Age', [int])

$r = $dt.NewRow()
$r['firstname'] = 'Joe'
$r['lastname'] = 'smith'
$r['age'] = 45

$dt.Rows.Add($r)
$datagridview1.DataSource=$dt
}

$buttonExport_Click = {
$savefiledialog1.AddExtension='xml'
if ('Ok' -eq $savefiledialog1.ShowDialog()) {
$savexml = $savefiledialog1.FileName
$datagridview1.Rows | select -expand DataBoundItem | Export-Clixml -Path $savexml
}
}

$buttonNewPerson_Click={
$dr = $datagridview1.DataSource.NewRow()
if(.\New-PersonForm.ps1 $dr -eq 'Ok'){
$datagridview1.DataSource.Rows.Add($dr)
}
}

Hi. Thanks for moving the post.

The code you posted is part of a PSF PowerShell Studio project. You can use the designer to add columns and bind them to data by name.

What you have posted is just the added code from the script editor. Look at the blog posts showing how to manage the grid control. They are a good place to start learning how to use forms.

Hi,
I have add a ComboBoxColumn but when I click export the ComboBox value does not appear in the xml file. Also how can I put this column the last one.

Do you think you could modify the example file to show me how can I do that?

Thanks again.

If you use a combo box that is for a field you must bind the data name to the field name then it will connect.

I'm still searching

I have this error ""System.ArgumentException: DataGridViewComboBoxCell value is not valid."
when I run this command "$dataGridView1.Rows.Add($row.name, $row.fullname, $row.extension)"

How can I load data to DataGridViewComboBoxCell?

Thanks



Here is my sample code:

It's better to upload the psf file instead of posting it inline without Code Tags.

You can add items to the combobox in many ways. Here I sone:

$datagridview1.Columns['age'].Items.AddRange(@([int]45,[int]46,[int]47,[int]48))

Thanks for your help!
