PowerShell Windows Forms DatagridView blank

Hi Experts

Am having a small issue with PowerShell when using a DatagridView in Windows Forms.

The DatagridView is being added to the form, but when the form is shown for the first time, it is "blank".  Or better said, the DatagridView is a White box.

Here is the code I use:

Add-Type -AssemblyName System.Windows.Forms

$objFrm = New-Object System.Windows.Forms.Form
$dgv_Info = New-Object System.Windows.Forms.DataGridView

$objFrm.Size = New-Object System.Drawing.Size(722, 563)
$objFrm.MinimumSize = New-Object System.Drawing.Size(722, 563)

$dgv_Info.Location = New-Object System.Drawing.Point(13, 342)
$dgv_Info.Size = New-Object System.Drawing.Point(681, 145)
$dgv_Info.Anchor = $AnchorStyle_BottomLeftRight
$dgv_Info.ColumnHeadersVisible = $true
$dgv_Info.RowHeadersVisible = $true
$dgv_cbCellSQLInst = New-Object System.Windows.Forms.DataGridViewComboBoxCell
$dgv_cbCellSQLInst.DataSource = $SQLInstanceNumbers
$outvar = $dgv_Info.Columns.Add($dgv_cbCellSQLInst)
$dgv_Info.Columns[0].Name = "Header 1"
$dgv_Info.Columns[0].AutoSizeMode = 'Fill'
$dgv_Info.Sort($dgv_Info.Columns[0], [System.ComponentModel.ListSortDirection]::Ascending)
$dgv_cbCellDrv = New-Object System.Windows.Forms.DataGridViewComboBoxCell
$dgv_cbCellDrv.DataSource = $DrvLetters
$outvar = $dgv_Info.Columns.Add($dgv_cbCellDrv)
$dgv_Info.Columns[1].Name = "Header 2"
$dgv_Info.Columns[1].AutoSizeMode = 'Fill'
$dgv_DBDisk = New-Object System.Windows.Forms.DataGridViewTextBoxCell
$outvar = $dgv_Info.Columns.Add($dgv_DBDisk)
$dgv_Info.Columns[2].Name = "Header 3"
$dgv_Info.Columns[2].AutoSizeMode = 'Fill'
$dgv_LogDisk = New-Object System.Windows.Forms.DataGridViewTextBoxCell
$outvar = $dgv_Info.Columns.Add($dgv_LogDisk)
$dgv_Info.Columns[3].Name = "Header 4"
$dgv_Info.Columns[3].AutoSizeMode = 'Fill'
$dgv_TempDisk = New-Object System.Windows.Forms.DataGridViewTextBoxCell
$outvar = $dgv_Info.Columns.Add($dgv_TempDisk)
$dgv_Info.Columns[4].Name = "Header 5"
$dgv_Info.Columns[4].AutoSizeMode = 'Fill'
$dgv_BckpDisk = New-Object System.Windows.Forms.DataGridViewTextBoxCell
$outvar = $dgv_Info.Columns.Add($dgv_BckpDisk)
$dgv_Info.Columns[5].Name = "Header 6"
$dgv_Info.Columns[5].AutoSizeMode = 'Fill'
$dgv_Info.add_CellValueChanged($dgv_Info_CellValuechanged)
$dgv_Info.add_UserDeletedRow($dgv_Info_UserDeletedRow)

$objFrm.Controls.Add($dgv_Info)

$objFrm.ShowDialog()

Select allOpen in new window

The form loads as this:


The DatagridView is shown properly when I either click into a field of the DatagridView or when I press Tab.  Once I have done this, the Datagrid is displayed correctly:


Can anyone help me Display the DataGridView correctly when it loads for the first time?
