I have a CheckedListBox with 3 columns.
But, I can't figure out how to set the width of each column even though I have used the code shown below;
Private Sub BuildListBoxColumns()
Dim nameColumn As New ListViewDetailColumn("Line Item Description")
nameColumn.HeaderText = "Line Item Description"
nameColumn.MinWidth = 800
nameColumn.Width = 800
Me.lbInvoiceItems.Columns.Add(nameColumn)
Dim SKUColumn As New ListViewDetailColumn("SKU")
SKUColumn.HeaderText = "SKU"
SKUColumn.MinWidth = 120
SKUColumn.Width = 120
Me.lbInvoiceItems.Columns.Add(SKUColumn)
Dim QtyColumn As New ListViewDetailColumn("Qty")
QtyColumn.HeaderText = "Qty"
QtyColumn.MinWidth = 80
QtyColumn.Width = 100
Me.lbInvoiceItems.Columns.Add(QtyColumn)
End Sub
The MinWidth on each columns simply doesn't work.
How do I properly set the minwidth for each column?
it's probably something simple, but I cannot see why this isn't working

Hello, Martin,
The MinWidth property specifies the minimum width that the column can be resized to. I tested this property locally and it is working fine. In your code snippet, you have 'Line Item Description' which has MinWidth=800. This means that you can resize this column more than 800px but you can not make it smaller than 800px. Please refer to the provided gif file that demonstrates this. The same behavior is observed with the other two columns from your setup. I am providing my test project for your reference.
As to the other question, if you need to format cells in DetailsView you should handle the CellFormatting event and set the TextAlignment property for the cells.
I hope this information helps. Let me know if you have further questions.

I guess the issue I'm seeing must be due to the CheckListBox being databound.
As you'll see in the images below - I cannot achieve the desired width.
is there a way that I can add a (AddRange) progrmatically to populate the rows/columns - it'll probably work if it's not databound?
Something along the lines of this? This however doesn't work for me.
'For Each myrow As DataRow In dtData.Rows
' lbInvoiceItems.Columns.AddRange(myrow("LineItemDesc"), myrow("SKU"), myrow("LineItemQty"))
'Next
Hello, Martin,
With data-bound RadCheckedListBox, you can specify the MinWidth of the columns as well. After setting the data source via the DataSource property you can access the desired columns either by index or name and set the MinWidth:
Public Sub New()
InitializeComponent()
Me.RadCheckedListBox1.DataSource = Me.CreateSimpleObjects()
Me.RadCheckedListBox1.DisplayMember = "Name"
Me.RadCheckedListBox1.ValueMember = "Id"
Me.RadCheckedListBox1.CheckedMember = "CheckState"
Me.RadCheckedListBox1.Columns(0).MinWidth = 300
Me.RadCheckedListBox1.Columns(1).MinWidth = 300
Me.RadCheckedListBox1.Columns(2).MinWidth = 300
End Sub
In case you have further difficulties, it would be greatly appreciated if you can provide more information about what is the exact goal that you are trying to achieve.
I hope this helps. Let me know if I can assist you further.
