Setting the length of datagrid columns

[bob]

I am binding a datatable to a datagrid in VB.NET I then want to change
the width of the first column. I am unable to get the right syntax.

Here is the code I tried
Dim mydataset As DataSet

gclodatabase.Ge tDataSetJobs("S elect * from qryJobs",
mydataset)
Dim Mydatatable As DataTable = mydataset.Table s(0)
dtgSelect.DataS ource = mydataset.Table s(0)

dtgSelect.Table Styles(0).GridC olumnStyles("Jo bId").Width = 10

‘ this fails with an error An unhandled exception of type
'System.NullRef erenceException ' occurred in Proposals.exe

‘Additional information: Object reference not set to an instance of an
‘object.
dtgSelect.Table Styles(0).GridC olumnStyles(1). Width = 10

‘ this fails with error

‘An unhandled exception of type 'System.Argumen tOutOfRangeExce ption'
‘occurred in mscorlib.dll

‘Additional information: Index was out of range. Must be non-negative
‘and less than the size of the collection.
dtgSelect.Refre sh()

Hi
You need to add the TableStyle "JobID" to the datagrid
before you can use it.
Kind Regards

Can you show me what the line of code is to do that?
