Datagrid column width won't change

[Ben]

Could someone please tell me why couldn't I adjust my column/row properties
of my dataGrid? I binded my table, created a new DataGridTableSt yle and
mapped it to my datagrid. However, my columns width wouldn't changed at all.
I am sure this is very easy thing to figure out but I just couldn't see it.
Could you please take a look at my codes. What I am missing? Btw, I got
these codes from MSDN website:

thanks.

.....
Private myDataGrid As DataGrid
Private myDataSet As DataSet
Private TablesAlreadyAd ded As Boolean
Private ts1 As New DataGridTableSt yle
....

from my default constructor, I rand SetUp()
......
Private Sub SetUp()
'create a dataset with two tables and one relation.
MakeDataSet()
'bind the datagrid to the dataset. the datamember
'specifies that the customers table should be displayed.
myDataGrid.SetD ataBinding(myDa taSet, "customers" )

Dim ts1 As New DataGridTableSt yle
ts1.MappingName = "customers"
Dim myDataCol As New DataGridBoolCol umn
myDataCol.Heade rText = "My New Column"
myDataCol.Mappi ngName = "current"
myDataCol.Width = 4000000
ts1.GridColumnS tyles.Add(myDat aCol)
myDataGrid.Tabl eStyles.Add(ts1 )

End Sub
............... ......along that path, it should execute this dataset then
bind to myDataGrid
Private Sub MakeDataSet()
myDataSet = New DataSet("myData Set")

Dim tCust As New DataTable("Cust omers")
Dim cRecordName As New DataColumn("Rec ord Name", GetType(Integer ))
Dim cUnitOfMeasurem ent As New DataColumn("Uni t Of Measurement")
Dim cSimulationCase No As New DataColumn("Sim ulation Case Number")
tCust.Columns.A dd(cRecordName)
tCust.Columns.A dd(cUnitOfMeasu rement)
tCust.Columns.A dd(cSimulationC aseNo)

myDataSet .Tables.Add(tCu st)

Dim newRow1 As DataRow

Dim i As Integer
For i = 1 To 3
newRow1 = tCust.NewRow()
newRow1("Record Name") = i
tCust.Rows.Add( newRow1)
Next i
tCust.Rows(0)(" Unit Of Measurement") = "Customer1"
tCust.Rows(1)(" Unit Of Measurement") = "Customer2"
tCust.Rows(2)(" Unit Of Measurement") = "Customer3"

tCust.Rows(0)(" Simulation Case Number") = "asdf"
tCust.Rows(1)(" Simulation Case Number") = "asdf"
tCust.Rows(2)(" Simulation Case Number") = "asdfdas"
End Sub

Hi,

The mappingname for the tablestyle is case sensitive. Try
using Customers instead of customers. Not sure if the datagrid supports
column widths of 4000000

Ben,

Mostly these errors come if you don't use the same cases as you do in your
code
This part is with windowsforms programming case sensitive (rarely it is not
with a webform datagrid).

I hope this helps,
