Dataset, XML and datagrids

P: n/a
I would not have thought that getting a DataGrid connected to a DataSet
(read in from an XML file) would be this complicated. I cannot get this to
work. I have read everything I could find and modeled all the examples
given but this grid just refuses to behave nicely.

The code is listed below as well as the XML schema and XML data.

The connection between the data set and grid seems to work just fine. What
won't work is the display of the data. No matter what I do, the grid is
always displayed collapsed. I also do not want to display the "Mappings:"
caption that appears above the column headers. The column headers do not
seem to respond to the .width command.

I also read something about a SetDataBindings command that I do not know if
I need or not. Some code has it, some doesn't.

Any help would be, well, helpful.

Thanks.

Steve

Hi Steve,

Some observations and suggestions:

1. All the table style / column style setup stuff should go BEFORE the data
binding occurs. This seems to be not the case in your code and this is the
most likely reason of the problem.

2. It is strongly recommended to use SetDataBinding method instead of
setting the DataSource and DataMember properties directly. The reason seems
to be that this method does some additional but necessary work behind the
scenes which is not done when raw properties are being set.

Hope this helps.

P: n/a
Thanks for the help.

I moved the binding statement as such.

Private Sub BindXMLtoGrid()

Dim ts As DataGridTableStyle

Dim cs As DataGridTextBoxColumn

'create a custom tablestyle and add three columnstyles

ts = New DataGridTableStyle()

ts.MappingName = "tsSymbolMapping"

' create a column for TC2000

cs = New DataGridTextBoxColumn()

cs.MappingName = "TC2000"

cs.HeaderText = "TC2000 Symbol"

cs.Width = 40

cs.NullText = ""

ts.GridColumnStyles.Add(cs)

:

:

dgTest.TableStyles.Clear()

dgTest.TableStyles.Add(ts)

dgTest.CaptionVisible = False

dgTest.SetDataBinding(dsTM, "tsSymbolMapping")

ts = Nothing

cs = Nothing

End Sub

The statement

dgTest.SetDataBinding(dsTM, "tsSymbolMapping")

is giving me errors now. It says "Can't create a child list for field
tsSymbolMapping. This was giving me fits earlier. What is the datamember
that is supposed to go here?

Thanks again.

Steve
