hello,
I'm currently working with a xamdatagrid, this grid is bound to a dataset as
its source, and what im trying to do is, based on the column name(or the
field name as the xamdatagrid calls it i think) i want to make that field
invisible but every time ive tried it says object not referenced to an
instance of an object. heres the code im working with, i figure if i can
figure it out here i can use it in another program
Imports System.Data
Imports Infragistics.Wi ndows.DataPrese nter
Class Window1
Sub Samp_Loaded(ByV al o As Object, ByVal e As RoutedEventArgs )
'create data using GenerateData Method
Dim ds As DataSet = generatedata()
'create an instance of xamdatagrid
Dim MyxamDataGrid As New XamDataGrid
'give name
MyxamDataGrid.N ame = "XamDataGri d1"
'set its datasource property to the default view of
'the dataset created earlier
MyxamDataGrid.D ataSource = ds.Tables(0).De faultView
' MyxamDataGrid.D efaultFieldLayo ut.Visibility =
Windows.Visibil ity.Hidden
'add the newly created xamdatagrid to the grid panel's
'children collection
'If MyxamDataGrid.R ecordManager.Fi eld.Name = "Title" Then
MyxamDataGrid.R ecordManager.Fi eld.Visibility =
Windows.Visibil ity.Hidden
' End If
MyGrid.Children .Add(MyxamDataG rid)
'find way to make certain column invisible
' ds.Tables("dt") .Columns("Title ").DefaultV alue =
Windows.Visibil ity.Visible = False
'ds.Container.C omponents.Item( Title).Equals(V isibility = False)
End Sub
Function generatedata() As DataSet
Dim ds As New DataSet
Dim dt As DataTable = ds.Tables.Add(" TopMovies")
dt.Columns.Add( "Title", GetType([String]))
dt.Columns.Add( "Running Time", GetType(String) )
dt.Columns.Add( "MPAA Rating", GetType(String) )
dt.Columns.Add( "Critics Rating", GetType(String) )
dt.Rows.Add(New Object() {"Open Season", "1 hr. 40 min.", "PG",
"C"})
dt.Rows.Add(New Object() {"Gridiron Gang", "120 min.", "PG-13",
"C+"})
dt.Rows.Add(New Object() {"The Illusionist", "1 hr. 49 min.", _
"PG-13", "B"})
dt.Rows.Add(New Object() _
{"Talladega Nights: The Ballad of Ricky Bobby", "1 hr. 50 min.", _
"PG-13", "B"})
dt.Rows.Add(New Object() _
{"Pirates of the Caribbean: Dead Man's Chest", "145 min.", _
"PG-13", "B-"})
Return ds
End Function
End Class
thank you in advance
