I was able to control the columns being displayed. I had a create a columnset, populate that columnset with the properties of business objects (since columns are treated as properties) and then decide which columns to display and hide. Not an easy task however.

Creating a ColumnSet yourself from scratch is more complicated than simply handling the ColumnSetGenerated event. It's slightly more efficient, though, since you don't end up creating and then removing unneccessary columns. 

Now you tell me, j/k. I checked out the ColumnSetGeneratedEvent, I guess it does the same thing few less lines of Code. But the way I did it was little bit more complicated. Here's some code if anyone is interested in future

rootColumnSet.Key = "Display";

PropertyInfo[ properties = type.GetProperties(); //all the properties in the type

//DataTable

rootColumnSet.Columns.Add(p.Name); //add all columns according to the property Name in the Type T

this.GroupTree.Nodes.Override.ColumnSet = this.GroupTree.ColumnSettings.ColumnSets["Display"];

rootColumnSet.ColumnSettings.CellAppearance.BackColor = Color.Transparent;

rootColumnSet.Columns["Id"].Visible = false;

rootColumnSet.Columns["Type"].Visible = false;

Hi

Thanks for the help, i got the same prolem but mine is slightly different, as i have 3 tables in dataset which has to display as child nodes for each table

i got the results but am unable to hide columns in child records

please see the code below

mDSDocumentation =

Nothing

mProAdminDoc =

CType(Session.CreateProvider(AdminProviderTypes.Documentation), EDProAdminDocumentation)

mDSDocumentation = mProAdminDoc.GetAdminDocCategoryTabs(strCategory)

utAvailableListTree.ViewStyle = Infragistics.Win.UltraWinTree.ViewStyle.Standard

utAvailableListTree.DisplayStyle = Infragistics.Win.UltraWinTree.UltraTreeDisplayStyle.Standard

True

' Get the DataColumn objects from Three DataTable objects in a DataSet.

Dim parentColumn As DataColumn = mDSDocumentation.Tables(0).Columns("tab_id")

Dim childColumn As DataColumn = mDSDocumentation.Tables(1).Columns("parent_tab_id")

Dim childColumn1 As DataColumn = mDSDocumentation.Tables(1).Columns("tab_id")

Dim grandchildColumn As DataColumn = mDSDocumentation.Tables(2).Columns("parent_tab_id")

'Create DataRelation.

Dim relFirstLevel AsDataRelation

Dim relSecondLevel AsDataRelation

relFirstLevel =

New DataRelation("FirstRelation", parentColumn, childColumn)

relSecondLevel =

New DataRelation("SecondRelation", childColumn1, grandchildColumn)

' Add the relation to the DataSet.

mDSDocumentation.Relations.Add(relFirstLevel)

mDSDocumentation.Relations.Add(relSecondLevel)

'Binding the Datasource with Tree Control

utAvailableListTree.DisplayStyle = Infragistics.Win.UltraWinTree.UltraTreeDisplayStyle.Standard

utAvailableListTree.ViewStyle = Infragistics.Win.UltraWinTree.ViewStyle.Grid

utAvailableListTree.DataSource = mDSDocumentation.Tables(0)

"")

'To Make the Header False in the tree view

utAvailableListTree.ColumnSettings.LabelPosition = Infragistics.Win.UltraWinTree.NodeLayoutLabelPosition.None

utAvailableListTree.ColumnSettings.CellAppearance.BackColor = Color.Transparent

utAvailableListTree.ColumnSettings.CellAppearance.BorderColor = Color.Transparent

'To Make the unwanted column to be invisible in tree view

utAvailableListTree.ColumnSettings.ColumnSets(0).Columns(

"tab_id").Visible = False

utAvailableListTree.ColumnSettings.ColumnSets(0).Columns(

"tab_name").Visible = True

"discription").Visible = False

"parent_tab_id").Visible = False

"display_order").Visible = False

 and the result coming as below

+ Triage

                 + 123   Test Testing 12 9

i wish to hide the other columns in child also, any help in this will be most appriciated
