#14809 |

Hello, ive got the next problem… i want to insert a coomboBiox in a Xceed Grid.
All works fine, but if the property SelectedItem doesnt work and i cant select one of the items in the grid when this grid its displayed for first time.

Where are us wrong?

Imports Xceed.Grid
Imports Xceed.Editors
Imports Xceed.Grid.Editors
Imports Xceed.Grid.Viewers

Public Class Form1

Private SuggestedWorker As Column

Private CoordinatorNameColumn As ColumnInfo
Private selc As ComboBoxEditor
Private sel As WinComboBox
Dim row As DataRow
Private item As ComboBoxItem
Private selectedItem As ComboBoxItem

Public Sub New()
Xceed.Editors.Licenser.LicenseKey = “EDN20-???……………”
Xceed.Grid.Licenser.LicenseKey = “GRD30-??……………..”
‘ This call is required by the Windows Form Designer.
InitializeComponent()
‘ Add any initialization after the InitializeComponent() call.
InitializeSelectionGridControl()

End Sub

Private Sub InitializeSelectionGridControl()
Dim coordinators As New List(Of String)()
SuggestedWorker = New Column(“Suggested Worker”, GetType(WinComboBox))
SuggestedWorker.Width = 100
Me.CoordinatorGridControl.Columns.Add(SuggestedWorker)

CoordinatorNameColumn = New ColumnInfo(“Name”, GetType(String))

coordinators.Add(“luis”)
coordinators.Add(“pedro”)
coordinators.Add(“pedro3”)
coordinators.Add(“pedro4”)

Me.sel = New WinComboBox()
Me.sel.Columns.Add(CoordinatorNameColumn)
Me.sel.MaxDropDownItems = 5
Me.sel.IntegralHeight = True

For Each coor As String In coordinators
item = New ComboBoxItem({coor})
Me.sel.Items.Add(item)
Next
Me.sel.SelectedItem = Me.sel.Items(0)

Dim a As New ComboBoxViewer(sel)

row = Me.CoordinatorGridControl.DataRows.AddNew()
Me.selc = New ComboBoxEditor(sel)
row.Cells(“Suggested Worker”).CellEditorManager = Me.selc
row.Cells(“Suggested Worker”).CellEditorDisplayConditions = CellEditorDisplayConditions.Always
row.EndEdit()
End Sub
End Class

This will work only on the specific editor, not on the template. When you set the CellEditorManager, this is only a template that is used to create each cells of the column. So to get the ComboBox to display a specific item, you need to get to the specific editor in that cell, which is available only once it is create, that is, when the grid is fill with data.

To get to the specific editor of a cell, you need to first activate the editor in the cell.

e.g. :

gridControl1.DataRows[ 0 ].Cells[ 0 ].EnterEdit();

Then you can use the SelectedItem property to display the item you want.

e.g. :

( ( WinComboBox )gridControl1.DataRows[ 0 ].Cells[ 0 ].CellEditorControl).SelectedItem = ( ( WinComboBox )gridControl1.DataRows[ 0 ].Cells[ 0 ].CellEditorControl).Items[ 2 ];

Note that doing this may put much overhead to the loading of the grid, depending on how many rows there is in the grid.
