ASPxGridListEditor: ToolTip in Data

Hi Ricardo,
The View.CurrentObject is usually Null in a web list view. Please use the ASPxGridView.GetRowValues method to access other column values, and pass the current row visible index to it. This method retrieves values directly from the data object even if there's no column for that field. Please try the following code (in MainDemo):

Visual Basic
Public Class MyController  
    Inherits ViewController  
    Public Sub New()  
        TargetObjectType = GetType(Contact)  
        TargetViewType = ViewType.ListView  
    End Sub  
    Protected Overrides Sub OnViewControlsCreated()  
        MyBase.OnViewControlsCreated()  
        Dim editor As ASPxGridListEditor = TryCast((CType(View, ListView)).Editor, ASPxGridListEditor)  
        If editor Is Nothing Then  
            Return  
        End If  
        AddHandler editor.Grid.HtmlDataCellPrepared, AddressOf Grid_HtmlDataCellPrepared  
    End Sub  
    Private Sub Grid_HtmlDataCellPrepared(ByVal sender As Object, ByVal e As DevExpress.Web.ASPxGridView.ASPxGridViewTableDataCellEventArgs)  
        Dim grid As ASPxGridView = CType(sender, ASPxGridView)  
        If e.DataColumn.FieldName = "Email" Then  
            e.Cell.Attributes.Add("title", Convert.ToString(grid.GetRowValues(e.VisibleIndex, new string[] { "TitleOfCourtesy" })));  
        End If  
    End Sub  
End Class
