Value memberWe can find an item using ValueMember property, by deriving ComboBoxAdv and using reflection, ComboBoxAdv item can be retrived using ValueMember property. C# public int FindTextByValue(object Value) { int i = -1; if (this.DataSource != null) { string val = Value.ToString(); IList collection = (IList)this.DataSource; foreach (object o in collection) { Type t = o.GetType(); if (t != null) { PropertyInfo propertyInfo = t.GetProperty(this.ValueMember); i++; if (propertyInfo.GetValue(o, null).ToString() == val) { break; } } } } return i; }
VB Public Function FindTextByValue(ByVal Value As Object) As Integer Dim i As Integer = -1 If Me.DataSource IsNot Nothing Then Dim val As String = Value.ToString() Dim collection As IList = CType(Me.DataSource, IList) For Each o As Object In collection Dim t As Type = o.GetType() If t IsNot Nothing Then Dim propertyInfo As PropertyInfo = t.GetProperty(Me.ValueMember) i += 1 If propertyInfo.GetValue(o, Nothing).ToString() = val Then Exit For End If End If Next o End If Return i End Function Sample: |
