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);


if (propertyInfo.GetValue(o, null).ToString() == val)







return i;



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
