ASPxGridView - Change default value of Filter Row condition

Hello Scott,
Thank you for your reply.
Usually it is known what type column data items have. You can check the column's FieldName property and initialize the AutoFilterCondition setting only for necessary columns.
If you need to check a data item's type at runtime, you need to use the ASPxClientGridView.GetRowValues method:

C#
protected void Page_Load(object sender, EventArgs e) {  
    if (!IsPostBack)  
        foreach (GridViewColumn col in grid.Columns) {  
            GridViewDataColumn c = col as GridViewDataColumn;  
            if ((c != null)  
                && !(c.Grid.GetRowValues(0, c.FieldName) is int)) {  
                c.Settings.AutoFilterCondition = AutoFilterCondition.Contains;  
            }  
        }  
}  

If you have any other questions, please contact us at any time.
Updated, Owner's solution:
Here is a VB version in case anyone needs.
This sub is ran on initial Page_Load event.
Public Sub SetGridViewFilterModeToContains(ByVal gv As ASPxGridView)
            For Each col As GridViewColumn In gv.Columns
                Dim c As GridViewDataColumn = TryCast(col, GridViewDataColumn)
                If (c IsNot Nothing) AndAlso Not (TypeOf c.Grid.GetRowValues(0, c.FieldName) Is Integer) Then
                    c.Settings.AutoFilterCondition = AutoFilterCondition.Contains
                End If
            Next
End Sub
