Filtering results from textbox to DataGridView

I want to filter/search some results from my existing DataGridView Table. I have done most of them except one field. That's the first field of my DataGridView Table "Product ID" it's an Int data type field. So I think it needs a bit conversion on the Int Value to System.String.. but I'm not getting how to fix that.. Can any one please help me..

C#

private void txtSearch_TextChanged(object sender, EventArgs e)
{
    try 
    {
        DataView DV = new DataView(dbdataset);
        DV.RowFilter = string.Format("Convert[Product ID, System.String] LIKE '%{0}%' OR [Product Name] LIKE '%{0}%' OR [Brand Name] LIKE '%{0}%' OR [Pro. Size ID] LIKE '%{0}%'", txtSearch.Text);
        dgView.DataSource = DV;
    }
     catch (Exception ex)
    {
        Error_txt.Text = ex.Message;
    }

}

It gives an error

Syntax error: Missing operand after '[Product ID, System.String]' operator.

If I recall a RowFilter is the same syntax as SQL. So, to convert, you do

CONVERT(NVARCHAR(50), [Product ID]) LIKE ...

Or, you may not have to convert at all. Sql will do some implicit conversions for you.

[Product ID] LIKE %{0}%

You can put row filter on this way

DV.RowFilter = string.Format("[Product ID]'{0}' OR [Product Name]='{0}' OR [Brand Name]='{0}' OR [Pro. Size ID]='{0}'", txtSearch.Text);
