Filter int32 filed in RadGridView according to textbox

Question

I have a main form frmInnovation that contains a textbox txtInnovationID, and I have a Telerik RadGridView on the form TableSituations with a column InnovationNameID of type int32.
What I want to do is to filter the RadGridView on form load according to the txtInnovationID.

TableSituation.InnovationNameID = txtInnovationID

I use this code to filter strings, but how to modify to filter int32.

BindingSource bs = new BindingSource();
bs.DataSource = TableSituations.DataSource;
bs.Filter = TableSituations.Columns[2].HeaderText.ToString() + " LIKE '%" + txtInnovationID.Text + "%'";
TableSituations.DataSource = bs.DataSource;

 I need also to change the code from "LIKE" to "Equals".
