Hi,

I have a GridView on a form which is giving me this error:

Unable to cast object of type 'OakLeaf.MM.Main.Web.UI.WebControls.mmGridView' to type 'OakLeaf.MM.Main.Web.UI.ImmWebBindingSimple'.

When I do this:

            this.oPolicyRider.NewRow(dsPolicyRider, this.oPolicyRider.TableName);
            Guid newPK = (Guid)dsPolicyRider.Tables[0].Rows[dsPolicyRider.Tables[0].Rows.Count - 1]["PolicyRiderPK"];

            // Get the list of Riders & Waivers available for this plan
            this.dsRiders = this.oPlan.GetRidersAndWaiversByPlan(this.oPolicy.Entity.PlanFK);
            // default the Rider to the first item in the Riders data session
            dsPolicyRider.Tables[0].Rows[dsPolicyRider.Tables[0].Rows.Count - 1]["RiderFK"] = this.dsRiders.Tables[0].Rows[0]["PlanPK"];

            // default the CountryFK to the first item in the Country data session
            //dsAddress.Tables[0].Rows[dsAddress.Tables[0].Rows.Count - 1]["CountryFK"] = this.oCountry.DataSet.Tables[0].Rows[0]["CountryPK"];

            this.BindControl(this.grdRiders);

The error occurs on the BindControl line.

I've done many grids like this and not seen this error before, so I figure it's something simple but can't see what is wrong.

Any help appreciated.
