Is There A Size Limit To This Cause Im Getting An Error That I Cant Figure Out

I create an sql string as so, add parameters to it and execute it:

string cmdstr = "INSERT INTO locations(id1, id2, companyname, address, city, province, postalcode, phonenumber, faxnumber, contact, contactemail) VALUES (@id1,@id2,@companyname,@address,@city,@province,@postalcode,@phonenumber,@faxnumber,@contact,@contactemail)";

SqlCommand sqlCmd = GetCommandSQL(cmdstr);

sqlCmd.CommandTimeout = TimeOut;

sqlCmd.Parameters.Add("@id1", SqlDbType.Int).Value = itID;

sqlCmd.Parameters.Add("@id2", SqlDbType.Int).Value = Convert.ToInt32(ddlDPCLocation.SelectedValue);

sqlCmd.Parameters.Add("@companyname", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbCompanyName")).Text;

sqlCmd.Parameters.Add("@address", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbAddress")).Text;

sqlCmd.Parameters.Add("@city", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbCity")).Text;

sqlCmd.Parameters.Add("@province", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbProvince")).Text;

sqlCmd.Parameters.Add("@postalcode", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbPostalCode")).Text;

sqlCmd.Parameters.Add("@phonenumber", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbPhoneNumber")).Text;

sqlCmd.Parameters.Add("@faxnumber", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbFaxNumber")).Text;

sqlCmd.Parameters.Add("@contact", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbContact")).Text;

sqlCmd.Parameters.Add("@contactemail", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbContactEmail")).Text;

sqlCmd.ExecuteNonQuery();

for testing purposes ive added the max text in each textbox area, so each textbox has 50 characters or so

and i get an error message as follows, when executing the query:

"System.Data.SqlClient.SqlException: String or binary data would be truncated.

Anybody have any ideas why this is happening
