私はgridviewの編集に取り組んでいます。チェックボックスも追加しました。私はユーザーがチェックボタンをクリックするときにチェックする必要があります、それは真の価値を与える必要があります。偽でない場合。 私のグリッドビューです。追加情報：文字列が有効なブール値として認識されませんでした

ページの実行中にエラーが発生しました。エラーは文字列が有効なブール値として認識されないことです。
コード：
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int productId = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value);
TextBox productName = GridView1.Rows[e.RowIndex].FindControl("ProductTextBox") as TextBox;
TextBox description = GridView1.Rows[e.RowIndex].FindControl("DescriptionTextBox") as TextBox;
TextBox itemsInSet = GridView1.Rows[e.RowIndex].FindControl("ItemsTextBox") as TextBox;
TextBox unitPriceOwner = GridView1.Rows[e.RowIndex].FindControl("PriceOwnerTextBox") as TextBox;
TextBox unitPriceReseller = GridView1.Rows[e.RowIndex].FindControl("PriceResellerTextBox") as TextBox;
TextBox shippingCost = GridView1.Rows[e.RowIndex].FindControl("CostTextBox") as TextBox;
TextBox inOffer = GridView1.Rows[e.RowIndex].FindControl("InOfferTextBox") as TextBox;
CheckBox visible = GridView1.Rows[e.RowIndex].FindControl("VisibleCheckBox") as CheckBox;
Product product = new Product();
product.ProductID = productId;
product.ProductName = productName.Text;
product.Description = description.Text;
product.ItemsInSet = Convert.ToInt32(itemsInSet.Text);
product.UnitPriceOwner = Convert.ToInt32(unitPriceOwner.Text);
product.UnitPriceReseller = Convert.ToInt32(unitPriceReseller.Text);
product.ShippingCost = Convert.ToInt32(shippingCost.Text);
product.InOffer = Convert.ToBoolean(inOffer.Text);
product.Visible = Convert.ToBoolean((visible.Text).ToString());
ProductBL.UpdateProduct(product);
GridView1.EditIndex = -1;
GridView1.DataSource = ProductBL.GetProducts();
GridView1.DataBind();
}
