编辑数据gridview

Question

我有 gridview 从数据库中检索数据。我在数据 ingridview 中做了更新语句我做了我的代码但是当我在 gridview 中选择编辑选项时出现此错误 （过程或函数“Update_IntoModel”需要参数“@Id”，但未提供） .

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        int RowAffected = 0;
        GridView1.EditIndex = e.NewEditIndex;
        using (SqlConnection con = Connection.GetConnection())
        {
            SqlCommand Com = new SqlCommand();
            Com = new SqlCommand("Update_IntoModel", con);
            Com.CommandType = CommandType.StoredProcedure;
            Com.Parameters.Add(Parameter.NewInt("@Id", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Model_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Model_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Url", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Resolution_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Resolution_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Warranty_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Warranty_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Dimensions_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Dimensions_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@ContrastRatio_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@ContrastRatio_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Brightness_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@Brightness_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@PanelResposeSpeed_EN", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewNVarChar("@PanelResposeSpeed_AR", GridView1.SelectedValue));
            Com.Parameters.Add(Parameter.NewBit("@Active", GridView1.SelectedValue));
            RowAffected = Com.ExecuteNonQuery();
            if (RowAffected > 0)
            {
                LblResult.Visible = true;
                LblResult.Text = "Successfully Proccess";
                Update.Visible = false;

            }

        }

检查可能导致错误的参数@Id的名称。

还要检查您传递的参数数量和过程中的参数数量。
