c# - MVCGrid.Net - 分页不限制结果或页码不显示

Question

我正在使用 MVCGrid.Net，我正在尝试向网格添加分页，这是我的代码：

GridDefinition<DepositLog> def = new GridDefinition<DepositLog>();

GridColumn<DepositLog> ID = new GridColumn<DepositLog>();
ID.ColumnName = "ID";
ID.HeaderText = "ID";
ID.HtmlEncode = false;
ID.ValueTemplate = "<input type='text' name='ID' value='{Value}' class='form-control' />";
ID.ValueExpression = (i, c) => i.id.ToString();
def.AddColumn(ID);

GridColumn<DepositLog> PayTo = new GridColumn<DepositLog>();
PayTo.ColumnName = "PayTo";
PayTo.HeaderText = "PayTo";
PayTo.HtmlEncode = false;
PayTo.ValueTemplate = "<input type='text' name='PayTo' value='{Value}' class='form-control' />";
PayTo.ValueExpression = (i, c) => i.PayTo.ToString();
def.AddColumn(PayTo);

GridColumn<DepositLog> Category = new GridColumn<DepositLog>();
Category.ColumnName = "Category";
Category.HeaderText = "Category";
Category.HtmlEncode = false;
Category.ValueTemplate = "<input type='text' name='Category' value='{Value}' class='form-control' />";
Category.ValueExpression = (i, c) => i.Category.ToString();
def.AddColumn(Category);

def.Paging = true;
def.ItemsPerPage = 10;

def.RetrieveData = (options) =>
{
    return new QueryResult<DepositLog>()
    {
        Items = _modelItems,
        TotalRecords = 0
    };
};

try
{
    MVCGridDefinitionTable.GetDefinition<DepositLog>("DepositLogGrid");
}
catch (Exception e)
{
    MVCGridDefinitionTable.Add("DepositLogGrid", def);
}

我在这里关注了这个演示：http: //mvcgrid.net/demo/paging

我的代码有点不同，因为我有多个控制器，每个控制器都有一个网格，所以我在控制器中定义了我的网格，但是是的……我的分页没有出现，所有的结果都出现了……我做错了什么?

解决了它：

def.Paging = true;
            def.ItemsPerPage = 25;
            def.MaxItemsPerPage = 25;

            def.RetrieveData = (context) =>
            {

                var options = context.QueryOptions;

                var result = new QueryResult<DepositLog>();

                var query = _modelItems.AsQueryable();

                result.TotalRecords = query.Count();

                if (options.GetLimitOffset().HasValue)
                {
                    query = query.Skip(options.GetLimitOffset().Value).Take(options.GetLimitRowcount().Value);
                }
                result.Items = query.ToList();

                return result;
            };
