Question

我正在关注使用needdatasource（click here to view telerik demo）将数据绑定到radgrid的示例。

这是我的HTML代码，

<telerik:RadGridID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" AllowSorting="True" AllowPaging="True" ShowGroupPanel="True" GroupingSettings-CaseSensitive="false" AllowFilteringByColumn="True" CellSpacing="-1" GridLines="Both"
Skin="Metro" CssClass="rad_header_style" Width="100%">
  </telerik:RadGrid>

以下是我如何从代码中绑定数据

using System;
using System.Data;
using System.Linq;
using Telerik.Web.UI;

publicpartialclasstime_and_action_ganttchart_details : System.Web.UI.Page
{
    protectedvoidPage_Load(objectsender, EventArgs e)
    {

    }

    protectedvoidRadGrid1_NeedDataSource(objectsender, GridNeedDataSourceEventArgs e)
    {
        shorttechpackID = 93; // short.Parse(Request.QueryString[0]);

        DataTable dt = newDataTable();

        dt.Columns.Add("Customer", typeof(string));
        dt.Columns.Add("Account", typeof(string));
        dt.Columns.Add("Season", typeof(string));
        dt.Columns.Add("Program", typeof(string));
        dt.Columns.Add("Tech Pack Name", typeof(string));
        dt.Columns.Add("Design Ref", typeof(string));
        dt.Columns.Add("Stroke", typeof(string));
        dt.Columns.Add("Type", typeof(string));
        dt.Columns.Add("Assortment Name", typeof(string));
        dt.Columns.Add("Component", typeof(string));
        dt.Columns.Add("RM Description", typeof(string));
        dt.Columns.Add("Supplier", typeof(string));
        dt.Columns.Add("CSP", typeof(string));
        dt.Columns.Add("Mode", typeof(string));
        dt.Columns.Add("RM Color Code", typeof(string));
        dt.Columns.Add("RM Color Name", typeof(string));
        dt.Columns.Add("Silhoutte", typeof(string));
        dt.Columns.Add("Garment Number", typeof(string));

        using(PDLC.Data.PDLCEntities context = newPDLC.Data.PDLCEntities())
        {
            var version = context.V_TimeAndAction_TechPackLeadTime.Where(x => x.TP_ID == techpackID).Select(s => new{ s.VersionID }).Max(p => p.VersionID);

                dt.Columns.Add("Actual "+ eventname.EventText, typeof(string));
                dt.Columns.Add("Committed "+ eventname.EventText, typeof(string));
            }

                    var eventIdList = context.V_TimeAndAction_TechPackLeadTime.Where(x => x.TP_ID == techpackID && x.VersionID == version && x.AS_ID == assortmentId.AS_ID && x.RawMaterialID == rawmaterial.RawMaterialID).Select(s => new{ s.EventID, s.EventOrder, s.EventText }).Distinct().OrderBy(o => o.EventOrder);

                    foreach(var eventId ineventIdList)

                            dr["Actual "+ eventId.EventText] = timeandactionactual.ToShortDateString();

                        if(timeandactiondates.CommittedDate != null)
                        {

                        }
                        else
                        {
                            dr["Committed "+ eventId.EventText] = timeandactiondates.CommittedDate;
                        }
                    }
                    dt.Rows.Add(dr);                   
                }
            }
        }
        RadGrid1.DataSource = dt;       
    }
}

现在我想要隐藏过滤器图标并将列搜索过滤条件设置为包含（CurrentFilterFunction =＆＃34;包含＆＃34; ShowFilterIcon =＆＃34; false＆＃34;）。

希望尽快收到你的回复。谢谢。

你有三个选择

使用OnColumnCreated事件，event arguments为您提供列
或者，使用Page_PreRender事件并循环遍历RadGrid1.Columns集合。如果您知道所有字段名称，也可以使用RadGrid1.MasterTableView.GetColumnSafe（＆＃34; DataSourceFieldName＆＃34;）来获取列。
或者，使用所需的设置在标记中声明您的列

如何设置CurrentFilterFunction =＆＃34;包含＆＃34; ShowFilterIcon =＆＃34;假＆＃34;在TELERIK RadGrid中与NeedDataSource进行数据绑定时的列中
