계절에 맞춰 인사드립니다. 이것이 나를 미치게 만드는 데 도움이 필요합니다.Gridview 분류, 업데이트 및 편집
목표입니다. 나는 클라이언트가 숫자를 입력하는 텍스트 박스를 가지고 있으며, 라디오 버튼 목록을 클릭하여 머티리얼을 선택하고 버튼을 눌러 그리드 뷰를 채 웁니다.
이 프런트 엔드 코드 :

Text="Display TOP Report" onclick="btnDisplayTopReport_Click" />
<asp:RadioButtonList ID="radTOP" runat="server"
style="z-index: 1; left: 575px; top: 180px; position: absolute; height: 177px; width: 86px">

그리고 이것은 뒤에 코드 :
public partial class TOP : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Session["MemberKey"] = "FM00012";
GridView1.DataSourceID = null;
GridView1.DataBind();
}
}
private object GetMaterialData(string MemberKey, string MaterialType, string MaterialLevel, int Count)
{
CompleteWeightsDataContext db = new CompleteWeightsDataContext();
var query = db.tblOnlineReportingCOMPLETEWeights
.Where(x => x.MemberId == MemberKey && x.MaterialText == MaterialType && x.MaterialLevel == MaterialLevel)
.OrderByDescending(x => x.ProductPercentage)
.Take(Count);
return query;
}
protected void btnDisplayTopReport_Click(object sender, EventArgs e)
{
GridView1.DataSourceID = null;
GridView1.DataBind();
if (radTOP.SelectedValue == "" || tbxHowMany.Text == "")
{
MessageBox.Show("Please Ensure that BOTH 'The Number of Products' and Appropriate material Is selected Before You Attempt To Run a TOP X Report", "Top X Error!!!",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
GridView1.DataSourceID = null;
GridView1.DataBind();
}
else
{
int max = 0;
if (int.TryParse(tbxHowMany.Text, out max))
{
GridView1.DataSource = GetMaterialData(Session["MemberKey"].ToString(), radTOP.SelectedItem.Value, "Primary", max);
GridView1.DataBind();
}
}
}
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
}
}
나는 gridview를 채우기 위해 사용하는 linq가 테이크를 사용하므로, 정렬이 실행될 때 데이터가 손실 될 수 있다고 생각합니다.
누군가 올바른 방향으로 나를 가리켜 주시겠습니까? 마찬가지로, 내가 행운을 빕니다 및 rowediting와 비슷한 문제가 발생할 것입니다 그래서 만약 내가 원하는 결과를 달성하기위한 제안을 할 수 있다면, 나는 가장 감사하게 될 것입니다 ... 사실, 당신은 내 지역에서 축제 음료에 가입 할 환영합니다. !
