Cómo separar una tabla de datos por una columna y almacenarla para su uso posterior

Question

DataTable (ya ordenado por Ee ):

Title           EventDate                   EndDate 
Testing 1       3/23/2016 11:00:00 AM       3/23/2016 12:00:00 PM

Etiqueta ASP.net:

<asp:Label ID="lDates" runat="server"></asp:Label>

¿Cómo puedo codificarlo para que la tabla de datos se muestre en la etiqueta de esta manera? (Puede que no sea así, pero de alguna manera puedo separarlos por fechas y mostrarlos en diferentes lugares):

3/23:   Testing 1
        Testing 2

3/24:   Testing 9

3/29:   Testing 5
        Testing 6
        Testing 4

Answer 1

Lo hago haciendo un bucle a través de DataTable , obtengo el EventDate actual y lo compruebo con el anterior en.

Este es el código vb.net :

    ''get first date from table in format day.month - adapt to Your date format    
    Dim pDT As String = String.Format("{0:dd.MM}", dt.Rows(0)("EventDate"))
    Dim res As String = "<table cellspacing=0 cellpadding=0><tr><td style=''text-align:left;vertical-align:top;border-bottom:solid 1px gray;''>" + pDT + "</td><td style=''text-align:left;vertical-align:top;padding-bottom:10px;border-bottom:solid 1px gray;padding-left:10px;''>" + dt.Rows(0)("Title") + "<br>"
For x = 1 To dt.Rows.Count - 1
   ''get EventDate from current row
   Dim nD As String = String.Format("{0:dd.MM}", dt.Rows(x)("EventDate"))
   If nD <> pDT Then
      res += "<td></tr>"
      pDT = String.Format("{0:dd.MM}", dt.Rows(x)("EventDate"))
      res += "<tr><td style=''text-align:left;vertical-align:top;border-bottom:solid 1px gray;''>" + pDT + "</td><td style=''text-align:left;vertical-align:top;padding-bottom:10px;border-bottom:solid 1px gray;padding-left:10px;''>" + dt.Rows(x)("Title") + "<br>"
   Else
      res += dt.Rows(x)("Title") + "<br>"
   End If
Next
res += "</td></tr></table>"
lDates.Text = res

Como no uso c# , el convertidor en línea convierte el código siguiente (espero que sea la conversión correcta :():

string pDT = string.Format("{0:dd.MM}", dt.Rows[0]["EventDate"]);
                string res = "<table cellspacing=0 cellpadding=0><tr><td style=''text-align:left;vertical-align:top;border-bottom:solid 1px gray;''>" + pDT + "</td><td style=''text-align:left;vertical-align:top;padding-bottom:10px;border-bottom:solid 1px gray;padding-left:10px;''>" + dt.Rows[0]["Title"] + "<br>";
                for (int x = 1; x <= dt.Rows.Count - 1; x++)
                {
                    string nD = string.Format("{0:dd.MM}", dt.Rows[x]["EventDate"]);
                    if (nD != pDT)
                    {
                        res += "<td></tr>";
                        pDT = string.Format("{0:dd.MM}", dt.Rows[(x]["EventDate"]);
                        res += "<tr><td style=''text-align:left;vertical-align:top;border-bottom:solid 1px gray;''>" + pDT + "</td><td style=''text-align:left;vertical-align:top;padding-bottom:10px;border-bottom:solid 1px gray;padding-left:10px;''>" + dt.Rows[x]["Title"] + "<br>";
                    }
                    else
                    {
                        res += dt.Rows[x]["Title"] + "<br>";
                    }
                }
                res += "</td></tr></table>";
                lDates.Text = res;

Es un código poco sucio.

Actualizar (rellenar Repeater ):

Luego tiene que crear una nueva, vacía, DataTable y usar, casi, el mismo código, pero, en lugar de poner valores en una string , póngalos, por separado, en una nueva DataTable (con 2 columnas, una para fecha y otra para Títulos):

codebehind (vb.net):

Dim newDT As New DataTable
            newDT.Columns.Add("Date", GetType(String))
            newDT.Columns.Add("Titles", GetType(String))
            Dim pDT = String.Format("{0:dd.MM}", dt.Rows(0)("EventDate"))
            Dim titles As String = dt.Rows(0)("Title") + ","
            For x = 1 To dt.Rows.Count - 1
                Dim nD = String.Format("{0:dd.MM}", dt.Rows(x)("EventDate"))
                If pDT <> nD Then
                    titles = Mid(titles, 1, Len(titles) - 1)
                    newDT.Rows.Add({pDT, String.Join("<br>", titles.Split(",").ToArray)})
                    pDT = String.Format("{0:dd.MM}", dt.Rows(x)("EventDate"))
                    titles = dt.Rows(x)("Title") + ","
                Else
                    titles += dt.Rows(x)("Title") + ","
                End If
            Next
            titles = Mid(titles, 1, Len(titles) - 1)
            newDT.Rows.Add({pDT, String.Join("<br>", titles.Split(",").ToArray)})
            rptDate.DataSource = newDT
            rptDate.DataBind()

codebehind ( c# ) (ps No estoy seguro de que sea la conversión correcta. Lo siento, de nuevo, estoy muy, muy débil con c# :():

DataTable newDT = new DataTable();
newDT.Columns.Add("Date", typeof(string));
newDT.Columns.Add("Titles", typeof(string));
string pDT = string.Format("{0:dd.MM}", dt.Rows[0]["EventDate"]);
string titles = dt.Rows[0]("Title") + ",";
for (x = 1; x <= dt.Rows.Count - 1; x++) {
    string nD = string.Format("{0:dd.MM}", dt.Rows[0]["EventDate"]);
    if (pDT != nD) {
        titles = Strings.Mid(titles, 1, Strings.Len(titles) - 1);
        newDT.Rows.Add({
            pDT,
            string.Join("<br>", titles.Split(",").ToArray)
        });
        pDT = string.Format("{0:dd.MM}", dt.Rows[x]("EventDate"));
        titles = dt.Rows[x]("Title") + ",";
    } else {
        titles += dt.Rows[x]("Title") + ",";
    }
}
titles = Strings.Mid(titles, 1, Strings.Len(titles) - 1);
newDT.Rows.Add({
    pDT,
    string.Join("<br>", titles.Split(",").ToArray)
});
rptDate.DataSource = newDT;
rptDate.DataBind();

aspx:

<asp:Repeater runat="server" ID="rptDate">
            <HeaderTemplate>
                <table cellpadding="0" cellspacing="0">
            </HeaderTemplate>
            <ItemTemplate>
                <tr>
                    <td class="td1">
                        <%# Container.DataItem("Date")%>
                    </td>
                    <td class="td2">
                        <%# Container.DataItem("Titles")%>
                    </td>
                </tr>
            </ItemTemplate>
            <FooterTemplate>
                </table>
            </FooterTemplate>
        </asp:Repeater>

css:

.td1, .td2 {width:250px; border-bottom:solid 1px gray; text-align:left; vertical-align:top;}
.td1 {font-weight:bold;}
.td2 {font-style:italic;}

Y configurar el DataSource repetidor:

var groupedObjectList = from DataRow r in ds.Tables[0].Rows
                                group r by r.Field<DateTime>("EventDate") into g
                                select new { EventDate = g.Key, Items = g.Select(i => new { Title = i.Field<string>("Title"), Location = i.Field<string>("Location") }).ToList() };

        rptCalendar.DataSource = groupedObjectList;
        rptCalendar.DataBind();

Y el evento rptCalendar_ItemDataBound:

protected void rptCalendar_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item)
        {
            DataList itemList = ((DataList)e.Item.FindControl("dtList"));
            itemList.DataSource = ((dynamic)(e.Item.DataItem)).Items;
            itemList.DataBind();
        }
    }

Answer 3

protected void rptTeste_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        ((Label)e.Item.FindControl("lblRepeater")).Text = ((DateTime)((dynamic)(e.Item.DataItem)).EventDate).ToString("MM/dd");
    }

Answer 4

var groupedObjectList = from DataRow r in ds.Tables[0].Rows
                                  group r by r.Field<DateTime>("EventDate") into g
                                  select new { EventDate = g.Key, Items = g.ToList() };
