Howto place data from DataSet to List


Howto place data from DataSet to List

like below fixes the issue You are adding the current object, this, to the list and then, in subsequent iterations, you are modifying the same object (via the this reference) before adding it, again, to the list. This means you end up with a list containing the same object (the this object) over and over again. Its values will reflect only the latest values applied to it.
What you want to do instead is add new instances of ProductsDAL to the list each time, i.e. instead of modiying this, instead you should create a new ProductsDAL, set its state and add that to the list.

help you fix your problem I'm pretty sure that CSVReader (CodeProject) can read to DataTable.
code :
        DataTable table = new DataTable();
        // set up schema... (Columns.Add)
        using(TextReader text = File.OpenText(path))
        using(CsvReader csv = new CsvReader(text, hasHeaders)) {
            table.Load(csv);
        }

To fix this issue I have got the following join: , You need to use a correlated subquery, for example add the following:
code :
WHERE gk1.DATUM = (SELECT MAX(SUB.DATUM) FROM tGrundkondition SUB
    WHERE SUB.tLieferant_kLieferant = l.kLieferant)

I think the issue was by ths following , If both the tablix and graph are representing the same data (even from different perspectives), then I would suggest using the same dataset for both the tablix and the graph.

I hope this helps . We have an ASP.Net / VB.Net web form containing a drop down list in the markup of the aspx file. There is also a DataSet created with the DataSet designer.
code :
<asp:DropDownList ID="MyDropDownList" runat="server" DataTextField="SomeString" DataValueField="SomeUniqueId" />
protected void Page_Load(object sender, EventArgs e)
{
    var myDataSet = new DataSet(); // replace with your dataset
    MyDropDownList.DataSource = myDataSet;
    MyDropDownList.DataBind();
}
Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load
    Dim aDataSet As DataSet
    MyDropDownList.DataSource = aDataSet
    MyDropDownList.DataBind()
End Sub
<body>
    <form id="form1" runat="server">
        <div>
            Fruits
            <asp:DropDownList ID="DropDownListWithFruits" runat="server" DataTextField="FruitName" DataValueField="FruitId" />
        </div>
    </form>
</body>
protected void Page_Load(object sender, EventArgs e)
{
    var myDataSet = new DataSet();
    var table1 = new DataTable();
    table1.Columns.Add("FruitName");
    table1.Columns.Add("FruitId");
    table1.Rows.Add("Apple", 1);
    table1.Rows.Add("Banana", 2);
    table1.Rows.Add("Grapefruit", 3);

    myDataSet.Tables.Add(table1);

    DropDownListWithFruits.DataSource = myDataSet;
    DropDownListWithFruits.DataBind();
}

wish help you to fix your issue I want to copy all my data from database to generic list to which i will bind to gridview. but i won't be able to do it . what i am doing is as : , You should create class that will hold your row data:
code :
public class Item
{
    public string Name { get; set; }
    public string Age { get; set; }
    public string Salary { get; set; }
    public string City { get; set; }
}
public List<Item> fillgridviewDAL()
{
    List<Item> NameList = (from r in dataset.Tables["MyTableName"].AsEnumerable()
                           select new Item {
                               Name = r.Field<string>("name"),
                               Age = r.Field<string>("age"),
                               Salary = r.Field<string>("salary"),
                               City = r.Field<string>("city")
                           }).ToList();
    return NameList;
}
