Hi,
I'm developping an asp.net application and i ran to the following problem.
When i press an add button in the aspx page I want to store date in an
datatable. The datatable is created in a seperated class, but every time I
click the button only the last item I added is in that table.
Is this because on the button click a new object of the class is created on
every button click? Is there anyone who could help me to fix the problem?
How can I store the info in the class??
aspx-file
private Tabelletje t = new Tabelletje();
private void Button1_Click(object sender, System.EventArgs e)
{
this.DataGrid1.DataSource =
t.insertResoureInDataTable(Int32.Parse(this.TextBo x1.Text),Int32.Parse(this.
TextBox2.Text));
this.DataGrid1.DataBind();
}
class
public class Tabelletje
{
private DataSet ds;
private DataTable table;
private DataColumn col;
private DataRow row;
public Tabelletje()
{
this.createDataTableResources();
}
public void createDataTableResources()
{
ds = new DataSet();
table = new DataTable("test");
col = new DataColumn();
col.DataType = System.Type.GetType("System.Int32");
col.ColumnName = "resID";
table.Columns.Add(col);
col = new DataColumn();
col.DataType = System.Type.GetType("System.Int32");
col.ColumnName = "evrAantal";
table.Columns.Add(col);
ds.Tables.Add(table);
}
public DataSet insertResoureInDataTable(int resID, int aantal)
{
row = table.NewRow();
row["resID"] = resID;
row["evrAantal"] = aantal;
table.Rows.Add(row);
return ds;
}
}
thx
