Making Your own bar chart (new idea):-
private void Window_Loaded(object sender, RoutedEventArgs e)
{
double[] array = {40.1,20.2,59.3,11.20,45.25};
for(int i=0;i<array.Length;i++)
{
Label l = new Label();
l.Margin = new Thickness(68+(i)*45,4,0,0);
l.Height = array[i]*5;
l.Width = 45;
l.Content = i.ToString();
if(i%2==0)
l.Background = Brushes.Red;
else
l.Background = Brushes.Blue;
l.BorderBrush = Brushes.Gray;
l.Content = array[i];
l.BorderThickness = new Thickness(2, 2, 2, 2);
l.VerticalAlignment = System.Windows.VerticalAlignment.Bottom;
l.HorizontalAlignment = HorizontalAlignment.Left;
outergrid.Children.Add(l);
}
}
To get database name and tables in particular database:-
SqlCommand cmd = new SqlCommand();
string str="Data Source=.\\sqlexpress; Integrated Security=True;";
SqlConnection con = new SqlConnection(str);
con.Open();
DataTable dt = con.GetSchema("DataBases");
foreach (DataRow row in dt.Rows)
{
Response.Write("<br>Database: " + row["database_name"]);
}
con.Close();
str = "Data Source=.\\sqlexpress;Initial Catalog=testing;Integrated Security=True";
con = new SqlConnection(str);
con.Open();
dt = con.GetSchema("Tables");
foreach (DataRow row in dt.Rows)
{
Response.Write("<br>Table: " + row["table_name"]);
}
con.Close();
Making dynamic table using C# where ever you want :-
Place the Label on the page where you want to place table. Make its ID lblForTable.
C# code:-
lblForTable.Text="<table border=1>";
for(int i=0;i<noOfRows;i++)
{
lblForTable.Text+="<tr>";
for(int j=0;j<noOfCols;j++)
lblForTable.Text+="<td>"+//Place your Dynamic content here,say (i+j) +"</td>";
lblForTable.Text+="</tr>";
}
lblForTable.Text+="</table>";
Making Your own Slide Show displaying images of a folder
