The first step is to get data through a Stored Procedure into a DataSet. The following code gets the code into a DataSet from an SP that has just 2 select statements from the
DataTable avDaysTable = new DataTable();
DataTable avTimeTable = new DataTable();
DataSet ds = new DataSet();
SqlConnection sqlCon = new SqlConnection("server=[servername];uid=[username];pwd=[password];database=[database]");
SqlCommand cmd = new SqlCommand("GetAvailabilityDaysAndTime",sqlCon);
cmd.CommandType = CommandType.StoredProcedure;
SqlDataAdapter dAdapter = new SqlDataAdapter(cmd);
dAdapter.Fill(ds);
avDaysTable = ds.Tables[0];
avTimeTable = ds.Tables[1];
Now that we have two datatables with Days and Times, we now need to construct a dynamic table containing these. For that we first declare an empty table in the aspx page:
<asp:table CssClass="sub-heading" id="MyTable" Width="100%" Height="50%" Runat="server" Font-Size="10" Font-Name="Arial" BorderStyle="Ridge" GridLines="Both"></asp:table>
Now to build the dynamic time table, we first take the count of the columns that need to come, and first construct the header row with the number of columns.
int columnCount = avTimeTable.Rows.Count;
TableItemStyle tableStyle = new TableItemStyle();
tableStyle.HorizontalAlign = HorizontalAlign.Center;
tableStyle.VerticalAlign = VerticalAlign.Middle;
tableStyle.Width = Unit.Pixel(100);
tableStyle.CssClass = "button-editable-heading";
TableRow headerrow;
TableCell headerCell;
headerCell = new TableCell();
headerCell.Text = "";
headerrow = new TableRow();
headerrow.Cells.Add(headerCell);
for(int i=0;i<avTimeTable.Rows.Count;i++)
{
headerCell = new TableCell();
headerCell.Text = avTimeTable.Rows[i][1].ToString();
headerrow.Cells.Add(headerCell);
}
headerrow.ApplyStyle(tableStyle);
MyTable.Rows.Add(headerrow);
Next, for each of the columns in the header, we now need to add as many number of days as in the AvailabilityDays table. This will constitute the rows of the table. To each of these rows, we also need to add a Checkbox so that the availability for a day and for a particular time can be set. Finally, add these rows to the main table to complete the time table grid.
CheckBox chk;
for(int i=0;i<avDaysTable.Rows.Count;i++)
{
//add rows to first column
headerrow = new TableRow();
headerrow.ID = i.ToString();
headerCell = new TableCell();
headerCell.Text = avDaysTable.Rows[i][1].ToString();
headerCell.ApplyStyle(tableStyle);
headerrow.Cells.Add(headerCell);
for(int j=0;j<avTimeTable.Rows.Count;j++)
{
headerCell = new TableCell();
chk = new CheckBox();
chk.ID = "chk" + i.ToString() + j.ToString();;
headerCell.Controls.Add(chk);
headerrow.Cells.Add(headerCell);
}
MyTable.Rows.Add(headerrow);
}
MyTable.Rows.Add(headerrow);
Thats it. We now have a time table grid ready to take the values for any day any time. In the next article, I'll explain how we can store and retrieve values in the time table.
