Hi ,
I need to create a page that has databound controls . eg.
Say i have a row with the following columns
1. TrackKey VARCHAR(50)
2. State VARCHAR(50)
3. Reason VARCHAR(50)
4. DateChanged DATETIME
------------------------------------------------------------
Now for each row in the table, the controls should be like this
1. TrackKey - Label
2. State - dropdownlist
3. Reason textbox
4. DateChanged - 3 dropdownlists [years, months , days]
---------------------------------------------------------------
I am able to dynamically load these controls, but due to postback i cannot save the information that changed.
can anyone give me some advice on how to change this ?
here is my code for loading:
void GenerateList()
{
// This method will generate a table for editing states
// Dataset for storing values
DataSet setGetTrackings = new DataSet();
// In the grid - the controls
Label TrackKey = new Label();
DropDownList SetState = new DropDownList();
TextBox reason = new TextBox();
DropDownList Days = new DropDownList();
DropDownList Months = new DropDownList();
DropDownList Years = new DropDownList();
HtmlTableCell htmlCell = null;
HtmlTableRow htmlRow = null;
HandleStates entry = new HandleStates();
// finally we will count the rows for inserting
int rowcount = 2;
int IndexCount = 0;
//Set the tables.
if (setGetTrackings != null && setGetTrackings.Tables.Count > 0)
{
foreach (DataRow row in setGetTrackings.Tables[0].Rows)
{
// Create the controls.
TrackKey = new Label();
SetState = new DropDownList();
htmlCell = null;
htmlRow = null;
reason = new TextBox();
Days = new DropDownList();
Months = new DropDownList();
Years = new DropDownList();
#region Populate Controls
// Set the values
TrackKey.Text = row[0].ToString();
SetState.Items.Add(row[7].ToString());
reason.TextMode = TextBoxMode.MultiLine;
// Add more Items To The DropDown
SetState.Items.Add("--New State--");
SetState.Items.Add("Visiting x Branch");
SetState.Items.Add("Visiting y Branch");
SetState.Items.Add("Received");
SetState.Items.Add("Ready To Go");
SetState.Items.Add("Not Ready To Go");
SetState.Items.Add("Submitted");
SetState.Items.Add("Acquired");
SetState.Items.Add("Denied");
// Adding attributes to the dropdown
int IDDay = 10000000 + rowcount;
int IDMonth = 11000000 + rowcount;
int IDYear = 12000000 + rowcount;
int IDTetbox = 13000000 + rowcount;
SetState.ID = rowcount.ToString();
reason.ID = IDTetbox.ToString();
Days.ID = IDDay.ToString();
Months.ID = IDMonth.ToString();
Years.ID = IDYear.ToString();
int D1 = 1;
int D2 = 32;
while (D1 < D2)
{
Days.Items.Add(D1.ToString());
D1++;
}
int M1 = 1;
int M2 = 13;
while (M1 < M2)
{
Months.Items.Add(M1.ToString());
M1++;
}
string CurrentYear = string.Format("{0:yyyy}", DateTime.Now);
int Y1 = int.Parse(CurrentYear);
int Y2 = int.Parse(CurrentYear) + 3;
while (Y1 < Y2)
{
Years.Items.Add(Y1.ToString());
Y1++;
}
