I guess that your problem may be in the Page_Load method:
protected void Page_Load(object sender, EventArgs e)
{
if (Session["LogedInID"] != null)
{
server = Request["id"].ToString();
tblServer.ID = "tblid";
int tblRows = Rows;
int tblCols = Columns;
tblServer = new Table();
PlaceHolder1.Controls.Add(tblServer);
if (!Page.IsPostBack)
{
CreateDynamicControls(server);
}
//CreateDynamicControls(server);
}
else
{
Response.Redirect("login.aspx");
}
}
you first set the ID property of the table and then you instantiate a new table so the ID is lost ... I did something similar in a
test project:
Table tblServer = new Table();
protected void Page_Load(object sender, EventArgs e)
{
tblServer.ID = "tblid";
tblServer = new Table();
Response.Write(tblServer.ID);
}
and there is no output from the Response.Write method
try to set your ID again after the tblServer = new Table(); line

It Works 
All i had to do was pass the form as a paremeter eg:
protected void Button3_Click(object sender, EventArgs e)
{
searchDynamicControl(this);
}
private void searchDynamicControl(Control parent)
{
......some code here
}

Hi,
I guess your using the calendar control for ASP.NET...
If so, you can use the OnSelectionChanged event to implement the behavior you want.
<asp:textbox id="TextBox1" runat="server" xmlns:asp="#unknown">
<asp:calendar id="Calendar1" runat="server" onselectionchanged="cal_SelectionChanged" xmlns:asp="#unknown">
and the code for the event is:
protected void cal_SelectionChanged(object sender, EventArgs args)
{
TextBox1.Text = Calendar1.SelectedDate.ToString();
}
Is this what you want?

in order to use a file from the server try to specify it's path using the Server.MapPath(string path) method.
This will give you the physical path of the file on the server
try this and see if it helps you.

i am using this Session["str"] where ever i need to display the username
The Problem is when i click logout
the sessions are not removed
how to clear the sessions. i want help.........

The Abandon method destroys all the objects stored in a Session object and releases their resources use ,
session.Abandon ;
or set session["str"]=null;

You are seeing browser cached version of the page. This can't be stopped effectively.

You can Clear the session or abondon the session as
Session.Abandon();
or
Session.Clear();
for back button,
You have two option
a: disable the back button
b: clear the hostory
both can be done using javascript
Cheers!!

No. No events are fired when back button is pressed.
Brij wrote: disable the back button
No reliable methods are available.

I have a checkbox that is with in a datalist which is in turn inside a panel.
I am trying to see if a checkbox was checked, to do some action.
how can I find the checkbox?
I get System.NullReferenceException: Object reference not set to an instance of an object.
Thank you.
the aspx.cs code
protected void testb_CheckedChanged(object sender, EventArgs e)
{
CheckBox chkBox = (CheckBox)Page.FindControl("chkMarkerInbox");
if (chkBox.Checked == true)
.....
//also tried this
CheckBox chkBox = (CheckBox) pnlInbox.FindControl("chkMarkerInbox");
if (chkBox.Checked == true)
....
}
Here is the sample code:
<asp:Panel id="pnlInbox" runat="server">
<asp:DataList DataKeyField="inboxID" ID="inboxDL" runat="server" OnItemCommand="DeleteInboxMessage_Click" DataSourceID="inboxDS" CellPadding="0">
<ItemTemplate>
<table border="1">
<tr>
<td>
<asp:CheckBox ID="chkMarkerInbox" runat="server" AutoPostBack="true" OnCheckedChanged="testb_CheckedChanged" />
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>
</asp:Panel>

First, you need the index of the item you need to get
CheckBox chkBox = (CheckBox) this.inboxDL.items[indexOfTheItemYouWant].findcontrol("chkMarkerInbox")
If you are getting the selectedindexchanged then:
CheckBox chkBox = (CheckBox) this.inboxDL.selectedItem.findcontrol("chkMarkerInbox")

Thanks a lot. How come with the Items it finds it and without just like:
CheckBox chkBox = (CheckBox)this.inboxDL.FindControl("chkMarkerInbox");
It doesn't.
Since it's a data list I have a several row of checkboxes
CheckBox chkBox = (CheckBox)this.inboxDL.Items[1].FindControl("chkMarkerInbox");
When I put Items[1] it only changes state when I check that item.
How do I do it when any checkbox is marked?
Thank you again.
