The answers are: "12/16/2009" and "12/11/2009".

12/15 should also come. Right? 12/13 is less than 30 and 12/15 is more.

I hope this should work.

select tbl1.date as fromDate,tbl2.date as toDate, tbl1.indicator as fromValue, tbl2.indicator as toValue from yourtable tbl1, yourtable tbl2 where tbl1.indicator < 30 and tb12.indicator > 30 and datediff(date,tbl1.date,tbl2.date) = 2

(I have not tested the query so it may give some error)

Why Duplicate entry for Product->contributor->Email

XSLT is used to transform your xml into XHTML. You can easily move into some node decendant to the current one using XPath.

Tell me what exactly you require.

I have some controls (placeholders) that I'm trying hide/show, and a button that I want to enable/disable when the button is clicked, but none of that stuff is happening. What am I not doing?

I'm doing this (both panels are hidden by default, and the button is enabled by default:

protected void buttonRetrieveData_OnClick(object sender, EventArgs e)
{
    // this stuff is NOT happening   <----------
    this.WaitPanel.Visible = true;
    this.OutputPanel.Visible = false;
    this.buttonRetrieveData.Enabled = false;
    try
    {
        blah blah blah...
    }
    catch (Exception ex)
    {
        if (ex != null) { }
    }
    finally
    {
        // this stuff IS happening - WTF?! <--------------
        this.WaitPanel.Visible = false;
        this.OutputPanel.Visible = true;
        this.buttonRetrieveData.Enabled = true;
    }
}

Does the code run (is the event being fired?)

Is the button RetrieveData in an Ajax Update panel?

Yes, it does. I even tried putting the code (that doesn't work) into the Page_Load method thinking maybe it should go there instead, but that had no effect.

No. The panels are PlaceHolder controls.

Aren't these contradictory? Whatever the case maybe, end result will be what is there in finally block. Isn't it?

The intent is that when the button is clicked, the wait panel is displayed, the output panel is hidden, and the button that fired the event is disabled. When the process is finished, the wait panel is hidden, the output panel is displayed, and the button is re-enabled.

The finally block merely ensures that the controls are returned to the desired state, no matter what happens in the try block.

I don't see how the code I posted is contradictory.

I was thinking the other way. After the event the result will always be the same.

I don't think it will work (not among the even decent ASP.Net guys so may be wrong). Since the page will not be rendered during the phase where event is getting executed. I would rather employ a javascript function which make the panels visible/hidden before the server side event is fired and then in the event hide them.

Well, I did try moving the first block into the Page_Load method, but that didn't help at all...

That will not help. In fact if it is a full postback, nothing will. Since during the event is during executed, the page will not be rendered in the browser.

50-50-90 rule: Anytime I have a 50-50 chance of getting something right, there's a 90% probability I'll get it wrong...!!

The process that is contained in the button event is fairly long, and I was considering moving it into a thread, which would be responsible for changing the controls back upon completion. Maybe that's ultimately the answer...

I assume you would have, but still I would suggest. Have you thought about having that button in a update panel and and using update panel animator? It would give a better look.

(Here I am assuming that WaitPanel must be something like those loading/working kind gifs)

Yeah, it is.

This[^] should help. And this[^] link for UpdateProgress control (sorry for incorrect control name in earlier post).

This is what impossible.

In case of client server env, everytime you request the server, you are actually posting the form with all its data to the server, and until the server processes it and returns it back, you will see a blank screen(If not using AJAX).

So, it will not show you the panels.

What you need to do, is you call the server using AJAX call, and use some javascript to show the panel in the client side.

Panels are rendered as div.
So, design the panel in server side, if you wish... (I would have dynamically created the div using Javascript), use Js to handle like this :

var panel = document.getElementById('<%=this.WaitPanel.ClientId %>');
panel.style.display = 'block'; //To hide the panel..

and to hide it again
panel.style.display = 'none';

Dont use serverside visible property, as otherwise the html will not be sent to the client.

Forgive me if I'm wrong, but, as per your sequence, the code in the finally block is getting executed in all cases, which as far as I know, is the way it is supposed to work. I don't see any reason why the code that you have highlighted should not get executed!?

You are correct. The code in the finally block will get executed no matter what happens above it.

Dinesh Mani wrote:

I don't either, hence my question - why doesn't it work?

I'm not an expect in Ajax programming, but wouldn't the flush happen only after the event execution is completed? So, in effect, the working of the first section would not be visible but would have happened.

I'm not sure on this, as said above I'm not an ajax expert either.

This isn't Ajax...

Then I don't think you can achieve this using server code. You need to hide/disable the controls using client script do the processing using server code show/enable the controls again using client script.

I ended up using ajax, and it's working as desired.

I think you must read my post on Tips section
http://www.codeproject.com/tips/47354/Common-issues-to-ASP-NET-input-controls-for-Enable.aspx[^]

In addition to that,
I dont think you require to call server to change the visibility of Panels, and Disabling a button. Rather you use Javascript to get the element and make alteration there. This will remove unnecessary postback of the control.
