Re: Need eyes for GridView weirdness - FindControl returns null when requesting a control that I know exists

d'oh.

...if you're going to try and access a control in a GridView, don't do this in RowCreated lol:

Record record = (Record)e.Row.DataItem;
TableCell cell = e.Row.Cells[2]; //<- Cell that contains my lblStatusMessage control
cell.Text = record.StatusMessage;

(The code was prototype code that I had commented out. I must have accidentally had it selected when I uncommented code that surrounded it)

...but can anyone explain why the Controls collection is mutilated when accessing the cell directly?

This happens because when you use a control(here a label) inside another control which implements "INamingContainer"( here GridView) , the ID generated becomes diferrent ( you can see that generated ID is an hierarchical name ) hence with provided ID ( here lblStatusMessage) you dont get that control.

FindControl does not locate that only because the ID value you have provided has been changed at runtime.

So assigning the cell Text as in...

Record record = (Record)e.Row.DataItem;
TableCell cell = e.Row.Cells[2]; //<- Cell that contains my lblStatusMessage control
cell.Text = record.StatusMessage;

...causes the control that is contained in that cell to be reassigned an id? That doesn't make much sense to me, but I would love to hear more detail as to why that is the case.

Whenever I comment out my assignment "cell.Text = record.StatusMessage", the e.Row.FindControl("lblStatusMessage") lookup processed like a champ.

<script type="text/javascript" language="Javascript"

//<![CDATA[
if (typeof jQuery == 'undefined') {
    document.write(unescape("%3Cscript

}//]]></script>

I found above code in CP home page, just want to know is there any benefit referring the jQuery framework from microsoft website at the first place?

JQuery has nothing to do with Microsoft, asp.net.

'jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript."

http://jquery.com/[^]

I would suggest doing a little research

Mark, sorry if the question was not clear. I know jQuery and using it from last 2 years, actually I want to ask why the jQuery file is referenced from Microsoft website instead of a local js reference.

In the code it is checked that if the file in not available at MS site then load it from a local path. Do we get any benefit doing this?

Two reasons could be Consistency, the same version can be referenced. Cache, the js file could be cached by ajax.com.

Your database design is not scalable. How do you differentiate between months, or years? Do you only expect this application to be used for one 31 day month, then never again?

You should store the date along with the number of hours.

CREATE TABLE TimeSheet
(
ID INT IDENTITY(1,1) NOT NULL,
Date DATETIME NOT NULL, --Or just DATE if using SQL Server 2008
Hours TINYINT NOT NULL
)

Serialization

Hi Guys

I am busy working on a serializer module ,and i have a quick question, lets for instance say i have a LINQ object called User, in a website I want to serialise it to a file , its marked non serializable so it will throw an exception.

Now i take that exact same object I store it in a session called "user" now if i want to call it back I simply go (User)Session[user]; and i have it back . now how does Sessions store that object so i can retrieve it back again ? Confused | :confused:

Is there maybe a way i can store this object as a byte array and recall it ?

Any help would be great

TThanx

If you don’t want to use any 3rd party tool for the conversion then try using SSRS report (.rdl file) locally, you can host the report locally (mode=local) in your website and report viewer control will render the pdf file for you.
