Don't miss Cutting Edge June 06

Published 24 April 06 04:52 PM | despos

Scott was nice enough to point you to my 100th MSDNMag column. The column shows how to extend the GridView control to make it support multiple selection with additional client side support like the Hotmail grid. Basically, I create and persist a checkbox column on the fly and add some script code to change colors when users check and uncheck items.

In the upcoming June 06 column, I create a custom ASP.NET provider-based service to override the existing tracing subsystem and create a custom component to parse and change at will the trace output. You can select which sections to include and add new ones. You can collapse/expand the blocks and save data to a persistent medium. And more. Don't miss it--

Dear Dino ASPosito,

Can you kindly cover how to enable gridview to allow insert new records. Even in your ASP.Net Core Reference there is no workable example. Please look into it.

Hi Dino,
first let me tell you how much I appreciate your extension of the GridView. This is a feature, that I really missed.
But is it possible that there's a bug?
When handling the OnRowCreated event the yourGridView.Columns collection does not contain the AutoGeneratedCheckBoxColumn. This results in some confusion when trying to manipulate a column over its index.
Shouldn't the autoGeneratedColumn be added somewhere to the collection of the base class?
Somthing like:
base.Columns.Insert(CheckBoxColumnIndex, field);

with kind regards

matthias

well
the grid view are always saving record by record is there any way that we use all the good things in the view but we save the data at the end i mena after updating and deleting what we need locally like we used to do in the old datase adn datagrid
then we save the data using some adopter or something
thanku

Dear Dino,

I have both ASP.net2 your books : Ref.Core and Adv. but can not run this example
for test on VS.NET 2005 .If you demo this project step by step is the best for me.
thanks..

Dear Dino
i am sorry for keep asking , but i realy have aproblen in dealing with gridview
the echnique of updating records one by one in the database is not that good . as u knw we sometimes need to save a group of records together. i do not know how to do that ith the gridview.
thank u

Nice design. And it will belong to this to consider being quabeing-both what it is and the attributes which belong to it qua being.

# xanax said on May 19, 2006 02:09 PM:

Nice design. And what is thought to be easy-to show that all things areone-is not done; for what is proved by the method of setting outinstances is not that all things are one but that there is a Oneitself,-if we grant all the assumptions.

Hi. This inquiry is universal; but that the infinite is not amongsensible things, is evident from the following argument.

Cool design, but very light. thecircle is 'a plane figure'.

Nice site. movement and rest, good and bad, they assignto the originative principles, and the others to the numbers.

Hi, all!whether they are of such and such a natureor not.

# xanax said on May 19, 2006 02:10 PM:

Cool design, but very light. But besides all these varieties of causes, whether proper oraccidental, some are called causes as being able to act, others asacting; e.g.

# xanax said on May 19, 2006 02:10 PM:

Good site. But it is nothard to solve this difficulty; for we have said in our works onphysics in what sense things that come to be come to be from thatwhich is not, and in what sense from that which is.

# xanax said on May 19, 2006 02:10 PM:

Nice design. Now (1) if the 'animal' in 'the horse' and in 'man' is one and thesame, as you are with yourself, (a) how will the one in things thatexist apart be one, and how will this 'animal' escape being dividedeven from itself? Further, (b) if it is to share in 'two-footed' and'many-footed', an impossible conclusion follows; for contraryattributes will belong at the same time to it although it is one and a'this'.

Hi. And a man who is puzzledand wonders thinks himself ignorant (whence even the lover of mythis in a sense a lover of Wisdom, for the myth is composed of wonders);therefore since they philosophized order to escape from ignorance,evidently they were pursuing science in order to know, and not for anyutilitarian end.

Hi, all!This is why themathematical arts were founded in Egypt; for there the priestlycaste was allowed to be at leisure.

# xanax said on May 21, 2006 12:48 AM:

Hi, all!Judged byall the tests we have mentioned, then, the name in question falls tothe same science; this must be a science that investigates the firstprinciples and causes; for the good, i.e.

# xanax said on May 21, 2006 12:48 AM:

Nice design. Such and so many are the notions, then, which we have about Wisdomand the wise.

# xanax said on May 21, 2006 12:49 AM:

Hi, all!And experience seems pretty muchlike science and art, but really science and art come to men throughexperience; for 'experience made art', as Polus says, 'butinexperience luck.' Now art arises when from many notions gained byexperience one universal judgement about a class of objects isproduced.

Good site. For to have a judgement that when Callias was ill of thisdisease this did him good, and similarly in the case of Socrates andin many individual cases, is a matter of experience; but to judge thatit has done good to all persons of a certain constitution, markedoff in one class, when they were ill of this disease, e.g.

# xanax said on May 21, 2006 12:49 AM:

Nice site. And understanding andknowledge pursued for their own sake are found most in the knowledgeof that which is most knowable (for he who chooses to know for thesake of knowing will choose most readily that which is most trulyknowledge, and such is the knowledge of that which is mostknowable); and the first principles and the causes are mostknowable; for by reason of these, and from these, all other thingscome to be known, and not these by means of the things subordinateto them.

# xanax said on May 21, 2006 12:49 AM:

Hi. 2 Since we are seeking this knowledge, we must inquire of whatkind are the causes and the principles, the knowledge of which isWisdom.

# xanax said on May 21, 2006 12:49 AM:

Hi. ALL men by nature desire to know.
