AJAX is just javascript. AJAX exists without the stupid Microsoft AJAX toolkit. There is only one way to have a timer on a page - with javascript. The AJAX toolkit is just wrapping a very basic web dev task for you.

The ^ in my post is a link. Sorry, I dunno what happened, I just pasted and CP auto formatted, I must have hit space or something, I expected you'd see the URL as well as the ^ for a new window.

Did I miss the CP announcement that today was Rhetorical Question Day? Poke tongue | ;-P

The answer is that AJAX solves everything. One day it will discover the body of Jimmy Hoffa. I believe it will be found on an as yet undiscovered computing cloud.

My current plan is to wait for Gold Light, Platinum Light or maybe even hold out for Laser Light. I still don't have an IPhone and I don't care how many two inch applications are available for it. Best thing anyone ever showed me on an IPhone was this[^]. I think the guy driving the car thought up this whole cloud computing concept.

I have generated dynamic database table in
which the colums will vary as per the selection
by the end user. Now, if my table name is car which
i have generated dynamically on the button save click
event it will have its colums like: colour, gears etc.
So can i generate a dynamic form by taking the cars id
and its column name as the textbox controls on the new
form. The new generated form will also have the basic
funtionality of add, edit,delete etc. If my table is car
then to generate dynamically car.aspx form or if table
is computer then
computer.aspx should be generated.

Changing backrow colour of a gridview based up a button click

6-Feb-09 9:47

Sounds messy to me. I'd think you want to rewrite the URL, and have a common page that gets pointed to at the end of the day.

Re: Changing backrow colour of a gridview based up a button click

6-Feb-09 6:42

Hi
I have been scratching my head on this for days, but getting no where!

Using visual basic and a sqldatasource for my gridview, I need change the colour of a gridview row backcolour plus set a hidden checkbox to checked when the user clicks on an image button. I also need to grab a field value from a row in the gridview.

Now, everything works when I am on the first page, but when I page to the next page I get the following error message "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".

My image buttons are connected to an onrowcommand in the gridview tag, which checks to see which image button has been called, gets the row number and then calls the appropriate method for that button.

Does anyone have a solution to set a hidden checkbox over a number of pages, grab a field value from the gridview and change the row back colour?

Thanks

If it works only on the first page, I guess you should post some code so we can look at it.

I'd never use a SQLDataSource tho, that stuff blows.

Hi
I have managed to crack the problem in so far by adding an onclick event to the image button, but if I page back the grid is refreshed and in turn the rows that have been clicked upon are changed back. Therefore, slightly modified question - how do you maintain those rows with post back?

Thanks

You need to store the selected page somewhere ( on the URL perhaps ) so you load the correct page when you do a postback.

Custom Sort for an ASP.NET GridView

6-Feb-09 12:42

Ideally, the control does no paging and you just pass it the data for the selected page. But, either way, however you get the data for page 2, say, what is needed is to store the selected page number so you can select that data on your postback. Perhaps a better idea is to look at the code that does the selecting, and just keep the data you had before, which will be in viewstate./

How to call page using webservice

6-Feb-09 6:29

Hi
I am developing a website using Visual Basic and NetFramework 3.5, and for my gridview I would to have a custom sort.

What I am looking for to control the sort on the columns. Therefore, if a user clicks on a column and puts into order, and then clicks another column, then the first column should remain in the sort order it was put by the user. However, I need to repeat this pattern over at least 3 columns.

Can anyone help me, please? I have tried every where for an answer.

Maite, page calls a webservice and not the vice versa.

Use some kind of loop.

I have 10000 records and I want to distribute in 300 and call that function again and again till it reach to 10000.

bucause my page is expired though I write and configure all the setting for page expired. I want to increase the access to that records.

No.
For that you can simply use AJAX Implementation.

I don't think there is any use of loading 10,000 records in a page. Use Filter to minimize the records that would also helps you to improve performance.

My suggestion try to minimize the records in a single time.

Good Luck Thumbs Up | :thumbsup:

Gosh - do you have any idea at all ? You want him to use AJAX to delete records using a webservice call ?
