Hi everybody,
i was wondering if we could execute the code in a button before the postback...
because i need to save data from a placeholder in a database, before the postback of the page...
can wa do that??
Thanks

This is possible using AJAX and call backs...
However, why is this necessary? Is it not possible to fix this by putting an if not isPostBack in your page load method?
|
|
|
|
|
so if i want to use ajax like you said, can you tell me plz the event in javascript that i should work with if i want to use a button?
for example, if i used a dropdownlist, i have to use onchange..
thanks for the reply
|
|
|
|
|
Um, onclick...
But i have my doubts that you really need to do this... Unless you really have a need to perform this asynchronously like this, you shouldn't...
|
|
|
|
|
the thing is, i have a variable session that i increment each time i push the button... but the problem is that i have to add the controls in the load_page so i can't lose them.. so when i push the button like i said, the controls are being added again because the init and the load are executed before the button event..
see what i mean??

in your load_page wrap your control adding logic inside a
if (!IsPostback) {
}
So it only executes when it's not a postback. Problem solved.

Dear All,
How I can update multiple rows (with multiple column) , Values are from another Table.
Pls reply URgent
|
|
|
|
|
INSERT INTO TableA (AColumn)<br />
SELECT AColumn<br />
FROM TableB
|
|
|
|
|
I think its better to use a cursor, it is faster too.
|
|
|
|
|
Umm, maybe better by some standards, but definately not faster. If you'll check your SQL to English dictionary, you'll see that "cursor" means "slow as hell."

Hi Friends,
I have two things that I am running short of ideas on how to solve.
I am working on medium sized search form where in I will have to do
considerable validations befor it submits the form.
1).I have to put a validation on a text box ( _txtVIN ) such that it
min and max charecters should be 8. In other words user shouldn't be
able to enter more than 8 charecters of the total VIN numner. At the
same user must enter 8 charecters if at all he eneters some thing in
the text field. I have put the max length property to put a cap on the
number of charectors entered. But no clue how do I do it in the case
min of 8 charecters?
2). I have 3 text boxes. I need to make sure that atleast one filed has
the text in it before it submits the form. In other words user must
enter atleast a value in any of the text boxes. I am not sure what
control would do best to do this?
say _txtYear, _txtMake, _txtModel and the form shoudln't submit unless
user provides atleast a value in the respective fileds.
Any inputs is greatly appreciated,
Thanks,
-L

1.) Use a RegularExpressionValidator with a regex like "\w{8}" or something.
2.) There is a RequiredFieldValidator, but that's based on one control at a time. You could probably make a custom one that attaches to all three. You can write some javascript on your submit button to prevent it from submitting, or you can just check the text boxes in your server side code.
|

Ok I will try providing a regexp for the first one and Yeah thats what kind I thought to do the server side code. I thought there has been some thing that I am not aware of so just posted here.
Thank you for the reply,

Hi,
I’m try to find an easy efficient way to generate my web pages dynamically from an xml/text file.
What exactly I want?
I want that whenever a pages is loaded it will go and read an xml/text file which will include the style of the page (tables,div, web controls, etc) and will build the page according to that. Meaning that initially the page (“default.aspx”) has no html on it and its entire html is built on the fly, per request. Please keep in mind that that text/xml file may include names of webcontrols that will have to be added to the page as will and will render themselves.
In a nutshell, I’m trying to find a way to inject to an aspx file its “hard core” html (the html which exist at design time in the aspx file) before its start to load and render itself. Please keep in mind that I cannot/don’t want to start creating those files on the fly, hence, no file IO writing.
I there any simple way to implement such a thing?
I’m working with .NET 2.0
Any idea would be great,
thanks,
Ori.

You need some kind of xslt file(s) to change your xml to html. You could then load up your xml at runtime, bind it to an xml view control along with your xslt.

Hi,
Using the Fileupload control in asp.net 2.0, how is it possible to make the control show only certain file types. i.e. .xls.txt...
Thanks

It's not. That's controlled by the browser.

In IIS administration, in the properties form for your website, they should see a tab called asp.net. On this tab you can specify which version of .net your site should run under.

Hello,
The target server is a remote one that I do not have access to... so how do I configure the IIS to run my intended version?
|
|

|

Somebody must have access to it- get them to do it
