Re: Ajax problem - ASP.NET Discussion Boards

Assuming your web service consists of one or more asmx files, all it would take IMO is one or more aspx pages that present the required information. Mind you, I haven't tried this, however I don't expect there to be any problem. You could use a database (or a static class) to hold the shared information.

Hi,

i've a GridView with 1000 rows,
one column of the grid is "Edit".

My problem is - when i'm press on some row (for ex. row mumber 600)
the page is set to the top,
and then i need to scroll and find the row that become editable.

How i can set the focus on the row that i selected (after i pressed on "Edit").

Can someone please help me?

Try using the MaintainScrollPositionOnPostBack[^] property

I've set it at Page_Init and it works great

you can just set this on the aspx page at the top in the declaration this might be a little easier.

I have a contact.aspx page

I created asp:table with rows which has txtMessage, txtEmail and btnSend controls

I placed the table within asp:updatepanel and above it I have asp:updateprogress

Now ajax seems to be working properly and updateprogress is showing

I only have one problem here

In the btnSend_Click evet, I am setting ther button enable to false which is not happening!

I also tried setting the entire table visibility to false but its not happening as well

I am not getting any error and submission is going through but without doing what I want with the button enable property

What can I do plz?

It should not happen. I tried and its working fine as expected.Can you post code.. Then it'll be better to answer.

Cheers!!

This is the code. I just need to disable the btnSend or any of the textbox

</asp:UpdatePanel>

Perhaps the snippet was not posted or formatted correctly but you appear to have the both the progress control and the button inside the update panel

I know the language. I've read a book. - _Madmatt

Yes true

Why? Is it wrong?

So how can I do it?

The progress control should not be inside the update panel. See the example here[^] and while your at it read the rest of the documentation about UpdatePanels and how to use them.

Move the button outside the update panel and use a Trigger. Once again, reading the documentation will help.

Thx for your replies

I noted your comments and changed my code accordingly but the button is not not allowing disable

Anyhow I have another question here please

How can I hide the UpdatePanel and all everything inside it when UpdateProgress is started?

And how can I show it back from the code if my try...returned error?

This my latest code

Hi,
I've asp.net 2.0 ajax enabled web site in which I used Ajax update panels in pages. Now I want to convert it into asp.net 3.5 but it gives errors for Ajax tool kit and script manager and update panel used in pages.
I don't want to remove ajax functionality from my site, so is there a way to convert them without removing ajax update panels from pages.

On my PC I've installed both VS2005 and VS2008.

Any suggestions is appreciated.

Thank

Bajrang Singh
Using .net 2.0 (VS2005)

The Version of Ajax used in 2.0 and 3.5 is different. Your web config is still linked to the 2.0, so what you can do is remove remove the dll(ajaxtoolkit) in the bin and drag and drop any control in your page and it will create the dll in the bin directory and register it in the web config and start removing the 2.0 entries in the web config and you will see at the top of your page the 2.0 and 3.5 registration is not the same, try to change.

Hope this helps

Hi All,

Is there a way to do this: if a request is from a manual item, then re-fetch the data from database, and if a request is from the other web controls, say link button, then do not re-fetch data from database.

Thanks very much.

I guess you could use __EVENTTARGET to identify the control that caused the post-back. i.e. the control that sent the current request.

http://forums.asp.net/t/1352215.aspx[^]

Cheers,
Karthik

Thanks very much for your reply, and you did point me in the right direction
Here is the trick:
Request.Params["__EVENTTARGET"].contains("xx");
xx is the control name (it's obficates, but still humna readable, such as: ctl00$AccordionMenu1$ctl15$clb0). the "AccordionMenu1" is the name of a user control, but u can but the other controls too, e.g. link button etc.

Great, you are welcome!

And, hopefully you might know this, just in case, you could get this value "ctl00$AccordionMenu1$ctl15$clb0" using <accordion_id>.ClientID (AccordionMenu1.ClientID in code-behind) in the server side or using '<%= AccordionMenu1.ClientID %>' (for use in javascript)

Cheers,
Karthik

If you are using postbacks, the simple way is to inspect the sender variable in your event handler. This identifies the control that actually triggered the postback. It really is that simple.

Hi,

i have a question regarding saving the page. Lets suppose i have one page whose contents change each time i refresh or open. Now lets say at one page, i want to save that page or I want to put that page in my favorites so that when i click that favorites link next time, it should show that saved content not the different one. Is it possible ? If yes, any idea how to make that happen ?

suchita

Usinng Browser's save and saving the webpage on your system hard disk is the only way to have same content again at later stage. Since the page changes everytime, you cannot persists to it's old state without saving it. You dont have control over it.
