Right click on the project -> Add new Item -> Select Master Page -> Click Add.

I'm guessing your problem is more how do you change each existing page to use the new master page? After adding the master page, go into each existing page and add MasterPageFile="~/Site1.Master" into the Page declaration at the top. After that, remove you , , tags etc from the page, add the relevant <asp:content xmlns:asp="#unknown"> tags and move the required code into each content area.

Hello,

I have placed a table of 2 columns 5 rows and 4 dropdown lists and 2 textboxes in its columns. Out of these 4 dropdown lists, i have enabled autopostback property; but when i run the page and changes/select the options of this dropdown list; this control's postback do'nt fire immediately; it takes so many minutes and/or seems like hang the page. It is not on a specific item; sometime it works fast and sometime i select the items it again seems like hand / not postbacked.

Why this is like so; and how to resolve it.

Thanks & Regards

It may cause of very heavy viewstate text in your page. Check your page view source if yes then
google for "save viewstate in database"

What would happen if you changed the row to a single cell with a user control that has the dropdowns. You cound wrap the user control in an update panel?

Well, your first step is probably to look at the js that ASP.NET generates, then work out how to write something that will hook into it.

SMS Gateways

Hi Guys,

I need to send and receive SMS through my asp.net application based on some changes in database
(SQL Server 2005). I am going to have one continuously monitoring process which will check any database changes and will then send the SMS to appropriate user. The process will also listen to the port if there is any new received SMS.

I have come accross many gateways available in the market like
1) Ozeki (http://www.ozekisms.com/index.php?owpn=230)
2) http://www.clickatell.com/developers/api_soap.php
3) esendex
etc. (I will not bore you with the list Smile | :)

)

So far, I liked "Ozeki". But I want to know if anybody knows any better gateway which has been used in your applications earlier. I would also like to know your experiences on Ozeki if any of you have used it.
Your inputs will be a big help.

Thanks in advance.

Hi
In asp.net website when writting inside textboxes html tags or single cote an error is generated " potentially dangerous Request.Form value was detected from the client ".
I used to put in page directive of master page validaterequest=false and everything is ok.

I have met someone who told me that this is not secure and can cause sql injection (but iam using stored procedures) or script injection.

I have also read about enabling "Debug=true" directive at the top of the file that generated the error

I also know that we can encode our text values and save them in sql as encoded using Server.HtmlEncode(txtName.Text));
but do i have in this case to write Server.HtmlEncode and decode when reading for every textbox i have and does it have any influence on loading time, does it take time????

plz advice and thanks

first thing using validaterequest=false is not secure is right. It may cause of script injection but sql injection can be used. Server.HtmlEncode will protect you for script injection. about the loading time you can check your self as:
add:
<system.web>
<trace> enabled="true"
mostRecent="true"
requestLimit="50" />

In your web.config file and...
Then open trace.axd file by write in end of your url like:

Hi Nyoti

Thanks for your reply

But actually i didn't specified that my page is a dynamic page which is created at runtime and now i want to access a usercontrol's hidden input in other usercontrol.

SO the main problem is that page in which the usercontrols are show is dynamic and usercontrols are also dynamically loaded onto the page.

OK.

In this case, you can add dynamic events at the time of Control Creation and write handlers for them.

Re: Access input hidden value of a usercontrol in another usercontrol

Nyoti Rukadikar23-Apr-09 4:18

ok. Are you able to execute the events in your user controls?

If not, then you need to do something like this.
EventInfo SomeEvent = AnyControlInYourUserControl.GetType ().GetEvent("Click");
SomeEvent .AddEventHandler(AnyControlInYourUserControl, new EventHandler( this.AnyControlInYourUserControl_Click));
Write a handler for this.

But I think, you are already executing postback, however, since the page is dynamically being created, on post back you are loosing the value of the hidden variable. So in the event handler function above you can store the value of the variable in the session and then can access it.

I am sorry, if I misunderstood anything. I will post the code tonight if you want.

Thanks,
Nyoti

Hi Nyoti,
No no you've been of grr8 help but actually i'm not able to get the usercontrol

i mean the page is dynamic and controls in it are dynamic.
Ok i'll explain it ..
I've a dynamic page which has a 2 panels in each panel there are usercontrols 1 control shows the articles and other has a review
for every article user can post review and that review details are stored in database now problem is when i'm saving the details i need the article id so that i can link the reviews with the articles. i've already taken a input hidden value in which i'm storing articleid in codebehind
now i want that article id in the review usercontrol so on submit button click i can save the article id (uniquidentifier) into database along with review details.

Hope now you can get exactly what i'm trying to do...

Now i want the usercontrol id so i can findcontrol inside it and can find the htmlinputhidden value..

thanks in advance.
I'm sure you'll be ready with solution to this problem.
Sorry to trouble you so much but really stuck with this problem so favour needed.
