I have a page that shows statistics for users, this cannot be cached because each user has different statistics and there are many thus the real time query must be made.
What the way to avoid database server overload when user will click F5's to refresh or to ask different queries in short time intervals ?
I have .aspx page that page inserts the data to the database on a button click. But when i press the button it is going right. i m getting the Successfully message as " successfully inserted data". In this situation if i press "F5" or Refresh the page it is firing the button click event.
View 2 RepliesI have some asp.net pages that read and write cookie values. During the life cycle of a page it may update the cookie value and then need to read it again further in the code. What I've found is that it's not getting the latest value of the cookie until a page refresh. Is there a way around this? Here's the code I'm using to set and get the values.
public static string GetValue(SessionKey sessionKey)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix];
if (cookie == null)
return string.Empty;
return cookie[sessionKey.SessionKeyName] ?? string.Empty;
}
public static void SetValue(SessionKey sessionKey, string sessionValue)
{
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiePrefix];
if (cookie == null)
cookie = new HttpCookie(cookiePrefix);
cookie.Values[sessionKey.SessionKeyName] = sessionValue;
cookie.Expires = DateTime.Now.AddHours(1);
HttpContext.Current.Response.Cookies.Set(cookie);
}
I am currently using the brinkster hosting (Pro Package) but recently they change my hosting to the new one and after that I got an error for sometimes and my session also expired very fast. Below is the feedback from Brinkster.
Thank you for letting us know about your recent experience with your application. From what we are able to find regarding your application problems, they appear to be related to your ms access database. Due to limitations of ms access, you may want to consider updating the database running your website to mysql. A Mysql database is available to your account at no additional charge.
MS access begins to experience issues like database locks (which is what appears to be happening to your application) when there are more than 3 or 4 concurrent connections to the database for reads. MS access is also only able to have one write connection open at any given moment. MS access databases are more susceptible to corruption and data loss than database application built for large application use and Enterprise or corporate use.
When you were hosted on the previous server, your IIS application pool was getting reset many times per day. This action was in effect unlocking your ms access database from its locked state. After we moved you to the new system and raised your memory utilization limit, your application does not receive resets more than one or two times a week. I have lowered your memory utilization from 200 to 100 in an effort to have your application reset more often, unlocking your database if it has began to cause issues.
My question is, do i have a choice to avoid change my database from MS Access to MySQL? Is MS Access database really have such problem as they mension or somethingelse happen on their server?

i have problem with radiobutton is in autopostback=true.
if i check rb1 page is refresh. after using update panel also i face the same problem in my code autopostback=true is compulsary beacause some controls open depending on this option..
Here is the sample code am trying.
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" />
<div>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="conditional">
<Triggers>
<asp:PostBackTrigger ControlID="Button1" />

This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.
On button click i do action A1, like
btnAction1_Click(object sender, ImageClickEventArgs e) {
//Action 1 code
}
now ,i'll click this button. If page is refreshed after Action1 is done..request is sent again and same action is repeated.
I have a radio buttonlist in my webpage with 2 list items, when I click the 2nd list item I want to change the visibility of a text box so it wore the code
protected void rbList_SelectedIndexChanged(object sender, EventArgs e)
{
if (rbList.SelectedIndex == 0)
{
txtPresentlyUsing.Visible = false;
}
if (rbList.SelectedIndex == 1)
{
txtPresentlyUsing.Visible = true;
}
}
and its working fine but the page got refreshed how can I avoid this if I want to use ajax how can I implement it?
I have a masterpage with a timer that shows server time and refreshes every second, on the content page I have a chat program with ajax, refreshes every to second to get the last messages entered.
I have a Html TextBox and a hidden Submit Button, when user write a text, and hit the enter, I check to see if this is the enter key and then submit the message,it is working perfectly in IE, but in FireFox and Opera it show the same message twice. I think the problem is the Timer, is there any way to avoid the MasterPage timer in this particular content page?

View 1 Replieshow to make asp.net page fast render as fast as HTML page, this is my main and urgent requirement,
Acctualy My page conatins lots of data, images and videos from the database, so m facing the problem in page rendring, rendring is too slow, and client requires as fast rendring as HTML, i have studied a lot and found.....
Retrive data with the help of XML creates fast page rendring mean Retrive data from database in XML and then bind all the data in page from that XML file.
We recently migrated to v4 of .net. We are running iis 7 in integrated mode. When the site first starts its slow. I get that - it compiles for the first time. The odd thing is then we will go to certain pages and it seems to compile again. The next time i go that page its very fast. Nothing exceptional with the second page - but once that is hit the rest of the site is fast.
View 1 RepliesI have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.

View 8 RepliesI came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database development tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding.
The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?
I'm building an ASP.NET MVC site where I want to limit how often authenticated users can use some functions of the site.
Although I understand how rate-limiting works fundamentally, I can't visualize how to implement it programatically without creating a major code smell.
If it matters, all of these functions are currently expressed as Actions that only accept HTTP POST. I may eventually want to implement rate-limiting for HTTP GET functions as well, so I'm looking for a solution that works for all such circumstances.
I'm trying to get this to work. My current problem is what to do if the user wants to give the same rating that already exists. For example, an item has a rating of five, and the user wants to give it another 5 rating.
