Yes you can dynamically load User control for Peformance improvement. Even I will suggest you look into Partial Page Caching which will improve your site peroformance a lot.

Thanks !

Hi,

I have one server application and one client application. Server application directly connected to the database. Client application uses web service.
I am using Cache in my client application. I am using Web Service fetching Records from Server application Storing into the cache. With the help of that cache I am performing some updation on the fetched data and update the cache.(Not updating database).

Now if client application stop or end by any condition(Failure of power supply). If I restart the application i will get the again the same data as well as newly added data from server application.

Now I want save previously updated data as well as newly added data into cache.

From Where Should I get the previous data if the power failure happens?.

Is there any other solution for that.

Thanks,
sjs

If I understand you correctly, the cache is memory only on the client, so if it is powered down its gone. If it is a true client app (NOT a web page) you could write the cache out to disk each time it changed (probably only the changed bits) and reload it at start up.

Hi to All,

I am planning to create a new web site in my free times. So that I can learn, in a productive way.

Now, since I am a beginner in ASP.NET (I have worked on VB.NET earlier)....I need certain help in starting up the project.

What I mean is, like certain points or tips or tricks or measures , we need to take care in initial point of doing any project....Please advice me those,if any, in ASP.NET projects...or point me out those places where I need to take care of it initially, so that later on I needn't to Re-Do everything, for any kind of change.
Example: say for scalability of the project, I need to beak my project in modules, so that any change can be updated easily....something like that...

Thanks in advance.

You'd do well to work out what parts of your page will appear on all pages, and put them in a master page. Then as you create parts of pages, you'd do well to consider controls that might appear on more than one page, and create them as user controls. You'd also do well to create your own base page class, which will give you access to things you commonly use. The first thing I add to such a base class, is access to a strongly typed version of the master page.

I don't think there are any. Just use whichever language you feel comfortable with, as both are fully supported in ASP.NET.

As someone else said, VB.NET and C# both compile to the same intermediate language. There's no reason to choose one over the other, except personal preference. In ASP.NET you can actually write some pages in one and some in the other, if you wanted to, but I don't recommend it. Just use what you are comfortable with.

That's an excellent tip, Christian. I'll use it myself. But could you clarify what you mean by "access to a strongly typed version of the master page?" Specifically, what makes a Master Page "strongly typed?"

You could use regular expressions to do this.

Use the WebBrowser control that comes with .NET. You can use the WebBrowser.Document.Images collection to get the list of image tags in the html page.

WebBrowse1.Navigate("c:\mypage.html");

List<string> images = new List<string>();

HtmlElementCollection elements = WebBrowser1.Document.Images;

foreach(HtmlElement e in elements) {
    images.Add(e.Attributes("id");
}

Paging in DataList

I tried paging in ASPNET. My code get the lists from the database using stored procedure with entire records. Then, according to the number of pages, the page number should be displayed. I need only limited number of page numbers to be shown in a page.
When, I click next button, next set of page number should be displayed. My stored procedure will return dataset.
This is my code for Paging..

private void doPaging()
{

DataTable dt = new DataTable();
dt.Columns.Add("PageIndex");
dt.Columns.Add("PageText");
for (int i = 0; i <= totalpage; i++)
{
DataRow dr = dt.NewRow();
dr[0] = i;
dr[1] = i + 1;
dt.Rows.Add(dr);
}

dlPaging.DataSource = dt;
dlPaging.DataBind();
}
This code will display all page numbers once in a page.. Instead I need only 5 page numbers should display once. When I click next button, next 5 page numbers should be displayed

This is messy. Why do you need a datasource made up of a data table to do this ? A List of numbers is a viable data source. Of course, you're stepping from 0 to the number of pages, you need to change the code to only loop through the numbers you want to show. That seems obvious to me.

I don't understand. You said you wanted to only show 5 numbers, so I said then write code to only show those.
