View 6 RepliesI have an SP in backend that retreives multiple recordset/DataTable where each recordset/Datatable contains 10 records and 8 columns.
The Count of recordset/Datatable differs based on parameters.
The SP retreives Data in nearly 0.01 seconds.
I have been displaying the records by looping each Datatable and each record in DataGrid Template Control, this way the page loads very slowly.
Can some one please suggest me on how to display/Load the data more efficiently and faster in front end ASP.NET 2.0?
Can I perform some Multithreading to display records from different datatables?

View 1 Replieshow to improve the performance of dynamically load user control
View 1 RepliesI was discussing load-balancing with a colleague at lunch. I admit that I know very little about this topic. We were discussing the various ways of maintaing session in a ASP.NET application -- none of which suited the high performance load balancing that he was looking for. What about Silverlight? says I. As far as I know it is stateless, you've got the app running in the browser and you've got services on the server that feed/process data. Does Silverlight totally negate the need for Session state management? Is it more friendly to load-balancing? Is it something in between?

I am working on a ASP.NET 2.0 application. It is hosted on IIS 6 on Windows 2003 server.
Few pages have jpeg images (around 50 images and 50 KB each). It takes long time to load the page for the first time. But when i open the same page for the second or third time it is faster.
why does a web page take long time to load for the first time?
Is it cached somewhere when it loads for the first time? Do we have any control over it?
Issue:
As my pages are taking time to load first time.
So user has to wait till full page gets loaded and thats irritating . Was this the reason MVC was evolved?
Solution :Should i use partial rendering on all pages including home page, and all forms getting called from home page.
So even if half page is loaded thats less frustrating
For Partial rendering what i plan is : i will put Scriptmanager with Enable partial renderingand update panel for half part of page.
So that user dont have to wait for full page to load.
Is my plan correct? Problem is i cannot regenerate page load issue every time.

i am having the problem that i am using datareader to get contents in my asp.net page.But the page takes a lot of time to load.How to decrease the loading time of the apage and increase the performance of my page.
View 1 RepliesI am interesting on log down the recent 100 visitors around the world whom have visited to my website and display their country information and IP address on the website developed by Silverlight platform.
Where can I get accurate data for detecting the visitors' IP address and geo-location information?
I have this situation where I need to display a bunch of files pulled from a Sharepoint site in a Silverlight application. I use a WCF service to get the data from the Sharepoint site.
So what I have is file names with their corresponding extensions. What I need to do is, display the files in the Silverlight application with their corresponding file type icon and file name. The following is the Heirarchical data template I use to display the files in the Silverlight application.
<sdk:HierarchicalDataTemplate x:Key="FileTemplate">
<StackPanel Orientation="Vertical">
<Image x:Name="imgFile" Source="{Binding FileImage}" Height="35" ></Image>
<TextBlock x:Name="txtFile" Text="{Binding FileName}"></TextBlock>
</StackPanel>
</sdk:HierarchicalDataTemplate>
Where FileImage and FileName are strings.
PS: The reason I don't have file type and size is because I using Sharepoint web services and XMLReader to get the information about the files.
I need to do to the following:
Find if the current time falls within hourly ranges and display the start hour and end hour of that range in labels.
Examples:
If the current time is 8:46am, label startTime would return "8am" and label endTime would return "9am"
If the current time is 10:01pm, label startTime returns "10pm" and label endTime returns "11pm"
If the current time is 12:59am, label startTime returns "12am" and label endTime returns "1am"
I have been working with the C# TimeRange class but not getting what I need.
I have made sample code to display data in griview on page load. Evrything is wrkng without error but my page is coming blank as no data is shown
Code:
// Class Database for various methods
public class TestClass
{
private string cnstr = ConfigurationManager.ConnectionStrings["test"].ConnectionString;
private string sql="";
public DataTable Fetch()
{
string sql = "select * from item";
SqlDataAdapter da = new SqlDataAdapter(sql, cnstr);
DataTable dt = new DataTable();
da.Fill(dt);
return dt;
}
}
//Code Behind in Web Page. gdv1 name given to gridview
public partial class _Default : System.Web.UI.Page
{
TestClass tcls = new TestClass();
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
FiillItemInGrid();
}
}
private void FiillItemInGrid()
{
DataTable dtitem = tcls.Fetch();
if (dtitem.Rows.Count > 0)
{
gdv1.DataSource = dtitem;
gdv1.DataBind();
gdv1.Visible = true;
}
else
{
dtitem.Rows.Add(dtitem.NewRow());
gdv1.DataSource = dtitem;
gdv1.DataBind();
int totalcolums = gdv1.Rows[0].Cells.Count;
gdv1.Rows[0].Cells.Clear();
gdv1.Rows[0].Cells.Add(new TableCell());
gdv1.Rows[0].Cells[0].ColumnSpan = totalcolums;
gdv1.Rows[0].Cells[0].Text = "No Record Found";
}
}
}
Working in this way still no data is populated.
We need to visualize the number of forms submitted over a 2 week period where it is broken down by day/hour.
I have the query returning data such as:
My question is, how do I tell MS chart to display this data? When I bind it I get the following:
I'd like it to expand out and show the hours between the dates.
We have one Asp.net application developed using framework 2.0 with C#,Sql and AJAX. The application is running live from past 2 years almost. All the times users will be facing kind of strange problem, reporting some junk data will be displayed on the browser some times. When they refresh the page or reopen the browser, it will display the correct information.
For Eg. We have a stored procedure which returns months between 2 dates, if we pass 2 dates as '01/04/2010' and '30/06/2010' then procedure will return 'APR,MAY,JUN'.
Once case we have noticed where it has returned and displayed as MAY,JUN,JUL,AUG which is not possible. Once we refresh or reopen the page it displays the correct information.
This is one ex. whereas we have some other page also where we get unwanted values like that.
I have a query like i want to show the time information in custom format like(1min 06sec) from date .I have a filed Duration in database and when i am binding my data control then in item i want to display in above format(1min 06 sec),so is it possible?
View 3 RepliesI have a ListView that populates and displays a user's data (via a profile system in VWD 2008) during Page_Load and also when I go from the EditItemTemplate to the ItemTemplate.
When I go to the edit screen again, my DropDownList and RadioButtonList controls display the first items in the corresponding tables instead of the correct profile values.
I don't understand why the controls populate correctly the first and second times but not on the third time (that's right, the third time is NOT a charm).

I am trying to get my repeater to display information 10 records at a time for a single page with the user having the option to press next to view the next 10 pages or previous to review the previous 10 records with the option to skip pages by clicking the navigation links 1 | 2 | 3 | 4 | 5 is this possible?
Does it have to be alot of code as I have done it sort of already with an array and 5 repeaters? do arrays such as string[] a work when being hosted?
I am using a repeater control, and in that one of the item, displays a time value that it retrieves from a database, the issue now is, that i want the data to get processed eg, todays date [ minus ] the date that was retrieved from the database. How can i go about this?
I am expecting to use the vb code behind to process the data, and then display it in the repeater control pragmatically for each corresponding record that is displayed.

I have a datetime column in a database that stores the date like like this - 2011-02-27 16:00:00.000
I only want to display the time in a gridview, and need to display it in this fromat "4.00pm" . I'm using template fields to write the date and time to the gridview like this...

Does anyone know how I can out just the time like this "4.00pm"?
I would like to display time difference between previous row in GridView.
I prefer creating new Column in SQL, but I can't come up with getting value from "last row" in SQL statement.
The reason is that I would like to have Total hours.

1 | 1/1/2010 1:00:00 am |
2 | 1/1/2010 2:00:00 am | 1:00

Total 3:00
