dear friends,
I have a gridview and it is within a updatepannel.I want to impliment custom pagging for this gridview and there are certain conditions for custom pagging as per my application requirement and these are as follows:
1. I run a SP and get the data and storeed in a dataset.say 100000 records i got and store in the dataset.
2. Now when I select the pageID from a dropdownlist it should not hit the database again inspite of this it should took out only 10 records at a time from the dataset which was already filled and stored in the dataset when the page is loaded firsttime.
Here I am facing 2 major problems
1. since i am using updatepannel pagging is very slow and i cann't remove the updatepannel in this moment due to application requirement.
2. Cannot findout the proper code in this sinarion for handle custom pagging in codebehind using dataset,dataview or datatable.Because I cannot use a SP for pagging due to application requirement so only I hv to handle it in codebehind.
********************* Please help this is urgent!!! *********************
Thanks & Regards

Hi Bikash,
You have to look on Sys.WebForms.PageRequestManager class. Check the MSDN Ref^[^]
Even, I went through the similar problem for maintaining the Grid Scroll Position inside the update Panel. I have written one article on this, Hope this will help you, MMaintain GridView Scroll Position and Header Inside Update Panel[^]
Let me know any other issue.

Now i have a button in the content page which uses server.transfer method to transfer control to another file along with data. But i need to do open the page in a new window. Is there any option to do it so. If we assign form's target to blank will it open in a new window. If so how to assign target value of the form element in a content page button click.

actually i want to create a search engine for my website which will search all the data within site static as well as dynamic.
I am facing a problem when i want to search dynamic data which is generated by querystring.
I have used webClent's downloaddata method to access data from particular page, but it only searchs the entire folder of my website.
It searches dynamic data but in result page it shows wrong link.Is there any way to access all the links or anchor tag from a page having querystring and passes to webclient for accessing the data and show in result page..I hope that everyone can understand my problem and requirement..
Regards

If your content is dynamically generated, then you need to search the content it is generated by. If it's static, then you probably still want to put it in a DB, that's waht databases are good at. It sounds to me like your issue is taking the content you find, and correctly linking to the page that was found. I am not sure why this is, but it indicates an issue in your data structure.
the cheats way, nowadays, is to use google to search your site.

What I am working on is creating a custom Asp config file to update the site configuration without using the web.config file. I was planning to use my site's existing cacheManager to hold new configuration changes and have a dependency setup on the path to the file, or file itself. The objectives of this are as follows:
1. Not have the site automatically restart to read new changes made like the default web.config file does.
2. Create a cache dependency so that once the custom config file has been changed, or touched, it's will automatically invalidate the cache and on next config item read use the new config properties for all logged in and new users.
Now, I do not know if there is something already built into the .NET framework that I can use or if this is something I must implement myself.
If anyone can provide me with useful links or ideas that would be great!
Thanks,
Steve

I am not aware of anything built-in. You have to create your own custom files and classes to read it.

Hello All,
I have a question that I think I did perform due diligence on finding an answer before having to interupt your day. I am at a lost, so here goes.
I have an internal application that users requested I extend it's features by allowing a user to upload a file that anyone can look at by selecting it from a list.
I utilized the FileUpload Control with extreme ease and that this part is working great (uploading the files and saving them to the hard drive.) After this I have hit a wall.
I want the user to be able to select a saved file and have it displayed in the aspx page with the correct external application (Word for docs and txt files, and anything for pdf files. I allow the upload of DOC and PDF files). I have not found a way to do this.
If anyone can point me in the right direction, I will greatly appreciate it.
Again, sorry to bug you guys but I am lost.

If you do a response.write and set the header type correctly, then they will be able to view those files, provided they have acrobat and word installed.

I dont see any point in implementing such thing. because if you have atleast one samrt user then...
User can alway take a screen shot and save it.
User can use 3rd party browser which are not following that policy.
User can save the page by writing some script, without opening it in web browser.
User can copy-paste text and take a screen shot of your images.
User can print out and make a same page, by writting a same text or creating a same images.
User can copy the contents from "Temp Internet Files" folder.
So I think if your information is that much sensitive then just dont display it. otherwise you cannot prevent users to copy something.

I would say if you do that, it would end up looking rude at the user.

My requirement is to track pages in a ASP.NET Website.
The user should not be allowed to type some URL and go to pages of sites without logging in..
How to do that in ASP.NET 
|
|
|
|
|
When your user logged in you have to set some "Session" variable. and in all the other pages in the Page_Load event you have to check wether that variable has been set or not. if not then redirect the user to Login Page.
If you dont know how to use Session in asp.net then, you can search for article in Code Project. there is one nice article by Abhijit.

Hi,
we have a team of 5 to 7 programmers working on a single asp.net project. And we are using visual source safe for team management here. We have one asp.net website and one associated class library whose dll is added as a reference in the website.
The problem is when i want to debug i can debug pages from website very easily but when i come a point where i m accessing some routine through object of a class library it does not allow me to debug into that class of class library although i have added its dll as a reference in the website.
Second thing is when i make any change in any of the classes of class library it does not allow me to update or re-build the dll again through source safe.
Does anyone have any suggestions on it? am i missing something here or going wrong somewhere ?
Pls answer as this is the first time we are implementing source safe and that too for a very critical project.
|
|
|
|
|
Hi
Dont add dll to source safe only add classes on source safe and let others to take latest version at their end and than build at their end.
We also went through same problem

|

Thanx for the solution ... will definately try it out .... and reply for the same

Hi,
i try to use the Calendar control in a SharePoint-Webpart. Everything looks fine, except that i cannot use any button within the control or select any date.
I create an instance of the calendar within the CreateChildControls-EventHandler, I set my styles in the PreRender-Eevent, and render the Calendar.
Calendar calendarControl;
protected override void CreateChildControls()
{
calendarControl = new Calendar();
this.Controls.Add(calendarControl);
SetStyles();
}
public override void RenderControl(HtmlTextWriter writer)
{
calendarControl.RenderControl(writer);
}
private void SetStyles()
{
calendarControl.Style.Add("vertical-align", "middle");
calendarControl.BackColor = Color.WhiteSmoke;
calendarControl.NextMonthText = "Next";
calendarControl.PrevMonthText = "Prev";
calendarControl.Style.Add("float", "left");
calendarControl.Style.Add("margin-right", "30px");
calendarControl.TodayDayStyle.BackColor = Color.LightBlue;
calendarControl.SelectorStyle.BackColor = Color.Wheat;
calendarControl.DayRender += new DayRenderEventHandler(calendarControl _DayRender);
}
protected void calendarControl_DayRender(object sender, DayRenderEventArgs e)
{
if(e.Day.IsOtherMonth)
e.Day.IsSelectable = false;
else
e.Day.IsSelectable = true;
}
Any Ideas why this does not work?
