Alternative To DataPager - QueryString
Jan 24, 2010
I am really fed up with a datapager I am using as I cant change the value of the querystring. I currently have this code:-
[Code]....
When I first arrive on the page I see this querystring, depending on the picture selected a different ID will be shown:- [URL]
See the bold. When I click on the next image I need the querystring to change to the ID of the image. So something like. But it does not work, I don't know to do it. I tried with adding QueryStringField="String" but this didn't work either.

I am using a datapager on a page where different images are shown. Now i am using the following code:-
PHP Code:
<asp:DataPager ID="DataPager1" runat="server"
PagedControlID="lvPhotoViewer" PageSize="1"
onprerender="DataPager1_PreRender">
<Fields>
<asp:NextPreviousPagerField ButtonType="Link"
PreviousPageText="<< Previous" NextPageText="Next >>"/>
</Fields>
</asp:DataPager>
Now this code does run through all the images, but i need to alter the querystring and make it change to match the ID of the photo displayed. I tried adding QueryStringField="String" but this was hopeless.
I have a querystring like so:-
Quote:
[URL]
When i click on next image i need it to change to something like:-
Quote:
[URL]
See the PhotoID has changed. But it currently does not do this. When i arrive on the page the PhotoID stays the same. I have been trying for a while and im starting to give up!
So was wondering if there was an alternative.

I am using a Datapager in my project with a ListView control. The Datapager is set to use a querystring value Page, so that a typical URL looks like: [URL]. The problem is that the ListView throws an ugly error if the pageview is invalid (0, for example).
The error is:
Specified argument was out of the range of valid values.
Parameter name: startRowIndex
The error originates in the ListView SetPageProperties method. What is the best way to address this? Can I override the SetPageProperties method in some way, to check the startRowIndex parameter? Here's a very simple page that replicates the error: [URL]. A copy of a simple webapplication project demonstrating the error: [URL]

I have a datapager control
<asp:DataPager ID="DataPager1" QueryStringField="pageid" runat="server">
The control works perfectly when the QueryStringField "PageID" not not encrypted. When it's encrypted the control no longer works. Is there a way to assign the page number in the back end? Is there a way to work with encrypted query string with this control?

The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid()
Dim id As Integer = Integer.Parse(Context.Request.QueryString("id"))
Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString
Using con As New SqlConnection(strConnString)
Using cmd As New SqlCommand()
cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"
[Code] ......
However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
<FooterTemplate>
<asp:Label ID="lblEmpty" Text="No Result" runat="server"
Visible='<%#boolean.parse(([b]list[/b].Items.Count=0).ToString())%>'>
</asp:Label>
</FooterTemplate>
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.

I'm intermittently seeing this exception being thrown:
A potentially dangerous Request.QueryString value detected
However when I look in the IIS logs I can see that the request that failed has no querystring logged against it.
How could this be? Are "dangerous" query strings being stripped from the log or something?

What's the next best alternative to IIS? What's the alternative if I install a server in Windows and what's the alternative if I install a server in Linux. I'm not allowed to install IIS here at work, since they've experience security issues here.

One of my classes currently is a C# class. I was given a small assignment for creating a bare-bones Facebook clone. I am now ready to list wall posts on user's pages.Having just been taught about DataLists (using tables), I thought I'd use one. However, I'm told "The messages list must be displayed without using table tags (<table>, .<td>, etc.)"
This is not really a coding question, just asking for a recommendation on how I should go about displaying posts without tables while still easy on the eyes (including name, the poster's picture, the message, and a date).

I'd like to add some properties to logged in user. The last time I did this was a website made in VS2005 and ProfileCommon worked just fine. It seems however that this class is not included in web applications in general and .NET 4.0 in particular. I there for assume there is now a better way of doing this. Could anyone tell me what it is? In short I'd like to add PersonID to user's login to make it easy to hide information not related to that particular user by setting controllers like
if (!User.IsInRole("Administrator") {
var item = PickLists.GetPerson(User.Profile.PersonID); // or something like it
return View();
}
var item = PickList.GetPeople();
return View();
}

I would like to convert my Frames-based web application to non-frames.Challenges:I have a frame of exploding tree menus (total tree around 1,000 menu choices - up to 5 levels of average 7 choices for each item). From this menu, one gets to the first content page (all dynamically created data pages). The content page can link to other content pages and so one.As the user navigates around in the right side, how can I have the display retain the exploded structure of the menu without using Frames (in a way that the browser back button will continue to work).Does anyone have an example of an application where there are many content sections on the screen which retain their state as the page is refreshed, without using frames?

I have a ListView that I am paging with a DataPager. I would like to set the initial page of the pager on Page_Load. I have tried the DataPager.SetPageProperties method but it's not doing what I need. Here's how I'm calling this method: dataPager.SetPageProperties(3, dataPager.TotalRowCount, false);
The line above trims the datasource to start at the third item and paging still starts at 1. This is not what I want. I want to keep the entire list of items and just jump to a specific page in the list. Is there another Property and/or method of a DataPager and/or ListView that I should use?

Is anyone able to offer any decent alternatives to the telerik ASP.Net controls.
I'm in the market for a decent grid control with all singing all dancing extensions... bt I'm finding the telerik grid really hard work to deal with.
The telerik controls do look good, but after a day of hard work with them I'm just looking to see if there are any other 3rd party offerings?

I have a datapager with next and previous buttons as so:
<asp:DataPager ID="dpFeaturedPager" PagedControlID="lvFeaturedTips" QueryStringField="ftpg" PageSize="1" runat="server">
<Fields>
<asp:nextpreviouspagerfield ButtonCssClass="featured-previous" PreviousPageText="Previous" ShowNextPageButton="false" />
<asp:nextpreviouspagerfield ButtonCssClass="featured-next" NextPageText="Next" ShowPreviousPageButton="false" />
</Fields>
</asp:DataPager>
When there is only one page available, the Next and Previous links are rendered as so: <a disabled="disabled">Previous</a> I have not seen this disabled tag before, and presume it's coming from the datapager control which I won't be able to control. As usual, this is fine on FireFox but on IE7 the Previous and Next text does not render correctly - it is outlined (what I would expect disabled to look like to be honest - but looks a bit ugly in the page!)

I am using ListView/DataPager.
For performance reasons I page my results at database, using ROW_NUMBER(SQl2005).
At my C# code just comes one page at time. How can I say to DataPager that I have more rows that really are at my List?

I've just taken my first stab at making a ListView, ObjectDataSource, and DataPager run in an AJAX panel.
I had trouble getting it to work until I removed the QueryStringField="page" attribute from the DataPager. This attribute causes the current page to be passed as a query argument in the URL. For obvious reasons, I guess that won't work when posting back using AJAX.
Now my question is if this hurts my SEO. When I used QueryStringField, the page links appeared as regular links with various query arguments. But now the links are just javascript. Haven't I hurt a search engine's ability to scan related pages?

I loved the features of using app_offline.htm on my ASP.NET WebForm based sites.
Upload the file and your app is immediately "offline". Snappy.
Now that I'm using MVC 2, I noticed that this no longer works.
Is there a way to get this behavior in ASP.NET MVC 2 like it did in WebForms?
