I want to add a class to a div inside my repeater control based on whether the query string value is true or false, so that I can style it differently.
View 6 RepliesI have a repeater control:
<asp:Repeater ID="rep" DataSourceID="XMLDSCompare" runat="server">
<ItemTemplate>
<h4><%# XPath("title")%></h4>
</ItemTemplate>
</asp:Repeater>
Now if its the first item in the total resultset, I want to add <div> to ItemTemplate control, if its the 2nd item, I want to add </div>
So output would be (not including table tags generated by repeater control):
<div>
title 1
title 2
</div>
<div>
title 3
title 4
</div>
<div>
title 5
title 6
</div>

Question basically crams it all in... I'm loading a page with a querystring (ID), and I need to use that ID to set the selected item of a ListView when the page loads. The ID is a DataKey on the ListView. I have no code of value to post--none of my attempts at this work.
View 2 RepliesI've added a div overlay to my repeater control using absolute positioning. Predicably, this simply renders all of the divs in the same place. Is there any way that I can put this overlay over each row of my repeater?

How do I insert the value of ListID into the query string?
I need to know how can I select a gridview row based on a query string data. In my case, the query string will contain the id that exist in the Table related to that grid. Is there a way to do this from the code behind? In other words, if I click a link with that specific query string, can I open the page and tell my grid to select a specific row based on the table row id?

I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.
My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processedafter the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.
Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.
I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions. I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater.
I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there would be a big problem with memory.
I am trying to use a repeater control that will display a hyperlink control. For the text of that Hyperlink control I would like to concatenate to fields from my data source (lets say First Name and Last Name). How would I do this appropriately for the Hyperlink control within an ItemTemplate?

View 2 RepliesI have a web page that has a repeater bound to a data source. I beed to change a label inside the repeater based on the data that is in each repeater item. For instance, for the first item it might be one thing, and for the next item the label may be something else. I am currently doing some processing in the prerender event, but I don't know if I can or how to access the data source fields there. Where and how do I get access to the data in each item so I can change the label text?
View 3 RepliesI have a hyperlink column. I need to add just one query string to the url. It needs to pass the string located in the first column of the same row. Let me know if you need more info. Edit: Also, if you don't mind it might be useful if I was able to pass the primary key of the object bound to that row, instead of the string in the first column. Would that be tricky to do? Either would work fine.

Summary: I need to authorize pages based upon the data present in the query string of a url, not just the page name.
Background:
Let's say I'm building a library inventory system. Users can be created and assigned to a single library in either an Admin or User role. There are hundreds of competing libraries in the same database, so it's important to ensure that users of one library cannot view inventory from another library.
Right now I'm using a pretty standard ASP.NET setup: Forms Authentication using the SqlMembershipProvider. Authorization using the SqlRoleProvider, configured via <authorization> sections in the web.config. Security trimming with the SiteMap provider to hide unauthorized pages.
To control the inventory information from leaking, I'm manually checking a user's associate library ID with every inventory query. It works, but it's tedious and prone to errors. There has to be a better way.
Question:
Now users have the ability to create arbitrary "collections" within a library. (e.g. Collection A has Books 1, 2, & 3 in it.) Admins want the ability to grant Admin / User access on individual collections, not just the entire library.
So, if a user goes to www.com/Book.aspx?BookId=1, the system needs to ensure that user has permissions for the collection that "Book 1" is in before showing the page. If they go to www.com/Reviews.aspx?ReviewId=23, I need to make sure the Review is for a book that is in a collection that they have permission to view.
1) How can I implement this in the most standard ASP.NET way possible?
Manual checking within a base page?
A custom HttpModule?
A custom Role Provider?
I'm not interested in how to store the admin/user permissions, but rather how/where to authorize based on those permissions.
(examples on how to implement any of those are appreciated)
2) To further complicate it, I'd still like security trimming to check if the user has Admin rights on any collection or library and hide the admin pages if he doesn't.
Is there some way that qury string variables can be added dynamically ? Suppose Page one.aspx?Id=3 redirect me to Two.aspx
Can I add some parameters in Two.aspx before page loads ? I know query string collection is read only and it looks not possible but just asking there may be some way to do this.
On the left hand side I have a tree navigation . It is populated from a XML file with . What I want to achive is when a querystring of the value of the XML file is matched , the tree node sets a setfocus or highlights on a particular node from the querystring passed through. I cant find a method which mimmicks findtreenode with value x and sets a selected .
e.g treenode is filled
home
|
folder 1
| -- item 1
| -- item 2
|
folder 2
| -- item 3
| -- item 4
when a querystring of SC=Item 1 is passed , it should search against the tree and open the folder branch and select item Item 1
I can use a for next loop and loop through each node but it will get slower as more nodes are added.
I am using IIS 7 and have URL rewrite turned on for a friendly URL.
The problem is that in side that pages repeater (right under the captcha) when I click on the images in there the page redirects to /null/ which then throws a 404 error. I have turned off url rewrite and removed all rules and that didnt solve the problem so I dont think its related to that.
I have also noticed that in my master page if I use <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
then the client side ajax fails to load, sys becomes undefined and that may be the problem here
I'm at a loss, this is the first time I have seen these problems occur.

Now there are five items in the ItemTemplate of this repeater..what i want is to set class of each of the anchor tags as "mySprite id1,mySprite id2 , mySprite id3 and so on.."
for that I did this in code behind...
for (int i = 1; i < 6; i++)
{
Name.Attributes.Add("class", "sprite id" + i);
}
Now when I view page source, ALL my anchor tags have got class set as class="sprite id5"
I have this code which takes a value from a dropdown control as a parameter.

I'm now changing to a list control so that multiple items can be selected. So far I have some code that places the items selected into a string that looks like this:
'item1','item2','item4'
For the above example I would need all the the records returned when the field action_ref contains either item1 or item2 or item3.
I've a page in ASP.NET, whose appearance can change based upon a given parameter(say query string),
How can I achieve this in ASP.NET, Master pages concept won't work here, as even the contents of the page and positioning of the controls on the page can change based upon the parameter.
One solution I can think of is using XSLT, but is there any other solution I can use to solve this problem? Is there any concept of templates I can use here?
I've got a repeater bound to a datasource through the code behind. Everything is working fine so far except for this, I'm trying to concactenate a bound field as the id on a query string to an image handler:

What am I doing wrong?

And for the life of me I dont recall how to do an inline if when inside this repeater.
