Creating Dynamic DataList Controls With ID's Based On Bound Data - Finding Alternative

Jun 28, 2010

As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.

I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.

I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.

Can anyone provide me with any alternatives here?

I created a database with ID, Title, Content, Date, ImgLnks, Image and Imagecaption and i'm using ObjectDataSource to populate the data. The field "ImgLnks" displays a new blank window with URL.

My question is, is there a way that I can put an Alternative Standard Text in this column instead of displaying the clickable link like [URL] etc.? Text like, "Visit Page".

Forms Data Controls :: Datalist Control Bound To List Of Objects?

Mar 17, 2010

How can I bind a datalist control with a list of objects. I have a list of objects that contain a name, desc, and url for menu commands that I am trying to show in a DataList. I am getting the list from a WCF service so I have a list called something like menuList which consists of a List<MenuCommands>. I then do a menuDataList.DataSource = menuList and then a menuList.DataBind but nothing is happening. What am I missing here? I need to use a DataList because I need the commands to be selectable.

Forms Data Controls :: Bound Datagridview Loses Count After Code Based Deletion

Feb 19, 2010

I have a bound datagridview with the associated tableadapter, dataset and bindingsource. A different component in our application can add or delete rows displayed by the datagridview. When this happens, the underlying database edits are correct. The problem is that the datagridview seems to lose track of the data.

Currently, when we receive the event that our data has changed we do the following.


If our example had something like 5 items displayed in the grid and a row was deleted, the grid refreshes with 3 items shown. If we manually refresh our grid through a button calling the exact same code, it displays the correct results. Is this an asynchronous call? Should we be refreshing the grid in a different area?

Finding Alternative To DataPager

Jan 24, 2010

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"
<asp:NextPreviousPagerField ButtonType="Link"
PreviousPageText="<< Previous" NextPageText="Next >>"/>

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:-



When i click on next image i need it to change to something like:-



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.

Archive File Search - Finding Alternative

Sep 2, 2010

I am developing a new project to list files and directories under an specified location on disk. I use normal methods like Directory.GetFiles() to achieve this task but the amount of files is getting very big (> 300000) and the site is becoming terrible slow.

I worked with Index server with previous versions of Asp.Net but I was wondering if there is a new way for my website running Asp.Net 4.0.

Also I heard something about Index Server is obsolete to achive file listings and search. Is there any new alternative?

C# - Finding Session Alternative In Global Scope?

Feb 24, 2011

Quick question: Is there a "per-user" data storage object (similar to Session) that I can store data in the global scope (similar to HttpRuntime.Cache)? Almost as if Session and HttpRuntime.Cache had a baby.

Full Background: I have a ASP.NET website that was originally written for a single thread. Now I changed it so that certain actions will spawn a background thread and the browser polls a service to get status updates.

The problem I am having with this is that certain pieces of data are stored into the HttpContext.Session[] object (membership authentication token, for example). These pieces of data need to be unique to each user and accessible to the background thread. Session is not available to the background thread.

I am aware of HttpRuntime.Cache but that would require micromanagement to segment out the users and to expire it at the same time the session is expired. Session, on the other hand, automatically expires this things at the right times that I want it too and is already used by things like the SqlMembershipProvider.

My question is, is there something that behaves similar to the Session but exists in the global scope?
