Dynamically Generated Checkbox Datalist

Your site should remember if a user is logged in, via the session. Every page should be derived from a base page that redirects to the login page if the user is not logged in.

I have been given the "opportunity" to expand my ASP.net coding skills but I have hit a dead end at the moment. What I need to do is create a form that is generated by two SQL server tables. Table one holds general categories and table two holds items under those categories. Both tables are linked by a common key column. I have successfully generated a form from a two table dataset linked using a relationship. The form places each category and associated items with checkboxes in an HTML table cell. I need to know if I can dynamically bind boolean column data to the checkboxes by somehow inserting the generated table in an editTemplate of the datalist. I think maybe I've gone about this backwards but I'll appreciate any help to get me moving again.

I hope the question is clear enough, thanks for any help.

I recommend reading the article I link to in my sig, as it's clear you don't know how to use google.

If you have a link, putting target="_blank" in the attributes will cause it to open in a new window.

I am trying to open a password protected MS Access file on my website using the foloowing code

string cstr = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\uploadtest\WebSite1\data\Data.mdb;Database Password=testing";<br />
 OleDbConnection ocon2 = new OleDbConnection(cstr);<br />
 ocon2.Open();

This fails with a "Could not find installable ISAM." error.
Is there something I am missing, I have no alternative to using a password protected MS Access data file in this process.

Hello all,

As far as I have seen in google, this is a very commom problem, but I can't make it work.
I have a webservice that access a com dll. It used to work fine in another computer, but now, when I try to instaciate a class from this dll, I get this error:

Server was unable to process request. --> Access is denied.

I already have disabled the indexing service, added aspnet, iusr_machineName to the folder's permissions, but nothing seems to work.

Anybody has any ideas?

Thanks

Peterson

Disabling a ModalPopupExtender via JavaScript

Are you sure the Com dll is registered ? Perhaps that's the generic error you get when the dll won't start ?

Component Services (dcomcnfg) -> DCOM Config. Find your component and configure some permissions for it (same as you would for folders).

I have a ModalPopupExtender whose TargetControlID points to an <asp:HyperLink /> control:

<ajaxToolkit:ModalPopupExtender
ID="_popup"
TargetControlID="_hlLaunchPopup"
PopupControlID="_pnlPopup"
BackgroundCssClass="modalBackground"
CancelControlId="_btnClosingX"
DropShadow="false"
runat="server" />

<asp:HyperLink ID="_hlLaunchPopup" Text="Launch Popup w/ Checkbox" runat="server" NavigateUrl="~/Default.aspx">Launch Popup w/ Checkbox</asp:HyperLink>

On the popup, there is an image of an "X"; this is the CancelControlId.

There is also a "Don't show me this popup again" checkbox, which writes a cookie to the user's machine when checked.

What I want to happen during the OnCancelScript (fired when the user clicks the "X", of course) of the ModalPopupExtender is this:

If the user has checked the "Don't show me again" checkbox, then the ModalPopupExtender will be "detached" from the hyperlink so that if/when the user clicks on it again, the user is NOT shown the popup and they are directed straight to Default.aspx.

I looked through the source code, and it doesn't look like there is a "disabled" property on the MPE. It looks like the only solution involves removing event handlers from the button, but I'm not exactly clear on how to do that. I suppose I could also hook into the showing event and do a JavaScript redirect, but I would rather not do that; seems like a kludge.

Any tips?

Thank you!

As far as I'm aware, there isn't a way to truly disable the popup, other then using the $clearHandlers[^] method on the button itself. The downside to this is that you'd have to do it on any postback operation (including an async postback run through an UpdatePanel). Detaching the event also suffers from a bit of tricky timing in a postback scenario, as you're in a race with the modal extender trying to attach the event.

The ModalPopupExtender does have a client-side API which exposes a showing event that can be trapped, and cancelled. This will allow you to stop the popup from showing itself, although, the event will still be triggered on each click of the button. For example, the following was my quick prototype:

<ajax:modalpopupextender id="MyExtender" behaviorid="MyExtenderBehaviorId" targetcontrolid="PostBack" popupcontrolid="test2" runat="server" />

<script type="text/javascript">

  var loadInitialization = function()
  {
    var extender = $find('MyExtenderBehaviorId');
    var handler = Function.createDelegate(extender, function(sender, args) { args.set_cancel(true); });
    extender.add_showing(handler);
  }
  
  Sys.Application.add_load(loadInitialization);

</script>

My apologies for the poor formatting, but CopyTextAsHTML doesn't work for code-in-front.

Hope that helps. Smile | :)

I have been little out of touch with ASP.NET AJAX. But as far as I can recall,
You can always detach the behavior from the HyperLink control. You can do something like this:

var h = $find("ModalPopupExtenderID");
h.dispose();

where ModalPopupExtenderID is the client of of you extender. Alternatively you can use Sys.UI.Behavior.getBehaviorByType function to retrieve the behavior and then you can dispose it. Disposing it will automatically remove the behavior and free the event handlers.

You have, what I would term, a very formal turn of phrase not seen in these isles since the old King passed from this world to the next. martin_hughes on VDK

SqlDataSource Searching / Filtering

10-Apr-08 8:05

I hadn't thought of that. Its a great approach, and very clean. I like it.

I do want to point out that you'd need to run this code for every async postback performed by an UpdatePanel anywhere on the page. The client-side page manager will reinitialize all script components on the page each time an UpdatePanel refreshes. Obviously, this would also have to be repeated on every standard postback.

In your opinion, what is the best way to implement searching / filtering on an sqldatasource? Right now i have my datasource linked to a gridview. I use the FilterExpression property and assign is a "LIKE %" expression, and FilterParamerters which are control parameters.

I have a feeling that there is a better way to do this more efficiently, and securely (beware sql injections).

Any suggestions ?

ASP.NET membership tables in SQL Server

10-Apr-08 6:01

That's a rather broad question for a reasonable answer on a forum. I'd recommend that you start by getting Framework Design Guidelines[^], authored by Brad Abrams and Krzysztof Cwalina of Microsoft's CLR team. While you're waiting for that to arrive, start reading through some results from Google[^].

Hope that helps to get you started. Smile | :)

Hi guys,

I've just started a new ASP.NET application and this time we're using SQL Server 2005, I've normally uses MySQL with the .NET Connector (a membership and role provider for MySQL).

And when I'm looking at the tables generated by the membership provider there's one table I don't recognize: the dbo.aspnet_Paths table. It has three columns (ApplicationId, PathId, Path, and LoweredPath).

So, what is that normally used for?
I've tried to google for it and so forth, but without any luck.

"When you have made evil the means of survival, do not expect men to remain good. Do not expect them to stay moral and lose their lives for the purpose of becoming the fodder of the immoral. Do not expect them to produce, when production is punished and looting rewarded. Do not ask, `Who is destroying the world?' You are."
