I'm using Dynamic Data and LINQ to SQL for some admin pages on a .NET 3.5 web app. All my admin tables have a CreatedBy, CreatedDate, UpdatedBy, and UpdatedDate.I'm looking for a way to inject the setting of these properties before the objects are inserted and updated.
I've seen an object_inserting hook if you have a linq to sql datasource in the web form, but I'm using dynamic data...is there an easy way to generically set that? And I've also looked at modifying each of the partial classes for my admin objects, but the closest hook I see is to implement the OnValidate method with the Insert action.
I've used the AJAX Slideshow Extender to create a very bare bones slideshow on the default page of my website. I have created a page function that returns an array of AjaxControlToolkit.Slide. When I manually create the array of slides, the slideshow works. However, when I use a LINQ query to build the array, the Slideshow doesn't display slides. I don't know what could be going wrong here, as there are no errors listed by Visual Studio, and the page itself loads without any reported error. Here is my code-behind. (From Devault.aspx.vb:

I understand I need to load my dynmaic control on every postback and preferrably in Page_Init(). But my dyanmic controls are loaded from a dropdownlist selectedindexchanged event handler. Now after any postback, my dynamic controls are gone. How would I force it to load on every postback ?
View 2 RepliesI need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

I really have a big problem(stuck) with two dropdownlists inside a detailsview.I have 4 detailsview : DdlRt,DdlRt2,ddlMobv1,ddlMobv2. Basically what happens here is that DdlRt2 gets populated when DdlRt is selected and ddlMobv2 gets populated when a specific value from ddlMobv1 is selected.
In code posted above the detailsview has a "Update" command and the problem is when the update command is executed the data is successfully posted to the db BUT! THE VALUES from DdlRt2 and ddlMobv2 dissapear! And I can't insert any more Items. The only Item that stays in these two dropdownlists is the default "Select Department" item which is't set in codebehind but is set in .aspx.....I can't figure what I'm doing wrong here It must be something with databinding & events.
So my question is "Why can't I insert any more items to these two dropdownlists after the "Update" command on the DetailsView is set or how can I preserve the values that are already in"?
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataSourceID="odsRegister"

I've used Enviroment.Newline() to do some html conversion stuff, but I've never ran into this specific problem.
Edit: Nevermind, it was working just fine, but I was replacing " " incorrectly. Stupid mistake. I have to convert the " " to <p> tags. I've done this before, but if anybody wants to answer, I'll mark their answer as correct.
I have an ASP.NET application with 5 .ashx HTTPHandlers that implement RequiresSessionState or IReadOnlySessionState.Upon calling the first handler I create a variable and store it in the session.When I call the next HttpHandler the variable is not available in the session object.I am use context.Session.I have a global.asax where I retrieve the sessionId.Is there a way to preserve session variables across HttpHandlers or does each Handler get its own session?
View 1 RepliesI have the need to add a javascript include to my ASP.NET page. The url of the javascript file has two key/value pairs in the query string. But the ampersand is being escaped and I don't want that.
Page.ClientScript.RegisterClientScriptInclude("myKey",
"https://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&s=1")
This results in the following HTML:
<script
src="https://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&s=1"

But what I really want is:

I am trying to figure out how to preserve the values of the controls on this page (just the user-submitted commission value and the sales region (eastern is 10% and western is 20%)).

Dim dblSale As Double
Dim strRegion As String

I have a form, mostly consisting DDL's. I constructed this form using a Master page with about 10 different pages attached. Each page consists of roughly 10 to 20 DDL's. My goal now is to navigate from one page to the next and back with out loosing the selected values in each of my DDL's on each page. I have thought about assigning each to a Session but that would really bog things down considering the amount of Data i would be storing. I would love to go the easiest route but my mission here is most efficient.

I've written a user control that has a button that a user can click to display an additional DIV. I discovered that it would be nice to make the control remember whether or not the DIV is visible after postback so that when the page reloads, the DIV stays visible if the user wants it that way.

I'm working with the 10.2 version of the DevExpress MVC controls. I have a page hosting a MVCxGridView and I need to preserve the current page when navigating away and back to this particular page.
I can see from the old ASPxGridView documentation that there's a PageIndex property, but this seems to only be accessible from a WebForms/Code Behind/Server Control type context. I'm using MVC and can't figure out how to preserve this page setting.
I've tried the cookie settings with the control but those don't seem to persist for me.
