How do you go about creating a complex servercontrol frontend?...I can't imagine you do Controls.Add() in the .cs files to add in divs, classes etc Can you embedd an ascx to make it easier to style?

I'm working on a Navigation Menu. I've created below ServerControl and it works, but I want to allow users adding some standard ASP.NET controls within my ServerControl Tags like label, image and so on.
<MdsMenu:ServerControlMenu ID="ServerControlMenu1" runat="server">
<MdsMenu:animation AnimationSpeed="Normal" AnimationType="Opacity_Height" Delay="1000" DropShadow="true" />
<!-- HERE HAS TO HAVE SOME STANDARD ASP.NET CONTROLS -->
<!-- e.g <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> -->
</MdsMenu:MenuItem>
</MdsMenu:ServerControlMenu>
My problem is here that how I can get Child Controls within <MdsMenu:MenuItem> and show them like as they are in the output. P.S: I overwrite RenderContents method
protected override void RenderContents(HtmlTextWriter output)
{
output.Write(OutPutStringBuilder.ToString());
}
I've written a ServerControl that contains a significant amount of javascript, and I'm using IScriptControl to pass parameters from the server code to the javascript. The javascript file is configured as an embedded resource, and a script reference to the file is being injected into the html by IScriptControl.GetScriptReferences(). The ServerControl is contained in a DLL assembly. When I use the control in a test page everything works fine.
What I want to do is to extend the control - to derive a new control from it, in a second assembly, that provides some extended functionality. (The first assembly contains code that is shared across customers, the second code that is shared across several projects for the same customer). So, my problem: I create a new ServerControl that derives from the first, but doesn't yet provide any new functionality.
[Code]....
Then I change my "<%@ Register ... %>" tag in the test page to reference the derived control. Things compile just fine, and the code-behind runs fine, but I get an undefined variable error in javascript. Sys.Application.add_init() is calling $create(), passing the <namespace>.<classname> of the javascript class, and it's throwing an error on the namespace.
Now, the namespace is registered on the first line of javascript file. Which makes it look like the javascript file might not be being included, when using the derived control. So I stuck a "debugging" line in front of the Type.registerNamespace(). Using the base control, the debugger breaks as it should. Using the derived control, it does not.
So, I look at the script includes in both versions of the page. They are identical. The sources are src="/testing/WebResource.axd?<random junk>", or src="/testing/ScriptResource.axd?<random junk", so I'm not sure which one refers to my embedded javascript file, but whichever one it is, the includes are identical between the page using the base control that works and the page using the derived control that does not.

I got a master page with a server control in it. Randomly the server control is inaccessible from codebehind. This doesn't happen on a specific action (eg a Button click or so). Currently I have no clue what this could be. I don't think it's output caching since this is not explcitly activated and the error happens far to seldom for that. But I'm going to disable caching in the master page explicitly with next deployment.
The control is defined in markup. The accompaning codebehind is:
PGFMainNavi.HasAccessToFunction = HasAccessToNaviItem;
// HasAccessToNavi is a local function
Exception is:
System.NullReferenceException: Object reference not set to an instance of an object

I have a gridview that contains check box in first column for each row. I also have a check box outside the grid view called >>>>
<asp:CheckBox ID="chkSelectAll" runat="server" Text="Select All" AutoPostBack="true"
OnCheckedChanged="chkSelectAll_CheckedChanged" />
I either can select more than one checkboxes from gridview then click on a button to get the number of checkboxes selected OR I click on SelectAll checkbox ( which is outside the gridview ) which check all the checkboxes in the gridview and give me the number of checkedboxes. When I select inidividual checkboxes inside the gridview, th e count of number of checkboxes is correct ( displayed in a lable ) However;
When I click "SelectAll" check box, it give me total of all checkboxes chekced in the
gridview + 1 ( extra ) I am trying to get rid of this extra one by checking if this "Allcheckbox" is selected to so I subtract one from the total count .. like this
// java code ... code not shown does capture the total count into c variable
varAllChecked = document.getElementById('chkSelectAll');
if (varAllChecked.checked== true)
litCount.innerText = c - 1;
else
litCount.innerText = c;
How can I create a form that creates or updates a complex type that takes a form like:[Code]....
I would like to either create two forms one for tblstudent and one for tbldata and tblStudata or create one form for all three and give the illusion of multiple pages. I came across an old Railscast that talks about virtual attributes and a helper called fields_for which helps you switch between model contexts in a single form. Is there a way of achieving this kind of functionality with C# MVC 2 or 3?
If this sort of thing is not possible how else might I be able to handle create/update scenarios without defining two actions amd voews for each table entity I need to work with or god forbid separate controllers?
I have a form which I use to create an issue. WHen you post the form, the form elements are that of a custom DTO. The DTO is then used on my POST method to create the new entity. That all works fine.
However, I want to add the functionality to add multiple issues at the same time from the same view. In effect, the user would click something like 'Report Additional Problem', and an extra set of form fields would appear (I will like use jquery for this, which I don't have an issue with). However, even with just leaving one set of form fields, the user should still be able to create just one issue. But if I habve my post method take a list or array of my DTO, it doesn't work.
Here is the post method before editing:
[Code]....
What I want to do is for this to take an array or list of NewIssueDto. I would then loop through each one in the list and create a new issue from it.

I understand the basics of setting up routes, I am trying to get a handle on how to organize more complex routes. Does the Route name do anything? I havn't seen a place it's actually used. If I have the route: controller/action/id/paramA/paramB/paramC. ParamA-C could be defining multiple parameters so First/Last/Zip or Phone/Zip/Birthday. Is it common practice to name the additional parameters with a generic name like paramA vs trying to differentiate a separate route for each?
Lastly, if you have multiple sites/functional areas in 1 site, lets say the asp.net site, each area MVC, Ajax, Forums ect were all different functional areas. Is it best to create a different group of routes such as hard coding the controller like:
MVC/action/id
Ajax/action/id
Forums/action/id
or is there a better way? What I am running into is 1 piece of the site overriding the other route because of the number/type of parameters.
I need to implement a wizardy, dynamic UI that uses complex validation of the style:
If A = 1, show controls B, C, D. B is required, C is not, and D is not required must be less than 30 if it is populated.
If A = 2, show controls B, D, E. B is not required, D is required but has no limits, and E is not required.
If B is not null, show controls B, D, E. B is not required, D is required but has no limits, and E is not required.
Historically, I have made my presentation layer as "dumb" as possible in that it is only responsible for capturing user input and binding it to the appropriate domain model. The domain model, in turn, contains the logic needed to validate it's state and that of any child objects, and then communicates any invalid state to the presentation layer via notifications. As such, this requirement for a highly "intelligent" UI represents a departure for me.
I think I have no choice but to construct 2 very similar class hierarchies:
one that will capture presentation business rules (i.e. what fields are visible) and control what renders in the View
one that will capture domain business rules (when field A = X, then field B should be not null and in the range of n to m) to disallow objects with an invalid state from being persisted
Sill I have far more questions than answers on my strategy moving forward. Is there a set of design patterns I can draw on to build such a dynamic UI? I do have the option of using ASP.NET MVC or WebForms, so whichever approach will produce cleaner, testable code is preferred.
I need to estimate (and probably build later on) complex filter in ASP.NET WebForms application. The filter has to be mostly based on ASP.NET AJAX or jQuery for high interactivity. The filter has to allow filtering data with complex logical conditions (and, or, braces) and several operators. A user has to be able to save the filter's query and use it (load it) later on (server logic). Moreover there is still discussion about in operator.
Application should provide some graphical filter builder. I want to have full control on set of operands (filtering fields) and operators. The component will be used for all filtering actions in application. My problem is only how to do the UI part - translation of builded "query structure" is not a problem.
Have you ever did something like that? Can you share some experience how to best and fastest build such component? Do I need to develop component or is there any existing one which has at least some of the functionality and can be extended to provide other functionality? Because I'm not very experienced with client side development, I don't know how complex task is developing such component from scratch.
Another possiblity is to define some meta query language and allow users to write the query to some query text box with support for building logical expressions. I have already checked available controls in DevExpress and Telerik toolkits:
DevExpress:
Pros: Really nice visualization, fast. We probably have DevExpress licences. Cons: Tightly coupled with DevExpress grid. Based on documentation no extensibility and no control over operands and operators. It uses operands provided as columns for grid - I need much more. Probably not possible to save and load filters.
Telerik:
Pros: Not coupled with grid, it looks like separate control. Cons: I didn't find documentation - I'm not sure about extensibility but the code looks like it uses some databind control as source of operands = problem. I don't like the visualization. Demo is really slow. We don't have Telerik licences.
I really don't know if this Post fit in this Forum section. But here I go. I need some sugestion to develop an ASP.NET code that generate complex IDs / Keys automatically. Let me be more understandable:
I want to create uniquelly IDs with more complex composition (kind of 18958351512783997769711... or crlu0xakecjzlgmjsgnedr55) or something link that (doesn't matter the lenght... those are only examples).
So, I can use that to set COOKIE ID's... PRODUCTS CODE ID's.... CUSTOMER's CART ID's... etc... But it need to generate uniquelly numbers. I don't know if you got my point I hope you did.
I'm currently implementing a project using asp.net, c# and the MVP (Model-View-Presenter) pattern. The main purpose of this solution is to deliver a graph to the consumer, to be used by a variety of systems. It is basically a custom graph server.
The view page in this particular case has an MSChart control on it, which has to be dynamically populated and configured based on parameters in the QueryString. This can be as diverse as totally different types of data sets, display modes and so on, using a lot of the properties of the chart control.
Many of these properties are again of types which are particular to the chart control and would require the same dependencies as the chart control itself if they are to be set by the presenter.
I'm trying to figure out the best way to expose the properties to the presenter so it can work its magic.
Should I:
Just expose the whole chart object and live with a system.web type dependency in the presenter project? Make accessor and translation properties for all of the chart control properties so that I don't have the dependency, but add lots of complexity? Other, that I haven't thought of?
To me it seems that it would be against the MVP pattern to bubble a display control up into the presenter, but it seems that trying to map all the properties to DTOs or similar would be a lot of work that would add a lot of complexity, and while the solution would be somewhat more loosely coupled, I'm not sure the gain would be worth it in this case. How would you implement something like this, given MVP?

View 5 Repliesi would like to ask what is the best way to position and align images on an HTML web page.
I will have approximately 10 user-controls that each have a set of images on them laid out in a specific pattern, eg - an arc, a circle, straight line, some other sort of curve.
How i can achieve this using best practices?
Update: All the images will be the same size.
Can i consume .NET web service and use it complex types in PHP?
Example:

Can i consume this method and use DataSet class methods in PHP?
Are there advantages in creating complex types in EF4 Entities and then use the complex properties in the repositories; instead of creating the aggregates in the the repository themselves? I.e. If the customer repository consists of properties of 3 entities: customers, addresses, email would it make sense to create a complex type consisting of the address and email properties, and add them as a complex property of the customer entity then just call the customer entity and the complex property in the repository, rather than just creating the repository class and aggregate the entities in the repository.What are there advantages or disadvantages in doing this in a MVC3 application?
