I have very strange Cascading Dropdownlist behavior. When I use one parent, one child - everything is fine, but one parent two children combination does not work well. Sometimes both children show right data; sometime first is fine and second is grey, or first is fine and second [Method error 500], or second is fine and first is wrong and so on.
Did somebody try to use parent two children combination?
How do I stop the extender from providing shadows to a parent controls children?
I have a Panel (which the dropshadowextender is associated with), the panel contains a couple of labels. Currently the labels are shadowed.
Can someone point me in the right direction for adding a parent then sending the user to a new page to add children one by one?
My example: Exam (Parent) to ExamQuestion (Children).
I am new to xml, i want to looping through the below xml and save the records in the database. the below xml is parent child combination, parts as to be saved under respective parents. if the source field is M then there will be child item for that.
<PARENT>
<COMPONENT>
<part>test1</part><source>M</source><ParentPart>parent</ParentPart>

I have two tables in SQL. The first defines the parent, and has a primary key column called ParentId. I also have a child table that has a primary key, and a foreign key as 'ParentId'. So the two tables form a one parent - to many children relationship.
The question is what is the most efficient way to pull the parent + child data C# code? The data has to be read into the following objects:
[Code]....
and use LINQ to merge all parents with children. This approach makes 2 trips to the db.
The third and final (also most inefficient) approach is to grab all parents, and while constructing each parent object, make a trip to the DB to grab all its children. This approach takes n+1 connections: 1 for all parents and n number of trips to get all children for each parent.
Any advise on how to do this easier? Granted i can't get away from using stored procedures, and I can't use LINQ2SQL or EF. Would you prefer Data Tables vs DataReaders and if so how to use either with approach 1 or 2?
I have a parent/child relationship that I'm currently pulling via the EF .include() method and displaying via two foreach loops in my view -- the first foreach loop is for the parents and the second is nested inside each parent and is for the children of that parent.
This has worked fine, but now I need to display information about each child that is not contained in my main child table. The table that contains this extra information only has a relationship to the main child table and thus there is no association between this table and the main parent table --- i.e. the .include() method can't pick this up. I've looked, found nothing and thus assume that I can't have two .include methods chained together. (even if I could, would this be efficient?)
I know I can perform a simple join and pull all of the child information with the parent records, but that would create issues with my paging because I want the page size determined by the number of parent records displayed. For some parents, there are only two children; other parents may have 10 children. So a simple join would create records where the parent information is duplicated and would throw off the paging.
Ideally I'd like to pull the parent information and pull the children information and connect the two when the view is populated, but I don't have a clue on how to do this efficiently (if that's even possible).
I want to remove parent control (which is span in this case) without deleting its children controls from container. how can I accomplish this in asp.net c#?
you can see the code here: http://pastebin.com/9NiriWXN
Note: I can easily find the "newsright" control and return its parent (which is span in this case)
I have been having an issue when expanding a treeview, it looks fine when I load it, but when I click on a parent node it does expand, but also puts like 2 other parent nodes undernearth it. I am thinking it's because the treeview is saying that the parent nodes that have children have an index of 0, while everything else as there own index.
View 4 RepliesI have a basic CMS which I'm adding to a site to display some downloads organised into groups. I have two tables, one for the groups and one for the downloads. I'm using a repeated to display the groups with another repeater inside to display the children. This works perfectly.
However some of my download groups may not have any downloads related to them and I'd like to handle this by filter the groups so that only those with a relate download record(s) are shown.
I'm trying to do this with the query which populates the top repeater based on some ideas I read but I must be going wrong with the syntax.
Here is what I'm using to try and only select downloads groups which have downloads linked to them by the download group ID.

Can anyone offer any thoughts on how I should construct the query to perform this?

I can create web parts which allow me to manipulate fields on SharePoint forms.
But I have not found a way to be able to combine the two things.
I can't access the content of one web part from the other kind (WebApp Page Viewer & Jquery Content Editor Web Part being the two kinds).

I was wondering to use JQuery with the light wieghted Json and it was a wonderful experience and a very positive performance boosting or the entire project.
I was hoping that anyone else had the same experience with asp.net project geared up with Jquery and Json?
i am now think of how to get all the output for all the combination
eg.
given : 1234
output = 1234,1243,2143......and so on.....all 24 possible output
if given : 123
output = all 12 output
if given 12345 , all 120 output...
can someone provide me the algorithm or formula for that ?
I have spent time learning coding using master pages in inline styles and my sites are functional but look lousy. Now I am turning to learning CSS and to make my sites look more professional.
I wanted to try to convert my sites to using CSS. So I ask the question which is better option?
Also does anyone who develops in a corporation know if Master pages are use much?
I need to create an ASP.net page that has a control on the page that has a five-level TreeView on the left side of the page, and accounting balances on the right side the coincide with each breakdown in the tree. Top level is company, next is group, next is program, etc... and the balances break down accordingly.
I've seen that there are controls out there such as TreeView/ListView combination controls that can do this. Is there any tutorials or out there on how to go about accomplishing this without paying for controls? Could a treeview do this alone by spanning data across the entire length of the columns since every level will have totals on it?
I have such XMl
<root>
<list>
<list>
<topic></topic>
<topic></topic>
</list>
<topic></topic>
<topic></topic>
</list>
<topic></topic>
<topic></topic>
<topic></topic>
</root>
I need to get the first level of children:
<list></list>
<topic></topic>
<topic></topic>
<topic></topic>
I try to do like this
var list = x.Descendants().Where(e => e.Name == "list" || e.Name == "topic");
Currently im using EF and using its datacontext directly in all of my actions, but since i started reading about loose coupling and testability im thinking that thats not the best way to go. Im trying to understand all the pro's and con's before i start refactor all my current code.
Problem 1:
Considering that every entity needs its own repository, and thus has to setup its own connection to a datasource (lets assume a database using EF), wouldnt that give alot of overhead if i need data from 5 different entities on a single page?
Problem 2:
What im seeing aswell in all the examples which i found online is that most people (even people like shanselman) implement the repository pattern using the entity classes which are generated by either LINQ or EF, doesn't this defeat the purpose of repository pattern with regards to loose coupling? On the other hand, what is the alternative, using POCO classes in combination with for example AutoMapper? (this scares me a little) Im hoping that a few people can shed some light on this, because im a bit confused at the moment if the repository pattern is the right choice for a website.
Is anyone using this combination together? I ask because I have posted previous questions without reply. There seems to be a compatibility issue with the database in VS once opened up in R2 - any got any experience of this and how to work round it?

What i would like to accomplish is that a partiel view contains a form. This form is posted using JQuery $.post. After a successfull post javascript picks up the result and uses JQuery's html() method to fill a container with the result.
However now I don't want to return the Partial View, but a JSON object containing that partial view and some other object (Success -> bool in this case).
I tried it with the following code:
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Edit(int id, Item item)
{
if (ModelState.IsValid)
{
try
{
[Code].....
However I don't get the HTML in this JSON object and can't use html() to show the result. I tried using this method to render the partial as Html and send that. However this fails on the RenderControl(tw) method with a: The method or operation is not implemented.
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());
}
