.net Usercontrol Vs Customcontrol Vs Stringbuilder?

Dec 22, 2010

I'm building a product catalog which displays between 50/100 products per page.Since I want to have different browse sections on my site I've put each product into a UserControl. Well, not the products themselves ofcourse, but some labels, divs and images. I then set its properties in run-time when processing the database results. So the advantage is that I only have to change the product control at 1 place for the whole site. I'm putting the controls in a page using LoadControl in a loop.

However the pages are not loading quite as fast as other pages which process the same db query and output the same html using a StringBuilder. And since I want my site to perform well if/when it receives some decent traffic I'm worried about this. I haven't done any benchmarkings yet but I clearly see the difference. My questions to you is 'Are there any alternatives which are faster then using LoadControl with a customcontrol but are easily maintained (or atleast in 1 location)?'I was thinking of:

Creating a customcontrol (although I've never done it and don't know 100% if this will speed things up)Continue with the StringBuilder method and put the CreateProduct in my base class

[edit]Code[/edit]

I don't have the excact usercontrol code here but I will edit this post when I get home..but here is the simplified idea:

1) Getting my database result (using Subsonic 2.2 as my DAL)

DAL.ProductCollection coll = new DAL.ProductCollection();
if(coll.count > 0)
{
foreach(DAL.Product item in coll)[code]....

My usercontrol itselves just consists of 3 Literal controls and 1 Image control.

Custom Server Controls :: Passing Querystring To A Usercontrol?

Feb 26, 2010

I have a particular scenario and I would like to know how I can implement it in the most efficient way. I also have some queries related to this. The application is a AJAX 1.0-Enabled ASP.NET 2.0 Web application.

I have a link, which when clicked I need to show a pop-up div. The contents of the div will be displayed using a usercontrol. The usercontrol will display the contents based on a query string value.

I would like to know:

1. How can I implement this in the most effecient way. I don't want to use a separate page on which I will have the usercontrol and then display the page in the div.

2. Suppose I call a JS function ShowDiv() on the click of the link, to display the pop-up div. Say, I call the function this way ShowDiv('querystring'). Now how will I pass the value 'querystring' to my usercontrol.

Custom Server Controls :: Handling Events In Dynamic Usercontrol?

May 27, 2010

I created a customDropdown usercontrol with Events and It worked fine.

Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.

To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?

For Example

FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").

But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.

Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?

How to accomplish that and also how to handle the events for these type of situation?

Custom Server Controls :: Can't Pass Data From Usercontrol To Page

Jan 25, 2011

I tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.

Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)

Custom Server Controls :: Declaratively Adding ListItem(s) To DropDownList In A UserControl?

May 13, 2010

[VS 2010 RC1, .NET 4.0, VB.NET]

I'm working with a simple UserControl someone at my company created. It's basically just a DropDownList with a RequiredFieldValidator and some added properties (such as "Required", which controls the CSS styling of the DropDownList and whether the RequiredFieldValidator is Enabled or not).

Here is an example of the UserControl usage where a SqlDataSource is used to populate the ListItemCollection. I'm trying to specify an intial ListItem below (and would like the ability to add multilple ListItems if necessary) but can't seem to get this to work...

[Code]....

My code-behind looks as follows:

[Code]....

I've found several posts related to this but cannot seem to get the declarative ListItem to be added to the DropDownList.

I understand that using a WebControl is another option, but I'd like to learn how to get this method to work if possible.

Custom Server Controls :: Creating .NET UserControl With Collection-type Property?

Feb 21, 2011

How can I create a UserControl with a collection-type property which has a collection editor?

I've a CompositeControl with an ArrayList-type property which has CollectionEditor-type designer. You can see this property on Properties window with a "..." button which launches a collection editor. This works fine and all but I want to apply the same to a UserControl and I've couldn't manage to pull it off so far. I've done the same thing what I've done with my CompositeControl but the property either doesn't even show on Properties window of the UserControl or shows as a single value property with no "..." editor button.

This is what I've done with CompositeControl:

Forms Data Controls :: Use UserControl Inside An EditTemplate Of A ListVIew?

Oct 5, 2010

I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.

A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing

A UserControl in EditTemplate.

Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)

Custom Server Controls :: How To Get The Value Of Readonly Properties Of Server Controls Inside A Custom Server Control

Apr 4, 2010

I have a custom server control inheriting from CompositeControl. It consists of two RadioButtonlist controls that are rendered side by side in an html table. The number of ListItems in each RadioButtonList is not known until runtime. Depending on how many items each list contains, the RepeatColumns property of each list is set differently. To do this in the handler for the ItemDataBound event I need to get the count of ListItems in each RadioButtonList. How do I expose the Items.Count property of each internal RadioButtonList as a top-level property? I tried using a getter to return the count but this generates a compile-time error to the effect that the count cannot be assigned to--even though I have not created a setter.

Similarly, in the handler for the Submit event, I need to get the ClientID of each internal RadioButtonList to pass to a method that checks for data changes. How do I expose the ClientID of each component RadioButtonList as a top-level property?

I can of course index the Controls collection of the composite control to access the child control and read its properties--but that defeats the whole point of making a complex, independent custom server control.

Custom Server Controls :: Custom Composite Control With Custom Templated Child Controls?

Mar 22, 2011

I am trying to build a custom composite control, which allows me to add custom content to each child control. It's a similar concept to what you have with a GridView and TemplateColumn. The markup used to place the control on the page would end up being something like this:

[Code]....

I have the code below, which allows me to put that markup on the page without throwing any errors, and it renders all the correct HTML, except it doesn't render the contents of the ColumnTemplate. I have replaced the Render() code with a comment because it's quite long winded and doesn't add anything important here:

[Code]....

I have tried to follow examples on MSDN and other forums but I can't make this work. I think I'm missing the code to render the contents of the template, but I don't know how to hook that up.
