I write a C++/CLI program using a listbox. I google for half an hour to find a way to clear all the exist items in the listbox. I finally see a "Clear()" function from a C# forum. I test the function in my program and it worked.
I have visited msdn website. http://msdn.microsoft.com/en-us/library/system.windows.forms.listbox.items.aspx
I could not find any "clear" method in that page. I am lucky this time to use a C# forum hint to solve my C++ problem, but I want to know the right way to find the information that I need from MSDN.
THanks
It was there you just did not drill down deep enough. The Items property is a ListBox::OjectCollection Class. The collection class has the Clear Function. You can find out most of the information you need by searching the MSDN site and exploring all of the links on the page that pertain to the function you are looking for.

I'm looking for leads on how to implement a (search-)result browser without using paging. But more like how twitter/facebook do it.
At first only 10 or so results need to be displayed but when scrolling down, more results (if any) should be added asynchronously. I've found examples with a [more] button at the end but I would like the browser to automatically fetch more when the bottom of the pane is reached.
I'm having trouble finding the right examples. Probably because I don't know what keywords to google on...
Hope you can help me out in the right direction!
Kind regards,
Paul
I advise you read following article regarding this subject:
Infinite Scroll in ASP.NET MVC
There is also a sample application available here.
Refer to the Replace paging with jQuery and subsonic continuous scrolling method blog post.
Have a look at the following pages:

I believe that should help you!
I asked this question at jquery forum cf: my question, but was asked to come here and look for Oleg.
I've done a lot of research online and tested a bunch of code either mine or from the web, but so far have had no luck. I keep on reading that I need to use the oneditfunc function. As you see in my question at the jquery forum, I added those action buttons in gridComplete. Where do I declare and define the oneditfunc function?
The example at http://www.ok-soft-gmbh.com/jqGrid/ActionButtons.htm does look like what I am looking for, but I can't use the pre-defined 'actions' formatter, I have to use buttons which bear the texts Edit, Save and Cancel.
There is an example at http://www.trirand.com/blog/jqgrid/jqgrid.html# under Row Editing (new) > Custom Edit, which I followed to create mine you've seen in my original question at jquery forum. Unfortunately, those buttons don't toggle.
It just doesn't make sense to display the S(ave) and C(ancel) buttons when the rows are not even in edit mode. So I do want to fix this by toggling them. Any ideas to share? I am sure this is going to help a lot of people as no working examples can be found online. Thank you!
For those who are looking to solve this problem. I have solve it and I have posted my solution at http://forum.jquery.com/topic/jqgrid-inline-editing-buttons .
I'm having problems with something which seems like an easy task, and most probably a stupid question. It will probably be my all time low experience in programming but I would really appreciate any help!
I'm using Galleriffic to display my portfolio site, and I am looking for a way to directly link to an image+description not being the first in the gallery. I would like it to link from other webpages, or from plain text/pdf documents.
In short, I would like it to link to a webaddress of slide 5 with something like:
Slide 5
but doing it this way obviously doesn't work.
Although others have tried to explain:
https://stackoverflow.com/a/7910501/1074297
jquery cycle link from external page to specific slide?
I can not seem to accomplish it, and it does not help at all that I am not a programmer.
not sure if it is too late, have been search the solutions for whole day, final found out the example 4 in the official website actually make the #link show on the address....so you can actually link the specific image ('slide'') from external page...amazing!!!!!
check this out

You can find the script after all the or just before ... and place it to your template...it works well for me, hope it helps, good luck
Having no luck here trying to find a solution to this.
I've set up a looping selector based on this guide. (I also used the ListLoopingDataSource class in Part 2 in order to have strings in my looping list).
What I want to be able to do is then change another element (an image box/placeholder) on my layout, based on what is currently selected in the looping selector.
No real idea how to do this, the onSelectionChanged event is kind of abstracted and not really useful? I'm not sure how to programmatically change images either, it doesn't look like I can access a resource from the code base, only from the xaml.
Any help/suggestions would be greatly appreciated.
I found that I could do this by using binding.
I have a TabContainer inside a data bound FormView (to present the information by category ex: Client Bio data, health history, financial details...). The Update and Insert of the formView doesn't work (posting NULL values to the database) - I guess the FormView cannot find the TextBoxes inside the tab container's tab panels.
Some of the forums say that it's because of the TabContainer's implementation (by design) of "INamingContainer", and a hack is to take control of the TabContainer's
source code (ajax ctl toolkit's source code) and remove the "INamingContainer" interface from it... Too complicated to my taste .. I'm kinda lost.
Well is there a straight forward and better way to fix this? I'm dazzled to see that the toolkit has failed to implement this basic functionnality as for most developper ordering info (tab control) with formview is a common need.
Thanks in advance,
Jeewai
Answering my own thread... I got some great inside from the asp.net forum and decided to post the solution here: Reproducing the explanation that helped me out:
Hope that will clear out some questions to other users who may encounter the same issue.
Best,

Hi JY,
The short answer is that when a Bind statement is compiled, there are some limitations on extracting values for an insert/update. If the controls within the FormView are then within another Naming Container (TabContainer and TabPanel are both naming containers), then the compiler can't resolve how to extract the value from the TextBox. I have a more detailed discussion of this on my blog at http://www.aarongoldenthal.com/post/2009/03/15/ASPNET-Databinding-Bind()-Method-Dissected.aspx.
To get around this, you'll need to extract the values manually, something like:
protected void FormView1_ItemUpdating(object sender, FormViewUpdateEventArgs e)
{
// Get references to the controls
TextBox LastNameTextBox= FormView1.FindControl("TabContainer1").FindControl("TabPanel1").FindControl("LastNameTextBox") as TextBox;
// Set update parameters in datasource
ObjectDataSource1.UpdateParameters["LastName"].DefaultValue = LastNameTextBox.Text;
}
Since FindControl only searches the current naming container, you'll need to dig through each naming container (FormView, TabContainer, and TabPanel) to get to the TextBox.
Hope that helps.
Aaron
