Dynamically choosing gallery for image gallery control

Hi,

this is probably a very basic question, but I can't figure how to acheive the following: I would like to have on a page a combobox (RadCombo for example) holding a list of image galleries to be displayed, and an Image Gallery control that would just display the images of the gallery selected in the ComboBox.

How would you do this ? Is there a very easy way to acheive this, like with a small piece of javascript or a simple parameter ?

Thanks
Francois

Hello Francois,

You need a custom control for this implementation. Here is a basic idea.

1.Create a custom class that inherits from SimpleView
2. Create a template for your control that has RadComboBox declared in it and Repeater with ItemTemplate. Inside the ItemTemplate of the repeater add an Image control.
4.  In CreateChildControls of your custom control bind the combo to datasource of Albums

var ds = App.WorkWith().Albums().Get().ToList();

Then get the combo selected item or selected index and

- form the datasource of the repeater ( the Album has a method Images() which returns all items in the album)
you need to get a single album before that

var id = "guid of the album";
var alb= App.WorkWith().Albums().Where(a => a.Id = id).Get().FirstOrDefault();

- subscribe for ItemDataBound event of the repeater
- call DataBind of the repeater

4. Inside ItemDataBound event of the repeater you can access the ImageItem from e.data.dataItem and set the ImageUrl of your Image control declared in the control template.

I'm sorry Ivan, but if I've been using RadControls for several years, I'm completely new to Sitefinity and I just don't understand your answer.
Would you be kind enough to give a bit more details, or directions in the documentation for me to build a full sample ?

Buy the way, I don't want all the albums to be displayed in the RadCombo, but only a "manual selection" of albums...

Thanks for you help

Hello Francois,

You can take a look at How to crate a widget tutorial.

Here is a sample

Thank you, but it's not quite answering my question.
I do not wish to redeisgn my own image control, but I wante to reuse the Image gallery control (the lightbox version) by dynamically binding an album to the lightbox Image control.

It's a similar issue to this one (in SiteFinity 3):
http://www.sitefinity.com/devnet/forums/sitefinity-3-x/developing-with-sitefinity/how-to-bind-dynamic-a-library-to-imagegallery-control.aspx

How can you display specific albums, and at run time dynamically bind a lightbox image control to the chosen one ?

Hi Francois,

In this is the case you have to create a custom class that inherits from  Telerik.Sitefinity.Modules.Libraries.Web.UI.Images.ImagesView and override its CreateChildControls method without calling the base.

Wonderfull, thanks!

Now this is almost perfect.
But I can't find how to specify the Image Gallery type (for example the "Thumbnail strip + Image on the same page" type). I suppose it's just a property to set, but I can't find it!

Thanks for your help Ivan!

Hi Francois,

This is defined by MasterViewName .

Greetings,

Yes, this I have found...

But what I could not find is the possible values for the View Name !
When I make a call to LoadView, I need to know the correct value to specify.

this.LoadView("ImagesFrontendThumbnailsListLightBox");

This works, but what are the other possibilities ? What should be given to LoadView and MasterViewName in order to select the "Thumbnail strip + Image on the same page" ??

Hello Francois,

Below are the master view names that you can use

• ImagesFrontendThumbnailsListBasic - Thumbnails + Detail page
• ImagesFrontendThumbnailsListLightBox - Thumbnails + Overlay (lightbox)
• ImagesFrontendThumbnailsListStrip - Thumbnail strip + Image on the same page
• ImagesFrontendThumbnailsListSimple - Simple list

Thank you Ivan!

Hi again,

All of this is working perfectly and I would just like another precision to add on this.
Could you please tell me how to specify by code the sorting option that has to be used for the selectdc album ("As they are ordered in albums", or "Newest first",...) ?

Thanks, and Merry Christmas to all of you guys !

Francois

Hello Francois,

You can use SortingField property of the control.


SortingField.SelectedChoicesIndex

Can you please tell me were I can find this propertuy ?
I have created a class derived from an Imageview

Telerik.Sitefinity.Modules.Libraries.Web.UI.Images.

ImagesView

protected override void CreateChildControls()

this.MasterViewName = "ImagesFrontendThumbnailsListStrip";
var parentID = this.MasterViewDefinition.ItemsParentId;
this.MasterViewDefinition.ItemsParentId = AlbumGuid;
this.LoadView("ImagesFrontendThumbnailsListStrip");


How do I get access to the SortingField property from there ?

Hello Francois,

You can set MasterViewDefinition.SortExpression to

PublicationDate DESC
PublicationDate ASC
Ordinal ASC

This is what I need, but I don't understand where to create that class (in witch folder)? how to organize that code?

Please help,
Dragan

Hello,

Create  a custom class library and there you can create a C# class.

Sorry to ask what might seem obvious, like Dragan in the previous thread, I don't really understand how and where you create your custom class library and then class. I have created the class that inherits Telerik.Sitefinity.Modules.Libraries.Web.UI.Images.ImagesView like it was suggested a few threads above. But I don't see how to implement this on the page where I would like the Image Gallery to be placed. Can you please take me step by step to where and how its fully implementable? Thanks
