Hi!

I have an application where the user can create an article with one image chosen as the repsenting image of the article. The main image is shown as a thumbnail when all articles are listed. However the article can contain any ammount of images. 

So the user ahs to choce one image from the uploaded folder as the main image. Can i use an editor for that? I mean just the imageManager of the editor. Maybe i there is a better control?

Thank you!
Lautaro Arino.

Hi Lautaro ,

If you want to use the Image Manager as a standalone control, please, see this KB article:
Using the Image and Document managers outside RadEditor.

Thanks for the lightnhing fat reply!!! :D
Makes me very happy.


Thats alot of code!
Im not very good with JavaScript so i try to stay away from copy pasting this kind of solutions if possible. But there is no other image manager/documentManager in the RadToolbox is there?

Another question:
Can i use this solution to have the user select ONE image and then store it when the user presses ok. I dont want it inserted in the editor, i just want the user to pick one image.

Thank you!

Hello Lautaro,

I think that the File Selector Dialog example is exactly what you are looking for and will do the job.

The example shows how to create a simple File Selector Dialog. On Open button click a RadWindow containing a RadFileExplorer control is displayed. Once the user browses to a file and double clicks on it, a callback command is executed and the selected file path is populated in the textbox.

You can get the returned by the RadWindow dialog value and save it in your database and after that populate it in the article.




Sincerely yours,

Sounds perfect except for one detail. I would also need the possibility for the user to upload new images in the same dialog, as you can with the RadEditor. Any suggestions?

Thanks! Lautaro.

Hello Lautaro,

To enable the Upload feature of RadFileExplorer control you should set the UploadPaths property in the Configuration inner tag, e.g.

<telerik:RadFileExplorer runat="server" ID="FileExplorer1" Width="530" Height="500"
        OnClientFileOpen="OnClientGridDblClick">
        <Configuration ViewPaths="~/FileExplorer/Examples/Default/Images" UploadPaths="~/FileExplorer/Examples/Default/Images" />
    </telerik:RadFileExplorer>


The UploadPaths property is not set in this live demo, but you can set it manually in the RadFileExplorer declaration in your project.

All the best,
Rumen

Is it possible to make an image preview with codebehind?
I dont know why but when i try to make a event handler in codebehind i get "type or namespace FileExplorer could not be found"  even when im using 
"
using Telerik.Web.UI.FileExplorer;
using Telerik.Web.UI; 
"

i also try to make my eventhandler like this
"    protected void OnClientItemSelected(object sender, EventArgs e)
    {
        Telerik.Web.UI.FileExplorer xplorer = sender as Telerik.Web.UI.FileExplorer;
    }
"

but it doesnt work either. It doesnt recognize FileExplorer as a type.
Im still not using a registered version.

Hello Lautaro,

The RadFileExplorer control does not offer out-of-the box an Image Previewer. Nevertheless, if the EnableOpenFile property is set to true, then you can preview an image in the FileBrowser, by double click on it in the grid.
