Wonderful :-)

And with the mediapicker I suppose it would be something like:

_dataExtractor = new DataExtractor();
_mediapicker = new mediaChooser(_dataExtractor);
MediaPickerPlaceHolder.Controls.Add(_mediapicker);

But how do I get the selected node id?

Best regards

dataExtractor.Value 

or

dataExtractor.Value.ToString()

Hi,

I have succesfully added the above code to the edit page of my custom tree.

But can anyone tell me, how a field that contains media data, should be formatted in a the custom table?

Why didn't you simply use the ContentPicker control (umbracon.controls.ContentPicker).. this would give you the media tree in a dialog.

Initialization of the picker works fine for me.  I create the picker and i create the extractor and set the value of the extractor and on the admin side it gets populated correctly.  Right now though, i cant seem to get the value after i change the value in the picker?  i keep getting null reference exceptions whenever i use dataextractor.value after changing the value of the picker

anyone experience this?

I have tried this aswell..

But I wanted to use the ContentPicker, but my problem was when I did the following:

 DataTypeDefinition dataTypeDefinition1 = DataTypeDefinition.GetDataTypeDefinition(1034);
 umbraco.controls.ContentPicker mediaPicker = (umbraco.controls.ContentPicker)dataTypeDefinition1.DataType.DataEditor;

 mediaPicker.AppAlias = "media";
 mediaPicker.TreeAlias = "media";

 PlaceholderMediaPicker.Controls.Add(mediaPicker);

I got a cast error, saying that my datatype was pagePicker, eventhough the database said the ID 1034 is the ContentPicker, anyone who can help with that?

After that I tried the example above, and got the mediapicker, but I cannot seem to get the value after I change the selection.

In either case I would like to be able to run a Javascript function after the select has been done, any input about how that could be done?

Hi Jacob,

Here you can find a good example how you can add the media picker to a custom section: http://our.umbraco.org/forum/developers/extending-umbraco/13518-implement-improved-mediapicker-c. It also places the datatype on a custom page.

Hey, allready tried those examples, and it is not an option for me to alter the souce code of Umbraco.

I got to the point where I have the mediapicker with:

private umbraco.editorControls.mediaChooser _mediapicker;

DataTypeDefinition dataTypeDefinition1 = DataTypeDefinition.GetDataTypeDefinition(1035);
umbraco.editorControls.mediaChooser _mediapicker = (umbraco.editorControls.mediaChooser)dataTypeDefinition1.DataType.DataEditor;

PlaceholderMediaPicker.Controls.Add(_mediapicker);            

Where the definition is in the top of the class, and the rest in the onInit override.

I can assign a value to it, and it has that when being drawn, but if I change the value, or just pushes a button which does a postback, then when I try to get the value in the onclick method I get "Object reference not set to an instance of an object."

Have I forgotten somthing obvious?

RE: Tim Gayssens' post. When the page is submitted, how do you get the value from the DataExtractor? On Postback the DataExtractor is being re-created and it's value is Null.

I've just worked out this simple solution based on a combination of the various comments in this post. (I'm using 4.7.2)

I've got a placeholder (phMedia) in my user control where I want the media picker.

In my 'Page_Load' function I define the following:

    umbraco.controls.ContentPicker contentPicker;
    contentPicker = new umbraco.controls.ContentPicker();
    contentPicker.AppAlias = "media";
    contentPicker.TreeAlias = "media";
    phMedia.Controls.Add(contentPicker);

To set the media picker to display the stored value:

    contentPicker.Value = myStoredValue;

To save the selected value in my 'save_Click' function:

    foreach (Control control in phMedia.Controls)
    {
        if (control.GetType() == typeof(umbraco.controls.ContentPicker))
        {
            umbraco.controls.ContentPicker contentPicker = (umbraco.controls.ContentPicker)control;
            myValueToSave = contentPicker.Value;
        }
    }

I hope this helps someone else!

I am getting null object reference error when I am trying to set value, I have tried just read  contentpicker and the above method , but I don't get the value

please help
