Accessing ListGridRecord from ComboBox

[dejan]

I have combobox which is mapped to DataSource and I can display data obtained from the server. I can easily access value and display field when user select some item.

However, I would like to access some other data from selected item which I can get from ListGridRecord. Is it possible to access selected ListGridRecord in combo box? I can use selected value to filter underlying DataSource and get ListGridRecord but is there more elegant way?

oups it seems that your question is the same that the one i have just posted.
Sorry for the doublons Isomorphic

Hi Guys,

SmartGWT is missing ComboBoxItem.getSelectedRecord() - we'll add this - you can call it via JSNI right now if necessary.

[olinsha]

thank you Iso ;)

[dejan]

Hm, I was looking for such method in SmartClient and I don't know how I missed it! :)
Probably because I expected ListGridRecord as result type instead of Object. I guess I can cast it to ListGridRecord, right?

[dejan]

If someone needs this functionality, here is the code I use in subclass of ComboBoxItem.

    public native ListGridRecord getSelectedRecord() /*-{
	    var self = this.@com.smartgwt.client.core.DataClass::getJsObj()();
	    var ret = self.getSelectedRecord();
	    if(ret == null || ret === undefined) return null;
	    var retVal = @com.smartgwt.client.core.RefDataClass::getRef(Lcom/google/gwt/core/client/JavaScriptObject;)(ret);
	    if(retVal == null) {
	        retVal = @com.smartgwt.client.widgets.grid.ListGridRecord::new(Lcom/google/gwt/core/client/JavaScriptObject;)(ret);
	    }
	    return retVal;
	}-*/;

Thanks for posting that dejan! We'll let you know when getSelectedRecord() lands in SVN.

Hi,
i encoutered the same problem, but getSelectedRecord() method into a child of CheckBoxItem does not work.
That did i miss.

Here the code i used:


public class ComboBoxItemBC extends ComboBoxItem {

public ComboBoxItemBC(String ch)
{
super(ch);
}

public native ListGridRecord getSelectedRecord() /*-{
var self = this.@com.smartgwt.client.core.DataClass::getJsObj()();
var ret = self.getSelectedRecord();
if(ret == null || ret === undefined) return null;
var retVal = @com.smartgwt.client.core.RefDataClass::getRef(Lcom/google/gwt/core/client/JavaScriptObject;)(ret);
if(retVal == null) {
retVal = @com.smartgwt.client.widgets.grid.ListGridRecord::new(Lcom/google/gwt/core/client/JavaScriptObject;)(ret);
}
return retVal;
}-*/;
}

@derferic Not sure you understand what this thread is about. This is a ComboBoxItem loading records from a related DataSource via the optionDataSource functionality. There is no analogy to CheckBoxItem.

[derferic]

Excuse me, for my bad explanation, effectively i use a ComboBoxItem (not a checkboxitem.. :) ) set via a datasource.
I need to retrieve the attached Record from the selected value.

After i picked up the value the returned selected record is alway null for me.

Thank

Exception calling getSelectedRecord

Hi,
I still have problem calling combobox.getSelectedRecord with last nightly build installed (495 13-May-2009 04:01).
My ComboBoxItem is bound with an optional data source and used as EditorType for a ListGridField that share the same optional data source, derived from a GwtRpcDataSource, with a custom ListGridRecord.
When I try to get the selected record in the ChangeHandler of ComboBoxItem or in EditorExitHandler of the ListGridField, the following exception is raised (in hosted mode IE + Windows Vista):

(TypeError): Proprietà o metodo non supportati dall'oggetto
 number: -2146827850

or the following in FireFox + Windows Vista:

Debugging the code I can see the native function in ComboBoxItem.class explained in this thread.

Any suggestion?

Thanks in advance,

For a JavaScript Exception, hosted mode stack traces aren't helpful. Can you get a stack trace from the SmartClient Developer Console in IE?

Unfortunately running in IE caused the following error during tab opening

In Firefox the same step is working fine.

I will try to workaround this error to get the combobox exception instead.
