Sitecore How to Get Control's Data Source Value - sitecore

Question

Is it possible to get __Rendering control's template field value on content item?
Especially, I'd like to get "Data Source" field value defined in control on page item, like below screenshot.
As shown in screenshot, I have some controls in page item and I'd like to get control's "Data Source" field value.
I used this code and I could list all controls using on the page item. But, I don't know how to get the control's browsed data-source information on the page.
public RenderingReference[] GetListOfSublayouts(string itemId, Item targetItem)
{
RenderingReference[] renderings = null;
if (Sitecore.Data.ID.IsID(itemId))
{
renderings = targetItem.Visualization.GetRenderings(Sitecore.Context.Device, true);
}
return renderings;
}
public List<RenderingItem> GetListOfDataSource(RenderingReference[] renderings)
{
List<RenderingItem> ListOfDataSource = new List<RenderingItem>();
foreach (RenderingReference rendering in renderings)
{
if (!String.IsNullOrEmpty(rendering.Settings.DataSource))
{
ListOfDataSource.Add(rendering.RenderingItem);
}
}
return ListOfDataSource;
}
RenderingReference[] renderings = GetListOfSublayouts(targetItem.ID.ToString(), targetItem);
List<RenderingItem> ListOfDataSource = GetListOfDataSource(renderings);

Answer 1

This is exactly what I wanted.
Perfectly working!!!!!!
public IEnumerable<string> GetDatasourceValue(Item targetItem)
{
List<string> uniqueDatasourceValues = new List<string>();
Sitecore.Layouts.RenderingReference[] renderings = GetListOfSublayouts(targetItem.ID.ToString(), targetItem);
foreach (var rendering in renderings)
{
if (!uniqueDatasourceValues.Contains(rendering.Settings.DataSource))
uniqueDatasourceValues.Add(rendering.Settings.DataSource);
}
return uniqueDatasourceValues;
}
}

Here is a blog post that can help: Using the Data Source Field with Sitecore Sublayouts
Here's the relevant code you can call from within a single control:
private Item _dataSource = null;
public Item DataSource
{
get
{
if (_dataSource == null)
if(Parent is Sublayout)
_dataSource = Sitecore.Context.Database.GetItem(((Sublayout)Parent).DataSource);
return _dataSource;
}
}
Accesing the DataSource property defined above will give you the item that is assigned as the Data Source from the CMS.
