I can't seem to find anything on how to edit the data editor settings before umbraco 6.2 (Juno). Is there any simple way, it must be possible. If you don't understand what i mean i want to do the same as http://www.nibble.be/?p=96 - just for umbraco 4.5.2.
Thanks :)
You need to make 3 classes Class 1 DataEditor
public class DataEditor : System.Web.UI.UpdatePanel, umbraco.interfaces.IDataEditor
{
public MWCropperDataEditor(umbraco.interfaces.IData Data, string Configuration)
{
_data = Data;
}
public virtual bool TreatAsRichTextEditor
{
get { return false; }
}
public bool ShowLabel
{
get { return true; }
}
public Control Editor { get { return this; } }
public void Save()
{
this._data.Value = "data;
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
imageUpload = new FileUpload();
imageUpload.ID = "imageUpload";
//shows Image
cropImage = new System.Web.UI.WebControls.Image();
cropImage.Width = width;
cropImage.Height = height;
cropImage.ImageUrl = this._data.Value.ToString();
//Shows dropdown
locationDropDown = new DropDownList();
AddItemsToDropDown();
lblInfo = new Label();
lblInfo.Attributes.Add("id", "title" + base.ClientID);
lblCropInfo = new Label();
lblCropInfo.Text = "Crop Location: ";
base.ContentTemplateContainer.Controls.Add(lblInfo);
base.ContentTemplateContainer.Controls.Add(imageUpload);
base.ContentTemplateContainer.Controls.Add(new LiteralControl("<br/>"));
base.ContentTemplateContainer.Controls.Add(new LiteralControl("<br/>"));
base.ContentTemplateContainer.Controls.Add(lblCropInfo);
base.ContentTemplateContainer.Controls.Add(locationDropDown);
base.ContentTemplateContainer.Controls.Add(new LiteralControl("<br/>"));
base.ContentTemplateContainer.Controls.Add(new LiteralControl("<br/>"));
base.ContentTemplateContainer.Controls.Add(cropImage);
}
}
class 2 DataType
public class MWCropperDataType : umbraco.cms.businesslogic.datatype.BaseDataType, umbraco.interfaces.IDataType
{
private umbraco.interfaces.IDataEditor _Editor;

{
string[] value = Configuration.Split(new char[]{';'});
_txtWidth.Text = value[0];
_txtHeight.Text = value[1];
}
else
{
_txtHeight.Text = "100";
_txtWidth.Text = "100";
}
}
}
public void Save()
{
_datatype.DBType = (umbraco.cms.businesslogic.datatype.DBTypes)Enum.Parse(typeof(umbraco.cms.businesslogic.datatype.DBTypes), DBTypes.Ntext.ToString(), true);
string data = _txtWidth.Text+";"+_txtHeight.Text;
SqlHelper.ExecuteNonQuery("delete from cmsDataTypePreValues where datatypenodeid = @dtdefid",
SqlHelper.CreateParameter("@dtdefid", _datatype.DataTypeDefinitionId));
SqlHelper.ExecuteNonQuery("insert into cmsDataTypePreValues (datatypenodeid,[value],sortorder,alias) values (@dtdefid,@value,0,'')",
SqlHelper.CreateParameter("@dtdefid", _datatype.DataTypeDefinitionId), SqlHelper.CreateParameter("@value", data));
}
protected override void Render(HtmlTextWriter writer)

I hope this can help you get started :) Btw this also works for umbraco 6.2
Settings are called prevalues and you need a PrevalueEditor class that implements IDataPrevalue. Have a look at an example in this blog post:
http://www.eyecatch.no/blog/my-first-umbraco-datatype---part-2-rendering-a-recaptcha-control.aspx
This nibble post concerns doing a similar thing for v4.5 and prior, there is also a link within this for an even older version that I followed a while ago and found very helpful. http://www.nibble.be/?p=62
