Get NodeID in a Filter Control

Eric Garrison asked on March 22, 2016 15:38

I am having an issue with a Custom Control (ascx.cs) file and could use assistance. The only issue I am having is getting the NodeID of the page I am on. The control needs to populate a drop down with sub categories. That works fine if I hard code my NodeID, but I am not having any luck getting the NodeID of the page.

The page is a standard page in the PORTAL engine. What is the syntax and command for NodeID in ASCX.CS?

nodeid filter custom control

Hi Eric,

Just use DocumentContext.CurrentDocument.NodeID

Hello,

If your control inherits from FormEngineUserControl, you can get NodeID by this

ValidationHelper.GetInteger(Form.GetFieldValue("NodeID"), 0)

or did you tried with CurrentPageInfo.NodeID ?

I am getting an error. Here is my code. When I uncomment nodeID=1458, and remove your code, it works. I did declare the nodeID as INT above this.

String dataDB = "Kentico9";

QueryDataParameters qdp = new QueryDataParameters();

nodeID = ValidationHelper.GetInteger(Form.GetFieldValue("NodeID"), 0)

///nodeID = 1458;

qdp.Add("NodeID", nodeID);

DataSet ds = ConnectionHelper.ExecuteQuery(string.Format("{0}.dbo.GetCycleTypeList", dataDB), qdp, QueryTypeEnum.StoredProcedure,true);

Eric,

Have you looked at all at using the DocumentContext object for this instead? If you are on 8 or 9, I would really recommend that. You could then use the DocumentContext GetValue to get the NodeID in that? It is a more efficient way of getting this in these versions.

Sorry I cannot give 2 correct answer votes.

Here is what I added: nodeID = ValidationHelper.GetInteger(DocumentContext.CurrentDocument.NodeID,0);

Make sure you have using CMS.DocumentEngine; in the top of your ASCX.CS

Eric,

It's not necessary to use ValidationHelper.GetInteger here, because DocumentContext.CurrentDocument.NodeID returns int value.
