BAQ DataView in Dashboard

I am not very familiar with BAQ DataViews, but I did do some digging and it looks like it’s relatively painless to set up the dataview and bind it to the transaction object within a form. It looks like then, you subscribe the data in the BAQ dataview to a column(s) in another view to relate the data.

I have a dashboard assembly that already uses some pub/sub dashboard features in order to drive the data in the different panels.

The end goal is to bring in a new column into one of the queries/panels with the results from a separate BAQ. These are currently (and will likely remain) 2 distinct BAQs.

The first BAQ returns data with the QuoteDtl_QuoteNum field as key. I want to relate the second BAQ (the BAQDataView data) on QuoteNum as well, and then return a column from its data and meld them together in the grid.

I am having trouble getting the thing to work however.

Here is my dataview code:

private void CreateOrderBucketsView()
		//Connects the BAQView to the EDV on Quote Num
		baqViewOrderBuckets = new BAQDataView("OPS_OrderBuckets");
		oTrans.Add("OrderBucketsBAQView", baqViewOrderBuckets);
		EpiDataView edvQ = (EpiDataView)oTrans.EpiDataViews["V_JRF_Quotes_1View"];
		string pub1Binding = edvQ.dataView[edvQ.Row]["QuoteDtl_QuoteNum"].ToString();
		IPublisher pub1 = oTrans.GetPublisher(pub1Binding);
			string pubName = Guid.NewGuid().ToString();
			oTrans.PublishColumnChange(pub1Binding, pubName);
			pub1 = oTrans.GetPublisher(pub1Binding);
			baqViewOrderBuckets.SubscribeToPublisher(pub1.PublishName, "QuoteHed_QuoteNum");

From my understanding, the pub1Binding variable stores the name of the column in another dataview that I will be relating the data from the BAQ on.

I tired calling this during the InitalizeCode(), but it fails to work, probably because there is no native dataview value to bind to.

I’m sure I’m doing something wrong, but any guidance would be very much appreciated!

@Carson I used your code and watched your video, much appreciated by the way

I don’t have a definitive solution for you. But you could try replacing the line below. As you said, at initialization the view may not be loaded yet. Setting the value to a string might get around that.

string pub1Binding = "V_JRF_Quotes_1View.QuoteDtl_QuoteNum";

Also, make sure your BAQ OPS_OrderBuckets does not have any parameters defined. This has gotten me in the past.

Good luck! I am curious what solution you find!
