Count Item retrieved in repeater or in transformation

Novice User asked on May 25, 2018 00:37

I need to count item retrieved by the document helper and if there are no documents returned I want to show a message. My options are

In transformation I am using {%DataItemCount%} but its not returnuing zero so that i can check it against an if condition like this {% if (DataItemCount < 1) {DataItemCount} #%}
How do you know how many item count are there in a basic repeater so that i can check that at the back end of a web part

or is there any other way to know no documents are returned ?

basic repeater tranformation

If there are no items returned there will be no transformation rendered. Use the zero items message text property to display a message for zero rows.

Repeater has property No Data Behavior, so there is no need to check it. DataItemCount - gets the total number of data items in the current transformation container. If everything was done correctly you should get the correct total. You macro should work

Thank you Brenden Kehren and Peter Mogilnitski for your input. Is there a way that I can get a count ? I need to make controls visible / not visible based on if the count = 0. I am also using a uni pager control and this condition

if (myUniPager.DataSourceItemsCount == 0)

is also returning zero always no matter how many records are there in basic repeater. Am i missing some thing here ?

What's the structure of your template? Are you using one datasource for multiple webparts?

I have a web part using a document query for e.g

var List = DocumentHelper.GetDocuments("my.something").Path(myPath);

and then i am using basic repeater to data bind it along with uni pager. so basically its one data source for a web part.
