I wanted to know if there are any methods to do data cleansing in Kylo (https://kylo.io/). I was able to get the tool to point out errors using data validation rules, but I was curious to know if it can also perform other functions. Examples:
Deleting any empty records in between the data
Detecting and deleting duplicate columns in the data
Data cleansing is handled in Kylo using standardizers and validators. However, as of Kylo 0.9.0 there's no built-in functions for removing empty rows or duplicate columns. The current functions are limited to removing rows if a specific column is empty and removing duplicate rows.
This functionality could be added by writing a plugin:

We are using a very old version of devexpress (version 11.something). I am trying to use the "ordering" functionality on a pivot grid.
What is the area called in the red circle.
How can I specify the number of columns allowed in this area.
When more than n number of columns, the functionality disappears, how can I avoid this
Setting up a pivot table via the web reporting tool, you must specify all levels of rows that are to be used. There is a use case where the rows displayed or used to show the data makes sense to dynamically set, or switch around. Is this possible, or does the whole web report need to be edited? (The equivalent of editing a pivot table rows in Excel)
Im trying to add a summary row which sum all values in each column. I have very large data and I do pagination in the grid. However, I heard gwt doing summaryGrid in client side which does not work in my case. I tried to setShowGridSummary to true but it works only for a small set of data, it shows blank if the data is large. So I want to change the plan to add additional summary grid and then get the query from backend and insert the summary data into that grid. So my question is can I add additional row into smartgwt grid? And how?
Thanks,
On client side SmartGWT can only calculate summary if you fetched all records so only then summary values will show.
You can disable pagination and do this which I don't recommend for large data sets. Or prepare another data source that can calculate summary on server side and return only one record:
listGrid.setSummaryRowDataSource(summaryRowDataSource);
SmartGWT will make another request to server for summary row with same criteria that was used for normal fetch.
It will be also refetched any time criteria will change.
This probably has a simple answer, but I've been looking all over and can't find anything to suit my needs.
I've been using gridviews to display data, but new customer requirements call for the user to be able to select individual columns, rows, or cells. Does anyone know of a good option?
Thanks.
EDIT:
Essentially, I'm displaying several rows of data, each row comprised of multiple columns. With standard gridviews you can't really select all the data in one column without selecting data from the other columns. I need a way for the user to select one column worth of data so that they can copy the data out.
