I'm using the xe:Listview component from the Extension Library. The columns are added to the control by using xe:ListviewColumn components. The data source is the xe:viewJsonService. Currently I have a total of five columns with three sortable columns (sort = true in the xe:ListViewColumns). But I would like to set the default sorting to one of the xe:ListViewColumns. Is this possible?
Try doing the default sorting from the REST service itself.
So on the xe:viewJsonService, add the programmatic name of the desired view column you wish to sort by default to the sortColumn property, e.g. sortColumn="LastName". Then set the sortOrder to ascending or descending, e.g. sortOrder="ascending".
But this scenario only works if the Notes view you are using for the REST service has sorting set on the column you want to sort, i.e. the LastName column though this column doesn't have to be the default sorting column from that view.
Hope this helps.

How can I set the ordering of my groups in Tabulator? It is not clear to me what determines which group comes first. I would like to be able to re-order the groups.
From Documentation http://tabulator.info/docs/4.0/group
Based on the order of array
groupBy:["gender", "color"], //group by gender then favourite color
It seems that the order of the underlying items is what orders the groups. So whichever group the first item belongs to will be the first group, and so on.
The order the groups are displayed on the table is determined by the sort order of the rows they contain.
The Row Management Pipeline Documentation shows that rows are first sorted, then grouped. This means that after sorting the rows Tabulator will iterate over the data row by row, creating groups as needed, so the group containing the first sorted row will be first etc.
So to reorder your groups, set the Initial Sort for the table
I have several views that have 'column totals' defined in some columns of these views. The totals can be in different positions in each view. I'm looking a for a fast, reliable way of identifying which columns have totals before I scan these columns and views.
Ideally, I want a 'isTotal' property on the column defintion (NotesViewColumn), but that property is not defined/available.
I can see that totals in the ColumnValues array does return a 'double' datatype where a column exists, but I can only see this once I've started scanning the data in the view, and I want this detail before I start looking at the data. (For information, the ColumnValues for a category notesViewEntry is an array containing: strings for cat columns, 'empty' for untotalled fields, and doubles for totals).
I can (of course) hard-code this detail somewhere, but it seems archaic to have to do this. I can 'getFirstDoc' to work out the ColumnValues in a 'pre-loop' check, but this seems 'wasteful'.
PS: I have seen something called 'ColumnValuesIndex' but this appears to be an undocumented feature which I would prefer not to use. However, if there were an 'isTotal' undocumented feature - I'd be ok with it!
The only solution I can think of to do this before you scan the data is to export the view design to DXL, then check the DXL for attributes or elements that specify whether each column shows totals.
I'm assuming view columns in DXL have an attribute or child element for this purpose. I haven't checked.
In case you've never done anything like this, using a NotesDXLExporter with either a NotesDOMParser or a NotesSAXParser, you can export selected design elements to in-memory DXL and programmatically analyse it.
As outlined in the original post, looking at the ColumnValues of a NotesViewEntry (NVE) on a category row does provide an array of values you can use to determine if any specific column is either a category string, empty, or a total. The totals have a datatype of double so stepping over the columns in a loop can easily flag the totals.
If the view has categories, then the first NVE in the view will give these details. A simple 'NotesView.GetFirstEntry().ColumnValues' will return the array. If the view has totals, but not categories, you can 'GetLastEntry' for the totals row at the bottom of the view.
Reading the totals is then just a case of looking for category rows (nve.IsCategory) and extracting the totals from the nve.ColumnValues.
Performance is reasonable and can be made a bit quicker by building a booleans array pre-loop of where the totals exist.
I have a shapefile in Spotfire and in the tableview of it I have a column displaying DenseRank. For example, if limit data by expression from the full 100 rows in the table to just 30, the DenseRank does not change. How can I perform this task?
Thanks,
Chris
Tableview does not allow dynamic calculations, unless you have a Document Property in the expression, The calculated column expression executes whenever Document Property value chane (or Calculations refreshed), for your scenario I think instead of using filter create a property control with Fixed values (10,20,30...100) or Values from a column (the one you are using to filter data). and use Document Property linked to the Property Control in your Calculated Column Expression .....
I found a workaround to dynamically rank data based on filtering or marking. If you create a data function as simple as "tableout <- tablein" then you can pass the original filtered and/or marked table to a new table. From there, insert calculated column on the new table and it will recalculate each time.
I've been trying to filter the view by second sorted column but so far it doesn't work.
(my underlying view is sorted by first column categorized and sorted by ascending, and the second column is sorted by ascending order as well)
How can i get through this thing? and I don't want to create one more view for this filtering
To filter by multiple keys you need to use a Java Vector with the keys you want to filter by. Here's an example of applying a filter to a sessionScope variable that you then use for the keys property of the view:
var vArray = new java.util.Vector();
vArray.addElement("key1");
vArray.addElement("key2");
sessionScope.put('viewFilter', vArray);
For search function, We have two different ways are there. One is normal search just like OS level.And another is Full index search.
Please follow the below link, U will get better idea,

Is there a way to create a SharePoint calculated column that returns a count of the number of entries in a list? So If I have 3 customers in my list with the company "Starbucks" I'd like the field to return "3"
(Edited some wording for clarity per suggestion from dariom).
You may be able to get what you want with another list using a not-so-well-known variation of a lookup column.
Let's say you have a list called Companies with values in the title column like "Starbucks", "Peets", etc. Now you also have the Customers list you refer to, but the "Company" column is a lookup column pointing to the title column in the Companies list.
You can add a count very similar to what you described to your Companies list. Go to your Companies list, add a column of type "Lookup" referring to the Customers list and you'll notice that in the drop-down area where you define the lookup if you point back to the Customers list, you'll have a new option called "Count Related". This is here automatically because it recognizes that the Customers list has a lookup pointing back to this one. Select that Count Related option and now your Companies list will have a column counting how many customers are associated with that company.
No coding, Javascript hacks, or anything. Just hidden SharePoint auto-magic.
No, I don't think there's a way to do this using the out-of-the-box calculated column.
Some other ways you could accomplish this are:
Create a view for your list that with a group by on the company field and include the total count. This is easiest, but might not be exactly what you're looking for.
Create a custom column type that executes a CAML query to find items that you're interested in. There is a learning curve if you've not done it before and if the list that you're adding this custom column to has lots of rows, you'll be executing a query for each row which is inefficient - it'll be OK for a small number of rows.
Use an event handler on the list that updates a column value each time a new item is added or removed from a list. This is easier, but can also be inefficient if you have a large number of items in your list.
As dariom said (damn my slow typing skills, +1!), only the current row can be operated on with calculated columns by default in SharePoint. There are a couple of documented workarounds involving SharePoint Designer or jQuery, though.
You can get a Count of specific list items in an XSLT Data View
To do this you will need SharePoint Designer.
Right click on your SharePoint List view (ensure the list view contains the field you want to filter by) select convert to XSLT Data View. Then in the Data Source Windows select Data Source Tab and drag and drop the field you want to get a total on for the specific items into where you want it displayed in your XSLT Data View. Click on the numerical value that is showing you should get a lightening bolt icon, select the drop down and choose Count, then select again and choose Filter. Select "Click here to add a new clause" then choose your field name again and enter your unique value as Starbucks and click OK, you can repeat this process for other fields you want the totals on. You will now see the total number of Starbucks items in the list.
I got something similar to work in a way similar to Niall. Basically, I:
Based on the source list, created a Data View Web Part (DVWP) on a "test" web
part page.
Added the footer column, which gives a count.
Set the filter for my conditions (i.e., the items I want to count).
In the code, deleted the recurring items row.
I was left with just the footer, which displayed a filtered count for all the list items. I further customized the footer by taking out the shaded background. Finally, I exported this web part and imported it onto the page where I wanted users to see a total of items in the list (which met the criteria).
