XtraReport calculated field not working, always display zero - devexpress

I have created a summary calculated field sumMyField with Type Int32, the expression is Sum([MyField]), the column values are not 0, my others calculated fields in other reports are working correctly, but in this report the calculated field is always zero. I think it is relative to something like "cache". I cannot deleted the report and re-create it, as this takes too long to re-design

My solution is:
Delete the cell, recreate it and recreate the field to it. The calculated expression is correct!

Display label based on, field on one data-source (singular) being within another data-source fields many

I am still learning, and looking for help on how to display a label based on one data-sources field value, being within another data-sources field value list.
I have one calculated table, displaying rows of documents within a folder, and wish to use a field representing the document number in that data-source, so that if it's ANYWHERE within another tables field it displays my label.
I've been trying to use projection as I think this is how to achieve it.
I can get it working based on both the current #datasouce.item.fieldnames but need it to base the calculation on all possible numbers in that tables field (Image below should make it easier to understand).
I expect that it has something to do with projections, but can't find anything within the learning templates or anywhere else to resolve the issue.
I think the following should work for you. For the 'Reserved' label have the following binding for the text property:
(#datasources.project_quotes.items..quotenumber).indexOf(#widget.datasource.item.Qnumber) !== -1 ? 'Reserved' : ''
I would suggest alternatively just to include a field in your calculated datasource and making the determination in your server script.

Is it possible to filter the list of fields when outputting a Full Dataset?

I have a DataTable that I'm passing to a FlexCel report. It contains a variable number of columns, so I'm using the Full Dataset feature (e.g. <#table_name.*>).
However, only a subset of the fields are dynamically generated (I have a variable number of attachments). The column name for each attachment field starts with a common word (e.g. "Attachment0", "Attachment1", etc).
What I would like to do is output the known finite set of fields and then the variable number of attachments. It would be nice if I could write something like <#table_name.Attachment*> (and <#table_name.Attachment**>). Is there any way in FlexCel Reports I can achieve the same result?
A side benefit to such a solution means that I could keep the formatting for the known/finite set of fields.
Update
I added place holder columns to the document, each with a <#delete column> tag, so that the un-wanted columns/data are removed.
Although this works, it's not ideal. For example, if I want to see how the columns fit in the page width (in print preview), then I need to hide the columns. Then I have to remember to un-hide them again, so other developers can see/understand my handy work.
It would be much more straight forward if I could filter the fields before they're output to the document.
I realised there's an alternate way around this problem. I broke up the data into two sets of data - <#table_name.*> and <#table_name_attachments.*>.
The fixed set of fields are in the first table and the variable set of fields is in the second table (all the "Attachment*" fields). When the report is run, I place them next to each other (in the same order) in the same worksheet. This means I have two table ranges - "_table_name_" and "_table_name_attachments_" on the one sheet.
Now I'm able to run my print preview without hiding/re-showing the columns-to-be-deleted. I've also eliminated human error - it was all to easy to accidentally set the wrong number of padded/delete columns.

"Calculated columns cannot contain volatile functions like Today and Me" error message on Sharepoint

I try to add a new calculated column to sharepoint list that will show elapsed day. I enter name and write a formula like;
=ABS(ROUND(Today-Created;0))
The data type returned from this formula is: Single line of text
When I want to save I get an error like
Calculated columns cannot contain volatile functions like Today and
Me.
Calculated Column Values Only Recalculate As Needed
The values in SharePoint columns--even in calculated columns--are stored in SharePoint's underlying SQL Server database.
The calculations in calculated columns are not performed upon page load; rather, they are recalculated only whenever an item is changed (in which case the formula is recalculated just for that specific item), or whenever the column formula is changed (in which case the formula is recalculated for all items).
(As a side note, this is the reason why in SharePoint 2010 you cannot create or change a calculated column on a list that has more than the list view threshold of 5000 items; it would require a mass update of values in all those items, which could impact database performance.)
Thus, in order for calculated columns to accurately store "volatile" values like "Me" and "Today", SharePoint would need to somehow constantly recalculate those column values and continuously update the column values in the database. This simply isn't possible.
Alternatives to Calculated Columns
I suggest taking a different approach entirely instead of using a calculated column for this purpose.
Conditional Formatting: You can apply conditional formatting to highlight records that meet certain criteria. This can be done using SharePoint Designer or HTML/JavaScript.
Filtered List views: Since views of lists are queried and generated in real time, you can use volatile values in list view filters. You can set up a list view web part that only shows items where Created is equal to [Today]. Since you can place multiple list view web parts on one page, you could have one section for today's items, and another web part for all the other items, giving you a visual separation.
A workflow, timer job, or scheduled task: You can use a repeating process to set the value of a normal (non-calculated) column on a daily basis. You need to be careful with this approach to ensure good performance; you wouldn't want it to query for and update every item in the list if the list has surpassed the list view threshold, for example.
I found some conversations about this issue. Many people suggest to creating a new Date Time column, visible is false, default value is Today's Date and it will be named as Today. Then we can use this column in our formulas.
I tried this suggestion and yes error is gone and formula is accepted but calculated columns' values are wrong. I setted column Today is visible and checked, it was empty. Default value Today's Date was not working. When I looking for a solution for this issue I deleted column Today carelessly. Then I realized calculated columns' values are right.
Finally; I don't know what is trick but before using Today keyword in your formulas if you create a column named as Today and after your formula saving if you delete Today column, it is working.
UPDATE
After #Thriggle's answer I realized this approach doesn't work like a charm. Yes, formula doesn't cause an error when calculated column saving but it works correctly only first time, in the next day the calculated column shows old values, because its values are static as Thriggle explained.

How to list unique values of a particular field in Kibana

I am having a field named rpc in my elasticsearch database and I am displaying it using Kibana. When I search in search bar of kibana like:
rpc:*
It display all the values of rpc field but I want to have only those value to be displayed which are unique.
I have been playing around with Kibana4 since a couple of weeks now. I find it intuitive and simple and the experience has been great till now. Following your question, I tried getting unique results via a Data Table visualization. Why? Because I personally find it easier to understand. Following are the steps:
1. Get unique count
Create the visualization (Visualize -> Data Table). First lets get
the count of how many unique entries we have for a particular field
(We will use this in the later part for verification). I'm using
clientip.raw but as I see, it will work just fine with any friendly
field name too.
2. Set the aggregation right
Set you aggregation back to count and have a Split Rows as follows. Not doing this will give you count 1 for each field value (since it is looking for unique counts) when you populate the table. Noteworthy part is setting the Top field to 0. Because Kibana won't let you enter anything else than a digit (Obviously!). This was the tricky part. Hit Apply and you'll get the results. Unique field values and the count of each of them.
3. Verification:
Going to the last page of the table, we see there are exactly 543 results. This is how I know it works.
What Next?
You save this visualization and add it to a Dashboard. There you can always check the request, query, response and other stats.
Just an addition to the above mathakoot answer.
For the user of newer version (which do not allow bucket size of 0 anymore) just set a value greater than the maximum number of result
And report the value in the Options>Per Page field
I am using Kibana 6 so the UI looks a bit different than the older answers here.
Here is what worked for me
Create a visualization from your query, I used a line graph type (don't think it matters)
Under Data, set metrics aggregation = "Unique Count" and set field to your field.
Set x-axis aggregation = "Terms" and set field to your field.
Set Size > your number of records
Under Metrics and Axes, disable drawing of the graph, circles, and labels (this really helps the UI not lag)
Run query and then click "Inspect" and download CSV
Data
Metrics & Axes
I wanted to achieve something similar but I'm stuck with Kibana 3.1.
I simply added a panel of type "TERMS" and configured its Field = User-agent and left everything else on default values. This gave me a nice bar chart with one bar for each User-agent.

SSRS Tablix not returning full resultset

I have a tablix that is only returning the first row from a created dataset. I verified my stored procedure and dataset in asp and it's returning the expected results. Also I read somewhere to check the count of rows using a textbox and the CountRows() function and it indeed shows the expected count. Is there any special setting in the tablix or somewhere that I'm missing? Also if I add grouping, it would return the first row from each group which are several rows apart. This is really frustrating. Thanks in advance
If you deleted the row group it will do that. Or, if your row group is based on a single row value, that would be another reason. I had a limited result set coming back, and realized I was not grouping according to how I intended the report to behave and display.
Check to see if there is a filter on the Tablix, or perhaps you are grouping such that it only produced a single row? Please provide more information.
One of the reason I found for this issue is when a Matrix type of report (RDL) is converted to Tabular type of report by removing all grouped columns. To a developer it seems fine, but some where there is catch which does not convert a Matrix type report to Tabular and hence the grouping still continues and report never shows all the rows as expected. Only solution I found for this issue is creating a new RDL file of Tabular type and it all works fine.
