I'm using Infragistics ultragrid with only one band. In this band there is a string column with xx.xx.xxxx values. The column can have xx or xx.xx or xx.xx.xxxx value. I want to programatically groupby so the result will be hierarchy based. Have in mind that its not possible to change the datasource (or add columns).
as an example
90
90.00
90.00.0098
90.00.0099
99
99.00
99.00.0012
99.01
99.01.0013
and i want to groupby first on the 2 first chars (1st Level), then on the first 5 chars (2nd Level) etc
+90
+90.00
90.00.98
90.00.99
+99
+99.00
99.00.0012
+99.01
99.01.0013
Thanks in advance
You will need to add columns to the grid to group by them. This can be done either by added them to the datasource the the grid is bound to or by adding unbound columns to the grid and setting the values appropriately.

If I have column A receive 1000 rows of input and column B has some function that takes column A cells as input for some custom function. How do I control how many cells in column B can run at a time? For example
Column A receives input into rows 1-1000. Column B has rows 1-5 trigger. In order words, how to setup concurrency control for columns?
Edit: Referring to the picture - I will paste in 1000 cells of data into column A. I need column B to only process X rows/cells at a time.
based on your picture... if you want to process only 20 rows out of 1000 you could maybe try:
=ARRAYFORMULA(FUNCTION(A1:A20))
ofc if your Function supports the ArrayFormula variation
I have an Access table that has about 500,000 records. I want to trim down the results as I type text into the ComboBox. Basically, I need a dynamic ComboBox that displays records based on each character as I type into the ComboBox.
The problem is, the underlying table for the ComboBox has about 500,000 records.
And the ComboBox object can only display 65,000 records before it reaches it's limit, and won't preview the rest of the records. Nobody looks at 65,000 records at the same time but when any number in the middle of the entire record set is typed, the records won't display at all. Because that particular number is beyond the 65,000 limit. So i need a dynamic combobox for the whole table.
For example, if you are looking at a bunch of SSNs, instead of ComboBox displaying all the records which it can't because too many SSNs (more than 65,000 which is ComboBox limit) this is what I need.
If you type 5 in the ComboBox. The list would only display the 5-series of numbers. If you type 51 it limits the list values are the 51-series of numbers.
If you type 512 it limits the list values to the 512-series of numbers and so on. FOR THE WHOLE TABLE THOUGH, not just the first 65K.
WHAT I HAVE TRIED SO FAR is implementing a second unbound text box, however, this makes querying a two step process. I am wondering if I can just do it all together.
David W Fenton already provided a fairly detailed answer to this problem here. The gist:
The simplest approach is to assign the combo box's Rowsource only after you type some characters in it. You'd do that in the combo box's OnChange event
Allen Browne's Combos with Tens of Thousands of Records has some other bells and whistles (abstracting the logic into a function, preventing recalculation of the RowSource if the value hasn't changed), but the basic idea is the same:
Leave the combo's RowSource property blank.
Create a function that assigns the RowSource after a minimum number of characters has been typed. Only entries matching these initial characters are loaded, so the combo's RowSource never contains more than a few hundred records.
Call this function in the combo's Change event, and the form's Current event.
If you really want to successively filter the RowSource as each character is typed, you could adapt these answers to do that. For example, you could change the test condition in the David W Fenton solution to If Len(Me!cmbMyCombo.Text) >= 1. For the Allen Browne solution, you could set the constant to 1 and change the line that sets sNewStub to: sNewStub = Nz(sSuburb, "").
However, until your RowSource query is returning a chunk of numbers that is less than the row limit, you're not going to see any benefit. This is why both solutions linked above begin filtering after 2 (or 3 or 4) initial characters have been typed.
Hi to all i will try to tell you what i tried to do with an example. I have table as shown below;
#|a |b |c |
1|x1|y1|z1|
2|x2|y2|z2|
3|x3|y3|z3|
I want to create dynamic tablix for each row like below;
a|x1|
b|y1|
c|z1|
a|x2|
b|y2|
c|z2|
.
.
.
.
nth tablix.
I defined a dataset for a tablix. i defined the column names as row names(in the example they are a, b, c). and i can get the cell values by defining an expression like =First(Fields!x1.Value, "dsDetails") for each row. But i can not figure out how to generate dynamic tablix for remaining rows. I need suggestion to continue.
For others searching this kind of issue, there is a solution.You can create a tablix with two columns. First column will have the label you want to report and second column will have the information. The information can be displayed by inserting placeholders. An example table have been inserted below.
Example
If you inserted the table into a list. The report will be displayed for each row number.
PS: I fould this information on the internet. Therefore credits will go the the related person. This is just for the answer to be viewed here.
Another option is to use List control with Rectangle inside placing all columns of your dataset as separate textboxes inside that rectangle as it's shown in this video:
Using Lists in SSRS
I have a following employee table value as below :
name | cost
john | 1000
john | -1000
john | 5000
when we add the cost column total will be 5000.
I need to print only the 3rd row in BIRT report, since the 1st and 2nd row get cancelled out each other.
I'm stuck at filtering the table for above scenario.
Couldn't you just solve this using SQL like
select name, sum(cost)
from employee
group by name
order by name
?
Or do you just want to exclude two rows if they have exactly the same cost, but with different signs? Note that this is actually something different, take for example the three rows [ john|1, john|2, john|-3 ]? In this case, a pure SQL solution can be achieved using the SQL analytic functions (at least if you are using Oracle).
Elaborate your question. Its not clear if these are columns or rows.
If These are columns:
Create a computed column in your dataset
In Expression builder of that column add/sub values using dataSetRow['col1'] and dataSetRow['col2']
Add only that computed column to your table.
If these are rows
Select rows you don't want to print
Go to properties tab
Find Visibility property and click on it
Check Hide Element option
I have a requirement in ssrs report for display data like this.
I have to show 2 two rows data in one row in ssrs as shown below. Row count is unknown.
Please check another example.
Max two cell in one row in ssrs. I have to do this dynamically because I don't have any fix count in my data base table. If my table contain 3 rows it will display like first example but it it has 6 rows then it will looks like 2nd example.
Any suggestion how I can achieve.
The only way I know to do this left-to-right, top-to-bottom flow style is to sort of hack it in with lists. To my knowledge, the built-in controls do not directly support it.
First add a couple of columns to the query output to assign row and column numbers to each data row. (Change the order by clause as appropriate)
ceiling(row_number() over (order by AddressField) / 2.0) RowNumber
(row_number() over (order by AddressField) + 1) % 2 + 1 ColumnNumber
Now add a list to the report. Group by the RowNumber field. Within that list, add two more lists side by side. They will use the same dataset as the parent list. These will represent the cells. The left 'cell' will be a list with a filter ColumnNumber = 1. The right 'cell' will be a list with filter ColumnNumber = 2.
Now add textboxes within each 'cell' to contain the address data and format them as you desire.
