I have created a table named Card in the database and I want to add a check constraint to the Card_type column in pgadmin? How can I do it?
Card Types can be Debit_Card or Credit_Card.

As mentioned you want to add the card type in card table. So, I assume that you want to add the CHECK Constraint and add card type like 'Debit Card' OR 'Credit Card'. Which means that no other card details can be entered apart from the above two.
Steps:
1] Right click on the Card and select the Properties option which is at the bottom.
2] Select Constraint in that column
3] Click on the check option as shown in the image.
4] Add a new row by clicking the '+' option.
5] Type the Column name which you want to edit i.e Card_Type in the Name column
6] Click on the Edit row option and select Definition option.
7] Add the following code
"Card_Type"::text = ANY (ARRAY['Debit_Card'::character varying::text, 'Credit_Card'::character varying::text])
Click on Save button.

I'm working on a spreadsheet in Google Sheets for multiple people, and indicate in a column who the person the information on that row pertains to. I want to format cells on that column, only when they're not empty, based on what person is selected in another cell.
I can create functions to format things based on another cell's entry, but I don't know how to compound that with a function for not being empty. Sorry if this is super basic, I just can't figure it out.
Yep. This is a super simple thing to do.
1) Highlight the column where the person's name appears.
2) From the main menu, select Format, Conditional formatting.
3) In the sidebar click add a new rule. what you want to do is create one rule for each name that appears (or could appear) in that column.
4) Under "Format cells if, select "Text is exactly"
5) Type the name in the cell where it says Value or Formula
6) Choose a background colour to suit.
7) Click Done.
8) Repeat steps 3 to 7 for each person; but change the background colour in each case.
Here's an example.
I am manually creating a simple network in Cytoscape and I can create label and edge with names. But don't know how to add attributes to node or edge. For example, for a Student node, I want to add 'ID', 'age' as attributes of Student. I learnt that I need to use 'function builder to create a composite string and then use that column as your passthrough'. But exactly how to create a "composite string"? I can't find any example or tutorial on this. Thank you for your instruction.
To be clear, you don't want these as "attributes", you want to create a new label that includes all of these values, right?
So to do this, you would
go to the table panel and create a new String column
click in one cell of the column and then click the function builder [f(x)] icon in the row of icons at the top of the table panel.
choose the CONCATENATE function
for each column you want to concatenate:
select the name of the column and "Add" it
type a separator into the text field (e.g. ": ") and "Add" it
finally, make sure to click on entire column and then say OK.
You now have a new column with contains a concatenation of the columns you wanted. Just change the Label passthrough to point to that column.
I have tried finding any related event in docs, but there seems to be no such event. So is there any way I can trigger my code when user switches rows while editing.
My use case is :
On a particular combination of values in 2 cols of a row, I want to make 3rd col mandatory (otherwise its optional).
So whenever user changes any of first 2 cols and the combination matches, I want to show a message to fill 3rd column, but only if user switches to next row (Do not want to show the message in case users already were headed to fill the 3rd col themselves).
Did you try using afterCellEdit?

I have an Infragistics.UltraGrid and I want to add a right-click event on it. I have 6 columns in grid and when I click on last four columns of six I call context menu, but when I right click on first and second column nothing is happen.
By the way if I right click on first or second column and then right-click on other columns, my context menu disappear.
So can you please answer me what's wrong with first two columns?
I want to validate the size of the phone number field based on the selection made in the Phone Type field. Cell numbers should be 10 in size, Home and work numbers should be 11 in size. How would I write the constraint expression in Orbeon Form Builder. I tried using if in the constraint field, but was unsuccessful.
Thank you for your help!
Let's say you have two controls: a phone type and a phone number.
Create the phone type control, for instance as a drop-down or radio buttons. Give it a name, clicking on the cogwheel to open Edit Control Details. Say that name is phone-type. You will will refer later to the value selected by users as $phone-type.
Edit the items and keep in mind the value you assign to each item. The value is what you will use later, while the label is what is displayed to end users in the form. Say the values are work and mobile.
Create a single line control (text field), click on the red exclamation mark to open the Edit Validation Properties dialog, and there, under Constraint, write:
string-length(.) = (if ($phone-type = 'work') then 11 else 10)
