Column attributes enable developers to control the display, features, and behavior of interactive grid columns. Developers can use these attributes to alter nearly all aspects of column behavior, including altering the layout and appearance, creating validations, defining column links, creating column filters, and adding support for export and printing.

Some settings are configured at runtime by the report developer and saved as part of the primary or alternate report for example, column display order, the columns the report is sorted on, and column widths.

To learn more about save options, see " Saving Interactive Grids. The Property Editor displays the attributes for that column. Attributes are organized into functional groups. To view help for an attribute, select the attribute in the Property Editor and click the Help tab in the central pane. Different settings are available depending on the selected Type. In an editable grid, select the Type Display Only to make a column uneditable.

Choose the Type Hidden for primary key columns that should not be seen or other columns that are only used in templates such as icon or detail view, link targets, or columns of type HTML Expression. Selecting Yesenables users to use this column in sorts, control breaks, aggregates, and group by. Enabling these operations can cause performance issues, especially on large data sets or where appropriate column indexes are not available.

You can define an interactive grid column as a list of values to improve the speed of built-in filter tools. Use Column Attributes to create a link from a report to another page in your application or to a URL. The Link Builder - Target dialog appears. The Target Type you select determines the steps that follow. Note: Some settings are configured at runtime by the report developer and saved as part of the primary or alternate report for example, column display order, the columns the report is sorted on, and column widths.

Stack Overflow works best with JavaScript enabled.Most Application Express developers already have played with the Interactive Grid component introduced in the latest version 5. And indeed - Interactive Grid makes it more than easy to get an editable tabular form on a table or view.

In Page Designer, just drag the component onto your page, add the SQL query, make it editable in the Attributes section Interactive Grid for the EMP table. But with Interactive Grid you can do even more. In practice there is sometimes the requirement for a tabular form - but there is no table. The editing capabilities of interactive grid would come in handy here, but So at the first glance it seems that Interactive Grid cannot be used here.

Let's first have a look at the SQL query to be used as the region source. There is no table to select from - so we just generate rows Use that SQL query in order to create your interactive grid. Then navigate to the individual columns and change their settings as follows. Now run your page.

The preliminary result should look as follows. An interactive grid without a table - just with some generated data. Of course, you can further configure your interactive grid - just as you need it. But in this example, we'll now focus on the processing the end user inputs. Thus we'll be able to verify, that everything works as we expect it.

Create another Static Content region on your page below the interactive grid. The results of processing end user inputs will appear in the "Result" region. Thus we want to clear that element at the very beginning of processing. So create another process which is being executed before the Save Interactive Grid Data process. Finally turn off the Save button which has been automatically generated by interactive grid. We don't need that button here, because we want to submit the page when the end user has finished entering data.

As an alternative you also might to disable the toolbar completely - for such a form for data entry from scratch we might not need it at all. Disable the "Save" button or even the whole tool bar.

Now it's time to test what you have build. Run the page, enter data for a few rows and click the Submit Page button. The result should look as follows. Interactive Grid: enter some data from scratch. Thus interactive grid is much more than just a tabular form on a table; your application can do anything with the end user inputs. And, of course, you can also apply any client-side customization to the interactive grid.

But give a static ID to each column that you want to check what was triggered. Then use. Seem like we can not save a number Data Type value in the model. Maybe John Snyders-Oracle can confirm that? I have not followed all the code in this thread but in general the model doesn't care what data types you put in it but the rest of APEX expects data to be in string form so it is best to convert to a string.

Any idea? Hi Deb, Do you get an error? Regards, -John. Oracle Apex version 5. I tried your solution. Go to original post.Yup — JavaScript. Time to say Goodbye to those collections … Welcome JavaScript!

The following is a collection of simple JavaScript lines most likely to be needed by a developer wanting to customize an Interactive Grid, or access data elements in the Grid. This line gets the triggering element — the element that caused the dynamic action DA to fire.

Usually we want to do this in a Grid to get the value of a particular cell — the one clicked on in this case. The next line gets the grid widget. The apex. If you do not set one, a static id gets assigned, but it will be a long difficult-to-read identifier — it is much easier and better practice to set a meaningful static id, then use that meaningful static id in your code.

Given the Grid, we can now get the data model. The data set is referred to as a data model. The following line gets the grid data model. Given the grid data model, which we know is a table, we can get the record of the model, using our rowId which we identified via properties of the triggering element. Here my column name is COMM for commission.

The corresponding model. The above examples are easy on purpose. Now you know how to access a row id, access the grid widget, access the data model of a grid, access rows — records — in that data model, and how to get and set values of the columns in that data model record.

That covers most of the basics! You will need to learn more if you plan on complex customization or perhaps on building plugins. Looking forward to APEX 5. I highly recommend reviewing all of the examples in the Sample Interactive Grid packaged application. Nice write up. But as far as I see it, the model. Thank you Roel!

As I always give my columns a Static ID that is the same as my column name or alias I did not catch that. I have updated the post to reflect that. For those who are curious, read the comments in the model. To get the row id, we start with the triggering element. Happy coding! Like this: Like Loading Leave a Reply Cancel reply. Sorry, your blog cannot share posts by email.A very important point is that the information in this article applies to APEX version 5.

Some things may work in 5. Anyone programming Interactive Grid should move to 5. Part 3 covered a number of things you could do to control IG using actions or methods but often you want to do something in response to what the user does and that is where events come in. In addition to the standard browser events, UI widgets generally add their own higher level events.

For example any widget that has the concept of a current selection should have a selection change event. Widgets based on the jQuery UI widget factory have a common pattern for event handling where the event can be handled as either a callback function or an event.

You can learn about this from the jQuery UI widget factory documentation. What little information there is about the APEX widget events can typically be found in the source file comments after the event callback options property. The full event name is the name of the widget plus the event.

For example the pagechange event of the grid widget is gridpagechange.

The full name can be used as a dynamic action Custom Event or with the jQuery on method. The most commonly used widget events are exposed as Dynamic Action component events.

The Selection Change Dynamic Action event full event name: interactivegridselectionchange fires any time the selection changes. This applies to any of the views that support selection, which is currently grid view including single row view and icon view.

The underlying widget that implements the view such as the grid widget has its own selection change event but using the IG selection change event is preferred because it works for any of the views that support selection. The selection change event provides the apex. The event handler uses the model to set a hidden page item to the list of selected employee numbers and refreshes the chart region.

The chart region uses the hidden page item to select which employees to include in the chart. The Row Initialization Dynamic Action event fires when a row becomes active for editing. This event only applies to editable interactive grids. This happens after all the column items have been initialized from the model. The event is called apexbeginrecordeditit is not prefixed with any widget name and is not a callback.

It is not implemented by the IG widget but rather the table model view base widget, which is a base class used by other widgets such as grid.

Question (Sum of Amount in Interactive Grid in Oracle Apex)

One use for the row initialization event is to provide complex default initialization for newly added rows. The event is given the model, record, and record id of the active row. You can tell if the active row is inserted by looking at the record metadata. Create a dynamic action for the Row Initialization event on the IG region.

Add a JavaScript action. Set Fire on Initialization to No because that is what this event is already doing. Add the following JavaScript code. This technique of setting defaults can be used to work around an issue where columns that use a column type with distinct display and return values and with a static default end up showing the static return value for inserted rows rather than the display value.

This is a common issue with Switch column types. For example on added rows they show N rather than No. To solve this issue add a row initialization dynamic action similar to the previous example but with this JavaScript code.
