Button Tag Pass-Through Attributes

Iron Speed Designer Pass-Through Attributes

These attributes control specific types of controls generated by Iron Speed Designer. Generally these attributes govern specific portions of code that is generated for your application depending on the selected attributes and their values.

Pass-Through Attribute

Description

CommandArgument

CommandArgument supplements the Command Name parameter in the Basic tab. The syntax and affects of individual arguments vary depending on various factors, including the URL / Command Name value, the button consumers' properties, table schemas, etc.

deleteonupdate

This argument is typically used when the Command Name is “DeleteRecord”. The selected record is hidden immediately, but not deleted from the database until / unless the consuming Table Control’s data is saved.

CommandName

The particular command to execute upon button click.

AddRecord	Add a new record to the database. Processing does not wait until a final “Submit” or “OK” button is clicked.
Custom	You can enter any command of your own.
CustomPostback	Disables the Ajax-based smooth panel update after clicking the control.
DeleteRecord	Delete the selected record from the database immediately. Processing does not wait until a final “Submit” or “OK” button is clicked.
ExportData	Export data from the associated table. A file selection dialog is displayed when an Export Data button is clicked, prompting the application user for a file name into which the data is exported.
FilterData	Perform a database query and display the resulting data in a table. This operation is normally used for a “Go” button in a filter field panel. The filter criteria are entered into separate text box and dropdown list fields.
GotoNext	Go to the next page in the table. The associated database query is executed and the next page of data is returned from the database and displayed in the associated table.
GotoPrevious	Go to the previous page in the table. The associated database query is executed and the previous page of data is returned from the database and displayed in the associated table.
LogOut	Sign out of the application. The application user is logged out.
Redirect	A new page, specified by the URL, is displayed.
Reset Data	Clears any data entered on the input form (page). Refreshes the records displayed on the table panel by performing a database query.
Reset Filters	Resets the filters including the Search, dropdown list box filters and the column sorting on table panels.
Search	Perform a search on the database. This operation is normally used for the “Go” button in a search panel. The search term is entered into a separate text box field.
UpdateData	Any input data on the page is updated in the database.

Consumers

Designates a “consumer” of the button event. When the button is activated, the application generates an “event” that informs other controls that the button has been clicked. This allows other controls to take action based on the event. This property designates which component, if any, receives the event.

None	There is no consumer of this event.
Page	The page consumes this event, indicating that all records on the page should be updated.
Parent	The parent control consumes this event.
ParentRecord	The parent record consumes this event.
ParentTable	The parent table consumes this event.

ControlToValidate

Specifies the target control to be updated when adding a new record via the Quick Add button feature. ControlToValidate is typically the name of the control of the dropdown list whose value is to be updated after a record is added via a Quick Add button.

The database field populating the dropdown list control is specified by the FieldValue pass-through attribute.

Applies To

Button
ImageButton
LinkButton

FieldValue

Specifies the name of the database field that populates the dropdown list updated by the Quick Add button.

Applies To

Button
ImageButton
LinkButton

ImageURL

The URL of the button image to be displayed.

PostBack

Specifies whether certain controls inside an Ajax-enabled update panel trigger a traditional post back. PostBack works in conjunction with the SmoothPanelUpdate pass-through attribute.

True	The button control triggers a traditional post back when clicked.
False	The button control triggers an asynchronous post back (Ajax-based smooth panel updating) when clicked.

Note: When the ‘Export data from’ button action is selected, PostBack is assumed to be True because this feature requires a traditional post back in order to function properly.

The PostBack pass-through attribute is not automatically generated; you must manually enable it. If PostBack is not present, it is assumed to be ‘False’.

Applies To	Button ImageButton LinkButton
Other	.NET Framework 2.0 and later applications.

RedirectArgument

URL arguments, if any, to pass to the page being displayed. There are several special arguments described in Button Bindings - URL Parameter Properties.

RedirectURL

The URL of the page to be displayed when the button is clicked. There are several special arguments:

Back

This argument can be used with the special RedirectArgument "updatedata", which is related to page history (Back key) handling.

You can modify a page’s OK or Cancel button to return "Back" to a previous page with fresh data by adding a RedirectArgument of "updatedata". This causes the previous page to load with fresh data, while maintaining settings (such as page size displayed, sorting, etc).

ASP.NET Control Properties

The ASP.NET controls have a wide variety of properties that can be used to govern the controls’ behaviors. You can enter any .NET control property into the Attributes tab and Iron Speed Designer will insert them into the generated control tags.

ASP.NET Control Property

Description

CausesValidation

The data entered into the page is validated by the application. All data in each data entry control on the page is validated.

true	The data entered into the page is validated by the application. All data in each data entry control on the page is validated.
False	The data entered into the page is not validated by the application.

Text

The text to display in the button or link. This applies only to Link Buttons and Push Buttons.

ToolTip

Pop-up help text displayed when an application user moves their mouse over the button.

PostBack pass-through attribute set to ‘True’ in certain cases

When a field is bound to a third-party control (e.g, FCKeditor) a postback may be necessary to retrieve the current field value. This is not a problem when page content is saved by clicking the ‘Save’ or ‘Save and New’ button which belongs to page, but it could be a problem for table row buttons. To avoid such problems, Iron Speed Designer adds the ‘PostBack = True’ pass-through attribute to all ‘Save’ and ‘Save and New’ buttons by default.

Pass-through attributes of buttons within ASCX controls

Pass-through attributes are declared differently for a Text button (so called ‘theme button’) and an Image button. For example the CommanName pass-through attribute for a text button is Button-CommandName whereas it is just CommanName for an Image button.

The reason is that theme buttons are usually ASCX controls that are within a page (ASPX). A button component creates a reusable panel and is based on a layout that you can specify. The PushButton, LinkButton and ImageButton are standard HTML buttons. In order to retrieve the pass-through attribute for any ASCX control within a page, it is essential to prepend the name of the ASCX control before the pass-through attribute so that the page is aware it refers to the pass-through attribute of an ASCX control with that name. Image buttons, on the other hand, are simple ASP controls and therefore don’t require us to specify the name of the controls before the pass-through attributes.

The Button uses several pass-through attributes to set the values of attributes inside of the Button panel. The attributes whose names are prefixed “Button” refer to the attributes within the Button panel. For example, a code generation tag named Button within the Button.html panel is referred to by the name Button by the enclosing page or panel. As such, the Button-CausesValidation pass-through attribute refers to the CausesValidation attribute of the code generation tag named Button within the Button.html panel.
