The Repeater control is used to allow access to sets of data stored in a database. The data to be displayed is requested from the Data Source to which the control is bound to and the control displays copies of the controls it contains for each row returned in a data page.

This control can replace the Form and SubForm combination for displaying lists of records that are related to some other information that the developer wishes to display on a form. One of the most common uses is in implementing master-detail type views.

Properties

Property Description
Alignment The Alignment property is used to align the Caption text with the left, right, or center of the Control.
Backgnd Image The Backgnd Image property specifies an image to be displayed in the background of the object.
Border Color The BorderColor property specifies the color that should be used for drawing a rectangular border around the Control. Note: the border will not be visible unless the BorderStyle and BorderWidth properties are also set.
Border Sides The BorderSides property specifies the parts of a control's border that are displayed.
Border Style The BorderStyle property of the control defines how and if a border will be drawn around the control.
Border width The Border Width property specifies the line width used to draw the rectangular border around the Control. Note: the border will not be visible unless the BorderColor and BorderStyle properties are also set.
Color The Color property specifies the background color of the Control.
Cursor The Cursor property, if set, causes the appearance of the mouse cursor to change as it moves over the Control.
Data Source Most XApps need the ability to display database records to the user. The most common way of accomplishing this is to use a data-bound Form, Report or a Repeater control. A form or report can be made data-bound by setting its Data Source property to the table or query containing the data to be displayed. The data can reside in the built-in .MXD database or an external database. If the user needs to be able to edit the data, a single or continuous editable form must be used; otherwise a continuous form, Repeater control or a report is generally used.
Enabled If the Enabled property is set to false, the Control's state or value cannot be changed by the user.

Note For Timer Control: This property controls whether the Timer event will be triggered at the time interval specified in the Interval property. If the Enabled property is set to false, the Timer event will not be triggered.

Font The Font property (and its sub-properties Color and Name) is used to indicate which font should be used for drawing the text in the Control.
Height The Height property specifies the vertical extent of the Control. Note: if the CanGrow or CanShrink properties are set, the actual height of the Control at run time may be different.
Hint The Hint property, if set, specifies the text of a tooltip that is displayed when the user moves the cursor over the control.
Horizontal Placement The HorizontalPlacement property, if set, governs how the Control adjusts its size and position in response to changes in the horizontal dimensions of its parent.
Left The Left property specifies the horizontal position of the Control in the form.
Margins The Margins property clears an area around control (outside its border).
Max Length The MaxLength property specifies the maximum number of characters that the user can enter in a textedit control.
Name The Name property specifies the identifier used to reference the control from browser- or server-side code.
Opacity The Opacity property determines the extent to which the Control obscures any controls placed in its background. A value of 0 means that background controls are fully visible, whereas a value of 100 means that background controls are completely obscured.
Padding The Padding property specifies the space between the border and the content of the editor.
Read Only If the ReadOnly property is enabled, the user is able to select, but not modify, the content of the TextEdit.
Shared Style The SharedStyle property can be used to force several controls always have the same appearance.
Shrink On Hide The ShrinkOnHide property specifies how Morfik's Layout engine repositions other controls when the container's visibility is changed at runtime.
Tab Order The TabOrder property allows the developer to specify the order in which controls should receive input focus when the user steps through them using the tab key.
Tag The Tag property is used to store user data that is associated with the control.
Text The Text property for the control allows direct access for setting or reading the text that is currently in the control. This property can be bound to a database table field as to automatically display its contents and allow editing of them.
Top The Top property specifies the vertical position of the Control in the form.
Vertical Placement The VerticalPlacement property, if set, governs how the Rectangle adjusts its size and position in response to changes in the vertical dimensions of its parent.
Visible The visible property is used to make controls visible or invisible. Invisible controls are frequently used to allow for easy access to information from a database table field, if the control is bound to one.
Width The Width property specifies the horizontal extent of the Form/control.

Events (browser-side)

Event Description
On After Grow Or Shrink This event is fired within the browser after the height of a control is adjusted in order to fit its new content.
On Before Grow Or Shrink This event is fired within the browser before the height of a control is adjusted in order to fit its new content.
On Blur Event This event is fired within the browser when a control loses focus either by the pointing device or by tabbing navigation.
On Click The most commonly used event for a TextLabel control is the OnClick event, which should be handled to execute whatever action is intended when a control is clicked.
On Double Click This event is fired when the user clicks on a control within the browser.
On Focus This event is fired within the browser when a control receives focus either by the pointing device or by tabbing navigation.
On Hyperlink Click This event is fired in the browser just after a hyperlink is clicked and before the requested navigation is carried out.
On Mouse Down This event is fired within the browser when the mouse button, or any other pointing device button, is pressed while it is over a control. On a PC-based mouse, it specifically relates to the left-hand mouse button being depressed.
On Mouse Out This event is fired when the mouse pointer, or any other pointing device button, is moved out of the region defined by a control.
On Mouse Over This event is fired when the mouse pointer or any other pointing device is over (within the region defined by) a control.
On Mouse Up This event is fired within the browser when the mouse button, or any other pointing device button, is released over a control. On a PC-based mouse, it specifically relates to when the left-hand mouse button is being released.
On After Pushed Or Pulled This event is fired within the browser after the position of a control has changed in response to a change in the content of a sibling control.
On Before Pushed Or Pulled This event is fired within the browser before the position of a control is changed in response to a change in the content of a sibling control.

   

Events (server-side)

Event Description
On After Print This event is fired on the server by a Control after its HTML (or in the case of Report generation, PDF) content is generated.
On Before Print This event is fired by a control on the server before control’s HTML (or in the case of Report generation, PDF) content is generated.
On Print Style This event is fired on the server to allow for CSS style changes when the HTML representation of a control is being constructed.

   

Remarks

Data Binding

Through the use of the Data Source property you can associate a Repeater control with a specific data source, regardless of the data source being used by the form the is placed on. Once a repeater control has been set, all references set through the use of Data Field property to bind controls such as the TextEdit control to specific data fields will be matched against the control's data source allowing the developer to display or edit information associated with a field in that Data Source.

This feature is a departure from how Morfik's visual development worked previously to version 3.x. All database aware features of Morfik 2.x are preserved but this control considerably pushes the boundary of how much data can be displayed within a single Form. This helps drive down the number of forms in a project.

Note: Allowed only one level of nesting - a repeater inside a form.
