Radio Button Groups

Definition

The Radio Button Group Web item puts characteristic values to be filtered into a group of selection buttons.

Use

Using the Radio Button Group Web item, you can easily filter one or more connected data providers by a characteristic value. When you select a value, the connected data provider is filtered according to this value. If you select a filter value in another way for the characteristic of the radio button group, the current filter value is selected.

Structure

The following is a parameter list for the Web item Radio Button Group, arranged according to the various parameter groupings.

Display

Parameter	Description
Width in pixels (WIDTH)	You use this parameter to determine the width of the Web item.
Height in pixels (HEIGHT)	You use this parameter to determine the height of the Web item.
Visibility (VISIBILITY)	You use this parameter to determine whether the Web item is visible in the Web application.
With tray (WITH_TRAY)	You use this parameter to determine whether the Web item has a symbol that enables it to be expanded and collapsed in the Web application. For more information on this parameter, see Parameter Tray.

Internal Display

Parameter	Description
Label (LABEL_VISIBLE)	You use this parameter to determine whether the long text of the characteristic is written as a label in front of the radio button group.
Maximum text length (TEXT_MAXLENGTH)	You use this parameter to determine the maximum text length for the values. Specify the number of characters for this.
Maximum number of displayed values (ENTRIES_MAXCOUNT)	You use this parameter to determine the maximum number of values that are to be displayed in the radio button group.
Entry display ALL (ALL_VALUE_ENTRIES_INCLUDED)	You use this parameter to determine whether the All entry is displayed as a selection option in the radio button group.
Number of columns (COLUMNS)	You use this parameter to determine the number of entries displayed adjacent to one other.

Behavior

Parameter	Description
Activate navigation (INTERACTION_ALLOWED)	You use this parameter to determine whether navigation and other interactions are possible, like in the Web application.

Data Binding

Parameter	Description
Data provider (DATA_PROVIDER_REF)	You use this parameter to assign a data provider to the Web item. The Web item gets the data and metadata that it needs to generate the output and commands from this data provider. We recommend that you keep to the conventions supported by the Web Application Designer when specifying names: The name should be a maximum of 30 characters long and consist of characters “A-Z”, “0-9” and “_”, but cannot start or end with “_”. Adhering to these conventions facilitates the upgrade to future SAP releases.
Affected data provider (LINKED_DATA_PROVIDER_REF_LIST)	Under this parameter, you create a list of data providers to which all commands are sent. For each entry in the data provider list, you choose a data provider under the Affected Data Provider parameter (LINKED_DATA_PROVIDER_REF). Note that you cannot create data providers in the parameter dialog, you have to create them beforehand.
Characteristic (CHARACTERISTIC)	You use this parameter to select the characteristic by technical name.
Read mode (DATA_READ_MODE)	You use this parameter to determine which values from the master data table are to be transferred to the Radio Button Group Web item as filter values. (M): All values from the master data table. In some circumstances, values that do not appear in the data provider under the current filter conditions and that, upon filtering, produce the result “No Suitable Data Found” are also displayed. However, under certain conditions this process is the fastest. (D): Values that are basically posted, whereby the current drilldown status is not fully taken into consideration.‑{}‑ (Q): Only values that are also posted in the data provider under the currently valid filter conditions are displayed. Under certain circumstances it can take a long time. Read mode for Web items to set filter values: The “master data” read mode may lead to many unposted values being displayed; the “posted values” read mode may be slow.
