By default, the ElementFormat property is empty. Use the ElementFormat property to arrange in a different way the parts of the element. If the ElementFormat property is empty, the format of the elements is specified by the control's ElementFormat property. In other words, all elements can be formatted the same way using the control's ElementFormat property or separate way using the Element's ElementFormat property. 

The know parts of the element are:

• check, specifies the part where the element's checkbox is displayed. The ShowCheckBox property specifies whether the element's checkbox is shown or hidden. The CheckBoxAlign property specifies the alignment of the checkbox relative to the "check" part of the element.
• caption, specifies the part where the element's caption is displayed. The Caption property specifies the element's HTML caption. The CaptionAlign property specifies the alignment of the caption relative to the "caption" part of the element.
• extracaption, specifies the part where the element's extra-caption is displayed. The ExtraCaption property specifies the element's HTML extra-caption. The ExtraCaptionAlign property specifies the alignment of the extra-caption relative to the "extracaption" part of the element.
• picture, specifies the part where the element's pictures are displayed. The Pictures property specifies the element's pictures. The PicturesAlign property specifies the alignment of the pictures relative to the "picture" part of the element.
• extrapicture, specifies the part where the element's extra-pictures are displayed. The ExtraPictures property specifies the element's extra-pictures. The ExtraPicturesAlign property specifies the alignment of the extra-pictures relative to the "extrapicture" part of the element.
• client, specifies the part of the element where the inside ActiveX is displayed. The Control property indicates the inside ActiveX that hosted by the element.

The parts of the elements must be included between "" in order to be recognized by the CRD format.

For instance:

• "check" indicates that just the element's checkbox is displayed, so no matter if other are set the element displays just the checkbox ( if ShowCheckBox property is True ) and the element's Caption property.
• "check,caption" indicates that just the element's checkbox and caption are displayed, so no matter if other are set the element displays just the checkbox ( if ShowCheckBox property is True ) and the element's Caption property.
• "client" specifies that the whole element displays just the client part, so the inside Active control will use the entire background to display the inside ActiveX control. This indicates, that no caption, check or any other part is displayed on the element.
• "check":18,"client", displays the element's checkbox aligned to the left on a 18-pixels wide, and displays the client on the rest of the element.
• "18;"caption"/"client"", allows the element's Caption and the Control to be displayed.

The following samples show how you can display the element's checkbox next to the Command button.
