Type
WideString

Remarks

The DefaultCaption property is used when a radio group serves as an in-place editor. It specifies the display value of the editor when none of the radio buttons within the group are selected. In ExpressQuantumGrid, this display value is used in the following two cases:

• When exporting grid’s data. Cells of columns that use the radio group editor are exported in the following manner. If a radio button is selected, its caption is written into the destination file (to the corresponding cell of the XLS file, for instance). If none of buttons are selected, the DefaultCaption property value is written to the corresponding cell of the target file.

• When using filter dropdowns for columns. The DefaultCaption property value is displayed within the filter dropdown of columns that use radio groups. When clicking this item, the grid displays only those records which have no radio buttons selected in the corresponding column.
