| Object Reference > True DBGrid Properties > RowCount Property |
This property returns or sets the number of rows in a RowBuffer object passed to an unbound event procedure for a TDBGrid control.
rowbuffer.RowCount= long
Read/Write at run time. Not available at design time.
In the UnboundReadData event, this property indicates how many rows the grid is requesting. After filling those rows by setting the Value and Bookmark properties, your event procedure should set the RowCount property to the number of rows actually fetched.
In the UnboundAddData and UnboundWriteData events, this property is always set to 1, since only a single row can be added or updated at a time. However, you can set this property to 0 to indicate that the add or update operation failed.
Note
When a RowBuffer object is passed to an unbound event procedure, the initial value of the RowCount property also specifies the maximum value. An error will occur if you attempt to exceed the maximum value.
