TDBMemo.LoadMemo procedure
Loads the lines of text for the memo from the field in the linked data set.
Declaration
procedure LoadMemo; virtualDescription
LoadMemo is a method used to load the text for the control from
the field in the linked data set. No actions are performed in the method if
the value for the memo has already been loaded, the field in the data link
has not been assigned, or the field does not use the TBlobField field type.
LoadMemo signals the OnGetText event handler (when assigned in
the field data link) to get the Text value for the blob field. If OnGetText has
not been assigned, the AsString value for the blob field is retrieved. The
retrieved value is stored to the Lines property when it differs from the
existing value in Lines.
If an EInvalidOperation exception occurs while getting the value
for the control, the exception is caught and the message is stored in the Lines
property.
LoadMemo is called when the value in AutoDisplay is changed to
True, when the DataChange method is called, and when the
Enter key is handled in the KeyPress method.
Modified in LCL version 3.6 to update Lines when the field value differs from the existing value in Lines.
