          <p>
            <var>TColumn</var> is a <var>TGridColumn</var> descendant that represents a display column in a database grid control. TColumn provides properties and methods needed to access and mantain the Dataset, Field, FieldName, and DisplayFormat for the column.  TColumn provides overridden functions which implement facilities from the ancestor class.
          </p>
          <p>
            TColumn instances can be created at run-time or design-time;  properties are provided to indicate when the instance was created. The display order for columns need not correspond to the order of the Fields in the dataset, nor do all Fields in the dataset need to be represented by a display column.
          </p>
          <p>
            TColumn instances are used as the collection item for the <var>TDBGridColumns</var> collection.

SetCurrentField calls GetGridColumnFromField to    ensure that the Field in AValue becomes the current column in the control. No actions are performed in the method when AValue contains the  same value as the SelectedField property.

            <var>SetDataSource</var> is a procedure used to set the value in the DataSource property. SetDataSource is the write access specifier for the DataSource property. SetDataSource stores the value in AValue in the DataSource property for DataLink, refreshes the column widths for the control, and calls UpdateActive.

        <descr>
          <p>
            <var>SetOptions</var> is a procedure used to set the values in the Options property. SetOptions is the write access specifier for the Optoions property. SetOptions causes other aspects of the grid control to be updated to reflect changes in the property value. ChangedOptions is updated to reflect the enumeration values added or removed in the request. Some enumeration values force other features or behaviors to be disabled. For instance: row selection. Enabling row selection forces the options for editing, always displaying the editor, and row highlighting to be removed from the Options property. Finally, removing multi-selection from the Options property forces the SelectedRows and KeyBookmark properties to be cleared.
          </p>
          <p>
            AValue is a TDBGridOptions argument that specifies features or behaviors that will be enabled or disabled in the grid control. Please note that these options are different than the TGridOption values used in the ancestor class.
          </p>
          <p>
            As a result, SetOptions must translate any TDBGridOption values to their TGridOption equivalents and store them in the inherited Options property.
          </p>
          <p>
            Options contains the following default values when the control is created:
          </p>
          <ul>
            <li>dgColumnResize</li>
            <li>dgColumnMove</li>

          <p>
            <var>UpdateBufferCount</var> is a procedure used to set the number of records buffered for the linked dataset. UpdateBufferCount requires that DataLink be marked as Active to set the  buffer count. If DataLink.Active contains False, no actions are performeds in the method.
          </p>
          <p>
            UpdateBufferCount calls GetBufferCount to determine the number of rows that can be displayed in the control with the DefaultRowHeight. When Options includes the value dgTitles, the buffer count is decreased by 1 to account for the fixed title row. UpdateBufferCount stores the new value in the BufferCount property in DataLink.
          </p>
          <p>
            UpdateBufferCount is called from the UpdateGridCounts method.

            <p>
              UpdateData ensures that the appropriate method is used to update Field data based on the TField.FieldKind for the modified column. Special handling is provided for lookup Fields to check the cached lookup list or to retrieve the  lookup result using its key Fields.
            </p>
            <p>
              UpdateData calls the EditingColumn method to disable the editing flag for the column prior to exit.

            <var>GetColumnCount</var> is an Integer function used to get the number of visible columns or Fields for the grid control. GetColumnCount uses the Columns collection (when its has been Enabled) to get the value in VisibleCount.

            DoLayoutChanged calls BeginUpdate to signal changes to the control, and UpdateGridCounts to determine the number of rows for the update. When  UpdateGridCounts returns 0, the EmptyGrid method is called to clear the grid control. DoLayoutChanged calls EndUpdate to allow pending changes to be applied to the control. DoLayoutChanged calls UpdateScrollbarRange to update scrollbars (when used) for the control.
          </p>
          <p>
            DoLayoutChanged is called from the EndLayout method.

          <p>
            <var>BeginLayout</var> is a procedure which starts producing layout changes for the grid control. BeginLayout is used along with EndLayout to minimize the number of times layout changed notification events are triggered by the control. Layout changes occur when the control enables certain values in its Options property, when AutoAdjustColumn is called, and when the Columns collection links to Fields in the associated dataset.
          </p>

            BeginLayout increments the LayoutChangedCount variable that tracks the number of times the method is called for the control. <var>EndLayout</var> decrements that counter and when it reaches 0 (zero) the DoLayoutChanged method is called.

For checkbox columns, the DrawCheckBoxBitmaps is called. For columns with a button-style editor, the DrawButtonCell method is used. For Fields with a ftMemo data type, the CheckDisplayMemo method is called to determine whether the content in the memo or the DIsplayText for the column definition is drawn. Finally, the DrawCellText method is called to draw the specified cell using its state and value.

            <var>GetEditText</var> is an overridden String function used to get the Text value for the Field at the specified Row and Column.
          </p>
          <p>
            GetEditText requires that the linked dataset for the control be active to access its Field definitions. GetEditText calls the GetFieldFromGridColumn method to get the TField instance that provides the textual representation of the value for  the Field. GetEditText calls the CheckDisplayMemo method to determine if a Field with the ftMemo data type displays its content or the string literal in its Text property '(Memo)'.

          <p>
            Columns is a TDBGridColumns property that provides access to columns defined for the database grid control. Items in the Columns collection are represented as TColumn instances and can be explictly created in the IDE at design-time, or automatically added when the OptionsExtra property includes the value dgeAutoColumns.

        <descr>
          <p>
            <var>DataSource</var> is a TDataSource property which provides access to the DataSet dispayed in the database grid control. Read and write access to the property are redirected to the DataLink property.
          </p>
          <p>
            Reading the value for DataSource returns the value stored in the <var>TComponentDataLink</var> instance.
          </p>
          <p>
            Writing the value for DataSource sets the value in the TComponentDataLink instance (when they are not the same). Write access to DataSource also resets the width of columns in the grid by calling <var>RenewColWidths</var>. <var>UpdateActive</var> is called to redraw the grid control after changes to the DataSource and Columns properties.

          Enables or disables optional features or  behaviors in the grid control
        </short>
        <descr>
          <p>
            Options is a TDBGridOptions property that specifies features or behaviors that can be enabled or disabled by values stored in the property. Please note that these options are different than the TGridOption values used in the ancestor class. Options can contain zero (0) or more values from the TDBGridOption enumeration.
          </p>
          <p>
            Options contains the following default values when the control is created:
          </p>
          <ul>
            <li>dgColumnResize</li>
            <li>dgColumnMove</li>
            <li>dgTitles</li>
            <li>dgIndicator</li>
            <li>dgRowLines</li>
            <li>dgColLines</li>
            <li>dgConfirmDelete</li>
            <li>dgCancelOnExit </li>
            <li>dgTabs</li>
            <li>dgEditing</li>
            <li>dgAlwaysShowSelection</li>
          </ul>
          <p>
            See TDBGridOption for more information about values in the enumeration.
          </p>
          <p>
            Changing value(s) in Options causes other aspects of the grid control to be updated to reflect change(s) to the property. ChangedOptions is updated to reflect the enumeration values added or removed in the request. Some enumeration values force other features or behaviors to be disabled. For instance: row selection. Enabling row selection forces the options for editing, always displaying the editor, and row highlighting to be removed from the Options property. Finally, removing multi-selection from the Options property forces the SelectedRows and KeyBookmark properties to be cleared.
          </p>
          <p>
            The TDBGridOption values stored in Options are different than the TGridOption values used in the ancestor class. As a result, SetOptions (the write access specifier) must translate any TDBGridOption values to their TGridOption equivalents and store them in the inherited Options property.  Welcome to the dark world of inheritance in visual controls. It's tedious... just look at the code.

            Please note that AddAutomaticColumns can be performed at run-time only; no actions are performed in the method at design-time.
          </p>
          <p>
            AddAutomaticColumns requires an active dataset to access the Fields that must be added to the grid control. No actions are performed if the datasset in DataLink has not been assigned or marked as Active.
          </p>
          <p>
            AddAutomaticColumns cannot be performed when GridStatus contains either gsRemovingAutoColumns or gsLoadingGrid.  No actions are performed in the method when these values are included in the GridStatus property.
          </p>
          <p>
            AddAutomaticColumns is enabled by including the value dgeAutoColumns in the OptionsExtra property. No actions are performed in the method when the feature has not been included in the OptionsExtra property.
          </p>
          <p>
            AddAutomaticColumns uses DataLink to get the Fields for the dataset, and checks the Columns collection to see if a column already exists for each Field. If the Field is already in the collection, it is skipped to avoid duplicate Fields. Missing Fields are added to Columns using its Add method, and sets the IsAutomaticColumn and Visible properties to True for each. When missing Fields have been added, the ResetColumnsOrder method in Columns is called using the coFieldIndexOrder column ordering option.
          </p>
          <p>
            AddAutomaticColumns updates the GridStatus property prior to adding columns to include the value gsAddingAutoColumns. The value is removed from GridStatus when adding columns has completed. This prevents the TDBGridColumns.Add method from removing automatic columns while the add operation is still active.

            Double-clicking is much more common in a Windows environment than in Unix or
            Linux where single-clicking is the default method for selecting an object.
            However in all environments there could be valid use for a double-click and
            a method should be supplied if appropriate.
