Creating columns
4. Creating columns
The GenerateColumns method creates columns in a grid control, and this presents data from the TPriceList object. It also assigns every column a unique value via the TcxGridColumn.DataBinding.Data property used to identify it in the GetValue and GetInfoForCompare methods.
GenerateColumns sets the type for values in columns via the TcxGridColumn.DataBinding. ValueTypeClass property.
procedure GenerateColumns(AGridTableView: TcxGridTableView);
begin
with AGridTableView do
begin
OptionsSelection.HideFocusRect := False;
OptionsSelection.MultiSelect := True;
ClearItems;
with CreateColumn as TcxGridColumn do
begin
Caption := 'Description';
DataBinding.ValueTypeClass := TcxStringValueType;
DataBinding.Data := Pointer(DescriptionID);
Width := 100;
end;
with CreateColumn as TcxGridColumn do
begin
Caption := 'OnHand';
DataBinding.ValueTypeClass := TcxIntegerValueType;
DataBinding.Data := Pointer(OnHandID);
Width := 100;
end;
with CreateColumn as TcxGridColumn do
begin
Caption := 'Price';
DataBinding.ValueTypeClass := TcxCurrencyValueType;
DataBinding.Data := Pointer(PriceID);
Width := 100;
end;
end;
end;
