Example

To execute the example, add on the form the CtrlGroupConditions component named CtrlGroupConditions1.

Add a link to the Forms system assembly.

The example is a handler of the OnCreate event for the form.

Sub TESTFormOnCreate(Sender: Object; Args: IEventArgs);
Var
    Columns: IListViewColumns;
    Attr, Condition, Value: IListViewColumn;
    AttrEditBox, AttrEditBox2, AttrEditBox3, AttrEditBox4: IEditBox;

    Date: IDateTimePicker;
    ValueEdit: IIntegerEdit;

    // Determine columns

    Attr.Caption := "Attribute";

    Value := Columns.Add;
    Value.Caption := "Value";

    // Add the first element
    CtrlGroupConditions1.AddRow(ConditionOperatorType.Or_);
    // Add a visual component for the Attribute column
    AttrEditBox := New EditBox.Create;
    AttrEditBox.Text := "DATE";
    CtrlGroupConditions1.InsertControl(AttrEditBox, 2, 0);
    // Add a visual component for the Condition column

    AttrEditBox2 := New EditBox.Create;
    AttrEditBox2.Text := "NAME";
    CtrlGroupConditions1.InsertControl(AttrEditBox2, 2, 1);
    // Add a visual component for the Condition column
    List2 := New TreeCombo.Create;
    List2.Nodes.Add(Null, "Equal").Selected := True;
    List2.Nodes.Add(Null, "Not equal");
    List2.Nodes.Add(Null, "Less");
    List2.Nodes.Add(Null, "Greater");
    List2.Nodes.Add(Null, "Less or equal");
    List2.Nodes.Add(Null, "Greater or equal");
    List2.SelectionMode := SelectionModeType.SingleSelect;
    CtrlGroupConditions1.InsertControl(List2, 3, 1);
    // Add a visual component for the Value column
    AttrEditBox3 := New EditBox.Create;
    AttrEditBox3.Text := "Report";
    CtrlGroupConditions1.InsertControl(AttrEditBox3, 4, 1);

    // Add the third element
    CtrlGroupConditions1.AddRow(ConditionOperatorType.Or_);
    // Add a visual component for the Attribute column
    AttrEditBox4 := New EditBox.Create;
    AttrEditBox4.Text := "KEY";
    CtrlGroupConditions1.InsertControl(AttrEditBox4, 2, 2);
    // Add a visual component for the Condition column
    List3 := New TreeCombo.Create;
    List3.Nodes.Add(Null, "Equal").Selected := True;
    List3.Nodes.Add(Null, "Not equal");
    List3.Nodes.Add(Null, "Less");
    List3.Nodes.Add(Null, "Greater");
    List3.Nodes.Add(Null, "Less or equal");
    List3.Nodes.Add(Null, "Greater or equal");
    List3.SelectionMode := SelectionModeType.SingleSelect;
    CtrlGroupConditions1.InsertControl(List3, 3, 2);
    // Add a visual component for the Value column
    ValueEdit := New IntegerEdit.Create;
    ValueEdit.Value := 12345;
    CtrlGroupConditions1.InsertControl(ValueEdit, 4, 2);
End Sub TESTFormOnCreate;

After executing the example, columns are determined and three elements with visual components are added in the CtrlGroupConditions component:
