1. Introducing

Textual Columns in NextGrid and NextDBGrid such as TNxTextColumn, TNxNumberColumn own a Editor object, which represent Inplace-Editor for this column.

By using Editor object we may additionally customize Edit, SpinEdit, ComboBox... before cell enter into edit state.

2. First Samples

Since Editor object is property of column, we may simply access to it:

NextGrid1.Columns[4].Editor...

NextGrid1->Columns[4]->Editor...

Events such as OnBeforeEdit or OnApplyEditText are ideal for fine tuning your Editor.

3. Type Casting

Editor object is created from TNxCustomEdit class which give a possibility for using other TNxCustomEdit descendants as TNxComboBox, TNxSpinEdit...

Accessing TNxCustomEdit properties is simple by using next code:

NextGrid1.Columns[0].Color := clRed;

NextGrid1->Columns->Item[0]->Color := clRed;

For accessing to class specific properties and methods typecasting must be used:

TNxSpinEdit(NextGrid1.Columns[0].Editor).Max := 200;

((TNxSpinEdit*)(NextGrid1->Columns->Item[0]->Editor))->Max = 200;

4. InplaceEdit property

Each column in NextGrid and NextDBGrid include a InplaceEdit property which may be attached to the edit control from Next Editor component palette such as TNxEdit, TNxSpinEdit...

Edit control may be customized and when grid enters into edit state, edit will be used a cell Inplace Editor.

BorderStyle property of edit control in most cases need to be set to bsNone to exclude double border when cell is being edited.
