Assigning Editors to Columns

Expanded Assigning Editors to Columns

The most common way of using in-place editors is by assigning them to columns. This is a typical scenario, since columns are usually presented as a number of fields that contain values of the same type. You can assign different editors to columns with respect to their type. An in-place editor can be assigned to a column as follows:

  • Create a corresponding repository item object, representing the required in-place editor.
  • Add the repository item to the internal or external repository.
  • Assign it to the TreeListColumn.ColumnEdit property.

The image below shows an example of assigning various editors to Tree List columns.

At design time, the TreeListColumn.ColumnEdit property provides a dropdown window that enables quick in-place editor assignment. The dropdown allows you to create a new in-place editor (repository item), or choose from among existing in-place editors. If you create a new in-place editor at design time, it's automatically added to the Tree List's internal repository.

For more information about repositories, see the Inplace Editors document.

By default, the editor assigned to a cell via the TreeListColumn.ColumnEdit property or TreeList.CustomNodeCellEdit event will also be used for editing the cell's contents. If you want to use a different editor for in-place editing, handle the TreeList.CustomNodeCellEditForEditing event.

Expanded Example

The following example demonstrates how to create and adjust a new in-place editor (ComboBoxEdit). The editor is bound to the "Location" column using the TreeListColumn.ColumnEdit property.

The screenshot below demonstrates the result of the code's execution
