public RepositoryItem ColumnEdit { get; set; }

Property Value

Type Default Description
RepositoryItem null

A RepositoryItem descendant.

Data Grid - Column Edit Smart Tag

If you set up the ColumnEdit property in code, do not forget to add any new RepositoryItems you create to the Data Grid’s EditorContainer.RepositoryItems collection. The following code illustrates how to assign a new ProgressBarControl in-place editor for the “Relevance” column. The editor’s KeyPress event is handled to allow users to tap\hold “+” and “-“ keys to edit cell values.

using DevExpress.XtraGrid.Views.Grid;
using DevExpress.XtraEditors.Repository;

//create a repository item 
RepositoryItemProgressBar ieProgress = new RepositoryItemProgressBar();
ieProgress.KeyPress += IeProgress_KeyPress;

//assign repository item 
colRelevance.ColumnEdit = ieProgress;

//handle + and - keys press 
private void IeProgress_KeyPress(object sender, KeyPressEventArgs e) {
    int i = 0;
    if (gridView1.ActiveEditor == null) return;
    i = (int)gridView1.ActiveEditor.EditValue;
    if (e.KeyChar == '+') {
        if (i < 100)
            gridView1.ActiveEditor.EditValue = i + 1;
    if (e.KeyChar == '-') {
        if (i > 0)
            gridView1.ActiveEditor.EditValue = i - 1;

Along with the ColumnEdit property there are other ways to provide in-place editors to data cells.




Identical to the ColumnEdit property but accepts editor names instead.


Allows you to assign in-place editors to individual cells rather to the entire Grid column.


Provides in-place editors that cells use only when a user starts editing cell values.


If you did not assign a custom editor to a column, Data Grid automatically creates in-place editors for columns. The actual editor type depends on the bound field’s data type (for instance, a column bound to a DateTime data displays the DateEdit editor). The RealColumnEdit property allows you to retrieve this default column editor.


This example binds a GridControl to a collection of custom Record objects and demonstrates the following features:

  • Assigning an inplace editor (combo box) to a column

  • Specifying a column’s display name and data format by applying DataAnnotation attributes to Record class properties

  • Two ways of changing cell values - at the data source and grid level.

  • Highlighting cell values that meet a condition
