How to: Assign Different Column Editors for Different Rows

The following example shows how to handle the GridView.CustomRowCellEdit event to assign ComboBoxEdit, SpinEdit and CheckEdit editors to cells, depending on the FieldName column value. It is assumed that the repository items corresponding to these editors are already in a repository.

The screenshots below show the grid's appearance before and after code execution. The ColumnView.ShowButtonMode property is set to ShowButtonModeEnum.ShowAlways for demonstration purposes.

C#: using DevExpress.XtraGrid.Views.Grid;   private void gridView1_CustomRowCellEdit(object sender, CustomRowCellEditEventArgs e) {    if (e.Column.FieldName == "FieldName") return;    GridView gv = sender as GridView;    string fieldName = gv.GetRowCellValue(e.RowHandle, gv.Columns["FieldName"]).ToString();    switch (fieldName) {       case "Population":          e.RepositoryItem = repositoryItemSpinEdit1;          break;       case "Country":          e.RepositoryItem = repositoryItemComboBox1;          break;       case "Capital":          e.RepositoryItem = repositoryItemCheckEdit1;          break;    }           }

VB: Imports DevExpress.XtraGrid.Views.Grid   Private Sub GridView1_CustomRowCellEdit(ByVal sender As Object, _   ByVal e As CustomRowCellEditEventArgs) _   Handles GridView1.CustomRowCellEdit    If e.Column.FieldName = "FieldName" Then Return    Dim Gv As GridView = sender    Dim FieldName As String = Gv.GetRowCellValue(e.RowHandle, _      gv.Columns("FieldName")).ToString()    Select Case (FieldName)       Case "Population"          e.RepositoryItem = repositoryItemSpinEdit1       Case "Country"          e.RepositoryItem = repositoryItemComboBox1       Case "Capital"          e.RepositoryItem = repositoryItemCheckEdit1    End Select End Sub
