How to make a field editable in an aspx gridview?

  • 772

I am modifying an ASPX application, I need to add a combo box with a certain data dictionary. basically duplicate the way in which the other columns were defined and create a data source like the ones that were already created, in my opinion, everything is the same... When running the application the new field appears, the combo box has the correct elements , but it doesn't allow me to select an element, almost as if it had the read only property. I can't find what the difference is, what should I do to make it editable? I share image and code. enter image description here

<dx:ASPxGridView ID="ASPxGridView3" runat="server" AutoGenerateColumns="False" DataSourceID="eventos_dtl_com" OnDataBound="ASPxGridView3_DataBound" OnBeforeGetCallbackResult="ASPxGridView3_BeforeGetCallbackResult" SettingsPager-PageSizeItemSettings-ShowAllItem="true" SettingsPager-PageSizeItemSettings-ShowPopupShadow="true" KeyFieldName="serie_int;folio_int;pt;clavePed" OnBatchUpdate="ASPxGridView3_BatchUpdate"  OnRowUpdated="ASPxGridView3_RowUpdated" Theme="Office2010Black" OnHtmlDataCellPrepared="ASPxGridView3_HtmlDataCellPrepared" OnInitNewRow="ASPxGridView3_InitNewRow" OnCellEditorInitialize="ASPxGridView3_CellEditorInitialize">

I show the combo box displayed, and even so it does not allow selecting elements: enter image description here

    If we check the forums of this componentASPxGridView

    GridViewDataComboBoxColumn - Can't select any entries in an ASPxComboBox in inline edit mode

    mentions that the value you put in FieldNamemust be a property that exists in the data source, so the column ClaveUnidadmust exist inDataSourceID="eventos_dtl_com"
