Initializing New Rows

Feb 06, 2023

The GridView extension allows you to define the default field values displayed within the built-in edit form for the newly added records.

To initialize row values in code, define the initial values in the ASPxDataInitNewRowEventArgs.NewValues dictionary within a delegate method, and assign this delegate method to the GridViewSettings.InitNewRow property.

csharp

@Html.DevExpress().GridView(settings => {
    settings.Name = "GridView";

    // ...
    settings.KeyFieldName = "CustomerID";
    settings.Columns.Add("CompanyName");
    settings.Columns.Add("ContactName");
    settings.Columns.Add("ContactTitle");
    settings.Columns.Add("Phone");
    // Process the initialization of new rows.
    settings.InitNewRow = (s, e) => {
        e.NewValues["Phone"] = "(5) 555-12-34";
        e.NewValues["ContactTitle"] = "Owner";
    };
}).Bind(Model).GetHtml()
