Use Wizard like Dialog Editing

Wizard helps you create intuitive step-by-step forms to fill. You can achieve the wizard like editing by using the dialog template feature. It support your own editing template by defining Mode of EditSettings as Dialog and Template as SCRIPT element ID or HTML string which holds the template.

The following example demonstrate the wizard like editing in the grid with the obtrusive Validation.

razor
dialog.cs
@Html.EJS().Grid("DialogTemplateEdit").DataSource((IEnumerable<object>)ViewBag.DataSource).ActionComplete("actionComplete").Columns(col =>
{
   col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Width("120").ValidationRules(new { required = true }).TextAlign(Syncfusion.EJ2.Grids.TextAlign.Right).Add();
   col.Field("CustomerID").HeaderText("Customer Name").Width("150").ValidationRules(new { required = true, minLength = 3 }).Add();
   col.Field("ShipCountry").HeaderText("Ship Country").EditType("dropdownedit").Width("150").Add();

}).AllowPaging().PageSettings(page => page.PageCount(2)).EditSettings(edit => { edit.AllowAdding(true).AllowEditing(true).AllowDeleting(true).Mode(Syncfusion.EJ2.Grids.EditMode.Dialog).Template("#dialogtemplate"); }).Toolbar(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" }).Render()
