[Solved] Server-side Row-based Action Links Inside a Template

[Merritt]

I often need to create my own custom commands for a given grid outside the scope of the built-in CRUD commands. For instance, I need to have a disable button for each row in a grid, and I am sort of stumped about how to maintain the grid state when doing so:

<% Html.Telerik().Grid(Model.Clients)
        .Name("Grid")
        .DataKeys(k => k.Add(o => o.Id))
        .PrefixUrlParameters(false)
        .Editable( e => e.Mode(GridEditMode.PopUp))
        .Sortable()
        .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.ImageAndText))
        .DataBinding( b => b.Server()
            .Select("Index", "Client")
            .Update("Update", "Client")
           .Insert("Insert", "Client")
        )
        .Columns(columns =>
        {
            columns.Bound(o => o.Id).Visible(false).ReadOnly(true);
            columns.Bound(o => o.IP).Width(150);
            columns.Bound(o => o.TerminalNumber).Visible(true).Title("Terminal").Width(50);
            columns.Bound(o => o.Description).Width(300);
            columns.Bound(o => o.Disabled).Width(50);
            columns.Bound(o => o.Terminals).Visible(false).Sortable(false);
            columns.Template(c =>{
            %>
                <% using (Html.BeginForm("Disable", "Client", new { id = c.Id }, FormMethod.Post, new { @class = "t-grid-actions" }))
                { %>
                    <button class="t-grid-action t-button t-state-default" type="submit">Disable</button>
                <% } %>
            <% }).Width(50);
            columns.Command(s =>
            {
                s.Edit();
            }).Width(100);
        }).Render();
    %>

The problem with that template is it loses any order-by or sort-by information that I might have associated with the grid. I have noticed this information is accessible from the Edit command, and I see that it is appended in the query string  to the action links created (for Editing).

[HttpPost]
public ActionResult Update(EditableClientGridItem viewModel, GridCommand command, string mode, int? id)

The GridCommand command parameter contains all the information I need.

Hi Merritt,

In order to achieve the requested functionality you should manually persist the grid's route values. I have attached a small sample which demonstrates how to implement such approach.
