[Solved] Parameter for generic DataBinding Actions

[Frank Michael]

I can't figure out how I can provide the necessary id parameter for the .Delete<SprintController>(sc=>sc.AjaxGridDelete(id)) and .Update method.
I can't just leave it blank like with .Delete("AjaxGridDelete","Sprint") because it is syntax checked.

Html.Telerik().Grid<RenderSprint>()
        .BindTo(Model)
        .Name("SprintGrid")
        .Localizable("de-DE") //ToDo Culture allgemein ersetzen
        // .Selectable() // - nett aber nutzlos.
        .ToolBar(tb => {
            tb.Insert();
            tb.Custom().Action<SprintController>(sc => sc.Aggregate()).Text("Aggregate"); // ToDo hier muss ich Ajax machen.
        })
        .DataBinding(b => b.Ajax()
            .Select<SprintController>(sc => sc.AjaxGridSelect())
            //ToDo .Delete<SprintController>(sc => sc.AjaxGridDelete())
            .Delete("AjaxGridDelete", "Sprint")
            .Insert<SprintController>(sc => sc.AjaxGridInsert())
            // ToDo .Update<SprintController>(sc => sc.AjaxGridUpdate()))
            .Update("AjaxGridUpdate", "Sprint"))

Hello Frank Michael ,

You just need to pass the required value to the action method:

.Select<SprintController>(sc => sc.AjaxGridSelect(5))

We need more information about your scenario in order to provide a complete solution.

It is clear that I need to pass a parameter.
But where should I get it from?
It is the key of the row.
I declared

.DataKeys(k => k.Add(s => s.RowKey))

So I should expect that it is possible somehow to access this key, but I do not know how.

A workaround could be to add an invisible column with the key, But then I do not know how I could access the cell content as well.

Hello Frank Michael ,

You cannot access the underlying object when defining the action methods. Since the keys are automatically added you can use a dummy value for the parameter in order to satisfy the compiler e.g.:

.Select<SprintController>(sc => sc.AjaxGridSelect(5))

The other option is not to use the generic methods but the string based ones.
