[Solved] Webservice Databinding with Arguments

[Shawn]

I see that when using Ajax databinding, you are able to send additional arguments to the service, however i do not see a way to send an argument to a websevice.

Is there a way to do this?  If not, this is a big time deal breaker!!

Here is my code for the grid and the webservice  I need to be able to pass the stateid to the webservice (its currently hard coded, but would need to be a parameter)

<%= Html.Telerik().Grid<BcMemProxyStub>()

.Name("Members")

.HtmlAttributes( new {style = "width:805px;"})

.ToolBar(commands => commands.Custom().Url("Security.mvc/MemberImport").Text("Batch Import").HtmlAttributes(new { @class = "popup" }))

.Columns(columns =>

{

columns.Bound(m => m.MemID).Width(85)

.ClientTemplate("<div><a href='Security.mvc/Member/<#=MemID#>' class='popup'><#= MemID #></a></div>");

columns.Bound(m => m.Login).Width(150);

columns.Bound(m => m.Fname).Width(150);

columns.Bound(m => m.Lname).Width(150);

columns.Bound(m => m.Memail).Width(270);

columns.Bound(m => m.MemID).Filterable(false).Title(" ").Width(10)

.ClientTemplate("<div><a href='/SiteAdmin/Models/SecurityService.svc/MemberDelete?ID=<#=MemID#>' class='action'><img border=0 src=\"/siteadmin/content/images/cancel.png\"/></a></div>");

})

.DataBinding(dataBinding => dataBinding.WebService().Select("~/Models/SecurityService.svc/Members"))

.Sortable()

.Pageable(paging => paging.PageSize(20))

.Filterable()

.ClientEvents(events => events

.OnDataBound("WireActionLinks")

)

%>

[OperationContract]
        public GridModel Members(GridState state)
        {
            var bcms = new BcMemCollection();

            bcms.LoadByState(52);

            return new BcMemCollectionProxyStub(bcms).Collection.ToGrid(state);
        }

Hello Shawn,

Indeed there is no easy way to supply parameters to web services now. I am attaching a new build which would make things easier. You need to use the OnDataBinding event and supply the required argument:

.ClientEvents(events => events.OnDataBinding("onDataBinding"))
%>

<script type="text/javascript">
    function onDataBinding(e) {
        e.data = { id: 52 };
    }
</script>

I got around this a slightly different way:

.DataBinding(dataBinding => dataBinding.WebService().Select("~/Models/SecurityService.svc/Members?ID=" + Html.State().StateABBR))

I added it as a query parameter, which WCF doesnt seem to mind.  I am able to grab the value in the webservice this way:

var ID = HttpContext.Current.Request.QueryString["ID"];

That being said, i think i like this solution better, thanks for the newer build!
