Hello,

Iam using Grid with CRUDURL and loading Data with DataManager.
How to realize a dynamic search over all Columns?

Thanks

If I use this as Datasource, searching is working:
.Datasource((IEnumerable<Mitarbeiter>)ViewBag.datasource2)

But I also want to Edit the Grid, so i changed it to:
.Datasource(ds=>ds.URL("Mitarbeiter/LoadData").CrudURL("Mitarbeiter/CrudUpdate").Adaptor(AdaptorType.UrlAdaptor)).AllowPaging()

Now i can not really search, because i have to pass dynamicly the search Columns to Entity Framework, what is not working.

Can I combine the Datasource Expression??? Like this:
.Datasource(ds=>ds.URL("Mitarbeiter/LoadData").CrudURL("Mitarbeiter/CrudUpdate").Adaptor(AdaptorType.UrlAdaptor)).AllowPaging().Datasource((IEnumerable<Mitarbeiter>)ViewBag.datasource2)

Thanks

Hi Arthur, 

Thank you for contacting Syncfusion support. 

While using UrlAdaptor, we need to handle grid operation(filtering/searching/sorting) in server side. Please refer to the below knowledgebase document, help document, code example and sample. 


GridFeatures.cshtml 
@(Html.EJ().Grid<object>("FlatGrid") 
            .Datasource(ds => ds.URL("/Grid/DataSource").CrudURL("/Grid/CrudUpdate").Adaptor(AdaptorType.UrlAdaptor)) 
        })) 
GridController.cs 
public ActionResult DataSource(DataManager dm) 
        { 
             
 
           if (dm.Search != null && dm.Search.Count > 0) //searching 
            { 
                result.result = operation.PerformSearching(DataSource, dm.Search); 
            } 
            .. 
 
           return Json(result, JsonRequestBehavior.AllowGet); 
        } 


Regards, 

Jayaprakash K.
