I want to be able to push the record count from my Kendo grid after read (refresh).
Here is my Kendo Grid:
@(Html.Kendo().Grid(Model)
.Name("SearchWindowGrid")
.Columns(columns =>
{
columns.Bound(p => p.SYSTEM_ITEMS_SEGMENT1).Hidden();
})
.ClientRowTemplate(
"<tr>" +
"<td>" +
"<span><b>#: SYSTEM_ITEMS_SEGMENT1#</b></span> <br/>" +
"<span>#: DESCRIPTION# </span>" +
"</td>" +
"</tr>"
)
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("PopulateSearchWindow", "Item").Data("additionalSearchWindowInfo"))
.Events(ev => ev.Error("onErrorSearchWindow"))
)
.Selectable(s => s.Enabled(true).Mode(GridSelectionMode.Single).Type(GridSelectionType.Row))
.Scrollable(s => s.Enabled(true).Height(450))
)
My Controller action:
public ActionResult PopulateSearchWindow([DataSourceRequest] DataSourceRequest request, string option, string searchText, string searchDesc)
{
try
{
var derps= _idg.SearchItems(searchText, searchDesc, _adg.OrganizationCode).ToList();
return Json(derps.ToDataSourceResult(request, ModelState));
}
catch (Exception e)
{
ModelState.AddModelError("ExceptionErrors", e.Message);
return Json(new List<Derp>().ToDataSourceResult(request, ModelState));
}
}
Here is my function that forces data refresh:
function refreshData(){
$("#SearchWindowGrid").data("kendoGrid").dataSource.read();
//TODO: get the total count and push to #countElement
var count = $("#SearchWindowGrid").data("kendoGrid").length; //not sure what to do here
$("#countElement").val(count);
}
Where I put my TODO in the jQuery function I want to be able to get the number of rows and push that number into a specific elemnt on my page.
According to the API Reference here
the dataSource has a total() function. So you should be able to do the following, in theory:
function refreshData(){
var grid = $("#SearchWindowGrid").data("kendoGrid");
grid.dataSource.read();
var count = grid.dataSource.total();
$("#countElement").val(count);
}
