My Grid is like this.
@(Html.Kendo().Grid<GridViewModel>()
.Name("grid-results")
.Sortable()
.Groupable()
.Columns(columns =>
{
columns.Bound(p => p.Id).Hidden().Groupable(false);
columns.Bound(p => p.Total)
.ClientFooterTemplate("Grand Total: #=kendo.toString(sum, 'C4')#")
.FooterHtmlAttributes(new { style = "font-weight:bold; text-align:right;" })
.HtmlAttributes(new { style = "text-align:right" });
columns.Bound(p => p.StatusId ).Title("Resolution Status")
.ClientTemplate("#=StatusName#")
============> .EditorViewData(new { statusId = "#=StatusId #" })
.EditorTemplateName("StatusList"); // file name
columns.Bound(p => p.User);
})
.Pageable(paging => paging
.Info(false)
.Input(true)
.Numeric(false)
.PageSizes(new Int32[] { 5, 10, 20 })
)
.Editable(editable =>
{
editable.Mode(GridEditMode.InCell);
})
.Resizable(configurator => configurator.Columns(true))
.DataSource(dataSource => dataSource
.Ajax()
.ServerOperation(true)
.Read(read =>
{
read.Action("GetResults", "Home").Data("onFilterSelection");
})
.PageSize(10)
.Model(model =>
{
model.Id(p => p.PoId);
model.Field(p => p.Total).Editable(false);
model.Field(p => p.StatusId ).Editable(true);
model.Field(p => p.User).Editable(false);
})
.Aggregates(aggregates =>
{
aggregates.Add(p => p.Total).Sum();
})
)
)
editor template is like
@(Html.Kendo().DropDownList()
.Name(ViewData.TemplateInfo.GetFullHtmlFieldName(string.Empty))
.DataValueField("ListStatusId")
.DataTextField("ListStatusName")
.DataSource(dataSource =>
{
dataSource.Read(read =>
{
read.Action("GetStatusList", "Home", new { statusId = ViewData["statusId"] });
});
})
)
Controller Action:
public JsonResult GetCustomizeResolutionStatusList(string statusId)
{
List<StatusModel> status = new List<StatusModel>();
// code to get list of StatusModel based on statusId
return status ;
}
GridViewModel
public class GridViewModel
{
public int Id { get; set; }
public decimal Total { get; set; }
public short StatusId { get; set; }
public string StatusName { get; set; }
public string User{ get; set; }
}
StatusModel
public class StatusModel
{
public int ListStatusId { get; set; }
public String ListStatusName { get; set; }
}
I tried to use .EditorViewData(new { statusId = "#=StatusId #" }) to pass GridViewModel.StatusId to dropdownlist editor template. But it doesn't work.
I can't use Model.StatusId since the page level view model is different from Grid view model.
Can someone please help me with this?
Thanks.

Please note note that the editor templates are get from the server on Grid initialization (only once) - that why when the EditorTemplate is generated the passed "StatusID" is null. Possible solution to pass the current record ID to the editor is to use external JavaScript function:
EditorTemplate:
@model object@(Html.Kendo().DropDownListFor(m => m) .DataValueField("ListStatusId") .DataTextField("ListStatusName") .DataSource(d => //get the additional data using function in the main view d.Read(r => r.Action("GetStatusList", "Home").Data("getParentID()")) ))getParentID function:
function getParentID() { var row = $(event.srcElement).closest("tr"); var grid = $(event.srcElement).closest("[data-role=grid]").data("kendoGrid"); var dataItem = grid.dataItem(row); //where the OrderID is the model ID return { statusId: dataItem.StatusId }}Vladimir Iliev

As from the provided information is not clear for us what is the exact scenario that you have - could you please open new support thread / forum post and provide the following additional information:
- Grid code
- Grid Model definition
- Custom EditorTemplate that is used

where you declare getParentID ?
In some of grid events?
try to declare in in EditorTemplate, in View with grid - all wrong
My colleague has suggested declaring getParentID() as an external JavaScript function.
Could you try placing the function in a <script> tag above or below the Kendo UI Grid initialization in the Razor view?
<script>function getParentID() { var row = $(event.srcElement).closest("tr"); var grid = $(event.srcElement).closest("[data-role=grid]").data("kendoGrid"); var dataItem = grid.dataItem(row); //where the OrderID is the model ID return { statusId: dataItem.StatusId }}</script>@(Html.Kendo().Grid<GridViewModel>() <!–– grid declaration here ––>)Let me know how you get on.

Thank you for noting that the event srcElement is non-standard.
Event.target should be the preferred option indeed:

For some reason grid.dataItem(row) in undefined in make case
<script>
function getMeterId() {
var row = $(event.target).closest("tr");
var grid = $(event.target).closest("[data-role=grid]").data("kendoGrid");
var dataItem = grid.dataItem(row);
return { meterId: dataItem.MeterId }
}
</script>
Could you console.log(row) and console.log(grid)?
To be able to help you with this, could you please provide more information - sample code for the templates, grid and data source configurations and possibly a dummy dataItem so I can review the project setup locally and make concrete suggestions?

Hi,
From an ongoing support ticket I thought I would share some code: This gets the data item of the currently editing cell (you can call this from your dropdownlist etc)
<script>
function getDataItem() {
var dataItem = $(".k-edit-cell").closest(".k-grid").data("kendoGrid").dataItem($(".k-edit-cell").closest("tr"));
alert(dataItem.myID);
}
</script>
many thks
is my final
function AdditionalData() {
var uid = '#=uid#';
var selector = kendo.format("tr[data-uid='{0}']", uid);
var currentGridElement = $(selector).closest("[data-role=grid]");
var parentRow = currentGridElement.closest(".k-detail-row").prev();
var parentGrid = parentRow.closest("[data-role=grid]").data("kendoGrid");
var parentModel = parentGrid.dataItem(parentRow);
return {
Id: parentModel.id
};
}
var uid is giving me a literal value. I am getting exactly '#=uid#' as string.
Where are you passing this variable. the code below Is not working for me :S.
Can you please help me with this?
Thanks.
Could you please try the following approach instead:
<input type="hidden" name="uid"/><script> function AdditionalData() { var uid = $("[name='uid']").val(); //... }</script>Hope this helps.

Thanks for your earlier answer. it worked!!! :)
Have a great day.
Hello,
Just a quick update, another approach that works well:
function additionalData() {
var gridElement = $(event.currentTarget);
var row = gridElement.find(".k-grid-edit-row");
var grid = gridElement.data("kendoGrid");
var dataItem = grid.dataItem(row);
return { orderId: dataItem.OrderID }
}
@(Html.Kendo().ComboBoxFor(m => m)
.Filter("contains")
.DataTextField("CategoryName")
.DataValueField("CategoryID")
.Placeholder("Select Category...")
.DataSource(source =>
{
source.Ajax()
.Read(r => r.Action("Categories_Read", "Grid").Data("additionalData()"));Regards,

Our thoughts here at Progress are with those affected by the outbreak.
All the possible solutions in here could not solve my problem.
@(Html.Kendo().Grid<WishlistItem>() .Name("gridWishlist") .Columns(columns => { columns.Bound(c => c.Kategorie.Name); // How can I give the Editortemplate this information? columns.Bound(c => c.Count).Width(100).EditorViewData(new { MaxCount = "# =WishlistItem_MaxCount#" }); columns.Command(command => { command.Destroy(); }).Width(130); }) .DataSource(dataSource => dataSource .Ajax() .AutoSync(true) .Events(ev => { ev.Error("gridError"); ev.Sync("calculateKaution"); }) .Model(model => { model.Id(m => m.Id); model.Field(m => m.Kategorie.Name).Editable(false); }) .PageSize(100) // CRUD .Read(r => r.Action("GetKategorieWishlist", "Ausleihe")) .Destroy("DeleteKategorieInWishlist", "Ausleihe") ) .Editable(editable => editable .Mode(GridEditMode.InCell) ) .HtmlAttributes(new { style = KendoManager.Grid_GetHeight(5, false, true) }) .Scrollable(scrollable => scrollable.Virtual(true)) .Sortable())
My EditorTemplate is
@model double?@(Html.Kendo().NumericTextBoxFor(m => m) .Decimals(0) .HtmlAttributes(new { style = "width:100%" }) // Max-Value is coming from Grid-ViewModel. .Max(ViewData["MaxCount"] != null && ViewData["MaxCount"] is int ? (int)ViewData["MaxCount"] : 0) .Min(0))
In my page the user can add existing datasets from combobox into this grid I'll talk about.
The Grid ViewModel is carrying a property with a total count of exemplars of the dataset (WishlistItem_MaxCount). It should be passed into my EditorTemplate, that the NumericTextBox of the Property "Count" has this Max-Value in his settings.
All the solutions in this thread here are talking about comboboxes and dropdownboxes with a defined datasource, but not in my case with a NumericTextBox.
As far I unterstood I can't send the property WishlistItem_MaxCount to my EditorTemplate because the grid is only initialized once at the beginning. So all the dynamically added datasets of my grid can't be applied to this max-amount.
Is there any possible solution to my case?
Hi, Daniel,
The EditorViewData method adds an item inside the ViewData dictionary on the server, it cannot pass a property that is evaluated on the client. If the WishlistItem_MaxCount is not available on the server by means of ViewData or the ViewModel of the page for example, then you could use the Edit() event handler, and change the max of the numeric textbox by getting its instance and calling the max() method:
function onEdit(e){
if(e.container.find("[name='Count']").length){
var numeric = e.container.find("input[name='Count']").data("kendoNumericTextBox");
numeric.max(50);
}
}Kind
