In our UI for ASP.NET Core R3 2020 (2020.3.915) release, the Column menu message of unsticking a column is "null".
This bug will be resolved in our next official release.
In the meantime, as a workaround, manually set the Unstick Column menu message:
.ColumnMenu(c => c.Messages(m => m.Unstick(
"Unstick Column"
)))
Hi,
I'm using Teleik Core components, latest version in mvc application.
I have defined grid in view with name "gridMara"
In javascript i have code:
var gridMara = $("#gridMara").data("kendoGrid");
I checked in console, $("#gridMara") is initialized.
But when i use statement:
var gridMara = $("#gridMara").data("kendoGrid");
the value of gridMara is undefined.
Please help.

Hi all,
Going nuts over this problem. Should be simple, and for other technologies telerik shows solutions, but can not get it to work for razor pages .net core.
What i want is:
I have a grid that opens in a popup when editting. In the editortemplate i have a childgrid showing all possible children that can be added to this record. That is working. However, i want to multiselect in this grid without having my customers to hold down ctrl or use a textbox. Main reason: When using a textbox, you really have to click in the textbox, clicking outsisde of it won't work. So i removed the select column (the checkboxes) and just want people to click somewhere on a row to select it and be able to click on another row without the fiorst one loosing it's selected status. The only hook i can find is the onchange event. This indeed allows me to catch the slection process. However, the previously selected items are not available any more, so i oose them.
Anyone an idea how to do this quite simple trick?

Hello,
create/update posts an empty model to the controller.
It was working in a very old asp.net mvc project. I setup a new asp.net core project. I spent some hours to fix this, but no luck.
Reading the data source is ok and the data is shown in column 'valuestream'. At the moment for 'Agenda' two values are shown, editable with a mutiselect.
Controller:
public ActionResult ManagerQuestionnaireCreate([DataSourceRequest] DataSourceRequest request, QuestionnaireViewModel rs)
{
....
return Json(new[] { rs }.ToDataSourceResult(request, ModelState));
}
Model:
View:
Prior to the most recent version we could use reflection to get the grid name in this method.
We have changed it to pass the grid name, but was wondering if there is a programmatic way of getting the grid name without passing it
public static GridToolBarCommandFactory<T> SuperSearch<T>(this GridToolBarCommandFactory<T> builder, string gridName, string title = "Super Search...") where T : class
I have a grid with custom editors and they are bound to the grid as such.
columns.Bound(x => x.Parent).EditorTemplateName("ParentEditor").ClientTemplate("#= Parent === undefined || Parent === null ? '' : parentTemplate(Parent)#");
columns.Bound(x => x.Child).EditorTemplateName("ChildEditor").ClientTemplate("#= Child === undefined || Child === null ? '' : childTemplate(Child)#");
The two editor templates look like this:
@model List<ParentViewModel>
@(Html.Kendo()
.MultiSelectFor(m => m)
.DataTextField("Name")
.DataValueField("Id")
.Placeholder("Select one or more parents")
.AutoBind(true)
.TagMode(MultiSelectTagMode.Multiple)
.DataSource(source =>
{
source
.Read(read =>
{
read.Action("GetParent", "Lookup");
});
})
.Events(events => events.Change("onParentChange"))
)
@model List<ChildViewModel>
@(Html.Kendo()
.MultiSelectFor(m => m)
.DataTextField("Name")
.DataValueField("Id")
.Placeholder("Select one or more children")
.AutoBind(true)
.TagMode(MultiSelectTagMode.Multiple)
.DataSource(source =>
{
source
.Read(read =>
{
read.Action("GetChild", "Lookup").Data("getCurrentParents");
})
;
})
)
The UI is properly populating when the grid loads and looks like this:
Coumn Parent|Column Child
A |A1
B |B1, B2
When the user edits the row and removes item B from Column Parent, this code is invoked (which I got from Kendo UI Snippet | Kendo UI Dojo)
function onParentChange(e) {
var selectedonParentChange = this.value();
let dataItems = e.sender.dataItems();
var multiSelect = $("#Child").data("kendoMultiSelect");
var value = multiSelect.value();
multiSelect.dataSource.filter(getFilterObj(dataItems));
multiSelect.dataSource.filter({}); // Adding or removing has no effect
multiSelect.refresh();
multiSelect.value(value);
console.log("Second value: " + multiSelect.value());
var dataSource = multiSelect.dataSource;
dataSource.read();
}
function getFilterObj(dataItems){
let filtObj = {
logic: "or",
filters: [],
};
if(dataItems.length > 0){
for (var i = 0; i < dataItems.length; i++) {
filtObj.filters.push({
field: "ParentId",
operator: "eq",
value: dataItems[i].Id
});
}
} else {
filtObj.filters.push({
field: "ParentId",
operator: "eq",
value: ""
});
}
return filtObj;
}
After the code runs, the UI looks like this:
Coumn Parent|Column Child
A |A1
So far so good. The problem is that when the user hits save this ends up on the Network in the form data:
Parent[0].Id: ParentIdA
Parent[0].Name: A
Child[0].Id: ChildId1
Child[0].Name: A1
Child[0].ParentId: ParentIdA
Child[1].Id: ChildId2
Child[1].Name: B1
Child[1].ParentId: ParentIdB
Child[2].Id: ChildId3
Child[2].Name: B2
Child[2].ParentId: ParentIdB
I'm currently redesigning the filter menus in our MVC ASP.NET Core project. As of now, they all have the default menu:
I would like to customise the menus according to the columns' data types - have date range pickers for dates, a slider from min to max value for numbers, etc. The main point is to make the process simpler - so the users only need to input a few characters/choose a date/slide to the right number, instead of filling out this complicated configuration.
Some of such components are provided by kendo (e.g. DateRangePicker), others aren't (e.g. the above-mentioned slider; at least I didn't find anything like it), but could be implemented with a custom function. Either way, I can't seem to be able to override the default filter menu.
The only promising suggesstion on how to achieve something like this that I found was:
grid.Columns(c => c.Bound(item.Name)
.Filterable(ftb => ftb.UI("datePickerFilter"))
function datePickerFilter(element) {
element.kendoDateRangePicker({
messages: {
startLabel: "Check-In",
endLabel: "Check-Out"
},
format: "MM/dd/yyyy"
});
}
