Is it possible to read a DataSource using a Route Name rather than a Controller / Action ? 

Hi folks,

I'm trying to build custom create and edit buttons to navigate to a totally new view, rather than using inline or popups. I've got the edit one to work using a JavaScript function to redirect to the edit view, but can't seem to get the create one to work.

Here's my grid:

@(Html.Kendo().Grid<Project.Models.Organisation>()
.Name("grid")
.HtmlAttributes(new { style = "ScrollHeight: 700px" })
.Columns(columns =>
{
columns.Bound(c => c.Name).Width(80);
columns.Command(command =>
{
command.Custom("Details").Click("showDetails");
}).Width(20);
})
.Sortable()
.Filterable()
.Pageable(x => x.PageSizes(new int[] { 5, 10, 15, 20, 100 }).Refresh(true).ButtonCount(5))
.ToolBar(toolbar => {
toolbar.Custom().Text("Create").HtmlAttributes(new { id = "showCreate" });
})
.DataSource(dataSource => dataSource
.Ajax()
.PageSize(10)
.Events(events => events.Error("error_handler"))
.Model(model =>
{
model.Id(p => p.Id);
model.Field(p => p.Name);
})
.Read(read => read.Action("List", "Organisations"))
)
)

Here's the edit function, which works fine:

function showDetails(e) {
e.preventDefault();
var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
window.location.href = '/Organisations/Details/' + dataItem.Id;
}

And here's the create function, which doesn't appear to do anything:

function showCreate(e) {
e.preventDefault();
window.location.href = '/Organisations/Create/';
}

I've tried a couple of approaches:

1) In ASP.NET examples, you appear to be able to do the following to fire a controller method directly, is this not available in Core?

toolbar.Custom().Text("Create").Action("Create", "Organisations");

2) Another approach that appears possible from research is to use HtmlAttributes, but this appears to do nothing, am I missing something?

toolbar.Custom().Text("Create").HtmlAttributes(new { id = "showCreate" });

I'm pretty new to ASP Core, so any pointers would be gratefully received.

Thanks,
Dave.

I have a dropdown list that has a source where multiple items have to be displayed based on a parameter. I have activated the virtualization and a method of ValueMapper has to be provided.

 

On this javascript function I have to call again using ajax but I have to send also the datasource parameter.

 

Is there a way from the ValueMapper function to get to the dropdownlist? I do not want to know the name of the dropdownlist because this functionality should be used by multiple dropdownlists.

I tried to get to the dropdownlist from the this object but it seems that the function is called in the context of some kind of virtual object and not the dropdownlist

 

Hello.

There is a grid in PartialView:

 

How can I fill this table with data on the client by calling the javascript function without serverside requests?

 

I'm trying to figure out how to handle errors when updating data (inline-editing). I can't bind events.error for the grid, as GridEventBuilder does not include an definition for Error. Whats wrong? I see it in the online demos, but can't use it in VS2017.

Is it possible to show text in the Group Panel at the top of the grid?  i.e., "Drag a column header here for grouping"

Or better yet a way to define the area as some template.

 

I've set up remote validation using asp mvc core and I am using the kendo validator.  I set up some javascript based on the remote validation code I found both in the samples online and some other searches and I added some code to support sending additional parameters. 

I am using the validator to verify that a name is not already in use for a form input.  What I have now actually mostly works, if the name exists then the validator adds the text below the input that the name is already used.  The issue is that when I enter a unique name, the validation message goes away but I still can't submit the form.  Something in the validation is still stopping the submit even though it appears to be validating correctly.

This is what I am using to set up a remote rule for the validator:

 

The controller code that it calls (this works correctly and returns the desired result):

 

The viewmodel where the remote attribute is added:

 

Again, the controller does get called, returns the correct response and I see the correct value come back from the javascript debugger.  After entering a unique name the validation message goes away but the submit is still blocked. When I inpecty the properties of the validator in the debugger it appears there are no errors.

 

Thanks,

Brian

 

 

In demo https://demos.telerik.com/kendo-ui/spreadsheet/custom-editors

cells: [

   { value: "Select item:", bold: true },

   { background: "#fef0cd",

   validation:{

       dataType: "list",

       showButton: true,

       comparerType: "list",

       from: '{ "Foo item 1", "Bar item 2", "Baz item 3" }',

       allowNulls: true,

       type: "reject"}

    }]

I need to choose multi item.

How do i fix it?

Thanks !

When I drop down a dropdown list (DropDownListFor) , it's items are not margined and are truncating to the left.  Can anyone suggest a style to override or a way to set this? 

Thanks
