Multi filter with null values - they are not visible

Hi,

In my grid there are cells where we can accept having null values, e.g. property can exist without owner. I would like to filter owner column in multifilter by having null. Right now, empty (null) values are not visible in multi filter menu, only existing owners are displayed. We hacked the problem by switching from null values to empty strings "", and they are visible in menu. But I'm feeling extremely awful for doing such hacks in my code.

I checked that it's made like that because in FilterMultiCheck _init function you got such line:

FilterMultiCheck

_init: function () {

...

this.checkSource.data(distinct(this.dataSource.data(), this.field));

...

And the distinct function looks like that:

function distinct(items, field) {

...

if (text !== undefined && text !== null && !seen.hasOwnProperty(text)) {

result.push(item);

seen[text] = true;

}

...

You see, that null and undefined values are omited and they are not the part of the results. Unfortunately, removing the null & undefined conditionals don't work - null is showed in menu but you cannot filter by it.

Will you be able to do something with it in the future? Right now i can workaround it, but it's really nasty to replace nulls with empty strings :)

How to pass string as a argument in a Template

How can I pass a string with single quote in a Kendo grid template -

In the below code I have a function confirmDelete which expects a string argument, in the example I am passing id (encrypted string) but when I add the single quote around it the HTML rendering fails. If I pass just id with no quotes AngularJs throws a error.

This may not be the right forum but I have not got response from the Kendo Lab, i will appreciate your help.

k-columns='[
{ "field": "firstName", sortable:true, "title": "First Name"},
{ "field": "lastName", sortable:false,"title": "Last Name"},
{ "field": "middleName", sortable:true,"title": "Middle Name"},
{ "field": "id", sortable:true,"title": "Id"},
{ "template": "<a href=\"Constituent/Detail/#: id#\">Edit</a><a href=\"\" ng-click=\"confirmDelete('\"+id+\"')\">Delete</a>", "title": "Actions" }]'

Kendo MVVM Template - Not binding Correctly

Hi,

I am trying to bind kendo template with MVVM but unfortunately facing some weird issue. My JSON looks correct but the template is binding the data incorrectly. What's interesting is if I comment either Dropdown or Span, the other control works perfectly. I tried assigning a unique Ids to control but it's not helping. Could you please check below fiddle?

Globally Override Default Properties

Hi Guys,

When using the Grid widget I can globally override a property, for example columnMenu as follows

   kendo.ui.Grid.fn.options.columnMenu = {
        columns: true
   };

but I am unable to find any examples in how to override the default dataSource properties.

What I'm trying to achieve is to always default the schema section with the following values

   schema: {
        data: "data",
          errors: "error",
          total: "total",
     },

to save having to duplicate them on every dataSource instance.

Is this at all possible ?

Regards
Alan

Grid group footer names

We have an Aggregrate Grid that is grouping on two fields. The Grid handles this great, but a display problem is causing some user confusion.

See the attached screenshot. We are grouping on "Year" and "Make". We wanted to show "Total:" on the group footer row so users know what the row is for. So in the "Vehicle" column, we set the groupFooterTemplate to "Total:". You can see it appearing in the screenshot just fine.

So now for the Make groups and the Year groups, there appears a "Total:" in the aggregate footer row. But as you can see in the screenshot, the last Make group footer row (circled in red) sits right on top of the Year group footer row (circled in blue), and they both show "Total:" on that row, but it looks confusing. Is there any possible way to display "Make Total:" and "Year Total:" on those rows? Or even better would be "Mazda Total:" and "2015 Total:". In other words, instead of just specifying this column:

{ field: "Vehicle", title: "Vehicle", footerTemplate: "Grand Totals:", groupFooterTemplate: "Total:" }

Is there a way to use the group name in the groupFooterTemplate?

{ field: "Vehicle", title: "Vehicle", footerTemplate: "Grand Totals:", groupFooterTemplate: this.groupName + " Total:" }
