Hi, I have a filter on the left side of my web and a grid with the result on the left side. By default that grid is empty, but when I submit the filter form the result should be shown in this grid. I am using kendo spa and mvvm so my observable (model) is something like this:


where getAgentOnlyFound get the data in json format from the server, so... 


and my html:


the real example is pretty much large but I just put here the important part. My problem is: this example works in random way. Sometime it works and sometime doesn't and I do not receive any javascript errors from my browser.

Any idea ??

Thanks in advance...

Hi,

It seems to me TreeView element is not working correctly for such scenario.

1. Read action controller sets checked attribute to true if corresponding item can be found in specific table or has an ancestor item found in that table.
2. There is a TreeView element with checkboxes enabled, checkChildren and loadOnDemand are turned on.

Workflow: user unchecks some item, which has children and was checked before, but not expanded. Then user expands the node, and all checks return back, because they are assigned to subitems based on the status in table without considering the fact that some change has happened on front-end already.

Similarly, if neither an item, nor any of its sub-items was checked, then item gets checked, then expanded - all checks will disappear.

I do understand that this is a complex issue, but please advise what options do I have now, except of advising users not to expand after checking or unchecking, or to expand before checking or unchecking?

Please note that if I do loadOnDemand = true, it will take terrible time to apply all checks accordingly (the number of treeview items is hundreds already and will grow).

Thank you.

Hi Team,

We have a requirement where-in we have to visually represent a real-time series data (time against the value). 
We had found your kendo chart demo interesting provided under your web-site

DATA VISUALIZATION -> Chart API -> Benchmark

In the Benchmark chart, the chart is moving. Aloing with it we like to add navigator. This navigator should try to persist
start range data and end range data somewhere locally.

We like to have backward and forward playback controls to this Benchmark chart to view the trend back and forth.
Currently play and pause functions are available in the demo.

We also want crosshair to be available over the catergory axis by default all the time during running of the trend chart
instead on mouse hover.

Please help us out.

Thanks,
Siva

Hi,

When a form loads we want to highlight which fields are required fields by changing the colour of the label.  If you look at the attached image SoureRequiredAuthorNotRequired.PNG you can see the Source field is highlighted in red as it is a required field.  When a value is entered for the Source the red highlighting disappears.

To do this we have used:


We have now added in a Kendo date picker and hoped this would work in the same way:


Unfortulately this does not work.  It seems that to validate a kendo date picker you have to use the kendo validator.  Is that correct?

Assuming that is correct, we added the following code:


to use the kendo validator.  Looking at the documentation you have a validateInput function which validates just one field:

http://docs.telerik.com/kendo-ui/api/javascript/ui/validator#methods-validateInput

We then tried:


Which did not work.  validateInput only seems to work if it used as part of a button click.  Is this correct?

How can I get this to work so that the red highlighting appears when nothing has been entered and disappears when a value has been entered (without the user clicking on a save button etc)?

Many thanks

Is there a way to change the relative position of a donut chart's tooltip?

If my chart is close to the edge of my RadDock, the tooltip is chopped off or I get an unsightly scrollbar.  I am attaching a screenshot and pasting an example of the undesired behavior:

Thank you,

Hello.  I'm trying to talk to a Rails app using REST & json. I'm having problem passing custom group parameter. I tried various different hacks but nothing seems to work. Here my code ( I made it as simple as possible to make sure it run and I'm still getting an error)


The service I'm passing params to requires them to be passed like so:  
http://localhost/products/search?page=1&per=10&group_by=manufacturer_id+asc&order_by=vendor_id+asc,vendor_number+desc

Sorting (order_by) - works fine. But grouping causes an error: Uncaught TypeError: undefined is not a function  

Here is my code:




crudServiceBaseUrl = "/products";

productsDataSource = new kendo.data.DataSource({
  autoSync: true,
  pageSize: 10,
  serverPaging: true,
  serverSorting: true,
  serverGrouping: true,
  schema: {
    data: "products",
    total: "count"
  },
  batch: false,
  transport: {
    read: {
      url: crudServiceBaseUrl + "/search",
      dataType: "json",
      contentType: "application/json",
      type: "GET"
    },
    update: {
      url: function(expense) {
        return crudServiceBaseUrl + "/" + expense.id;
      },
      dataType: "json",
      contentType: "application/json",
      type: "PUT"
    },
    destroy: {
      url: function(expense) {
        return crudServiceBaseUrl + "/" + expense.id;
      },
      dataType: "json",
      type: "DELETE"
    },
    create: {
      url: crudServiceBaseUrl,
      dataType: "json",
      contentType: "application/json",
      type: "POST"
    },
    parameterMap: function(data, type) {
      if (type === "read") {
        return {
          page: data.page,
          per: data.pageSize,
          group_by: function() {
            var groupings;
            if (typeof data.group === "undefined") {
              return "";
            } else {
              groupings = $.makeArray(data.group);
              return $.map(groupings, function(g) {
                return g.field + " " + g.dir;
              }).join(",");
            }
          },
          order_by: function() {
            var sortings;
            if (typeof data.sort === "undefined") {
              return "";
            } else {
              sortings = $.makeArray(data.sort);
              return $.map(sortings, function(s) {
                return s.field + " " + s.dir;
              }).join(",");
            }
          }
        };
      }
    }
  }
});

products_grid = $("#products_grid").kendoGrid({
  dataSource: productsDataSource,
  groupable: true,
  sortable: {
    mode: "multiple",
    allowUnsort: true
  },
  pageable: true
});

Hy,

I've got a Column with DateTime Values! eg.: "2014/09/11 10:00"

Our Customer wants to filter the Column by Datepicker and only one field (filterable.extra: false) - so if I add a Datepicker Filter (not DateTimepicker) and wanna filter "is equal" to "2014/09/11" the Grid don't wanna display anything - Problem ist that the filtered Date is "2014/09/11 00:00", whicht isn't equal because of the time - how can I fix this issue?

In the Column I have to display the date with the time, filtering should ignore the time!

greetings from Austria

I tried updating my grid to use 2014.2.903 version of kendo.min.js and kendo.angular.min.js, but when I do, code that was working formerly no longer works.

Specifically this snippet in the initialization of grid columns is where I get an error:


It complains that kendoDropDownList is not something that can be done to "input". Type of input shows as Object, or if you look further into the properties it is correctly identified as an INPUT.

Putting back the former *.js files returned my app to working as before.

Hello
I have following data:

user_id, user_first_name, user_surname, some_other_data

On Grid I'm displaying it in following way

UserDisplayName (user_first_name + ' '+ user_surname), Some Data

Now I would like to group data by user. So in fact on database level it should be grouped by user id but then it should display in grid group header proper user display name.

I know how to achieve such grouping by simply replacing proper memeber in group descriptor on DataSourceRequest object, but Then group header is wrong.
Probably it would be possible to somehow on fly replace that values?

But I believe it would be still a problem with sorting.

Is such server grouping is possible? In linq I can define multiple columns to group, but have no idea how to apply that to data source.

Kind Regards
Marcin

I want to have a 'begin --> end' date range show when date columns are filtered.

This code snippet works, the first time the filter is opened:

However, the next time it is opened, the gte option is shown for both the zero-eth and the 2nd operators. The filterMenuInit is never hit again. How can I make it persist?

Thanks, Bob Graham
