I have implemented a simple Kendo grid in ASP .Net Core which should bind the data on DataSoruce Read request. In actual it is not binding data in read request but binds the data whenever i click on 'refresh' icon under pagination. Below is my code - 

<div class="grid-container">

        @(Html.Kendo().Grid<CAMPv2.Models.AutoPoco.Role>()
    .Name("RolesGrid")
    .Columns(columns =>
    {
        columns.Bound(c => c.Name);
        columns.Bound(c => c.NormalizedName);
        columns.Bound(c => c.Description);
        columns.Bound(c => c.Status);
    })    
    .Scrollable()
    .Sortable()
    .Pageable(pageable => pageable
    .Refresh(true)
    .PageSizes(true)
    .ButtonCount(5))
    .DataSource(datasource => datasource
    .Ajax()
    .Read(read => read.Action("GetRoles", "Role"))

    )
    )
    </div>

Below is code behind - 

[HttpPost]
        public IActionResult GetRoles([DataSourceRequest] DataSourceRequest request)
        {
            List<Role> _lrolePermissionDetails = _tableOperations.GetAll<Role>(ApplicationConstants.CONNECTOR_AUTOPOCOAUTH, "Role", _loggingService).ToList();
            return Json(_lrolePermissionDetails.ToDataSourceResult(request));           
        }

Please let me know what i am missing here.

Thanks,

Hi Telerik,

When I use the "services.AddKendo();" command,the program gives the following message.

I have followed the instructions on your page, the situation has not changed.

I first tried it with version 2016.3.118, then I tried it with the latest promotional version, the message has not changed.

Best regards,

Mehmet Bingol

I'm trying to create a toolbar with a dropdown menu in my grid, similar to the demo shown here: https://demos.telerik.com/aspnet-core/grid/toolbar-template.

I can not find any information on doing it with tag helpers.

How get value from inputbox of selected checkboxitem(and subitems)? I can get label of checked item(item.Name), but i don't now how get value of inputbox.

<script id="treeview_distribute_template" type="text/kendo-ui-template">
                                                            <table>
                                                                <tbody>
                                                                    <tr>
                                                                        <td width="500px;">
                                                                            #= item.Name # &nbsp;
                                                                        </td>
                                                                        <td >
                                                                            <input id='comment_input' type='text' style="width:500px;" />
                                                                        </td>
                                                                    </tr>
                                                                </tbody>
                                                            </table>
                                                        </script>

 function getCheckedItems(treeview) {
        var nodes = treeview.dataSource.view();
       
        return getCheckedNodes(nodes);
    }

    function getCheckedNodes(nodes) {
        var node, childCheckedNodes;
        var checkedNodes = [];

        for (var i = 0; i < nodes.length; i++) {
            node = nodes[i];
            if (node.checked) {
                checkedNodes.push(node);
            }

            if (node.hasChildren) {
                childCheckedNodes = getCheckedNodes(node.children.view());
                if (childCheckedNodes.length > 0) {
                    checkedNodes = checkedNodes.concat(childCheckedNodes);
                }
            }

        }

        return checkedNodes;
    }

Hello,

Looking for an easy solution to enable/disable all grid rows based on other values/selections on the page.

The following selectable parameters for the grid gives me exactly what I need but I need to be able to configure the grid based on the user's input values on the page.

I've tried using the following jquery to toggle the rows, with no luck.  'enabled' is the parameter passed to the function.

Any suggestions on how I can achieve the functionality needed with the grid component?

Thanks.

Jason

The demo here: https://demos.telerik.com/aspnet-core/autocomplete/clientfiltering

is missing this script which is in the other demos.

<script>
      function onAdditionalData() {
      return {
          text: $("#[your control's name]").val()
      };

</script>

It would be helpful to be able to report these things from the page.
