How to setup imput ou time in Grid (jquery)

How setup griid column in jquery.

I use this format, bit on input I get a date on the dropdown, not the time to chose

I need just the the time part, the date part is from "dataIni" field.

Another issue is the inline errors. I get error on field "hIni1" not on "Inicio 1"

$("#horarios").kendoGrid({
height: 550,
sortable: true,
pageable: true,
height: 550,
toolbar: [{ name: "create", text: "Inserir" }],
columns: [
{ field: "dataIni", type: "date", format: "{0:yyyy-MM-dd}", title: "Data Inicio", width: "250px" },
{ field: "hIni1", type: "date", format: "{0:HH:mm}", title: "Inicio 1", width: "120px" },
{ field: "hFim1", type: "date", format: "{0:HH:mm}", title: "Fim 1", width: "120px" },
{ field: "hIni2", type: "date", format: "{0:HH:mm}", title: "Inicio 2", width: "120px" },
{ field: "hFim2", type: "date", format: "{0:HH:mm}", title: "Fim 2", width: "120px" },
{ command: ["edit", "destroy"], title: " ", width: "250px" }
],
editable: "popup" // OR editable: { mode : "popup" }
});

Best regards

Weird Combobox UI Behavior after a value is set on DataBind

Hey all,

I'm fairly new to kendo and have a bit of an problem ->

I'm currently troubleshooting a weird issue in version 2019.1.220. I'd love to upgrade but its not feasible for this project at this time.

Basically, what is going on is that we're seeing some weird behavior with the Combobox control after databind. Data comes from the database and is set in the control. When the Arrow (Open button) is clicked its almost as though it doesn't do a read on the datasource because I get the No items found message. However, if I change the selected text on the control it will do a pop open and locate the item in the list.

While trying to solve this with a work around I have tried to subscribe to the click event on the control and force a search function call in Kendo using the following:

    $(document).ready(function () {
        var itemCombo = $("#Items").data("kendoComboBox");
        itemCombo.input.on("click", function () {
            itemCombo.search(itemCombo.text);
        });
    });

This does seem to force a search to run on click of the control - however the arrow button on the control still does what it did before - not read the list or search for the item. Does anyone have any quick tips on how i can access the click event on the arrow button itself? The Open event isn't a good option - if I call .search on that it will cause an endless loop activity.

I'm sure this has been solved already in later versions but upgrade is not an option at this time.

Appreciative of any pointers! Thanks!

Selected Option - Virtualization Dropdown

Hi guys,

I've implemented virtualization over a dropdown which has a lot of items/rows (more than 3k) so I went with this approach. The issue now is that the dropdown always selects the first option no matter if i specify the value in any way. Any advices or any guide to fix this?

Best regards.

Jump to specific record in grid

I am using the grid and need to be able to programmatically select a specific row based on the value of one field, and then scroll to that row if it isn't already visible. I can't find any way of doing that. If it matters, I'm not using paging. Is there a way to do this?

I have some issue regarding the kendo UI Grid Pagination Customization part

what is actual behavior
Default kendo UI behavior is like we need to render all the grid data once to activate pagination functionality if pageSize <= actual records then and then the only pagination will active but if we got pageSize > actual records the pagination won't work.

what is expected behavior
I need to set pageSize = 50 and API return me 50 records with total records field so, for now, we can assume that API return total 50 records and it has fields to indicate total records which let's say 200 so pagination will set accordingly [ 200 (total) / 50 (pageSize) = 4 page ] and pagination will active also with the pageSize <= actual logic and we can call separate API call for next 50 records after we click on next button which is been created on total records.

constructor( private router:Router,private httpclient:HttpClient,private EncrDecr:EncrDecrServiceService) {
    this.GetUserList();
   }
    modeldata:any={
    UserName:'',
    UserEmail:'',
    IsActive:'',
    sortable:true,
    PageSize:this.pageSize,
    PageNumber:this.pageNumber,
    SortParam:this.sortColumn,
    sortType: this.sortType
   };
   GetUserList(){
     
    this.httpclient.post(this.baseUrl+'UserDetail/GetAllGridData',this.modeldata).subscribe(res=>{
      this.gridList = res;
      this.gridData=this.gridList['Result'];
      this.items= this.gridData;
    },(error)=>{
      const err= error.error;
    })
   }
  breadCumb(){
    this.router.navigate(['/Home']);
  }
  newUser(){
    this.router.navigate(['/ManageUser']);
  }
  
  pageChange(event: PageChangeEvent): void {
    this.skip = event.skip;
    this.loadItems();
  }
  loadItems(): void {
    this.gridData = {
      data: this.items.slice(this.skip, this.skip + this.pageSize),
      total: this.items.length,
    };
  }
  public sort: SortDescriptor[] = [
    {
      field: "UserName",
      dir: "asc",
    },
  ];
  public sortChange(sort: SortDescriptor[]): void {
    this.sort = sort;
    this.modeldata.sortType= sort[0].dir;
    this.modeldata.SortParam=sort[0].field;
    this.GetUserList();
    this.loadProducts();
  }
  
   loadProducts(): void {
    this.gridData = {
      data: orderBy(this.gridData, this.sort),
      total: this.gridData.length,
    };
  }
  
  ngOnInit(): void {
    this.gridData = this.loadItems();;
   
    
  }

Accessibility issues in Grid pager: Broken ARIA reference in link (next, first, previous, last)

When you evaluate a page, with a kendo grid inside, accessibility tools like WAVE (https://chrome.google.com/webstore/detail/wave-evaluation-tool/jbbplnpkjmmeebjpijfedlgcdilocofh), show errors on "pager links".

These errors are Broken ARIA references: An aria-labelledby or aria-describedby reference exists, but the target for the reference does not exist.

The links have the aria-describeby attribute, but the reference does not exist.

Thanks!

Multiple Accessibility Issues with Kendo Controls after Update

We updated Kendo UI for JQuery from v2021.2.511 to v2022.1.325 and we observed that certain screen reader functions were broken.

The following issues were observed when screen reader is activated on any KendoMultiSelect control:

a. The selected item and tag are not being announced. The selected item and the tag were announced by narrator before the update.

b. The number of available suggestions is not announced. This was announced before the update.

c. When scan mode is activated, users cannot navigate the list items using the up/down arrow keys.

d. When a user enters a search string that is not in the datasource, narrator does not announce that. Before the update, narrator would announce "Selection contains zero items".

For other controls like checkboxes, narrator does not announce the name or label of the controls when in focus.

Is there a different attribute other than aria-label that we need defined on these controls to get screen readers to announce them?

I'd appreciate any help to get these issues fixed.

Thanks!

I try to keep filter value on reload but not working.

Hi,

I'm trying to keep the filter value into KendoGrid and reuse it on relaod.

I find some code sample but doesn't working. I used getOptions to store values into localStorage. It's working. I have values into localStorage["kendo-grid-options"]. On reload, value appears into filters on header grid but data don't load. Error in the consoel is :

[! - SessionID: q0pbq0zsol3mjsxtd5mlendu, PageInstanceID: d11a8e2e-d716-43a0-8f4e-679eb87ad167, DateTime: 04/20/2022 20:53:10.894] Message: Uncaught
TypeError: Cannot read properties of undefined (reading 'data')

Impossible to find solution. If somebody has en idea... :)

My code is the following

function LoadSampleQualityControlPlanGridSummary(control,params)
{
control.dataSource = new kendo.data.DataSource({
transport: {
read: function (options) {
GetDsBySp("sp_HMI_GetSampleControlPlanList", params, options.success);}
},
schema: {
model: {
id: "qm_spec_id"
},
fields: {
qm_spec_desc: {
type: "string"
},
plan_name: {
type: "string"
}
}
}
});
}

function InitSampleQualityControlPlanSummaryGrid(control) {
control.columns = [
{
field: "qm_spec_name",
title: "Name")
},
{
field: "qm_spec_desc",
title: "description")
},
{
field: "plan_name",
title: "Plan",
}
];
}

//On load
_controls.SampleControlPlanSummary = control.findByXmlNode("GSQCP");
_controls.$SampleControlPlanSummary = $(_controls.SampleControlPlanSummary.domElement).data("kendoGrid");

InitSampleQualityControlPlanSummaryGrid(_controls.SampleControlPlanSummary);

var options = localStorage["kendo-grid-options"];
if (options) {
var parsedOptions = JSON.parse(options);
_controls.$SampleControlPlanSummary.setOptions(parsedOptions);
_controls.$SampleControlPlanSummary.setDataSource(gridData);
}
LoadSampleQualityControlPlanGridSummary(_controls.SampleControlPlanSummary, paramControl);
