Hello,

is there a way to overwrite the browsers (chrome and firefox) default behavior for middle or right click on custom buttons in a grid?

We are trying to get the middle mouse click on a custom command button in a grid.

With this line we only get the left mouse click, the middle and right are ignored/use the default browser commands 

command.Custom("Details").Text(" ").Click("showDetails").IconClass("fas fa-eye");

Middle - new tab

Right - context menu

We tryed using JS on the mousedown event but it didn't work and in the "showDetails" method we only get the left mouse button

$('.k-grid-Details').on('mousedown', function (e) {
    debugger
     if (e.which == 1) {
       e.preventDefault();
       alert("middle button");
});

How do I call my MVC Core Controller Actions for Create, Update, and Delete from the Grid and Grid Rows.  My previous version used the following code, but the new Core version does not work:

c.Bound(m => m.DeliveryDocumentNumber).ClientTemplate(Html.ActionLink("Edit", "Edit", "Orders", new { id = "#=Id#" },     null).ToString()).Title("").Filterable(false).IncludeInMenu(false);
c.Bound(m => m.DeliveryDocumentNumber).ClientTemplate(Html.ActionLink("Details", "Details", "Orders", new { id = "#=Id#" }, null).ToString()).Title("").Filterable(false).IncludeInMenu(false);

c.Bound(m => m.DeliveryDocumentNumber).ClientTemplate(Html.ActionLink("Delete", "Delete", "Orders", new { id = "#=Id#" }, null).ToString()).Title("").Filterable(false).IncludeInMenu(false);

I want to use the Controller Views for CRUD operations and not the Grid since the Grid only shows a subset of the data.

Thanks.

I am getting complains from our customers that they cannot right click and paste into the Editor tool. I tested this in IE11, Chrome, and Firefox. The only one that could do a right-click and paste was Chrome. The other browsers, you have to Ctrl+V.

 

Is there a fix for this?

 

Here is my code for the editor:

@(Html.Kendo().EditorFor(o => o.Content)
.Encoded(false)
.Resizable(true)
.Tools(tools => tools
.Clear()
.Bold()
.Italic()
.Underline()
.Strikethrough()
.JustifyCenter()
.JustifyFull()
.JustifyLeft()
.JustifyRight()
.InsertUnorderedList()
.InsertOrderedList()
.Indent()
.Outdent()
.CreateLink()
.Unlink()
.TableEditing()
.Formatting()
.CleanFormatting()
.FontName()
.FontSize()
.ForeColor()
.BackColor()))

My kingdom for a good sample.

I am trying to use a custom popup template with a couple of dropdownlists and have them cascade. This is in asp.net core (NOT MVC).

My big questions are how to do the cascade and pass forgeryToken with it and how to receive the cascade call (i.e. the function signature). Below is what I have now and it doesn't work.

Another question I have is, what should the signature of the c# function be for the second (traits) dropdown be on the server.

Currently, I have:

public ActionResult OnPostCropsReadAsync([DataSourceRequest] DataSourceRequest request)

How do I get the id of the first dropdownlist to know how to filter?

THanks … Ed

Here's the popup template and below that is the calling grid.

If you look at the demo https://demos.telerik.com/aspnet-core/drawer/tag-helper, you can expand the drawer but as soon as you click one of the drawer items it auto-collapses. How can we avoid this behavior and keep the drawer expanded?

MVC Telerik 2019.2.619;  Windows 10; Visual Studio 2017

I have a grid on a view and as long as I don't scroll horizontally I can resize the columns.  Once I move the horizontal scrollbar just a little the resize handle moves also.  Instead of finding it on the line between the columns it is found over in the column header area.  Any idea what I am missing here?

Rich

 

My controller code for the read:

[HttpPost]
        public IActionResult IssuesGrid_Read([DataSourceRequest]DataSourceRequest request)
        {
            List<IssuesForGrid> myData = new List<IssuesForGrid>();
            myData.Add( new IssuesForGrid
            {
                IssueNumber = 1,
                NonIngallsIssueNumber = "ABC-1",
                Project = "PROJ1",
                ShortDescription = "This is a test",
                DetectionDate = DateTime.Now,
                DetectedBy = "George",
                Severity = "Low",
                Status = "Open",
                AssignedTo = "Mike",
                ActionNeeded = true,
                ActionNeededText = "Fix it",
                Ecd = DateTime.Now,
                DecisionNeeded = true,
                DecisionDetails = "What is wrong",
                Comments = "Not again lol"
            });

If I add several rows to my grid which is not bound to any data source, upon clicking the edit button of the first row and then clicking then edit of any other row. The first row of the grid is lost/deleted if the update button is not clicked.

This only happens a single time and never again after the first time it occurs on any action combination.

Would be helpful to know if there is a way to send only new items through the create transport instead of the entire grid also.

I've tried setting the model id, this doesn't fix the problem either problem.

 

<datasource>
        <schema>
            <model id="PrimaryId">
                <fields>
                    <field name="PrimaryId" default-value="1"></field>
                    <field name="PayDate" type="date" editable="true" nullable="false"></field>
                    <field name="ActivityStartDate" type="date" editable="true" nullable="false"></field>
                    <field name="ActivityEndDate" type="date" editable="true" nullable="false"></field>
                    <field name="ApprovalDeadlineDateTime" type="date" editable="true" nullable="false"></field>
                </fields>
            </model>
        </schema>
    </datasource>

 

logic to get around incorrect rows sent to controller through create transport

if (grid.dataSource.data().length == 0) {
            //defaulted today
            grid.addRow();
        }
        else {
            var newStartDate = AddDays(grid.dataSource.data()[grid.dataSource.data().length - 1].ActivityEndDate,1);
            var newEndDate = AddDays(newStartDate, 30);
            var newDeadline = AddDays(newEndDate, 5);
            var newPayDate = AddDays(newDeadline, 2);
 
            $("#PayrollPayRunGrid").data("kendoGrid").dataSource.pushInsert(grid.dataSource.data().length, {
                PrimaryId: currId,
                ActivityStartDate:newStartDate,
                ActivityEndDate: newEndDate,
                ApprovalDeadlineDateTime: newDeadline,
                PayDate: newPayDate,
            });
            currId++;
            grid.editRow($("#PayrollPayRunGrid tr:eq(" + (grid.dataSource.data().length) + ")"));
        }

Hello,

I have followed this Knowledge base article to adjust the boolean filters of the grids on my site : https://docs.telerik.com/kendo-ui/knowledge-base/grid-boolean-dropdownlist-filter

I am experiencing an issue also found in the preview available at the bottom of this article.

To experience the problem, try filtering by Discontinued column and select the False option. 

When the false option is selected in the dropdownlist, the "True" value is displayed but the "False" option is really selected. If you then hit the filter button, only the false values are shown as expected, but the label was showing "True". The behavior is as expected but the information shown to the user is misleading.

Any help on this problem would be appreciated!

Thank you very much!

Hi,

  I am working on a ASP.Net Core MVC project.

  When user click on the Detail button, i will return a partial view with a treeview in it.

  When the page is first loaded, i want the first item in the treeview to be selected programmatically after the Read() operation is competed. (Note: i want to avoid asking user to do that after the page is first loaded)

  Can you share with me how to achieve that?

Index.cshtml

@(Html.Kendo().TreeView()
    .Name("machinesTreeView")
    .DataTextField("MachineName")
    .TemplateId("treeview-template")
    .DataSource(dataSource => dataSource
        .Read(read => read
            .Action("Machines", "MachineDetails", new { productionLineName = Model.ProductionLineName })
        )
    )
)

 

script

<script>
    function onSelectMachine(e) {
        // load content into the pane with ID="detailsPane"
        var detailsUrl = '@Url.Action("Details", "MachineDetails")';
        $('#detailsPane').load(detailsUrl);
    }
 
    $(document).ready(function () {
        var treeview = $("#machinesTreeView").data("kendoTreeView");
        treeview.bind("select", onSelectMachine);
    });
</script>

 

controller

public async Task<IActionResult> Machines(string productionLineName)
{
    MachineDetailsModel model = await m_IFetchRealtimeData.GetMachineDetails(productionLineName);
    return Json(model.MachineInfosModel.OrderBy(x => x.MachineNo));
}
