Hello friends,

For the  Kendo Grid, when we add a new record, a date field is always the default value 01/01/0001 in the post back record. It should return the input date value rather than 01/01/0001 (or null if this date field is not required)

However, when we update this 01/01/0001 field in this new created record, the correct date value is returned in the post back record and can be updated successfully.

We are using VS 2022. (When checking mdGiving, we found that date field value is always 01/01/0001 no matter what we entered for that field in the grid.)

        }

Any ideas?

Thank you very much for your help.

Hi, buttons in toolbar template are smashed together after loading a saved grid state. The problem can be reproduced in demo application https://github.com/telerik/ui-for-aspnet-mvc-examples/tree/master/grid/grid-preserve-server-toolbar-template-after-set-options

I have used the same code for at long time without issues but this was just noticed during testing. Please see attached images to see how the buttons are smashed together after pressing Save-/Load Settings.

Please advise.

Hi,

I am working on a grid having inline edit functionality.  I am trying to create a dropdown which display a list of persons, however, I want to save the email id of the person in our backend SQL DB.

I am trying to implement this with editor template approach -

I have tried the below code -

Grid:

columns.Bound(mm => mm.Person).Title("Assigned To").EditorTemplateName("PersonList").HeaderHtmlAttributes(new { style = "white-space: normal" });

PersonList.chstml

@(Html.Kendo()
            .DropDownList()
            .Filter("contains")
            .Name("Person")
            .DataTextField("Name")
            .DataValueField("Email")
            .DataSource(dataSource =>
            {
                dataSource.Read(read => read.Action("GetPeopleByArea", "Common").Data("getPeopleByArea"))
                .ServerFiltering(true);
            })
            //.HtmlAttributes(new { required = "required", data_required_msg = "Select Person Name", style = "width: 100px" })
            .ValuePrimitive(true)
            .AutoWidth(true)
            .OptionLabel("-- Please Select --")            
    )

function getPeopleByArea() {
        var grid = $("#Grid").data("kendoGrid");
        var dataItem = grid.dataItem("tr.k-grid-edit-row");
        return {
            Area: dataItem.Area
        };
    }

When I edit the grid the dropdown work list works fine and it displays the filtered list of people as expected.  However, Instead of the email id the record is getting updated with Null or blanks in the backend table.

However, this approach works fine if I do not use getPeopleByArea function to filter the area based on certain conditions and use a different controller function to get the whole list.

Also, if I am using  .DataTextField("Name") and  .DataValueField("ID"), ID is getting stored and same is getting displayed on the grid instead of the Name.

What am I doing wrong here ? Can anyone please suggest.

Please let me know if you have any questions.

Thanks

ASP 4.8 MVC application using kendo 2023.2.606

Have a page w/ a grid on it - bound to a list in my model - and wanted to add a default sort.  

Here's a stripped down version of my grid:

@(Html.Kendo().Grid(Model.RepList)
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(p => p.SalesRepname).Title("Sales Rep");
    })
    .Sortable()
    .Pageable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .Sort(sort => sort.Add("SalesRepname").Ascending())
        .ServerOperation(false)
     )
)

The default sort works - but the UI presents a double-sort arrow.  Clicking the column again re-sorts the column - flipping both arrows the other direction.  Is there a workaround for this bug to only have one sort arrow?  or is there a fix for this in an upcoming release?

Was originally doing this with ASP.NET AJAX WebForms Telerik Grid, but because of walls we hit with other functionality we are moving page to MVC.

Thing of Order Line and then as detail table we have Line Items. The Order Line has a Category Drop Down. When the Order Line Category gets changed all the Line Items must be changed to the same Category of the Order Line. If a Line Item category is changed then if all the Line Items have the same category then the Order Line needs to get changed to the category of all the Line Items. If all of the Line Items arent the same then the Order Line must be changed to the "Multiple" category.

We have been able to make changes to the datasource of the Line Items and if you click on the drop down in a Line Item the DropDown will change and the Category of the Order Line is shown as selected, but not until then.  When page 1st renders the Order Line has a drop down with "Category One" showing, then all the Line Items will also show that category in the drop down. If you change the Category of the Order Line with say "Category Two" the line items get changed, but user doesnt see in grid. If the user clicks on the Line Item dropdown the drop down appears and the item selected shows "Category Two".

How to make this work as desired with MVC and Kendo?

hi,

When Multi checkbox column is enabled in MVC Kendo Grid, it keeps spinning and not loading filter checkboxes for large dataset.
Please find the sample code attached.

We use Kendo.Mvc, Version=2022.1.412.0.
This sample code uses lesser version.

@(Html.Kendo().Grid<TelerikMvcApp6.Models.OrderViewModel>()
            .Name("grid")
            .Columns(columns =>
            {
                columns.Bound(p => p.OrderID).Filterable(false);
                columns.Bound(p => p.Freight);
                columns.Bound(p => p.ShipName);
                columns.Bound(p => p.ShipCity).Filterable(f => f.Multi(true).Search(true));
            })
            .Pageable()
            .Sortable()
            .Scrollable()
            .Filterable()
            .HtmlAttributes(new { style = "height:550px;" })
            .DataSource(dataSource => dataSource
                .Ajax()
                .PageSize(10)
                .Read(read => read.Action("Orders_Read", "Grid"))
            )
        )

Using a (ASP.NET Core) Kendo spreadsheet, how to know if on the sheet are or not validation errors and what kind of if any.

I used this code to add validation

myCell.Validation(v => v
    .ComparerType("custom")
    .DataType("custom")
    .From("R[0]C[0] > 0")
    .Type("warning")
    .ShowButton(true)
    .AllowNulls(true)
    .TitleTemplate("Alerte de validation")
    .MessageTemplate("Attention, cette valeur est négative !"));

Hi, I'm updating our version of the Kendo Grid from 2021 (don't recall the exact version) to 2023.1.117 and, among other changes, it seems that the following syntax for binding the Description property to data_description is no longer valid:

 columns.Bound(w => w.Description).Width(100).Title("Description")
            .HtmlAttributes(new { @class = "someClass", data_description = "#=Description#" });

Similar to what is shown at the bottom of this thread:

https://www.telerik.com/forums/creating-data-bound-html-attributes-in-mvc-grid-cells

This was working prior to this update, but I can't find any documentation on the change within the site and the grid example shown here:

https://demos.telerik.com/aspnet-mvc/grid

seems to indicate that it should still work this way, though that example may be outdated.

Note that the same Description property, referenced the same way (#-Description#) still works inside of a ClientTemplate.

I'm getting this message whenever I try and load a page containing a grid.  I tried installing the Telerik.SvgIcons and Telerik.FontIcons packages, but both installations fail because of an error when installing System.Net.Http.  Is there anyway I can just install the two files so that I can resurrect my .NET MVC 4.7.2 application?

The error I get while install the packages is:

Error Failed to add reference to 'System.Net.Http'.
The operation is not allowed because currently this object is not parented.

System.Net.Http version 4.2.0.0 is installed, but installing the most recent version 4.3.4 fails, whether or not there is a reference to 4.2.0.0.
