Dynamic Grid produces a RunTimeException when the Filterable() configuration is enabled
System.ArgumentNullException: Value cannot be null.Example
@model System.Data.DataTable
@(Html.Kendo().Grid<dynamic>()
.Name("gridItem")
.Columns(columns =>
{
foreach (System.Data.DataColumn dcolumn in Model.Columns)
{
columns.Bound(dcolumn.ColumnName).Title(dcolumn.Caption);
}
})
...
.Filterable()
)
The aforementioned declaration will work in the previous 2024.3.1015 version of the suite.
The Grid makes the application throw a runtime error.
The Grid makes the application should not throw a runtime error.
By default, when the "paste" command is added, the default option is "insert" mode ("Paste (Insert)"). Is it possible to add an option that allows setting the default paste mode to "replace" ("Paste (Replace)")?
The custom ordering of the filter values in the Telerik UI ASP.NET Core Grid does not function correctly when using TagHelpers.
A REPL sample for reproduction: https://netcorerepl.telerik.com/wIYNvEvn00CAqNGL14
The filter values should be presented in the same order as specified in the Filterable configuration.
In a .NET 7 project when TagHelper Grid is configured and RuntimeCompilation is employed, starting from version 2023.2.606 an unhandled exception is thrown.

When run a runtime error occurs
TagHelper Grid should exhibit the same behavior as HtmlHelper ones.
Is it possible to implement template options for the "update" and "cancel" column commands of the Grid?
For example:
$("#grid").kendoGrid({
columns: [{
command: [{
name: "edit",
template: {
update: "<button class='customUpdate'>Save</button>",
cancel: "<button class='customCancel'>Cancel</button>",
}
}]
}],
...
});
Currently, when using the default Grid search functionality and the column filter menus, we observe the following:
However, there’s a specific scenario where this does not work properly:
For example:
This functionality behaves correctly in the Telerik UI for Blazor Grid component - the search and column filters are managed as separate objects.
Is it possible to enhance the Grid filtering similar to the Blazor Grid?
Hi, is there a way to configure the grid so that when it's grouped and later sorted, the grouping state (expanded/collapsed) is preserved?
Kind Regards

It would be convenient to have built-in MultiColumnComboBox editing for the Grid.
I was hoping the component would show the addresses formatted in columns (as per a fields list) and then return the address concatenated into a single to the grid field (e.g. from .DataTextField("FullAddress")).
Grid Hidden Column is set as exportable by default for Pdf and Excel
The Grid Hidden Column should be set as exportable by default for Pdf and Excel.
The Grid Hidden Column should not be set as exportable by default for Pdf and Excel.
When the Grid is nested in a relatively positioned container, during the export the Grid gets an overflow style to its wrapping element. Then the style is removed and re-added again. This happens in a loop, which results in a vertical scrollbar constantly appearing and hiding.
Flickering caused by a scrollbar appearing and hiding
The Grid should remain unchanged during the export and no scrollbar should appear and hide during the export.
When creating columns in a TagHelper Grid definition, the Width property allows only numbers:
<column field="OrderID" width="100">
</column>This does not match the width property in the Kendo UI and HtmlHelpers Grid definitions which allow string values to be entered as well:
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/columns.width
That way, the developer will be able to add rem and other unit values in TagHelper syntax as well.
Also, it would be convenient if there is a new property similar to this:
<column field="OrderID" tooltip="Unique Number of the Order">
</column> <column field="Freight"
html-attributes='new Dictionary<string, object>{ ["style"] = "width: 30rem;" }'>
</column>
### Bug report
When the Grid is grouped by a specified column, and this column has a "groupFooterTemplate" that contains aggregates from other fields, it cannot be exported to Excel. It throws a JavaScript exception.
### Reproduction of the problem
1) Group the Grid by the column "ProductName".
2) Export it to Excel through the built-in command "Export to Excel".
3) JS exception is thrown.
A Dojo sample for reproduction: https://dojo.telerik.com/UyUruyOZ
### Expected/desired behavior
The Excel export should work as expected when the Grid is grouped.
### Environment
* **Kendo UI version: 2022.2.802
* **jQuery version: 1.12.4
* **Browser: [all]
At this stage, the ToolBar.Custom() API configuration does not expose built-in configurations for adding a handler and partial view. E.g:
@(Html.Kendo().Grid <TelerikAspNetCoreApp455.Models.OrderViewModel>()
.Name("grid")
.ToolBar(toolbar => {
toolbar.Custom().Name("Test1").ClientTemplateHandler("someHandler");
toolbar.Custom().Name("Test2").ClientTemplateView(Html.Partial("_Test2"))
})
...
)The ToolBar.Custom() API configuration does not expose built-in configurations for adding a handler and partial view.
The ToolBar.Custom() API configuration should expose built-in configurations for adding a handler and partial view.
Reproducible with the Grid's tag helper. Works as expected in the Html helper.
The toolbar does not show the RadioGroup.
A RadioGroup should appear in the toolbar, as set in the toolbar command template:
<toolbar-command-template>
<kendo-radiogroup name="test">
<kendo-radiogroup-items>
<kendo-radiogroup-item label="Factor" value="F"></kendo-radiogroup-item>
<kendo-radiogroup-item label="Equation" value="E"></kendo-radiogroup-item>
</kendo-radiogroup-items>
</kendo-radiogroup>
</toolbar-command-template>
Setting the Reoderable.Rows.ClickMoveClick() API configuration explicitly to false results in an error when using the HTML Helper wrappers.
Setting the Reoderable.Rows.ClickMoveClick() explicitly to false throws the following error:
Setting the Reoderable.Rows.ClickMoveClick() explicitly to false should not throw an error.
### Bug report
The "confirmation" attribute of the editable tag does not accept a string.
### Reproduction of the problem
Add a confirmation text as a string in the "confirmation" attribute, as per the example below:
<kendo-grid name="grid">
...
<editable mode="popup" confirmation="Are you sure you want to hide this invoice?" />
</kendo-grid>
A REPL sample for reproduction: https://netcorerepl.telerik.com/moEqPSFo32PrwW4d01
### Expected/desired behavior
The "confirmation" option must accept a string.
### Environment
* **Telerik UI for ASP.NET Core version: 2024.2.514
* **Browser: [all]
### Bug report
The Column.Exportable option is not correctly serialized and cannot be used to export hidden columns.
### Reproduction of the problem
1. Set Column.Exportable(true) and Column.Hidden(true).
2. Export the grid and see that the column is not present in the exported file.
