showColumn() and hideColumn() is great, but it would be nice if we could pass multiple columns to the methods (maybe as an array).

It's extremely slow if I create a loop and call show/hideColumns(x) multiple times.

This would ideally apply to any grid component (Kendo Grid and TreeList).

When performing a grid refresh, the grid re-renders the all the grid rows. 
I think it would be very efficient to have a choice to render specific, changed rows. 
This is valuable if the grid has many items (200 items for example).

The Kendo-UI Grid supports the concept of locked columns that are always on the left side of the screen (in a non-RTL-world) and do not scroll. This makes it necessary to split the underlying HTML-table into two parts (one is locked and one is not). Kendo-UI takes care of syncing the height of the rows between those two tables.

However, if there are empty cells in the locked part, this logic produces results that make the row grow larger (higher) than if there was content. This DOJO demonstrates the behaviour. Using the Browser's DEV-Tools, you can see that rows without content in column A are 37px high, while those with content are only 36px high.

Hiding the first column in Grid will show a 2 pixels left border instead one.

Dojo Sample to replicate the issue: https://dojo.telerik.com/ubaLiYEN

Steps:

1. Hide the first column (OrderID) from the Column Menu.

2. Notice the doubled left-border on the left hand side of the Grid.

Hello,

 

we have the following problem:

In the dojo https://dojo.telerik.com/uJUGEQuh clicking on a row from the skleton loader in the grid causes an error. It seems like you want to access the "id" field from the datasrouce model which doesn't exist in the loading animation.

model:
{
	id: "Id",
	fields: 
	{
		ProductName: { type: "string" },
		Id: { type: "number" }
	}
}

 

If you rename the "id" field to for exmaple "XXXX" the error message changes

from:

Uncaught TypeError: Cannot read properties of undefined (reading 'Id')

to:

Uncaught TypeError: Cannot read properties of undefined (reading 'XXXX')

 

We attached a gif of the problem and the code snipped of the dojo. The browser is Chrome Version 109.0.5414.120 (Official Build) (64-Bit)

 

Greetings

Ingo E.

Bug report

When the value of a cell in the Grid is set using the model.set method, and there is already a dirty cell in the Grid, the .k-dirty-cell class is added to multiple cells.

Reproduction of the problem

  1. Open the Dojo - https://dojo.telerik.com/@NeliKondova/OhoPEPoh
  2. Change the value in an arbitrary cell in the Grid.
  3. Press the setValue button (The set value button is setting the value of the third cell in the ProductName column using the API set method)

Current behavior

The k-dirty-cell class is applied to multiple cells (the background is changed to green).

Expected/desired behavior

The .k-dirty-cell class should be applied only to the cells with changed value.

The issue is a regression starting with the 2023 R1 (2023.1.117) version.

Bug report

When the selectable option is set to "multiple cell" and the user tries to select the content of a single column, the content of the entire row is selected.

Reproduction of the problem

  1. Open the Dojo - https://dojo.telerik.com/@NeliK/AzirANuT
  2. Try to select the text in the France cell and drag down to select only the content in the ShipCountry column.

Current behavior

The content of the other columns is selected as well - https://somup.com/cZeXIvpRzk

Expected/desired behavior

The behavior is expected when the allowPaste option is enabled. However, once the allowPaste option is disabled only the content of the selected column should be selected.

Workaround

kendo.ui.Selectable.fn._allowPreventDefault = () => true;

I am trying to change the menu option for a column from false to true and others from true to false when a user selects an item from a dropdown. This isn't working. I'm using getOptions(), changing the menu setting in each column, and then setOptions(options) to set it.

Here is a dojo showing an example. In the example, firstName and lastName are initially hidden. I simulate a user choosing last name from some sort of selector (like a dropdown box). The code should then hide both name columns and unhide the lastName column. Instead it hides both name columns.

It seems to have something to do with setting any of the name columns to hidden on initialization. If I remove this from the column settings on initialization though it only works once and when I choose a different option from the dropdown (dropdown is simulated in the dojo so you can't try this but trust me) it breaks.

I want to use multi-checkbox filtering with complex datasource. However, the name of the field on which the filtering needs to be applied is not the same as the column field. Thus, in order to avoid custom implementation I would like to have an option to set which is the field that should be used for the filtering.

For example, in the Dojo linked here, I would like to filter the country column, but the filter field in the filterable datasource is 'id'.
