I would prefer if you can use the FilterMenuTemplate in such a way that you can fetch also "filter criteria" from other fields/columns.

An example:

- grid has 3 coluns > Name, City, Population

- filter mode is set to filter menu and my filter menu should display at the first column.

- after the filter dialog is opened my expactation is that it includes also entries from other fields

In summary, my team would welcome the opportunity of central approach for filtering with multiple fields.

Documentation states that Grid supports Virtualization with Grouping if it is done by loading the Groups on-demand.

See:

On page: Blazor Grid - Load Group Data On Demand | Telerik UI for Blazor

From this, it appears that Virtual Scrolling, Group Load on Demand, and pagination of the results should function as expected.  I'm specifically focusing on the section where it says "load on demand for the data when the user expands a group or when they scroll to need a new set of available groups".

The behavior I am seeing in my Telerik Repl is not matching up with that.

See:  https://blazorrepl.telerik.com/QFbmurvT41eZq6Ld34

In the repl, I have added some Console.WriteLines to see when OnRead is actually called, as well as to log out some other information about the OnRead Request.  It can be seen that no pagination information is included in the request (PageSize = 0, Skip = 0) while the PageSize is set on the actual Grid component (PageSize = 20).

As a result, all groups are loaded initially, which will be problematic if my server-side data set is being grouped on a value that will result in thousands/millions of groups.

It is possible that I missed something in the documentation that would enable the expected behavior (the Grid actually giving me PageSize and Skip so pagination will actually work), but it is also equally possible that this was never intended behavior, and I have been misled by the documentation page.

When a filter descriptor is created and the value is of type DateTime? (nullable DateTime) the serialized value is incorrect.

    DataSourceRequest request1 = new()
    {
         Filters = new[] {new FilterDescriptor("Test", FilterOperator.IsEqualTo, DateTime.Now.Date) {MemberType = typeof(DateTime)}},
         Sorts = new List<SortDescriptor>()
    };

    DataSourceRequest request2 = new()
    {
         Filters = new[] { new FilterDescriptor("Test", FilterOperator.IsEqualTo, DateTime.Now.Date) { MemberType = typeof(DateTime?) } },
         Sorts = new List<SortDescriptor>()
    };

    string query1 = request1.ToODataString(); // outputs $count=true&$filter=(Test%20eq%202022-05-12T00:00:00.0000000Z)&$skip=0
    string query2 = request2.ToODataString(); // outputs $count=true&$filter=(Test%20eq%202022-05-12%2000:00:00)&$skip=0

As you can see in the provided example : https://blazorrepl.telerik.com/QcaiPbkL56qf6XQ747

I have the following situation. I'm using a custom editor template with two-way binding for the  column : OrderToEdit.ShipCity. If I change the value of this column in a row and press Enter, Tab or mouse focus out very quickly (immediately after value change),  UpdateHandler is triggered before the valueChanged event of the context and as a result changes are not shown. If there is a delay ( i.e 1 second ) all works fine. This is not happening when i'm using the builtin editor GridEditorType.TextBox. Could you provide me a solution ? 

There is another problem. if a click inside a cell edit mode is triggered. But if i click in a button in the toolbar or in column menu the cell remains open is not closed. I think this should not happen.

Hi,

We ran into an issue with manual binding and selected items with Grid component. I used the 'WebApiFromServerApp' sample in 'grid\datasourcerequest-on-server' folder from Telerik's samples on GitHub.

To recreate the issue, modify 'GridWithService.razor' file in 'WebApiFromServerApp' project. I attached modified project.

To test the behavior: 

1. Select records with Id 2 and 3 from grid.
2. Navigate to another page and return back to the first one.
3. Despite selected items exist in the grid's 'SelectedItems', but they are not being shown. This is the first issue.
4. The second issue is you can still select them again! In that case they would be duplicated as selected items.

Thank you.

When the state is loaded and there is a value in the search box, the X (clear button) is missing. 

Reproduction (if bug)

1. Create a Grid, set a SearchBox in the toolbar.
2. Set value in the SearchBox.
3. Save state.
4. Refresh the page and apply the state.
5. The value is present in the searchbox but the X icon is missing.

Expected (if bug)

The X icon should be visible.

Description

The left offset style value is not correctly formatted. It is culture-specific, however, the CSS rules should be formatted with culture invariant decimal separator - dot. 

Reproduction (if bug)

1. Create a grid with locked columns. 

2. Set the culture to one that has a comma as the decimal separator.

3. Resize the frozen columns, the left value is formatted with a comma instead of a dot.

Expected (if bug)

The value should be formatted with a dot.

Hello,

I seem to have stubled upon a strange bug in TelerikGrid. We have wrapped a TelerikGrid and the Columns are also wrapped to allow special actions.
The bug is present in "raw-telerik-code" as well.

We have an edge case where we have a TelerikGrid and some of its columns should be Locked (Stickied/Frozen) as a default behaviour.
But depending on user interaction we want to change the state. We cannot use a property for each column that we want to be Locked/Unlocked as it should be handled by the GridState.

When the Column is using default behaviour (not Templated), it works as intended. But as soon as you use a <Template> for the Column, the Locked state cannot be changed from the default/supplied value.

TLDR: Programmatically changing the Locked state of a column where the cell is templated will not change the locked state.

I have prepared two REPL examples. One for 3.7.0 as it is what we currently are using, and one for 4.0.1 as to prove that it still exists in the current itteration.

3.7.0

Imagine a Grid with two editable columns, which are separated by a few non-editable ones. In the standard use case, tabbing from the first editable column should jump over the non-editable columns, and the user should end up in the second editable column.

However, if the Grid uses virtual columns and the second editable column is not rendered, tab-to-edit will stop working.

The Blazor TelerikGrid component should support a dropdown column.  It should be exactly the same as the dropdown column in the Ajax grid.

https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/columns/column-types#dropdown

Grid with columns price1 and price2. Enter value in price1, switch to price2, enter value there, and editor is set to old value after async events finish.

The value entered in price2 is correctly set to the property, but the editor reverts to the previous value. If you escape edit mode of the cell, the value entered before the events finish will be shown.

On (fast) tabbing and entering values, this removes the first values entered before the async background events finish.

I tried reproducing the problem in REPL, but could not get the exact same behaviour. In our case no specific value is being set to price2, it just reverts.

How would you approach preventing the editor from being overridden by other cells' delayed events?

Using CheckBoxList filtering changes the filter menu for all columns. I would like to specify CheckBoxList only for certain columns, but that doesn't currently appear to be an easy option.

1) Leave as FilterMenuType "Menu" but implement a custom filter template for the columns I want. That would be the most obvious, but CheckBoxList is not a usable control on its own?

2) Or do the inverse, use FilterMenuType "CheckBoxList" and implement a custom filter template for all the columns where I don't want to use that. Seems like a lot of extra work to manually recreate default filters.

3) I guess I roll my own clone of the CheckBoxList control and use that like #1 on individual columns?

Any chance the CheckBoxList control could be publicly exposed for direct use?

I added a comment to this feedback post.  In this post, I made a comment on how to get Tab select working in a grid component for a combobox.

It would be nice if tab select was a parameter for any dropdown component and autocomplete. Maybe a parameter called "TabSelect"? It would need to fire before the grid component picks up the Tab key first in InCellEdit mode. 

If that was changed above, then the grid component could have the following:

Enter key to move down the list, and Shift-Enter keys to move up the list. Is there a way to do that currently, or could it be added?

Grid popup editing throws about parameterless constructor even when I use the OnModelInit event.

The inline and incell edit modes are still working.

The regression occurs in version 4.2.0.
