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.

Hi, 

I am using a grid on a data structure that has nested properties inside. Previously, I was able to do this which worked fine: (notice the first 2 colums)

              <TelerikGrid Data="@PackedInfo.PackedParts" Height="100%">
                    <GridColumns>
                        <GridColumn Field=@nameof(PackedPart.Part.PartNo) Title="Part no" />
                        <GridColumn Field=@nameof(PackedPart.Part.PartDescription) Title="Description" />
                        <GridColumn Field=@nameof(PackedPart.UnitWeightG) Title="Substance Weight" />
                        <GridColumn Field=@nameof(PackedPart.FlashPointCentigrade) Title="Flash point" />
                        <GridColumn Field=@nameof(PackedPart.Pg) Title="PG" />
                        <GridColumn Field=@nameof(PackedPart.Qty) Title="PG" />
                    </GridColumns>
                </TelerikGrid>

I recently upgraded to the latest version (Telerik.UI.for.Blazor (2.29.0) and noticed that the first 2 fields are no longer displaying. I fixed this, by specifying the field names as string values:

               <TelerikGrid Data="@PackedInfo.PackedParts" Height="100%">
                    <GridColumns>
                        <GridColumn Field="Part.PartNo" Title="Part no" />
                        <GridColumn Field="Part.PartDescription" Title="Description" />
                        <GridColumn Field=@nameof(PackedPart.UnitWeightG) Title="Substance Weight" />
                        <GridColumn Field=@nameof(PackedPart.FlashPointCentigrade) Title="Flash point" />
                        <GridColumn Field=@nameof(PackedPart.Pg) Title="PG" />
                        <GridColumn Field=@nameof(PackedPart.Qty) Title="PG" />
                    </GridColumns>
                </TelerikGrid>

I have also tried using @nameof(Part.PartNo) but that didn't work either. Only providing nested properties as string values works. This should not be the intended behaviour i'm sure?

AutoFitting all columns should not leave blank space in the Grid, the last column should take the available space.

This functionality might be triggered by a setting a bool parameter to true. 

Hello,

The Grid header and data cells become misaligned if the user changes the page zoom level. The right padding of the Grid header area resizes, according to the zoom level, but the scrollbar width remains the same. This triggers the misalignment.

The problem disappears after browser refresh at the current zoom level.

I would like to set increase the searchbox width with a parameter.

ADMIN EDIT

Here is a CSS workaround:

<style>
    .custom-searchbox-width .k-grid-search {
        width: 50%;
    }
</style>

<TelerikGrid Data=@GridData Pageable="true" Height="400px" Class="custom-searchbox-width">
    <GridToolBar>
        <span class="k-toolbar-spacer"></span> @* add this spacer to keep the searchbox on the right *@
        <GridSearchBox />
    </GridToolBar>
    <GridColumns>
        <GridColumn Field="@(nameof(Employee.EmployeeId))" />
        <GridColumn Field=@nameof(Employee.Name) />
        <GridColumn Field=@nameof(Employee.Team) Title="Team" />
        <GridColumn Field=@nameof(Employee.IsOnLeave) Title="On Vacation" />
    </GridColumns>
</TelerikGrid>

@code {
    public List<Employee> GridData { get; set; }

    protected override void OnInitialized()
    {
        GridData = new List<Employee>();
        var rand = new Random();
        for (int i = 0; i < 15; i++)
        {
            GridData.Add(new Employee()
            {
                EmployeeId = i,
                Name = "Employee " + i.ToString(),
                Team = "Team " + i % 3,
                IsOnLeave = i % 2 == 0
            });
        }
    }

    public class Employee
    {
        public int EmployeeId { get; set; }
        public string Name { get; set; }
        public string Team { get; set; }
        public bool IsOnLeave { get; set; }
    }
}

When using the TelerikCheckBoxListFilter component in a FilterMenuTemplate, it does render a checkbox with a blank label, but selecting it does not generate a filter descriptor.

For reference, the built-in CheckBoxList filtering correctly filters null values.

GridCheckBoxColumn:  The check disappears when focus is on a editable cell.

I'd like to be able to enable the Column Chooser menu on just the Command Column and then keep all the other column menus as-is (I have a combination of various custom filter controls on them, so I don't watch to switch to the Column Menu)

When storing and restoring grid state, the selected page size is not included as part of that state currently, and needs to be stored seperately.

(When using GridPagerSettings, the user can select the page size based on inputs provided to PageSizes param. This selection is not synced and will revert to default each time the grid is loaded.

Hi, please expose a property in TelerikGrid where we can set the number of virtual columns to load in advance. A lot of times we would like to load data in advance for 5-10 columns left & right of the current viewport, so the user doesn't see empty columns while scrolling. This may apply to rows as well. It would be very helpful to have this property, please consider exposing it. Thank you.

============

The column Virtualization feature improves the Grid performance when it has a lot of columns. This does not include loading data on demand, but rather UI virtualization. All the data is retrieved and the performance optimization is achieved by rendering only the columns for the current Grid viewport. When the user scrolls horizontally the content for the other columns is rendered and while this happens, the cells appear empty. The requested parameter will control the number of columns that will be rendered in the current viewport but will not be visible until the user scrolls. Thus, the user will not see empty columns.

Hi, please expose the debounce delay as a property of TelerikGrid so we can set how soon virtualized columns are loaded after the user scrolls.

**Admin Edit**

This feature request requires research, and if such DebounceDelay parameter can work with good quality in all cases - it will be implemented. Additionally, we will revise the feature together with loading next set of columns if it will be applicable.

**Admin Edit**

I suggest adding a FieldExpression property to the GridColumn so a developer would not need to create view models and templates for simple transformations of the existing model's properties. The field expression would be used for filtering and sorting as well. Its type would be Func<T, object> or Expression<Func<T, object>>.

   <TelerikGrid Data="@Persons">
            <GridColumns>
                <GridColumn FieldExpression="@(p => p.FirstName + " " + p.LastName)" />
            </GridColumns>
        </TelerikGrid>
