When the page is printed, the Grid is extended down onto multiple sheets of paper. This is because the Grid is large. The issue I am having is that the column headers are not repeating on each printed page. This makes the grid very hard to read. Is there a setting that can force the column headers to print on each printed page?

For Excel export, this depends on: https://feedback.telerik.com/document-processing/1356293-print-titles.

I want to add a custom sort comparer but I don't want to perform the whole sorting manually through the OnRead event.

Please allow adding custom expressions that will be applied to the query that the DataSource package does for easier customizations of the data operations.

Hi!

When i set GridCommandButton 

<GridCommandButton Command="Save" Icon="save" ShowInEdit="true">Save</GridCommandButton>

in a Grid component, I always get a Button with a label "Update". How can I change this? 

Thank you!

I localize the names of my columns in the models. This works for the root-level model I bind to the grid, but using nested (navigation) properties does not let them pick up the title.

ADMIN EDIT

A sample project is attached that showcases the localization of the displayname attribute, and how that works for the main model. Since it does not work for the nested models, a small helper method to extract the required resource manually is added to the Title parameter of such a column.

A nice feature would be frozen Group Rows.

So if you grouped your data in the Grid and scroll. The Group should stick underneath the header.

As an example look here: https://www.ag-grid.com/angular-data-grid/grouping-sticky-groups/

I want to use a multi-checkbox filter with ExpandoObject in Grid.

If a Grid column is bound to a nullable bool field and some of the data source records have null values for that field they are not displayed, the Grid cells appear empty.

It would be nice if the Grid displays some text for the null values, for example just "null".

I have a Grid with numerous columns and I am using inline editing. When in edit mode, I'd like to add custom content to each cell - for example, a validation error message from server validation.

To achieve that, I have to use EditorTemplate. However, I want to keep the default editor because I'd like to avoid having to add the relevant control for every single cell each time I add a new Grid.

Consider the following example. It will trigger AmbiguousMatchException, because reflection discovers two SpecialProp properties.

<TelerikGrid TItem="@GridModel"
             Data="@GridData"
             AutoGenerateColumns="true">
</TelerikGrid>

@code {
    List<GridModel> GridData { get; set; } = new();

    protected override void OnInitialized()
    {
        for (int i = 1; i <= 3; i++)
        {
            GridData.Add(new GridModel()
            {
                SpecialProp = i,
                Text = "Text " + (i * 111)
            });
        }
    }

    public record GridModel : Base1 { }

    public record Base1 : Base2
    {
        public new decimal? SpecialProp { get => base.SpecialProp / base.HelperProp.GetValueOrDefault(1); set => base.SpecialProp = value.HasValue ? (int)(value.GetValueOrDefault() * base.HelperProp.GetValueOrDefault(1)) : null; }
    }

    public record Base2
    {
        public int? SpecialProp { get; set; }
        public string Text { get; set; }
        public int? HelperProp = 10;
    }
}

Why not replace

private PropertyInfo FieldPropertyInfo => ContainerGenericArgument?.GetProperty(Field);

with something like

PropertyInfo FieldPropertyInfo = ContainerGenericArgument?.GetProperties().FirstOrDefault(p => p.Name == Field);

with the possibility to cache the result from GetProperties()?

Does the Blazor grid have any support for any or all queries on sub-property collections? I would like to have the grid OnRead be able to generate a query against a sub-entity collection.

E.g.

GET serviceRoot/People?$filter=Emails/any(s:endswith(s, 'contoso.com'))

From what I can tell the Column.FieldName property only will generate a valid query for scalar properties. Is there any way to make this work?

Given the Northwind OData sample https://demos.telerik.com/kendo-ui/service-v4/odata. I would like to display a grid of all customers. In the grid, I would like to have a column that provides filtering for the orders shipper column as in the query below.

https://demos.telerik.com/kendo-ui/service-v4/odata/Customers?$expand=Orders&$filter=Orders/any(d: contains(d/Shipper/CompanyName,'Speedy Express'))

There does not seem to be a way for the in-built filter mechanism to use a lambda and it seems like there should be.

Expose GroupableSettings with an option to specify whether to render the group footer. The possible values should be always (like current implementation), or when the group is expanded. An example (just for demonstration) api would be:

```

<GridSettings>

<GridGroupableSettings Footer="@GridGroupableFooterVisible.Always | @GridGroupableFooterVisible.Expanded"></GridGroupableSettings>

</GridSettings>

```
