We would like to see this functionality:

Stacked Header like in https://blazor.syncfusion.com/demos/datagrid/stacked-header?theme=bootstrap4

Hi, I'm looking to reproduce visual behavior with the Blazor WASM Gird that we've already standardized on in our implementation of the KendoReact Grid component.

one of the things we're doing that i'm not seeing yet in the Blazor Grid docs is rendering a triple-dot icon in the column header that clicks down to show a custom menu... looking around, the closest thing i see so far is the Blazor Grid support for a "Toolbar" header... that would probably work as a path forward but I wanted to ask if i was missing anything else more similar? or perhaps eventual plans.

or is there any facility to custom render the column header ourselves?

i'm including a screenshot example of what we've settled on so far after several iterations

Thank you! this Blazor wasm direction you're supporting is fantastic =)

I have a grid that i use to display a number of different items with, some that have the need to display child or hierarchical grids, and some that don´t.

At the moment, all of the items show the "plus" button to expand the child grid, event though there is nothing there to show.

When a collection is null I think that the "plus" button to expand the hierarchical, or child grid, should be hidden. 

Or at least I should be able to hide that button manually by choice. 

Regards Magnus.

Issue - Filtering / Sorting on a column that is bound to a complex object fails to generate the proper OData string.

Example Grid Code, three columns, column 1 and 3 are bound to a complex class, column 2 just a string:

<TelerikGrid Data=@sysVars.Dtos Pageable="true" Sortable="true" FilterMode="Telerik.Blazor.GridFilterMode.FilterRow" PageSize="20" TotalCount=@sysVars.Count OnRead=@ReadItems>
        <GridColumns>
            <GridColumn Field=@nameof(SysVar.SysVarType.Name) Title="Type" Editable="false">
                <Template>
                    @{
                        var data = context as SysVar;
                        @data.SysVarType.Name
                    }
                </Template>
            </GridColumn>
            <GridColumn Field=@nameof(SysVar.Value) Title="Value">
                <Template>
                    @{
                        var data = context as SysVar;
                        var link = SysVarDto.FrontEndEditUrl(data.Id.Value);
                        <NavLink href=@link>@data.Value</NavLink>
                    }
                </Template>
            </GridColumn>
            <GridColumn Field=@nameof(SysVar.Hierarchy.Description) Title="Hierarchy">
                <Template>
                    @{
                        var data = context as SysVar;
                        @data.Hierarchy.Description
                    }
                </Template>
            </GridColumn>
        </GridColumns>
    </TelerikGrid>

The values bound to the grid are made up of a complex object.  For the sake of the example

 public class SysVar 
    {
        public string Value { get; set; }

        public Hierarchy Hierarchy { get; set; }

        public SysVarType SysVarType { get; set; }
}

public class Hierarchy 
{
      public string Description { get; set; }
}

public class SysVarType
{
      public string Name { get; set; }
}

Right now I know I can't have the Grid render SysVarType.Name, so I use a custom cell and everything works.  However, if I try to sort/filter on my complex columns, SysVarType or Hierarchy the resulting OData string that is generated is incorrect.

Example of what is should look like, from a Telerik Grid in my React application if I sort on the sysVarType column:

https://localhost:44335/odata/v1/SysVarOData?$count=true&$expand=sysVarType($select=name),hierarchy($select=description)&$skip=0&$top=20&$orderby=value,sysVarType/name

Same string generated by the Telerik Grid in Blazor

https://localhost:44335/odata/v1/SysVarOData?$count=true&$expand=sysVarType($select=name),hierarchy($select=description)&$skip=0&top=20&$orderby=Name

Note: I can't sort two columns at the same time, not a huge issue at this time.

What is failing is the $orderby= doesn't return sysVarType/name and only returns name, causing a 400 on my backend as the class SysVar doesn't have a name field.

I want to expand on another feature request regarding grid excel behaviour.

Like in excel moving into cell enables edit mode. Using arrow keys or enter key moves out of edit mode and do an automatic update of cell. Escape cancels the editing.

With Wpf you have can extend the grid behaviour in order to do things like moving to the beginning of first column of next row when you are on the last column of row and you press the right arrow / tab / enter key

Hello,

I'm trying the grid component and I'm able to add a row to the grid using the embbed editor. But I wanted to add an item externally to the list:

<button @onclick="@MyClick">Add item</button>

void MyClick()
{
    MyData.Add(new SampleData() { ID = 46, Name = "from click" });
    StateHasChanged();
}

The new line does not appear on the grid but if I add a second item through the embbed editor then I get the 2 items!

I also try to replace the List<MyData> by an ObservableCollection<MyData> unsuccessfully.

Thanks & regards,

Here is how this page looks on mac, multiple browsers: https://demos.telerik.com/blazor-ui/grid/grouping

Notice that the columns are misaligned.  I believe this is because the scrollbar isn't rendered on a mac if it is "disabled" (there is nothing to scroll). 

Probably the best solution would be for it to render like this on all browsers, but have the columns line up (get rid of the spacer in the end of the header row) as the 'empty' scrollbar is not attractive :)

Consider the following scenario:

<TelerikGrid Data="Animals" Sortable="true">
  <TelerikGridColumns>
    <TelerikGridColumn Field="Color"></TelerikGridColumn>
    <TelerikGridColumn Field="Breed"></TelerikGridColumn>
  </TelerikGridColumns>
</TelerikGrid>

@functions {
  public List<Animal> Animals { get; set; } = new List<Animal> { new Dog { Breed = "Sheepdog", Color = "Black" } };

  public class Animal { public string Color { get; set; } }
  public class Dog : Animal { public string Breed { get; set; } }
}

Everything renders fine for the grid until you attempt to sort by Breed, which results in the following exception:

Not sure what is going on under the hood here, but perhaps this could be fixed by looking at the type of the object, rather than the underlying list?    I'm aware that this can be fixed by changing the data source to List<Dog> , but I think this use case of using a base-class is useful for many dynamic scenarios (think dynamic columns, etc)

Hello!

The multiple selection functionality in the grid no longer works as expected.

The select check boxes doesn't seem to do anything and the only way to select something is when clicking on the actual row.

The problem is also present on your demo page.

I would like to request these features on the Blazor Grid:

• Add column pinning/freezing
• Add selectable column totals sum/min/max/count/avg functions and/or a way to define custom column totals calculations

Thanks.

Hi there, 

Is it possible to have multi-column headers for the data grid, like we have in Kendo grid. 

if so, what would be the ETA? 

Thanks,

Deepa

Please add an attribute to Blazor GridColumn which allows to easily align text horizontal in a GridColumn

e.g. <GridColumn Field="@(nameof(Item.Price))" Title="Price" HorizontalAlignment="Right" />

At least: Left, Right, Center

An autofit feature would be useful which sizes a column according to fit the current content exactly (with some space on the left and right ;-)

* autofit attribute for a column to automatically autofit the column

* autofit method on a grid column to issue autofit by code

Autofit for entire table (nice to have)

* autofit attribute on the grid element to automatically autofit all its columns (except those explicitely set to AutoFit="false")

* autofit method on a grid to issue autofit by code
