I would like to be able to do something like

<GridCommandColumn>
@{
context as MyModel;
if(context.ShowButton)
{
<GridCommandButton>Todo</GridCommandButton>
}
}
</GridCommandColumn>

ADMIN EDIT

See the thread below for a way to implement this right now with your own buttons in a "regular" column and the grid state.

Hi there,

currently the grid component does not provide a feature to set a specific position in virtual scrolling mode.

My team has currently implemented a workaround via javascript interop call to set a specific position. The workaround basically calculates the "scroll value" (we reverse engineered this value by looking at the Telerik js code) and passes it to the jQuery scrollTop() function. This results in an update of the scrollbar which in return triggers the OnReadItems event where we fetch the items based on the given skip and take values.

This workaround does not seem to work in all cases and is somewhat unreliable hence i'm requesting an official feature to set a specific position without the javascript hack.

What do you say?

Grid with Checkbox Column throws the following error when placed inside EditForm:

InvalidOperationException: Telerik.Blazor.Components.TelerikCheckBox`1[System.Nullable`1[System.Boolean]] requires a value for the 'ValueExpression' ValueExpression is provided automatically when using 'bind-Value'.

The issue can be reproduced using the Filter From Code -> FilterMenu code snippet provided here:
https://docs.telerik.com/blazor-ui/components/grid/filtering#filter-from-code

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.

I would like to be able to set Min Width parameter to a Grid Column. The behavior I expect to see is:

• The Grid Column with set Min Width will take all the available space on large screens
• On smaller screens it will shrink but no more than the set min width (e.g. 100 px).

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

I would like to be able to edit both Date and Time in Grid editing mode.

Telerik edit: Possible since version 3.1.0 with through the column EditorType parameter.

Based on row values, I want to style the entire row.

It could perhaps be exposed through something like a "<RowDescriptor>" element inside the <GridColumns>

//ADMIN EDIT: We plan to extend this item so that it includes not only row styling, but also the ability to add CSS classes to the cells, without having to use the Template.

I would like to be able to customize the title in Editing Popup. 

<AdminEdit>

We plan to expose the following customization options:

• Title,
• Width
• Height
• MaxWidth
• MaxHeight
