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.

The feature request is to be able to define different focused date for the calendar in the picker. The datepickers currently provide automatic focused date based on the selection:

- DateTime.Now if no selection is made

- Selected Date

Can the ability to define a height/width for the Filter component be exposed?

Width - I've noticed that if your Column names are to long names are cut off. I've used CSS to work around this.

Height - This isn't exactly a bug but if you populate enough "<FilterField/>" the dropdownlist will extend down past the bottom of the page.

It would be helpful if we can we can define more settings from the dropdownlists Or atleast make it so the dropdownlist will not go beyond the bottom of the page.

It seems I'm missing Height, MinHeight, and MaxHeight settings here. 

From what I can see, currently the only way to set the expanded items for a TreeList is through the state.

The main problem is that the state doesn't fire the OnExpand event, meaning that if you have a server loaded tree you need to make sure to load the data before each item is expanded. It also allows for duplicates in the 'ExpandedItems' if you don't check for duplicates before adding to it.

The TreeView has an 'ExpandedItems' parameter that can be bound which is a bit nicer than using the state, but from my quick test this also doesn't fire the OnExpand event.

My request is for one of the following to be added:

1. Similar to how you can set the 'HasChildrenField' or 'ItemsField' on the TreeList, allow a 'IsExpandedField' value to be bound (Should fire the OnExpand when changed if possible). This would be the simplest way allow bindable control over the expansion of items while also making it so we don't have to manage duplicates in the 'ExpandedItems' collection.
   
2. Expose a method to expand/unexpand rows. This would be different to manually changing the state as it would also fire the OnExpand event for each row expanded.
   
3. Similar to the TreeView, allow an 'ExpandedItems' to be bound. Preferably this would also fire the OnExpand event.

If you are in edit mode using InCell, clicking somewhere else inside or outside the Grid should fire OnUpdate if the item is valid. However, if you click on some customly added element in the Grid (e.g. button, icon, dropdown) this will not fire OnUpdate for a valid item.

In Incell edit, clicking anywhere besides the edited cell should fire OnUpdate for a valid input.

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.

Currently, you can split the TelerikForm into multiple columns via the Columns parameter. These columns will have equal widths. I would like to have the ability to define custom width per column.

You can use the following code snippet as a workaround with some considerations:

• The k-grid-cols-2 class is a dynamic one. The "2" segment maps to the number of the columns defined via the Columns parameter exposed for the <TelerikForm>
• If there are more/less than two columns, you should change the values for the grid-template-columns accordingly.

<style>
    .non-equal-columns .k-form-layout.k-grid-cols-2 {
        grid-template-columns: 71% 28.5%;
    }
</style>

@using System.ComponentModel.DataAnnotations

<TelerikForm Model="@person" ColumnSpacing="25px" Columns="2" Class="non-equal-columns">
    <FormValidation>
        <DataAnnotationsValidator></DataAnnotationsValidator>
    </FormValidation>
    <FormItems>
        <FormGroup LabelText="Personal Information" ColumnSpacing="15px">
            <FormItem LabelText="First Name" Field="@nameof(Person.FirstName)"></FormItem>
            <FormItem LabelText="Last Name" Field="@nameof(Person.LastName)"></FormItem>
            <FormItem LabelText="Age" Field="@nameof(Person.Age)"></FormItem>
            <FormItem LabelText="Email" Field="@nameof(Person.Email)"></FormItem>
        </FormGroup>
        <FormGroup LabelText="Employee Information" Columns="2" ColumnSpacing="15px">
            <FormItem LabelText="Company Name" Field="@nameof(Person.CompanyName)"></FormItem>
            <FormItem LabelText="Position" Field="@nameof(Person.Position)"></FormItem>
        </FormGroup>
    </FormItems>
</TelerikForm>

@code {
    public Person person { get; set; } = new Person();

    public class Person
    {
        [Required(ErrorMessage = "The First name is required")]
        public string FirstName { get; set; }
        [Required(ErrorMessage = "The Last name is required")]
        public string LastName { get; set; }
        [Range(18, 120, ErrorMessage = "The age should be between 18 and 120")]
        public int Age { get; set; }
        [Required]
        [EmailAddress(ErrorMessage = "Enter a valid email")]
        public string Email { get; set; }
        [Required]
        public string CompanyName { get; set; }
        [MaxLength(25, ErrorMessage = "The position can be maximum 25 characters long")]
        public string Position { get; set; }
    }
}

As an extension to a context menu a radial menu control would be a nice addition.
