Telerik input components inside EditorTemplate render the whole grid on each keystroke

<AdminEdit>

As a workaround, you can use the standard Input components provided by the framework together with a CSS class that would visually make them like the Telerik Input Components. An example for the TextArea:

<InputTextArea class="k-textarea" @bind-Value="@myValue"></InputTextArea>

</AdminEdit>

Problem:

Grid exports columns as 0 width unless Grid column widths are specified in px.  This is a terrible experience for users, and specifying grid width in px is terrible when you have users that can be using phones or 4k screens.  Managing Grid for different screen sizes is already hard enough! 

Solution 1: (Good)

The grid should export a default (64px) width for columns that aren't specified in px. Inexperienced Excel users are lost when columns are collapsed, but can easily resize columns as needed when each one is visible!

Solution 2: (Better)

Calculate a width - like [(rem value)*10]px. Even if it isn't perfect it will go a long way to creating something visually pleasing on initial open in Excel.

OnChange and OnBlur event for editors (TelerikTextBox, NumericTextBox, and others) is not fired in InCell edit mode with Tab key.

We often have grid data with a widely varying quantity of cell content from row to row. We usually present this with constant row height initially to have as much row overview as possible at a glance.

Grabbing the row divider line and individually make it larger or even double click on it to fit the size would be very useful for users.

It would be nice if it was possible to have a grid and have already in a cell the value of 1 and somebody want's to add 4 to it he doesn't have to calculate but could just type 1+4 and the answer (5) would be saved to the grid.

I have a Grid and if the initial validation fails for a certain cell and the user edits a cell with a valid value on the same row the editing freezes. 

<AdminEdit>

As a workaround, you can provide valid initial values for all cells in the Grid.

Using the following code to allow the user to select rows in the grid

<GridCheckboxColumn SelectAll="true" Locked="true" />

When using the Grid Export to Excel, there is no facility for the export to only use the rows selected by the user

<GridExport>

     <GridExcelExport FileName="Export File" AllPages="@ExportAllPages" />

</GridExport>

Hi,

Is it possible to drag grid row to another page on the same grid? 

thanks,
Irina

ADMIN EDIT

A sample reproducible is attached.

The issue stems from the inability of the System.Text.Json serializer to work with fields of type "Type" and the filter descriptors have such a field to denote the type of the column. Whether it will be possible for the grid to work around needs to be researched in more detail, because the limitation comes from the framework.

Might be the same problem as the following thread that also offers a few workarounds one can consider: https://feedback.telerik.com/blazor/1505237-set-deserialized-grid-state-in-onstateinit-handler-cause-error-on-open-filter-menu-of-column-on-ui

The documentation for the GridToolBar here describes Add, but ExcelExport is also seen in the demos:  https://docs.telerik.com/blazor-ui/components/grid/toolbar#built-in-commands

I imagine there are other built-in commands that are valid in the GridToolBar as well.

When the Grid has a non-grouped column at first position, there is a missing left border in an adjacent cell on the second line of the header area.

First reported in:

https://www.telerik.com/forums/multi-column-line-in-grid-occasionally-missing

Possible workarounds:

• Move the non-grouped column to another position.
• Wrap the non-grouped column in its own group.

Test page to reproduce:

(Uncomment the group column to use the second workaround from above.)

<TelerikGrid Data="@Data">
    <GridColumns>
        @*<GridColumn Title="Title">
        <Columns>*@
            <GridColumn Field="ID" />
        @*</Columns>
        </GridColumn>*@
        <GridColumn Title="Group">
            <Columns>
                <GridColumn Field="Name" />
            </Columns>
        </GridColumn>
    </GridColumns>
</TelerikGrid>

@code {

    public List<GridItem> Data { get; set; } = new List<GridItem>() {
        new GridItem() { ID = 1, Name = "Name 1" }
    };

    public class GridItem
    {
        public int ID { get; set; }
        public string Name { get; set; }
    }
}
