I noticed Telerik Blazor grid is rendered into two tables. One for the headers and one for the contents.

My assumption is that Allyable Scan expects to find a th element inside the second table and it did not find any. Is my assumption correct? 

Element source:

<table role="grid" style="width: ;">

If you create a second Grid on the page, it will clear the SearchBox input value of the first Grid.

<p><TelerikButton OnClick="@ToggleSecondGrid">Toggle Second Grid</TelerikButton></p>

<TelerikGrid Data="@GridData">
    <GridToolBar>
        <GridSearchBox />
    </GridToolBar>
    <GridColumns>
        <GridColumn Field=@nameof(Product.ProductName) Title="Product Name" />
    </GridColumns>
</TelerikGrid>

@if (ShowSecondGrid)
{
    <TelerikGrid Data="@( new List<Product>() )">
        <GridColumns>
            <GridColumn />
        </GridColumns>
    </TelerikGrid>
}

@code {
    List<Product> GridData { get; set; }

    bool ShowSecondGrid { get; set; }

    async Task ToggleSecondGrid()
    {
        ShowSecondGrid = !ShowSecondGrid;
    }

    protected override void OnInitialized()
    {
        GridData = new List<Product>();

        for (int i = 1; i <= 5; i++)
        {
            GridData.Add(new Product()
            {
                ProductId = i,
                ProductName = "Product " + i.ToString(),
                UnitPrice = (decimal)(i * 3.14),
                UnitsInStock = (short)(i * 1),
                Discontinued = false
            });
        }
    }

    public class Product
    {
        public int ProductId { get; set; }
        public string ProductName { get; set; }
        public decimal? UnitPrice { get; set; }
        public short? UnitsInStock { get; set; }
        public bool Discontinued { get; set; }
    }
}

We are getting a problem with grid functionality after upgrading from 2.25 to 2.26. I have attached a test project. To see the problem:

• Run the attached solution
• Click on the "Tree List" menu item
• You will then see a grid at the top of the page
• On the first row, click into the text cell under "Column 2" (to the right)
• Now click into the next cell over at "Column 3"
• Now click again into that same cell
• You get the crash

We did not have this problem before version 2.26.

Just another note on this.

It appears that the presence of the checkbox columns causes the problem. Removing the checkbox columns causes the grid to work fine. Just having one checkbox template column in the grid causes the strange crash behavior in 2.26. Before 2.26, we had no problems with the checkbox templates impacting behavior.

Irrespective of the grid 'grouping' technique (manual or via AutoStateInit), the <NoDataTemplate> is not displaying correctly.

All other grids that are not using Grouped columns all format correctly (when no results available).

It looks like the built-in validation does not respect clearing the edit item through state.  If you remove invalid edit item through Grid State, the Grid stays in edit mode and the OnRowClick stops firing.

The case is similar when you try to clear an invalid InsertedItem through the Grid State - the Grid probably stays in Insert mode and some events are not firing (for example CUD events).

Hi,

I'm trying to set an empty column title

 <Telerik.Blazor.Components.GridColumn Field="@item.FieldName"
                                       Title=""
                                       Resizable="true"
                                       Width="@width">

I would expect it to show an empty header title but instead fieldName is displayed.

Here is the scenario and how to reproduce the issue:

1. A Grid with a horizontal scrollbar. All columns have explicit widths, according to requirements.
2. The first 3 columns are locked (frozen).
3. Make the frozen columns 1 - 3 smaller. Save the Grid state.
4. Refresh the page and restore the Grid state in OnStateInit.
5. Scroll the non-frozen columns to see how the frozen columns are positioned, according to their previous larger widths. Now there are gaps between these columns.
6. The reverse issue occurs if the frozen columns are expanded in (3). Then, after state restore they overlap.

If we enable grouping on a grid which has `FilterMode="Telerik.Blazor.FilterMode.FilterRow"` then we can no longer successfully get focus into any of the filter row edit controls.

Clicking on filter text input box (I think you need to do it a few times) causes a js error and does not put the text input focus into the filter text input.

JS exception is:

telerik-blazor.js:35 Uncaught TypeError: Cannot read property 'getAttribute' of null

I'm getting error for dynamic Grid InCell editing. Error is displayed on editing before calling UpdateHandler. It is observed for adding new row or editing any row. 

Error: System.ArgumentException: Instance property 'x' is not defined for type 'System.Dynamic.ExpandoObject' (Parameter 'propertyName')

I was not getting this error In previous version 2.21.0 on edit of a dynamic field. Getting this error after updating to new 2.23.0 version without any code change.

1. Use the code from the incell editing docs (https://docs.telerik.com/blazor-ui/components/grid/editing/incell)and monitor the server console 
2. Edit a name (row 3 and onward)
3. Press Enter

I expect OnEdit to fire, but only OnUpdate fires
