Hi

I've put the grid inside a modal window

All works but I cannot get the ref to the grid: I get null.

Is it correct ?

I need to put a filter by code when I show the window modal with grid

tnx

I use a MVVM approach to populate the Grid. The rows are actually viewmodels keeping state. They have no parameterless constructor, they are created by factory methos using injected services. The Grid creates the item before assigning it to the event args passed to the handler method. 

In my case "No parameterless constructor defined for type '...' is thrown. How can I have control on the creation of my row models?

After upgrade to 2.10.0, the ComboBox control with OnRead event, I get the error:

Uncaught (in promise) Error: System.ArgumentException: There is no event handler associated with this event. EventId: '38'. (the number differs between errors)
The page "blinks" and the control fills with an empty Guid (SelectedPersonId type)
The post to the server is performed correctly
This worked with 2.9.0

js:
<script src="https://kendo.cdn.telerik.com/blazor/2.10.0/telerik-blazor.min.js" defer></script>

razor:
<TelerikComboBox Data="PersonSearchResult"
OnRead="@SearchPersons"
Filterable="true"
TextField="FullName"
ValueField="Id"
@bind-Value="SelectedPersonId"
Width="400px">
</TelerikComboBox>

and cs:

private async Task SearchPersons(ComboBoxReadEventArgs args)
{
if (args.Request.Filters.Count > 0)
{
var filter = args.Request.Filters[0] as FilterDescriptor;
var search = filter.Value.ToString();
if (search.Length >= 2)
{
PersonSearchResult = await Post<List<PersonModel>>("api/person/person-search", search, true);
}
}
}

Hi

Any ideas how I can create a Modal Login Window on startup?

thx in advance

Any plans to add a Kanban board component similar to this?

Hello,

is it possible to pre-select the very first row in Grid in SelectionMode="GridSelectionMode.Single"? I need to do that by default when the Grid displays the very first time. I have second grid that based on this selection. I have already implemented the proper way of populating the second Grid and now just need to display display the first row selected.

Thanks.

The ComboBox control does not appear to be refreshing/updating when the underlying list that it is bound to is updated. Some sample code to replicate this is:

@page "/"
@using Telerik.Blazor;

<TelerikComboBox Data="@ComboValues" Value="@SelectedValue"  ValueChanged="@((string v) => ComboBoxSelectionChanged(v))" >
</TelerikComboBox>

@code {
    List<string> ComboValues = new List<string> { "One", "Two", "Three", "Four", "Five" };

    string SelectedValue = null;

    void ComboBoxSelectionChanged(string v)
    {
        ComboValues.Remove(v);
        ComboValues.Add("New " + v);

       SelectedValue = null;
    }
}

Keep in mind this is overly simplistic but does demonstrate what isn't working as expected.

I would expect in this case for the selected entry to be removed from the ComboBox and replaced with "New {Selected Entry}";

I had this working fine relatively recently but started updating my code after upgrading to version 2.10.  Now i can't tell for sure if this is a bug introduced in version 2.10 or if i just made a change that broke things.

Any feedback would be greatly appreciated.

Thank You

The html in bold is generated by the Menu control for a menu item, the non-bold code is from my menu item template.

The k-link / k-menu-link styles provides the mouse over and cursor effect.

<li class="k-item k-menu-item telerik-blazor"
data-id="e5bda03c-693b-4a70-9310-75977f58d39a" role="menuitem"
aria-live="polite" tabindex="0" aria-label="Paste">
    <span class="k-in k-link  k-menu-link   ">
        <span class="lt-menu-item lt-disabled">
            <img src="EditPaste.svg"><span>Paste</span>
        </span>
    </span>
</li>

I'm trying to create a disabled menu item, but I realy need to style the k-menu-link span otherwise the effect is not on the full menu item (see image).

Any thoughts on how to do this, or would it be possible to provide a property that allows a style to be injected into the  <span class="k-in k-link  k-menu-link   ">

When a menu is shown I need to be able to enable disable the sub menu items, so I need to hook an expanding event before the sub menu is rendered.

Is there any plan to add an OnExpanding event that is raised before the sub item is expanded?
