Hi, i have a grid with row filter.

1. I change filter operator from the relative button

2. I edit the search field column

The grid show me the correct results.

Now if i clear the search field column, the filter operator automatically reset to the default value and not keep the settings i choose in step 1.

You can reply the issue with the first example in grid documentation: https://www.telerik.com/blazor-ui/documentation/components/grid/overview

The filter operator must keep my initial settings

It's a bug? how to solve?

Thanks

I just get a spinning wheel when I bring up NuGet Package Manager and have the source set to Telerik.

If I select other package sources they load and display quickly.

Any suggestions?

I’m trying to build a custom filter for a column in the Telerik Grid. I’d like to have both the custom filter and the default filter available in the column's filter menu. I’ve managed to get the custom filter displaying and working correctly, but the default filter is not appearing in the filter menu for that column. I’ve attached the code — could you please help me figure out what’s missing or incorrect?

Many Thanks

Hi,

I've some TelerikCard components that host different other components but when using lets say the TelerikTimePicker then as soon as you try to input a time via keyboard it gets a red border and seems to invalidate the input.

When using the TelerikTimePicker outside in a simple div then it seems to work.

Also when using the popup to set the time it works. Only keyboard input seems to trigger some sort of validation.
When losing focus the timepicker resets to 00:00:00.

Here's the code of the razor page to replicate the problem:

<TelerikCard Width="20rem">
    <CardHeader>
        <CardTitle>Time Selector</CardTitle>
    </CardHeader>
    <CardBody>
        Startzeitpunkt<br>
        <TelerikTimePicker @bind-Value="@SelectedStartTime" Format="HH:mm:ss" Width="6rem" />
        <br>
        Endzeitpunkt<br>
        <TelerikTimePicker @bind-Value="@SelectedEndTime" Format="HH:mm:ss" Width="6rem" />
        <br>
    </CardBody>
    <CardSeparator></CardSeparator>
    <CardFooter>
        footer
    </CardFooter>
</TelerikCard>

@code {
    protected DateTime SelectedStartTime { get; set; }
    protected DateTime SelectedEndTime { get; set; }
}

I use the latest telerik blazor components 9.1.0 and VS 2022 17.14.9.

Maybe someone has a hint what's wrong with it.

Regards,
Thomas

I'm looking for something similar to this:

Need this for annotating and editing both bitmapped and vector based graphics related to an engineering applcation.

How do I set the TreeList filter through code?  So, can I put a value in the criteria field from code behind?

                <TelerikTreeList @ref=@TreeListRef
                                 Data="@Groups"
                                 SelectedItems="@SelectedGroups"
                                 IdField="@nameof(Group.Id)"
                                 ParentIdField="@nameof(Group.ParentId)"
                                 OnStateInit="((TreeListStateEventArgs<Group> args) => OnStateInitHandler(args))"
                                 Pageable="true"
                                 PageSize="@GroupPageSize"
                                 Height="100%"
                                 Sortable="false"
                                 SelectionMode="TreeListSelectionMode.Single"
                                 FilterMode="@TreeListFilterMode.FilterMenu"
                                 @bind-Page="@GroupCurrentPage"
                                 SelectedItemsChanged="@((IEnumerable<Gsi.Customer.Models.Group> m) => OnGroupSelected(m))">
                    <TreeListColumns>
                        <TreeListColumn Field="Name" Title="Group Filter" Expandable="true">
                            <Template>
                                @{
                                    var item = context as Gsi.Customer.Models.Group;
                                    <img height="32" width="32" src="@item.ImageUrl" />
                                    @item.Name
                                }
                            </Template>
                        </TreeListColumn>
                    </TreeListColumns>
                </TelerikTreeList>

I have a treelist with a checkbox for selection.  However, my list is long so I added pagination.  I help the user by pre-selecting a node and I need to display the page that exposes the first selected node.  How do I do this?
