Combobox Value not populate on load

I have a simple combobox where the value is not populated on load:

@SelecteValue is a string

@SourceColumns is an ObservableCollection<String>

If I switch it to a drop down list, the item is selected, however I need to be able to have custom values.

This seems pretty straight forward, and I am thinking I am missing something minor?

Data Grid - Put all rows in edit mode

I am trying to use the data grid for mapping a source to a destination. I would like to have a grid toolbar command that puts all rows in edit mode and then while in edit mode either disable or hide the button. Is this feasible if so, any guidance on how to do this?

[Solved] Maximized window fills entire scrollable area instead of the viewport

I have a scrollable page that includes logic to show a Telerik window control. I have the window height set by default to 600px and I have included the default maximize action. The content of the Window may or may not be scrollable as well.

When I maximize the window control it fills the entire scrollable area rather than just the current visible area.

Any thoughts on what I might be doing wrong or if this is how the control is supposed to work?

Thanks,

Greg

[Solved] TreeList Editor Template

Hi,

Is it possible to specify different editor templates for different levels in hierarchical data?

What I am trying to do is to build a hierarchical structure for grouping items. The list of items is specified so, in the grouping hierarchy, I want to select an item as the child element of the lowest grouping level rather than typing the name of the item and resolving if it exists. I thus want for the lowest level, to have a combobox rather than an editbox. The data items presented in the treelist have a property to bind to.

Thanks for any suggestions.

[Solved] Telerik Grid Expand Button Tooltip?

Hi,

Is there a tooltip option to add for the expend plus button on the left of a telerik grid row. Several of my clients have wondered if I could do this? Is there a function already in the Telerik Blazor Grid component? If not, are there any examples of someone attempting this on github? My clients have employees which they believe this option/concept would be very helpful.

Window positioning glitch when Draggable=true and main page is scrolled up

I'm noticing that the window will shift down when I click on the window title (e.g. when I want to move the window). It only happens if I have scrolled my main page up. As a matter of fact, the window will shift down exactly the same distance that I've scrolled my main page. The shifting will occur repeatedly as well. Each time I click on the window title, it shifts down until it's completely disappeared. At that point I'm stuck because I can't close the window. Looks like the calculation that is computing the top coordinate of the window isn't correctly accommodating the scroll position of the main page.

Telerik Combobox loses it's binding grid when pressed update

Hello,

I want to use a combobox in a telerik grid, I'm succesfully able to bind and display the data in the combobox as well.

however when I select a value from the combobox and press the update button, I get out of the edit mode and the combobox

value goes back to null. (placeholder)

here is a simplified version of my models

  public class PageControlsM
    {

        [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }

        public string ControlCode { get; set; }

        [ForeignKey("ControlCode")]
        public  ControlTypes ControlTypes { get; set; }

    }

public class ControlTypes
    {
        [Key]
        public string Code { get; set; }
        
        public string ControlName { get; set; }

        public string HtmlCode { get; set; }
    }

and this is my grid implementation:

 <TelerikGrid Data="@PageControlList"
                  Height="auto"
                  Pageable="true"
                  Sortable="true"
                  Reorderable="true"
                  Resizable="true"
                  PageSize="5"
                  EditMode="GridEditMode.Popup">
            <GridToolBar>
                <GridCommandButton Command="Add" Icon="add">Yeni Kontrol Ekle</GridCommandButton>
            </GridToolBar>
            <GridColumns>

                <GridColumn Field=@nameof(PageControlsM.ControlCode) Width="100%" Title="Kontrol Turu">
                    <EditorTemplate Context="controlMContext">
                        @{
                                if (controlMContext is PageControlsM controlM)
                                {
                                <TelerikComboBox Data="@ControlTypesList"
                                                 TextField="ControlName"
                                                 ValueField="Code"
                                                 Width="90%"                                                
                                                 @bind-Value="controlM.ControlCode"
                                                 Placeholder="<Seciniz>"
                                                 ClearButton="true"
                                                 Filterable="false">
                                </TelerikComboBox>
                                }
                        }
                    </EditorTemplate>

                </GridColumn>

                <GridCommandColumn Width="100%">

                    <GridCommandButton Command="Edit" Icon="edit">Edit</GridCommandButton>
