So I have a grid with a subgrid.

Sometimes the subgrid has enough data rows that it seems to the user the grid is doing nothing when in fact tis still getting ready to display its subgrid contents.

I was wondering if there was a way to show the Loader object when these rows are taking a bit to show up?

Is there a way to disable text selection.

I tried adding this css class 

.disable-selection {
    user-select: none;
}

on the <TelerikGrid/> level but I can still highlight text.

Hello.

I need to cancel a user selection based on  some criteria.  Any idea?  Example, User choose a new item in the dropdownlist and after check something in OnChange event I want to keep the original selection.

                       <TelerikDropDownList Data="@infosEtapeMaitriseCategories"                        
                                         @bind-Value="@CurrentlyEditingEtapeMaitrise.tlkpEtapeMaitriseCategorieId"
                                     TextField="TextField" ValueField="ValueField"
                                     Enabled="@tlkpEtapeMaitriseCategorieIdEnabled"                                             
                                     Width="100%">

When I try the following I just get the underlining number: 343526.3

<ChartSeriesTooltip Visible="true">
                                <Template>
                                    @(string.Format("{0:C2}", (context.FormattedValue as object)))
                                </Template>
                            </ChartSeriesTooltip>

When I try, I get:

<ChartSeriesTooltip Visible="true">
                                <Template>
                                    @(string.Format("{0:C2}", (context.DataItem as object)))
                                </Template>
                            </ChartSeriesTooltip>

I am not sure what I am doing wrong here.

the class tis attached to:

public class MDRevNCostOverTime
        {
            [DisplayFormat(DataFormatString = "{0:C}")]
            public decimal Series1 { get; set; }
            [DisplayFormat(DataFormatString = "{0:C}")]
            public decimal Series2 { get; set; }
        }

How to disable window resizing (by default, the Window is resizable) of Popup Form Template (GridPopupEditSettings)

(similar to the Resizable="false" property for the TelerikWindow component).

Thank you for the help.

Hi,

ist there any "Selected" Event for the Editor? I would like to enable/disable custom Tools, based on Selection, like you do with the add/remove hyperlink button.

Thanks

I have the following TelerikListView.  When the user changes the TelerikTextBox Cidr value I want to handle the ValueChanged event however when I do this, I need to update the underlying model object manually.  I am stuck.  When the TelerikListView is in edit mode, either for a new element or for an existing element I can't figureout how to reference the element correctly in the ValueChanged event handler.  I know I need to update the model manually but I am not sure how.  Any hints?

<TelerikListView Data="@SubnetList" Width="700px" Pageable="true"

                 OnCreate="@CreateHandler" OnDelete="@DeleteHandler" OnUpdate="@UpdateHandler"
                 OnEdit="@EditHandler" OnCancel="@CancelHandler">
    <HeaderTemplate>
        <h2>Subnet List</h2>
        <ListViewCommandButton Command="Add" Icon="@FontIcon.Plus">Add Subnet</ListViewCommandButton>
    </HeaderTemplate>
    <Template>
        <div class="listview-item">
            <h4>@context.Cidr</h4>
            <ListViewCommandButton Command="Edit" Icon="@FontIcon.Pencil">Edit</ListViewCommandButton>
            <ListViewCommandButton Command="Delete" Icon="@FontIcon.Trash">Delete</ListViewCommandButton>
        </div>
    </Template>
    <EditTemplate>
        <div style="border: 1px solid green; margin: 10px; padding: 10px; display: inline-block;">
            <TelerikFloatingLabel Text="CIDR">
                <TelerikTextBox Id="Cidr" ValueChanged="@CidrValueChangedHandler" />
            </TelerikFloatingLabel><br />
            <ListViewCommandButton Command="Save" Icon="@FontIcon.Save">Save</ListViewCommandButton>
            <ListViewCommandButton Command="Cancel" Icon="@FontIcon.Cancel">Cancel</ListViewCommandButton>
        </div>
    </EditTemplate>
</TelerikListView>
@code {
    private List<Models.Subnet> SubnetList = new List<Models.Subnet>();

    protected override async Task OnInitializedAsync() 
        => SubnetList = await SubnetService.GetAllAsync();

    private void CidrValueChangedHandler(string theUserInput)
    {
        // manually update the model here 

        // calculate subnet properties here to help the user select size the subnet
        // correctly by selecting the number of bits in the network side of the mask
        //    # number of hosts, etc.
    }

    async Task GetListViewData()
        => SubnetList = await SubnetService.GetAllAsync();
}

Good Day,

I have been implementing drag&drop functionality between two Telerik Blazor grids using different data models. Using the documentation article as a reference below, I am able to get 2 models (derived from the same interface) to drag between 2 grids.

How to Drag and Drop Different Models between Multiple Grids - Telerik UI for Blazor

However, grid functions such as sorting and filtering start throwing errors, when unique fields are introduced per model. To re-produce, start with the demo code in the artcile and try and sort "Unique Field 1".  This throws an exception: "Unhandled exception rendering component: Invalid property or field - 'UniqueField1' for type: IParentSampleData". See screenshot attached.

This makes sense, but it's very limiting. My question is, if this can "worked around" in any way.

I have tried to intercept the "StateChanged" event. But as I still need to call gridObj.SetStateAsync(args.GridState), I cannot circumvent the issue. As per the error, I assume that these Grid methods use the interface definition and not the actual model instance to determine available properties for filtering & sorting, etc.

Is there somethig I am missing? Would anyone have any experience with this scenario and could point me in the direction of a "work around" if one exists?

Many thanks,
Peter
