Ok I have a grid with many pages and a total of say 1million plus rows!

User filters this grid down to say 7000 rows.

When I click the export all button it will export the rows they filtered. Alls good.

But when they export the whole dataset I have to intercept that to do the export myself and email them a link to it.

My issue is I cant seem to find a way to figure out how many rows are in the filtered version.

So currently I have: ( in the async Task gridRpt_OnBeforeExcelExport(GridBeforeExcelExportEventArgs args) )

If the grid.count > 1000000

then go do my email export procedure

ELSE do the grids default export.

Problem is when the grid is filtered That grid.count is still the big dataset count not the filtered count.

How do I know the filtered count and if that filtered count is still over 1mil how to I export only that filtered set?

Hope that makes sense.

Thanks

With ChartCategoryAxes, is it possible to label the group and then each column within it? For example, https://blazorrepl.telerik.com/QdbaPgbU17q4epgO21:

1. We have tried to use ChartCategoryAxisLabel templates. But without HTML to enable styling it is difficult to space the elements evenly.
2. We have tried adding an invisible series at the top of the stacked series with a label, but on dark backgrounds the invisible series is revealed on hover. We can use brittle CSS selectors to hide the hover but ideally our label would be beneath the chart, within the axis. 

So we are building a component comprised of a high number of child components (think of a page with lots of controls on it). Ideally I want to use the TelerikTooltip for every child control component to display a tooltip on hover. However when we get above 140 child components the initial load performance of the ui gets significantly slower.

I am testing with a baseline of 500 child components and using the TelerikTooltip delays the render by about 13 seconds when compared to my own attempts at a tooltip (or not using it at all).

Are there any known performance tricks for the TelerikTooltip or anything in the pipeline for performance improvements with the TelerikTooltip?

Code snippet below where ComponentVM.ControlVMs has 500 objects:

foreach (IControlVM nextControl in ComponentVM.ControlVMs)
    {
        ControlName = nextControl.FormControlVM.FormControl.GetType().Name;
        <TelerikTooltip TargetSelector=".tooltip-target" Class="menu-tooltip" />
        
        <div style="position:absolute; 
                   z-index:@nextControl.FormControlVM.ZIndex;
                   border-radius:2px; border-width:2px; border-color:red; 
                   width:@string.Format("{0}cm", nextControl.FormControlVM.Width); 
                   height:@string.Format("{0}cm", nextControl.FormControlVM.Height);
                   left:@string.Format("{0}cm", nextControl.FormControlVM.CanvasLeft);
                   top:@string.Format("{0}cm", nextControl.FormControlVM.CanvasTop);
                   overflow:hidden;">

            @if (ControlRazors.ContainsKey(ControlName))
            {
            Dictionary<string, object> controlParams = new Dictionary<string, object>()
            {
                {nameof(ComponentVM), nextControl}
            };
                <DynamicComponent Type="ControlRazors[ControlName]" Parameters="controlParams" />

            }

            </div>
    }

If you use the Blazor repl link below and make the dimensions of the signature pad relatively large and you draw two lines in quick succession it sometimes doesn't draw the second line correctly.

For example, if I make the width 1000px and the height 400px (or more) and attempt to use my mouse to write my own name which starts with a D, I can draw the vertical line first and if I draw the curved line to complete the D too quickly it will sometimes draw a straight line from start to finish rather than following the curve that I made with the mouse. It's like there's some sort of lag occurring before you can draw a second line. If I wait a couple seconds before drawing the second line it works. The larger you make the signature pad the more pronounced this issue is. You can also see this if you use your mouse to draw several random lines in quick succession.

When the dimensions are smaller, say 500px x 200px it mostly works okay, but if I have a user running a big ipad pro then having to limit the signature pad size like that isn't going to work very well. Is there any way to resolve this?

Hi,

Is there a way of having a timespan (or duration) component in Blazor at all, like the one mentioned here for Xamerin:

https://www.telerik.com/blogs/choose-time-duration-telerik-timespan-picker-xamarin

Apologies if I have missed it in the docs.

Regards,

Rawden.

Hi - can someone please point me towards definitive documentation for all the Telerik CSS classes and how they work with the Telerik UI for Blazor components - and for other html elements too? I don't mean documentation on how to install/configure the actual styles/style sheets - I mean documentation on the actual css classes themselves.

(I'm using the default theme - but it would be good to have CSS docs for the other themes too.)

For example, I see examples that use classes like "k-d-flex-col k-align-items-center k-justify-content-evenly" ... I can guess what they do from the context, but it would be nice to see some nicely organized documentation on these and other "k-..." classes and how to use them.

Thanks,

Tim.

Hi there

We have a Scheduler with three resources defined which is working as expected. I've removed a bunch of tags for simplicity:

<TelerikScheduler
    Data="@Flights"
    AllowCreate="true"
    AllowDelete="false"
    AllowUpdate="true"
    OnEdit="@Edit">
    <SchedulerResources>
        <SchedulerResource
            Field="@nameof(Flight.SquadronEntityRowId)"
            Title="Squadron"
            Data="@_allSquadrons"
            TextField="@nameof(Squadron.Name)"
            ValueField="@nameof(Squadron.SquadronEntityRowId)"
        />
        <SchedulerResource
            Field="@nameof(Flight.AircraftEntityRowId)"
            Title="Aircraft"
            Data="@_allAircraft"
            TextField="@nameof(Aircraft.TailFinId)"
            ValueField="@nameof(Aircraft.AircraftEntityRowId)"
            ColorField="@nameof(Aircraft.Colour)"
        />
        <SchedulerResource
            Field="@nameof(Flight.AircraftType)"
            Title="Aircraft Type"
            Data="@SelectedAircraftTypes"
            TextField="@nameof(AircraftType.Name)"
            ValueField="@nameof(AircraftType.AircraftTypeEntityRowId)"
            ColorField="@nameof(AircraftType.Color)"
            />
    </SchedulerResources>
    <SchedulerSettings>
        <SchedulerGroupSettings Resources="@(new List<string> { nameof(Flight.SquadronEntityRowId) })" Orientation="@SchedulerGroupOrientation.Horizontal"></SchedulerGroupSettings>
    </SchedulerSettings>
</TelerikScheduler>

As you can see, we have grouping defined on one of the resources. This seems to work in the UI (aircraft and groups redacted for client confidentiality):

However, despite having set AllowCreate="true", when doubling clicking an empty slot the OnEdit event doesn't fire.

If I clear resource grouping however, double clicking then fires the edit event as expected:

Can someone please help us understand why creating new appointments when resource grouping is on isn't working? Is this intended behaviour?

Cheers,

Paul

I'm getting the below error as I'm trying to update to .net8.  I've also created a bare minimum blazor web application with the same results. I'm not finding any Telerik .net8 documentation related to Blazor UI so I'm not sure what is missing? Is not.8 not currently supported?

"Unhandled exception rendering component: A Telerik component on the requested view requires a TelerikRootComponent to be added to the root of the MainLayout component of the app. Read more at: https://docs.telerik.com/blazor-ui/getting-started/what-you-need#project-configuration."

I am working with a grid that uses paging.  One of the options I expose to the user is to allow for a page size of "all" to show all records.  When selected, it can take the grid 10-20 seconds to display all those records, but there is no indication to the user that there is processing going on.  I saw another ticket that mentioned using the PageSizeChanged & onRead event to display a loading image, but that loading image is still delayed.

Is there another way to achieve the goal of showing a loading spinner when the grid is doing larger operations.  Paging, filtering, etc...

Thanks in advance
