I have a grid with an Excel export.  It can take some time so I want to show a Notification at the start and end of the process using OnBeforeExport and OnAfterExport.  However both Notifications show at the same time.  I have reproduced the issue, attached.  Despite the 5 second delay being in OnAfterExport, neither Notification shows until after the delay and the Excel download.

Any ideas?

Hello,

I want to change the background color of TelerikTooltip which is displayed inside a TelerikGrid in blazor. 

I have tried following two examples but they do not seem to work for tooltips in the grid.

            <GridColumn Field="ABC" Title="Title" Width="15%">
                <HeaderTemplate>
                    <span class="k-column-title k-column-title-word-break">
                       Column Title
                    </span>
                </HeaderTemplate>

Hello,

we are currently evaluating Telerik for use in a new application. One major hurdle we are facing at the moment are key bindings. The application we are working on contains quite a bit of shortcuts as it aims at power users and key bindings are important for the efficiency of the workflows. The main component we are using is the TreeList, and one basic use case would be to expand and collapse all items in the TreeList with "*"/"-".

I read the forum articles about introducing keybindings to other components by wrapping the component in a div and using onkeydown on the div. That does not work with TreeList however (as I suspect the TreeList captures key events itself). I suspect using JS Interop might be the only option we have, but I just wanted to check if I am missing anything obvious.

Thank you,

Michael

I have put an example where Field argument cannot fulfil what I need to do. 

The Column names and Field names are only discovered at runtime.

I can get the values to be displayed as I want using the <Template> element/component however I cannot grouping or sorting on these columns. 

<TelerikGrid Data="@simplePropertiescollection" Height="500px"
   Sortable="true" 
   Groupable="true"
   Resizable="true" 
   Reorderable="true">
   <GridColumns>
      <GridColumn Field="@(nameof(SimpleProperties.Name))" Title="Name" />
      @foreach (string prop in PropColumns)
      {
         <GridColumn FieldFunc = "(v) =>v.GetProps(prop)" Title="@prop">
            <Template>
               @{
                  // FieldFunc would replace the code below
                  string text = (context as SimpleProperties)?.GetProp(prop);
               }
               @text
            </Template>
         </GridColumn>
      }
   </GridColumns>
</TelerikGrid>

@code
{

   List<SimpleProperties> simplePropertiescollection = new List<SimpleProperties>();

   List<string> PropColumns { get; set; } = new();

   public class SimpleProperties
   {
      public string Name {get; set;} 

      public List<SimpleProperty?>? Properties { get; set; }

      public string? GetProp(string name)
      {
         return Properties.FirstOrDefault((SimpleProperty o) => o?.Name == name)?.Value;
      }
   }
   public class SimpleProperty
   {
      public string? Name { get; set; }

      public string? Value { get; set; }
   }
}

I use TelerikDateTimePicker and clients of my application send me a lot of issues with TelerikDateTimePicker.

1). If user types in values (date and time) quickly, user will be redirected to the end of input field e.g. type in year 2023 as fast as possible -> only one or two first digits will be filled, other digits will be typed in the end of the field




2) After user manually enters month, year is not selected automatically. Users want the same behaviour as we have with day, year, hours, minutes:

3)  After user finishes entering all valid values Date & Time and clicks outside the input field (TelerikDateTimePicker), all entered will be removed.

I use code like:

<label for="selected-date">
    TelerikDateTimePicker for enter Date and Time
</label>
<TelerikDateTimePicker 
    @bind-Value="@SelectedTime"
    Min="@Min" Max="@Max"
    Format="dd MMM yyyy HH:mm 'Z' (UTC)"
    Placeholder="dd MMM yyyy HH:mm 'Z' (UTC)"
    Id="selected-date"/>


@code {
    DateTime? SelectedTime = null;
    DateTime Min { get; set; } = new(1900, 1, 1, 0, 0, 0);
    public DateTime Max { get; set; } = new(2099, 12, 31, 23, 59, 59);
}

I also tried to use some combinations of TelerikDateTimePicker properties:

AllowCaretMode="true"
AutoCorrectParts="true"
AutoSwitchParts="true"

but this only made the behaviour worse

Hi, as you can see from the sample below, i would like to edit a cell from row click (in addition to click on the editable cell), but if i click on the row (in other column who is not editable) the edit start and immediately stop.

How to solve?

In addition i would like to have the editing row selected

Thanks

Hi,

I upgrades a Blazor Projekt from net 6, Blazor 3.7 to net 8, Blazor 7.1.
I handled all breaking changes, so it works now.
There is only an issue with the legend style : in 3.7 only the line is shown. But in 7.1 a dot with line.
The code of my chart control was not changed from 3.7 to 7.1.

<TelerikChart Height="200px">
    <ChartPlotArea Background="#FAFAFA"></ChartPlotArea>
    <ChartTooltip Visible="true"></ChartTooltip>
    <ChartSeriesItems>
        <ChartSeries Type="ChartSeriesType.Scatter" Name="@($"{AxleNumber}: {right_text}")" Data="@chartRight" Color="#ff8400"
                     XField="@nameof(ChartDataViewModel.start)"
                     YField="@nameof(ChartDataViewModel.Indicator)" Visible="@right_visible">
            <ChartSeriesMarkers Type="ChartSeriesMarkersType.Circle" Size="4" Background="#ff8400" />
        </ChartSeries>
        <ChartSeries Type="ChartSeriesType.Scatter" Name="@($"{AxleNumber}: {left_text}")" Data="@chartLeft" Color="#0071ff"
                     XField="@nameof(ChartDataViewModel.start)"
                     YField="@nameof(ChartDataViewModel.Indicator)" Visible="@left_visible">
            <ChartSeriesMarkers Type="ChartSeriesMarkersType.Circle" Size="4" Background="#0071ff" />
        </ChartSeries>
    </ChartSeriesItems>
    <ChartYAxes>
        <ChartYAxis Max="YAxis_Max" Min="YAxis_Min" />
    </ChartYAxes>
    <ChartXAxes>
        <ChartXAxis Type="date" BaseUnit="days">
            <ChartXAxisLabels Format="{0:dd.MM.yy}"></ChartXAxisLabels>
        </ChartXAxis>
    </ChartXAxes>
    <ChartLegend Position="ChartLegendPosition.Custom" OffsetX="50" OffsetY="10" Height="10" Visible="@(right_visible && left_visible)" />
</TelerikChart>

How can I get back to old Legend style?

I don't understand what is going on.  I am sure I am missing something obvious.  

I am trying to setup my first Gantt Chart.   It is my understanding that this is setup in 2 pieces. The tree and timeline.   I am able to load the tree.  It comes up and I am able to see hierarchy.

Example of Tree..

I get data in a hierarchy. I assign Parent Ids to each record. I am ok with this. 

What I am struggling with is when I tried to add the GanttViews and it blows. up

Here is my initial load... I have not technically loaded any data. So I see the dates and columns all look good. 

During the loading of the data I get this error..

Clearly I am missing something.  I just don't know what.  

The only thing I have added between it loading the Tree and trying to load the timeline is ...

<GanttViews>

    <GanttWeekView></GanttWeekView>
    <GanttMonthView ></GanttMonthView>

</GanttViews>

Here is how I defined the start of the Gannt Control.

I clearly did not populate something that the Timeline needs. I am not sure what. It looks like all I need is the Start, End and TItle.  But I have tried different variations of that and it still fails. 

I am confused. Any suggestions? 

Probably a bit of a vague question, but is there any way to make the “TabStrip” component tab texts appear vertically or is it planned to support this behavior sometime? I've tried modifying it a bit via css but I'm having problems with containers. I think I'm probably not using the right component for what I want to achieve... but if it helps anyone who is looking for the same idea it is already reflected here.

The default visuals for the DialogFactory are distractingly different (aka ugly) from my application visuals.  Is there any way to modify the predefined dialogs?  I think they're a great idea and they do save me time on creating a custom component, but they seem visually inflexible?
