I have a paged TelerikGrid loaded using OnRead event with 2 filter modes: Inline and programmately.

With inline filter i manage a FilterCellTemplate and call FilterCellTemplateContext.FilterAsync() to refresh the grid after setting the filter value.

If i set a filter programmately, to update the grid i call Grid.Rebind(), but i need to set the grid to page 1, so i need to set the Page property binding to 1 before calling Grid.Rebind.

There is a better way to refresh the grid for filtering programmately? the best would be a method to call (as done with FilterCellTemplateContext.FilterAsync()) who manage the page reset.

Thanks

Hello!

I want to export Blazor grid content to CSV and make some changes before export. This example works fine with GridCommandButton 

Blazor Grid Export Export Events - Telerik UI for Blazor

I want to use a standard button instead of GridCommandButton. 

     <Button ..
             OnClick="ExportGridData">
         Export
     </Button>

    internal void ExportGridData()
    {
        gridRef?.ExportToCsv();
    }

My issue is, executing ExportToCsv does not trigger OnBeforeExport. Is there a way to trigger OnBeforeExport when calling ExportToCsv() from a button click event?

Thank you.

Hello,

We recently upgraded to Telerik v7.0 for our controls and since then expanding a single item always expands all items.  Has anyone else run into this or does anyone know a workaround?

Does anyone know if there is a way I can export Blazor Gannt to excel?  

At this rate I would take anything I can get? (Data and/or timeline) 

Hi!

I'm using the FileSelect component. When accessing the data, it's of type FileSelectFileInfo, which has a stream of type FileInfoStream, which is disposable.

So, do I have to dispose it after having read the data?

Lots of Greetings!

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?

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

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; }
   }
}
