OnChange and OnChange event for editors (TelerikTextBox, NumericTextBox, and others) is not fired in InCell edit mode with Tab key.

OnBlur event for editors is not fired in InCell edit mode with Enter key.

It looks like the built-in validation does not respect clearing the edit item through state.  If you remove invalid edit item through Grid State, the Grid stays in edit mode and the OnRowClick stops firing.

I know that I can bind the PageSize property to a variable, but then I have to build a dropdown with the available page sizes in a separate control. Are there plans to integrate a page size selection into the existing paging controls? Perhaps a PageSizes property that takes an array of integers.

Example:

PageSizes = "[10, 25, 50, 100]"

These would then be converted into a dropdown integrated into the existing paging controls on the grid.

With OnRead, AllPages cannot be exported because the grid Data only has the current page: https://docs.telerik.com/blazor-ui/components/grid/export/excel#notes:

If you are using the OnRead event, only the current page of data will be exported, because that's all the grid has at the time of the export action.

 

I load my data via "OnRead", because i need to implement pagination by myself, and I would like the export option to work with that too.

Hello,

Do you have any sample for custom group Header template.

 

e..g. To  calculate the value of the column based on the other fields.

Hello,

First of all: thank you for implementing the Excel like filtering with the new CheckBox Filter! This was a feature that was highly sought after in our development team.

But there is one thing I am missing: the checkbox list has no option for sorting.

If we want to sort our filters now we have to implement the FilterMenuTemplate in every column that has filtering active (which are a lot) and define the list with filter options and filter it ourselves. 

Is this something that can be fixed easily?

---

ADMIN EDIT

We will probably sort ascending the values by default (out-of-the0box), and any other custom sorts should be implemented through the filter menu template.

The TelerikGrid is kind of missing a "None" Value in the enum for the EditMode.

We need to disable the edit mode based on a value from the model (role access restricted), and I don't see any way this is possible without copy-pasting the entire grid under an if statement.

 

------ADMIN EDIT-------

A possible workaround at the moment is to set the "Editable" parameter of the columns to "false" or not use a command column with "edit".

Another workaround can be to attach a OnEdit handler and cancel the event based on the view model flag only. If the user cannot edit - always cancel.

Can you add a confirmation popup to the grid row delete like what is in the JQuery UI library?

---

ADMIN EDIT

As of 2.23.0 predefined confirmation dialog is available for use with just a few lines of code and you can achieve that behavior through the OnClick event of the command button:

<TelerikGrid Data=@GridData EditMode="@GridEditMode.Inline"
             Height="500px" AutoGenerateColumns="true" Pageable="true"
             OnDelete="@DeleteItem">
    <GridColumns>
        <GridAutoGeneratedColumns />

        <GridCommandColumn Width="100px">
            <GridCommandButton Command="Delete" Icon="delete" OnClick="@ConfirmDelete">Delete</GridCommandButton>
        </GridCommandColumn>

    </GridColumns>
</TelerikGrid>

@code {
    //for the confirmation - see the OnClick handler on the Delete button
    [CascadingParameter]
    public DialogFactory Dialogs { get; set; }

    async Task ConfirmDelete(GridCommandEventArgs e)
    {
        Product productToDelete = e.Item as Product;
        string confirmText = $"Are you sure you want to delete {productToDelete.Name}?";
        string confirmTitle = "Confirm Deletion!";
        //the actual confirmation itself
        bool userConfirmedDeletion = await Dialogs.ConfirmAsync(confirmText, confirmTitle);
        e.IsCancelled = !userConfirmedDeletion;//cancel the event if the user did not confirm
    }

    // only sample data operations follow

    public List<Product> GridData { get; set; }

    protected override async Task OnInitializedAsync()
    {
        GridData = Enumerable.Range(1, 50).Select(x => new Product { Id = x, Name = $"Name {x}" }).ToList();
    }

    private void DeleteItem(GridCommandEventArgs args)
    {
        Console.WriteLine("DELETING ITEM");
        var argsItem = args.Item as Product;

        GridData.Remove(argsItem);
    }

    public class Product
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
}

Then setting the TextAlign property of a GridColumn element to ColumnTextAlign.Right, the grid cells are right-aligned, however the header and total row do not respect the setting and remain left-aligned.

Here is the scenario and how to reproduce the issue:

  1. A Grid with a horizontal scrollbar. All columns have explicit widths, according to requirements.
  2. The first 3 columns are locked (frozen).
  3. Make the frozen columns 1 - 3 smaller. Save the Grid state.
  4. Refresh the page and restore the Grid state in OnStateInit.
  5. Scroll the non-frozen columns to see how the frozen columns are positioned, according to their previous larger widths. Now there are gaps between these columns.
  6. The reverse issue occurs if the frozen columns are expanded in (3). Then, after state restore they overlap.

Release 2.26.0
If I open the filter menu, choose filters, but do NOT click Filter, these filters go into the grid state, and they are applied with the next data operation (such as paging or sorting, or filtering some other column). Clicking away like that should clear the filters in the popup instead of put them in the state, or it should apply them immediately so that the filter icon also gets marked as active filter.

Hi,


I am getting an unhandled exception when setting the GridState of a TelerikGrid with the SetState method that has multi-column headers.


Exception:

Unhandled exception rendering component: More than one sibling of element 'col' has the same key value, 'Telerik.Blazor.Components.GridColumn'. Key values must be unique.

Example grid:

<TelerikGrid @ref=@TestGrid Data=@TestData FilterMode=GridFilterMode.FilterMenu Sortable="true" SortMode=SortMode.Multiple TItem="TestDataItem">
   <GridColumns>
       <GridColumn Title="Test Column 1" Field=@nameof(TestDataItem.TestColumn1) />
       <GridColumn Title="Test Column Group" />
          <Columns>
             <GridColumn Title="Test Column 2" Field=@nameof(TestDataItem.TestColumn2) />
             <GridColumn Title="Test Column 3" Field=@nameof(TestDataItem.TestColumn3) />
          </Columns>
       </GridColumn>
   </GridColumns>
<TelerikGrid>

 

I have tried to set the Id or @key of the columns but nothing has fixed this issue. 


Any help you can provide regarding this is appreciated.

Regards

Enable the user to select multiple records, using the shift key, across different pages (scroll downs) when the Grid has virtual scrolling.

Currently, in Incell EditMode the Telerik Grid is triggering the crud events per row. Firing the events on every cell will give the control to the customers to decide whether to update the model for every field, or conditionally based on their business logic and app setup. In addition, the Field and Value properties of the GridCommandEventArgs should be applied to ensure that the user is aware of what exactly has changed.

When adding a new item to a grid, if you type in information into the required fields, before hitting save, it also allows you to edit a record. at this point, you have a new record and an edit record both in edit mode.

If you reorder a column and then lock it, visually it looks locked and the functionality for a locked column is correctly supported.

However, the Locked property of the ColumnStates in Grid State for that column remains "false". Locked = "true" is applied based on the initial column position.

Try to dynamically switch between Scrollable and Virtual modes. You would need to manually refresh the Skip property through the Grid state, or it won't work.

 

-----------ADMIN EDIT------------

You can use the ValueChanged handler to manually refresh the Skip property as shown below.

public TelerikGrid<ExpandoObject> TelerikGrid { get; set; }

private bool IsPageable = false;

private int Page { get; set; }

public void ChangeHandler(bool value)
{
    //Sync the paging with scrolling

    if (value)
    {
        IsPageable = value;
        var state = TelerikGrid.GetState();
        state.Skip = 0;
        state.Page = 3;

        _ = TelerikGrid.SetState(state);
    }

    IsPageable = value;

    StateHasChanged();
}
