Grid with columns price1 and price2. Enter value in price1, switch to price2, enter value there, and editor is set to old value after async events finish.

The value entered in price2 is correctly set to the property, but the editor reverts to the previous value. If you escape edit mode of the cell, the value entered before the events finish will be shown.

On (fast) tabbing and entering values, this removes the first values entered before the async background events finish.

I tried reproducing the problem in REPL, but could not get the exact same behaviour. In our case no specific value is being set to price2, it just reverts.

How would you approach preventing the editor from being overridden by other cells' delayed events?

Using CheckBoxList filtering changes the filter menu for all columns. I would like to specify CheckBoxList only for certain columns, but that doesn't currently appear to be an easy option.

1) Leave as FilterMenuType "Menu" but implement a custom filter template for the columns I want. That would be the most obvious, but CheckBoxList is not a usable control on its own?

2) Or do the inverse, use FilterMenuType "CheckBoxList" and implement a custom filter template for all the columns where I don't want to use that. Seems like a lot of extra work to manually recreate default filters.

3) I guess I roll my own clone of the CheckBoxList control and use that like #1 on individual columns?

Any chance the CheckBoxList control could be publicly exposed for direct use?

I added a comment to this feedback post.  In this post, I made a comment on how to get Tab select working in a grid component for a combobox.

It would be nice if tab select was a parameter for any dropdown component and autocomplete. Maybe a parameter called "TabSelect"? It would need to fire before the grid component picks up the Tab key first in InCellEdit mode. 

If that was changed above, then the grid component could have the following:

Enter key to move down the list, and Shift-Enter keys to move up the list. Is there a way to do that currently, or could it be added?

Grid popup editing throws about parameterless constructor even when I use the OnModelInit event.

The inline and incell edit modes are still working.

The regression occurs in version 4.2.0.

Hello,

after updating to the versin 4.6.0 from 4.5.0, almost all svg icons dissapeared(inside the grid). No erros, no console warnings.

Is there some breaking changes or aditional steps how to bring them back?

Original markup without changes(first blue button in example should have "play" icon at the beginning):

<TelerikButton OnClick="@(_ => OZRowCmd(null,20))" Icon="@FontIcon.Play" Title="Zahájit novou" Class="bg-primary" Size="@Telerik.Blazor.ThemeConstants.Button.Size.Large">Zahájit novou</TelerikButton>

Hello,

 when using grid with multiple-selection mode and row template, ONLY single row selection works. Not able to select multiple rows. Grid somehow internally "reverts"(lose) selection to single row.

Here is full detail, with video and sample "what acts weird". Start with the post " Michal - Posted on: 19 Oct 2023 08:38":

Greetings,

When using single selection mode, a row can be selected either by clicking the checkbox or by clicking on the rest of the row. There is no difference at all. Now, let's say I have a grid with multiple selection mode enabled, e.g.:

<TelerikGrid Data="listOfFoos" SelectionMode="GridSelectionMode.Multiple">
    <GridColumns>
        <GridCheckboxColumn SelectAll="true" SelectAllMode="GridSelectAllMode.All"  />
        <GridColumn Field="@nameof(Foo.Name)" Title="Name" />
    </GridColumns>
</TelerikGrid>

public class Foo {
    public string Name { get; set; }
}
public List<Foo> listOfFoos = [ new Foo{Name="First"}, new Foo{Name="Second"}, new Foo{Name="Third"} ];
   

When we click an unselected row, the behavior varies depending on where we click exactly:

• if we click on the checkbox of the unselected row, the unselected row becomes selected. Previously selected rows are still selected. Everything is fine.
• if we click on the unselected row but not on the checkbox (e.g. on another column), the unselected row becomes selected but previously selected rows are unselected.

This notably makes multiple selection impossible if we click on the row but not on the checkbox and gives the impression we are using single selection mode. It is especially strange if we consider the existence of the CheckBoxOnlySelection parameter of <GridCheckboxColumn> whose name suggests we can select using the rest of the row by default.

Hi,

 it seems that grid.GetState() and FilterDescriptors, contains +1 "dummy" object.

- If it is by design, ok, BUT then, how to bind this filter descriptor to the ie TelerikFilter? = It displays that dummy object as it is, and confusing end users. Or how to "identify 100%" that is some kind of dummy value to be trashed?

How to reproduce:

1 run the repl demo

2 put "a" into the first colum(Name) filter

3 click button and observe the content of filter descriptors(serialized below the grid - RED is wrong, Green is expected as ok)

similar, but not the same(iam came from here):

Thanks for the tip, clarification, or removing that redundant values.

Hi,

I have spent a while looking for the feature to move the Footer Template to the first line of the Telerik grid. Is this currently possible with a parameter I'm unaware of? How possible would this be to do if not. 

Kind Regards,

Elliot

There seems to be no System.Type that will allow a GridColumn to be specified with the 'FieldType' attribute to receive a TelerikTimePicker

typeof(DateTime) --> TelerikDateTimePicker

typeof(?) --> TelerikTimePicker

<TelerikGrid Data="@gridDataExpando" Width="100%" Sortable="false" Pageable="false" Resizable="true" ShowColumnMenu="false"
             ScrollMode="@GridScrollMode.Scrollable"
             Height="100%"
             EditMode="@GridEditMode.Incell"
             OnUpdate="@UpdateHandlerExpando"
             OnEdit="@EditHandler">
   <GridColumns>
      @{
         var firstItem = gridDataExpando.FirstOrDefault();
         if (firstItem != null)
         {
            var dictionaryItem = firstItem as IDictionary<string, object>;
            foreach (var item in dictionaryItem)
            {
               if (!item.Key.Contains("Id"))
               {
                  <GridColumn Field="@(item.Key)" FieldType="@(this.GetDataType(item.Key))" Width="140px" DisplayFormat="{0:hh:mm:ss tt}">
                     <HeaderTemplate>
                        <span>@item.Key</span>
                    </HeaderTemplate>
                   </GridColumn>
               }
            }
         }
      }
   </GridColumns>
</TelerikGrid>

Cuando agrego GridAggregates el exportador de excel no me permite dejar limpia la fila de Totales (FooterTemplates) para unicamente dejar el Dato me coloca la siguiente estructura: "aggregate_sum: X" y al remover el aggregate_sum de los archivos de recursos me deja el texto ": X" por lo que la cadena sigue sin quedar limpia.

De igual manera en mi grid view tengo la columna de Totales y no la agrega al archivo que se exporta los totales como se ve en la imagen:

I've customized the GridColumnMenu to only show the Column Chooser and assign Locked Columns (disabled all others, including Sortable):

<GridColumnMenuSettings
	FilterMode="@ColumnMenuFilterMode.None"
	Lockable="true"
	ShowColumnChooser="true"
	Groupable="false"
	Sortable="false"
	Reorderable="false">
</GridColumnMenuSettings>

I'm handling the sorting by clicking directly on the column header.   In that configuration, the menu icon is highlighted for the actively sorted column:

This is misleading because the user cannot affect the sorting via the column menu.  If Sortable = "false", I'd expect no indicator difference in the column headers.

Consider the following scenario:

1. A user focuses a specific Grid cell through keyboard navigation.
2. The user tabs out of the Grid and then tabs back in.

In this case, the Grid should focus the last focused cell in step 1. Instead the Grid focuses the first header cell.

1. Go to https://demos.telerik.com/blazor-ui/grid/keyboard-navigation 
2. Click a data cell.
3. Click `Tab` or `Shift + Tab` to exit the Grid data area.
4. Click `Shift + Tab` or `Tab` to go back to the Grid data area.
5. Compare with https://www.telerik.com/kendo-angular-ui/components/grid/keyboard-navigation
