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 

The Grid component creates an invalid property value in its style for the <table> tag like shown below (some of the contents omitted for brevity). Notice the "width: ;" which should have a value in it.

<table style="height: auto; width: ;"></table>

This can be observed for example by creating a page with the below code and the using the browsers developer tools to examine the elements. Both Grids will have their CSS width property be invalid.

<TelerikGrid Data="@data" AutoGenerateColumns="true">
</TelerikGrid>

<TelerikGrid Width="200px" Data="@data" AutoGenerateColumns="true">
</TelerikGrid>

@code {
    private List<Product> data = new () { 
        new Product() {
            Id = 2,
            Name = "Hello product"
        }    
    };

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

Hello

The new adaptive toolbar I think doesn't follow the same style as other components, particularly scrollable tabs.

https://demos.telerik.com/blazor-ui/grid/adaptive

The UI scroll buttons shouldn't just disable, they just be hidden/removed from the UI altogether when they are not active (as it is pretty confusing to the user otherwise) - they should only appear when they need to appear. They also take up real-estate for no value.

Telerik already have the same concept in the UI for the scrollable-tabs seen here;

https://demos.telerik.com/blazor-ui/tabstrip/scrollable-tabs

So I see some inconsistency between the 2 UI's and think they should not appear as does on scrollable tabs.

When enabling resizing and reordering for the Telerik Grid, using `MinResizableWidth` to set minimal column width will apply the constraint to the column position rather than the actual movable column. This means applying a min width of 200px to the first column will work as expected until the column is moved to another position. Now the column in question no longer has the min width applied, and the column that has moved into the first position has the 200px min width constraint. 

It appears this is due to the constraint being applied to the `data-col-index` rather than the `data-col-initialization-index`, or something to that effect.

The following example has a 200px min-width constraint applied to the "Name" first column, and no custom min-with applied to "Address" second column. Switching the columns by moving the "Name" after the "Address" will apply the constraint to the "Address" and not the "Name".

Currently using 7.1.0 but looks to be an issue in later versions as shown by the REPL example. Tested in Firefox and Chrome.

The column position is arbitrary and the bug isn't due to the constraint being applied to the 0 column, applying the constrain to all even columns then shuffling would result in the constrain still being applied to all even columns.

Description

Regression introduced in version 10.0.0.

Steps To Reproduce

1. Run this example: https://blazorrepl.telerik.com/GJkCGCvE51aGglud38
2. Filter a Grid column and observe the log below the component.

Actual Behavior

The OnStateChanged event fires 4 times

Expected Behavior

The OnStateChanged event fires 2 times (see https://www.telerik.com/blazor-ui/documentation/components/grid/state#onstatechanged).

Browser

All

Last working version of Telerik UI for Blazor (if regression)

9.1.0

When Virtual Scrolling is enabled and the grid is set to inline editing, clicking the Add button does not start editing on the first click. The button must be clicked twice for a new row to enter edit mode.

Steps to Reproduce:

1. Open this example - https://blazorrepl.telerik.com/QfaZEibY50abpby200

2. Scroll down the grid.

3. Click the "Add" button.

Upon the first click, a new row is inserted but then immediately closed. You have to click it a second time to insert a new row.
