Bug report

Reproduction of the problem

Possibly related to https://github.com/telerik/blazor/issues/2594

1. Run this example: https://blazorrepl.telerik.com/wAkdbZPo47oCuV5G32
2. Without scrolling the Grid horizontally resize a non-locked column (e.g., In Stock)

Current behavior

(optional)

The first locked column (ID) is rendered after the second locked column (Product Name). When you resize a non-locked column, the ID column disappears and is revealed at its new position after you scroll the Grid horizontally.
The behavior is reproducible with RTL enabled.

Expected/desired behavior

The order of the locked columns should persist.

Environment

• Telerik version: 13.0.0
• Browser: [all]

If LoadGroupsOnDemand="false", I am able to programmatically expand the groups through the state. However, this is not possible when loading group data on demand.

Please allow programmatically expanding the groups when LoadGroupsOnDemand="true". This should go together with an event (OnStateChanged?) that will fire when LOD groups are expanded or collapsed.

Hi,

I would like to have a Expand/Collapse All Grid Groups button in the Grid Header. I know this is possible to do so programmatically outside of the grid but my users want it inside the Grid. 

Thanks,

Humayoon

Description

A column cannot be reordered by dragging beyond the currently visible columns of the Grid. This significantly limits the column reorder functionality only to the visible viewport.

Steps To Reproduce

1. Run this example: https://blazorrepl.telerik.com/QqudFlYZ18zv7Gv547
2. Drag a column header to the right border of the Grid.

Actual Behavior

The Grid does not scroll horizontally while the column is dragged.

Expected Behavior

The Grid scrolls horizontally while dragging the column and allows dropping it beyond the currently visible columns.

2. Click a row in the Grid

Actual Behavior

The following KB article shows a workaround for removing the Grid aggregate labels ("Sum" and "Count") from the exported Excel document: https://www.telerik.com/blazor-ui/documentation/knowledge-base/grid-remove-aggregate-labels-in-excel-footr

It would be nice to have this option as a parameter in the Grid. It would allow to toggle on/off this behavior, instead of having to rely on custom code to work around it. 

Or in the OnBeforeExport method, add extra data to GridBeforeExcelExportEventArgs that contains the aggregates so they can be changed.

 private async Task OnBeforeExcelExport(GridBeforeExcelExportEventArgs args)
 {
     await Task.CompletedTask;

     // Loop through all columns and fix the footer aggregate values
     // Replace the default "Sum: 1234.56" text with just the decimal number
     foreach (var column in args.Columns)
     {
         if (column.HasAggregate)
         {
             // Set the number format for the column so Excel treats it as a number
             column.Aggregate.Field.Value == "MyNewValue";
         }
     }
 }

The Grid's CheckBoxColumn doesn't support the TextAlign property, making it impossible to center the checkbox with just Grid markup, you have to resort to a workaround.

The TextAlign property in other columns causes style="text-align: center" to be added to the underlying table cell.  This would also work for the checkbox column.

See this test:

<table class="table">
    <tr>
        <td class="table-active" style="width: 40px; text-align: center"><input type="checkbox" /> </td>
        <td>test</td>
    </tr>
</table>

Please add the TextAlign property to the CheckboxColumn.

I want to reorder the Grid rows the same way I can reorder the columns - via the keyboard.

For reference: Telerik jQuery Grid drag and drop

Column headers and column data do not match after reordering. 

See this example: https://blazorrepl.telerik.com/GKkFcwlF54CvZoVp34 

1. Reorder Group 1 and Group 2.

2. The column headers within these 2 groups are not reordered with their parent.

Reordering should work according to the rules specified in the documentation: https://www.telerik.com/blazor-ui/documentation/components/grid/columns/multi-column-headers#reordering

Hello,

 there is inconsistency/behaviour/order in events of the Grid: OnStateInit and OnRead. Which leads to scenario with no clear sollution and would be nice to fix it, and how to solve it as "hotfix".
Also i think its not new in 12.x. release, it exists longer ;)

<TelerikGrid TItem="GData" @ref="gHL" OnRead=@GReadItems OnStateInit="@OnStateGHL">
...
<GridAggregates>
@if(1==2){...}
</GridAggregates>
@code{
protected async Task GReadItems(GridReadEventArgs args)
{
	**hack for C)
	if(gHL==null)return;//state init AVOID 2x call gread PRIOR OnStateInit
...// must be called:
args.AggregateResults = rr.ToDataSourceResult(args.Request).AggregateResults;
...
}
void OnStateGHL(GridStateEventArgs<GData> args) //or async Task doesnt matter
{
//default SORTing:args.GridState = new GridState<GData>
	{
		SortDescriptors = new List<Telerik.DataSource.SortDescriptor>
	{
		new Telerik.DataSource.SortDescriptor{ Member = nameof(GData.DatPorizeni), SortDirection = Telerik.DataSource.ListSortDirection.Descending },
		//new Telerik.DataSource.SortDescriptor{ Member = nameof(GData.Skupina), SortDirection = Telerik.DataSource.ListSortDirection.Ascending }

	}
	};
}
}
	

Problematic scenarios, single page, same grid:

A) when NO aggregates markup EXISTS at all
1. OnStateInit
2. OnRead  - gHL IS NULL
=OK

B) when EMPTY aggregates markup EXISTS
1. OnRead
2. OnStateInit
=FAIL
HOW to read and ui data with correct STATE?
https://www.telerik.com/blazor-ui/documentation/components/grid/state

cannot call gHL.rebind, also gHL is null
NONE initinal "sorting,filtering etc" is set, WRONG data,columns,displayed to the user


C) when SOME real aggregates markup EXISTS
1. OnRead
2. OnStateInit
3. OnRead
=partial FAIL("**hack used"), but managed by if(gHL==null)return


D) "hotfix" used with  GridAggregates="@( HasAggregates ? GridAggregatesTemplate : null )"
act as A or C, but gHL is always null, which is also bad againts C)

Expected:
ALWAYS only A) - First 1.OnStateInit THEN 2.OnRead. its the best one, without any additional hacks = UNIFY the event orders and behaviour.
OR
A) or C)
everything else is unmanagable.
 Especially when initial sorting "is must" and aggregates,columns and so on, are managed by user(non static)
B) is completly WRONG: incorrect event order of OnStateInit and OnRead
D) is againts C) (cannot detect reference of gHL)

OR how to solve it generally = what is the way to LOAD gridState, and after that, LOAD Data by defined GridState?

Thanks

Description

When going fast over the Grid rows with the mouse cursor, the rows are highlighted after a delay. The delay is more noticeable on higher resolutions (2560x1440 or higher).

Steps To Reproduce

1. Hover the first Grid row and move the mouse cursor towards the last row (or vice versa).

Actual Behavior

In the app that targets .NET10 the row hover styles are applied with a delay, whereas in the app that targets .NET8 the hover styles are applied as soon as the mouse enters the boundaries of a row.

Expected Behavior

Similar performance in applying hover-related styles.

I am resetting the Grid State by calling Grid.SetState(null). This doesn't reset ColumnState<T>.Locked boolean to false and the columns remain locked.

---

ADMIN EDIT

---

A possible workaround for the time being is to additionally loop through the ColumnStates collection of the State and set the Locked property to false for each column.

Example: https://blazorrepl.telerik.com/QTYmkpvb49c6CPxa42

1. User clicks the sparkled button that opens the AI window in this demo: https://demos.telerik.com/blazor-ui/grid/ai-data-operations

2. User chooses a predefined prompt suggestion, enters one via the keyboard, or uses voice access to dictate one, and clicks apply.  The operation runs successfully and returns output.

3. Now the user clicks the sparkled button again, and the AI window opens. Once open, the prompt text box fills with the previously entered request text.

How to remove or prevent the previously entered request text from filling the text box on every sequential opening of the AI window?

When triggering Grid edit mode through the Grid state and the component is using adaptive mode, the edit form doesn't show.

Possible workarounds include:

• Trigger edit mode through built-in buttons in the Grid command column on in the Grid toolbar.
• Use inline or in-cell editing.
• Use a custom edit form in a separate Window component that fills the entire viewport.
