The Grid PageSizes DropDownList will not select a new value if it the current value is not visible in the open dropdown. This can happen if there are too many items in the DropDownList and the user has scrolled the PageSizes dropdown.
The problem occurs only when Navigable="true".
Here is a REPL test page
The easiest workaround is to fewer items in the PageSizes DropDownList, so that there is no need for scrolling.
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>
Currently, if I call Grid.AutoFitAllColumnsAsync "too early" it throws a null reference exception.
I am aware that this is a limitation but the behavior can be improved. For example, handle the exception and provide some useful information or give me a programmatic way to know if it's too early to call autofit.
I have a Grid with TItem="Dictionary<string, object>". I am not able to programmatically set EditItem and EditField through state.
I tried saving the state while editing to ensure the EditItem and EditField will be properly stored. When I try to retrieve this state object afterwards nothing happens.
Reproduction: https://blazorrepl.telerik.com/GnvYaIbd19iOZ6GH08.
On Hierarchy grids with Inline edit mode, I noticed that if a row is currently being edited and I try to expand the row to show the child grid an exception is thrown: "Error: System.InvalidOperationException: TelerikValidationComponent requires a cascading parameter of type EditContext. You can use Telerik.Blazor.Components.TelerikValidationTooltip`1[System.String] inside a EditForm or TelerikForm".
The problem stems from a validation tool inside the Grid EditorTemplate.
When you click on a cell which has an Editor Template with a NumericTextBox the text inside does not always get selected/highlighted. This is observed only in Server type applications.
Reproduction
1. Copy the code from this REPL into a Server side project or directly download the attached Sample Project.
3. Tab in and out of the Count column.
4. The NumericTextBox does not always select the number inside.
5. [Video Example](https://screenpal.com/watch/c0QtXtV5iMR)
Current
The NumericTextBox does not always select/highlight the number inside
Expected
The NumericTextBox always select/highlight the number inside
Hi
The reset button is not working when we use the column template with the Telerik grid. How to solve this problem? Can you please send it example for reference?

**Description**:
I've encountered an issue with the Telerik Grid component in Blazor where caching the grid state, specifically the filtering state, leads to a casting exception upon reloading the page.
**Steps to Reproduce**:
1. Set up a Telerik Grid with a nullable enum column (e.g., `LeadStatuses? Status`).
2. Apply a filter to the `Status` column.
3. Save the grid state (including the filter state) to cache.
4. Refresh the browser.
5. Load the grid state from cache and apply it to the grid.
**Expected Behavior**:
The grid should load with the previously applied filter without any issues.
**Actual Behavior**:
A casting exception occurs, specifically: "Specified cast is not valid."
**Additional Information**:
- The issue seems to be related to filtering and saving state to the grid. When the column is removed, the error doesn't occur.
- Clearing the filter from the cached state for gid will work.
- The exact error message is:
```
Unhandled exception rendering component: Specified cast is not valid.
Hello,
in some cases there is no way to scroll grid using mousewheel. Try this REPL please - https://blazorrepl.telerik.com/GdkXuLuX10P8sOF040. Scroll down, focus any cell in the last row and try to scroll up using your mouse wheel again. Grid always scrolls back to the last row.
Can you check that please?
Very thanks.

Using the following configuration does not produce the expected result:
<GridSettings>
<GridPopupEditFormSettings ButtonsLayout="FormButtonsLayout.Center"/>
</GridSettings>
The button layout is always left no matter what you choose.

ADMIN EDIT

Possible workarounds for the time being are to position the buttons with CSS or use a Popup Buttons Template.
When you zoom out, the span that displays the Grid pager's content has its style set to display: none, and it does not always reappear when you zoom in after that.
Reproduction
1. Run this REPL2. Enlarge the Preview Side of the REPL as much as possible
3. Zoom out so the pager is hidden
4. Zoom in again
5. Pager does not reappear

Hello,
The issue can be reproduced in a Grid with column virtualization enabled and Navigable set to true. Please run this REPL snippet https://blazorrepl.telerik.com/QHusmyOJ027Rp5Ok38, click on any column, the appropriate row will be selected and the corresponding table cell will be focused. Try to navigate to the right by using Right cursor key - you will not be able to navigate through the whole table, values in last columns will not be displayed and the grid seems think they are in the same cell with User Number in my particular case. When you use Left cursor key and then the Right one again you will not be able to see even these columns headers.
I attached a small video to better demonstarte the issue on my particular machine.
Very thanks.
Miroslav
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.
is there a way to make the Filtering in a grid work with wildcard symbols like '%' or '*' ?
I have checked the page https://docs.telerik.com/blazor-ui/common-features/filter-operators
For strings none of the possible operators seems to support wildcard symbols, they all treat it the symbol "as is" leading to no results.
Guessing that the filtering is using Linq and Expressions so it would be nice if the FilterDescriptor constructor could accept a predicate function as parameter how the FilterValue is to be evaluated. I can see in the API reference that there is a protected method:
CreateFilterExpression(ParameterExpression parameterExpression)
but that is not usable / accessible when programmatically working with FilterDescriptor instances.
Do you have plans for allowing wildcards in filter or offering new FilterOperators like "Regex" ? Or plans where a client could implement their own custom FilterOperators?
Thanks
Frank
