Hi there,
I have a TelerikGrid with a DateTime column. I use a custom FilterEditorFormat which is localizable depending on the user settings, e.g. "dd/MM/yyy HH:mm:ss". Unfortunately, any '/' in the date component is always replaced by the current culture's DateSeparator. Using any other separator works, e.g. '-'.
Expectation: Use the FilterEditorFormat without modification, unless it's a standard format string like "g" or "D".
I already traced it down to Telerik's FormatHelper class and it seems like a quick fix.
Steps to reproduce:
- Create a TelerikGrid with a DateTime column and a FilterEditorFormat as shown above.
- If required, change the DateSeparator to anything else but '/'.
- Run and open the filter dialog
Please let me know if you need any additional information.
Best regards
Andreas
can you provide a initial File click event handler attribute?
I want the user to be able to click on an initial file to download the file.
Hello,
related to my previous bug report.
When Add / Edit is clicked in the Grid, it causes a Dialog to open.
The dialog has a Form, and if the model for that form is set through OnParametersSet, the method is called in an infinite loop, and the Dialog never gets shown.
(https://docs.telerik.com/devtools/wpf/controls/radgridview/filtering/basic)
(https://docs.telerik.com/devtools/winui/controls/raddatagrid/filtering/datagrid-overview)
The problematic behavior can be reproduced in the following case:
- The DropDownList is at the lower part of the page, so the popup is rendered on top of the main element.
- The popup height is set to "auto".
In this scenario, when the user filters, the popup position remains unchanged but its height is reduced to fit the filter results. Thus, the popup looks detached from the main element. The behavior is not the same when the popup is rendered below the main element as in this case its top part sticks to the main element.
Reproduction: https://blazorrepl.telerik.com/mpEHGzOt25F1Znxi57.

ADMIN EDIT

As a workaround for the time being, you can ensure that the popup has a fixed height, so it does not collapse when there are less items to show. You may keep the default popup height or set your desired one through the settings tag. For example: https://blazorrepl.telerik.com/mpYdcfaN38JvIHgP41.
Creating a new WebApp project template through the extension fails to build. This is caused by incorrect icon type in the MainLayout.razor file.
To make sure the app is correctly built, the Icon type should be FontIcon.
<TelerikButton Icon="@FontIcon.Menu"
FillMode="@ThemeConstants.Button.FillMode.Clear"
OnClick="@( () => DrawerExpanded = !DrawerExpanded )" />
While working on how to connect the filters together, I noticed that the clear button can gets the later part of the CompositeFilterDescriptor stuck in the grid.
Reproducible example: https://blazorrepl.telerik.com/wzuRPRvB00Vlj1Ac28
With the current configuration of the repl, filtering using only the TelerikCheckBoxListFilter and clicking filter will filter the column as expected, and clicking clear will blank out the checklist but won't reset the grid's filtering from those checkboxes until after ticking a checkbox and clicking filter, then unticking all checkboxes and clicking filter again. If the checkbox gets used then the clear button gets clicked, clicking the filter button after using the TelerikFilter without any checkboxes checked will filter based on the checkboxes the grid remembers ANDed with the new values from the TelerikFilter, again until the checkbox gets used and then manually emptied without using the clear button.
If the order of _textFilterValueInternal and _checkFilterValueInternal in the FilterDescriptors list get reversed, then the grid's filter memory issue gets transferred to the TelerikFilter meaning the issue is presumably with the grid itself. Also, if you use one or more values in both filters, then the clear button works as intended if there weren't already filters stuck inside the grid.
The clear button works as expected if filtering with both the filter and the checklist before clearing the filter.
Example images:
Start:
Check some boxes:
Filtered:
Open filter menu and click "Clear":
Re-open the filter menu:
New filter:
Click "Filter":
Re-open filter menu:
Click "Clear" button again:
So the user would have something like: 'Cupcakes (12 count), Mozzarella Cheese - Kraft, ...'
So the autocomplete would filter the string to find the part after the last comma and use that to search, but when the user finds their item and selects it, it needs to append to the string (and add a comma) and not overwrite it. Then continue the cycle.
Attempting to use OnChange does not allow for this to happen. On selection of a dropdown item, it will overwrite the string entirely.
I noticed that when the ReadTimeout property of the FileSelect's FileInfoStream is read, the code seem to block completely.
You will find a Blazor Web App project attached to this ticket showcasing the issue.
Hello,
i am trying to add a Clear Button inside the DropDownList-Component.
I tried to follow the instructions provided here: How do I add a Clear button to a DropDownList? in UI for Blazor | Telerik Forums respectiveley here: Telerik REPL for Blazor - The best place to play, experiment, share & learn using Blazor.
But unfortunateley, the button is never inside the component. It's always next to it or under the component.
In your example provided above, the button is inside the component.
I would love to have any solution for this one. A clear button is needed quite often.
I also have attached our custom component, where we use the Telerik DropDownList Component.
Thank you
Hello,
after uprading fron 7.1.0 to version 8.0.0
on IOS v 16.2, or any version before 17, telerik ui stopped working with this error after navigating between pages:
Microsoft.JSInterop.JSException: Could not find 'TelerikBlazor.initMediaQuery' ('TelerikBlazor' was undefined).
even, when mediaquery is not present at the 2 pages between navigating occurs.(login->landing page)
what iam tried on NEW clean device(so no caching troubles):
- changing order of scripts in app.razor
- adding defer
- addin autostart=false + DOM event
https://www.telerik.com/blazor-ui/documentation/getting-started/what-you-need#javascript-file
- any kind of browsers(on ios everything is webkit-safari)
- independent test on external emulator ip12 ios 16.2
https://appetize.io/app/standalone_lahzvlutkzrno7sqs36cqlj5wy?device=iphone12&osVersion=16.2
attached examples are for comparing of descriped attemps to get it work - both failed. But on v7.1.0, works ok - both.
Is there any breaking changes, which must be modified to get it working?
Thanks
Telerik UI for Blazor requires unsafe-inline styles in order to render style attributes from the .NET runtime.
Please add support for strict CSS CSP without the need for unsafe inline styles.
===
TELERIK EDIT:
Due to the complexity and required effort to add strict CSS CSP support:
- The feature request must gather enough votes.
- We may implement it gradually. That's why, everyone who is interested, please specify the exact components and features that you need to be compliant sooner.
Dear all,
Please, Can you send the source code for this template with Arabic language https://demos.telerik.com/blazor-coffee/
Please add Arabic translate from right to left automatic when select Arabic language
Add support for DateOnly and TimeOnly properties to the ToODataString() method in the DataSourceExtensions namespace.
===
TELERIK NOTE
@Steven I forked this thread from the already complete feature request Provide support for DateOnly and TimeOnly structs for the respective pickers
Currently DateOnly and TimeOnly types are not supported by the ToODataString() method. As a result, they are serialized with the default ToString() method. Please use DateTime instead or implement a custom serialization method. Downloading our source code and using the built-in method as a base is also an option.
===
ORIGINAL POST
Would you have any updates regarding this support for early 2024?My main issue regarding this at the moment is:
- My Backend returns DTOs with DateOnly properties.
- I wish to use these properties in a grid
- So far... So good... We can see the items etc... But then...
- We want to filter these properties...
- When we get the OData query... Our DateOnly is not in the correct ISO format... As there's no support for those in DataSourceExtensions.cs
I already tried solving this by creating my own GridColumn type, but I'm afraid there's nothing I can do about the OData serialization without just writing our own DataSourceExtensions... At which point we're just making it confusing for other developers needing to include this...
public class DateOnlyGridColumn : GridColumn
{
private DateOnly? _filterValue;
public DateOnly? FilterValue
{
get => _filterValue;
set
{
if (_filterValue != value)
{
_filterValue = value;
StateHasChanged();
}
}
}
public DateOnlyGridColumn()
{
DisplayFormat = "{0:dd/M/yyyy}";
FilterMenuTemplate = FilterMenu;
FilterMenuButtonsTemplate = FilterButtons;
}
private RenderFragment<FilterMenuTemplateContext> FilterMenu => (context) => (builder) =>
{
builder.OpenComponent<TelerikDatePicker<DateOnly?>>(0);
builder.AddAttribute(0, "Value", FilterValue);
builder.AddAttribute(2, "ValueChanged", EventCallback.Factory.Create<DateOnly?>(this, (value) => FilterValue = value));
builder.CloseComponent();
};
private RenderFragment<FilterMenuTemplateContext> FilterButtons => (context) => (builder) =>
{
// Filter button
builder.OpenComponent<TelerikButton>(0);
builder.AddAttribute(1, "OnClick", EventCallback.Factory.Create<MouseEventArgs>(this, async () => await ApplyFilter(context)));
builder.AddAttribute(2, "ThemeColor", ThemeConstants.Button.ThemeColor.Primary);
builder.AddAttribute(3, "ChildContent", (RenderFragment)(childBuilder =>
childBuilder.AddContent(0, "Filter")));
builder.CloseComponent();
// Clear button
builder.OpenComponent<TelerikButton>(4);
builder.AddAttribute(5, "OnClick", EventCallback.Factory.Create<MouseEventArgs>(this, async () =>
{
FilterValue = null;
await context.ClearFilterAsync();
}));
builder.AddAttribute(6, "ChildContent", (RenderFragment)(childBuilder =>
childBuilder.AddContent(0, "Clear")));
builder.CloseComponent();
};
private async Task ApplyFilter(FilterMenuTemplateContext filterContext)
{
if (filterContext == null || string.IsNullOrEmpty(Field) || !FilterValue.HasValue)
return;
var filter = new FilterDescriptor
{
Member = Field,
MemberType = typeof(DateOnly),
Operator = FilterOperator.IsEqualTo,
Value = FilterValue.Value, //.ToString("o") Convert to ISO-8601 format
};
filterContext.FilterDescriptor.FilterDescriptors.Clear();
filterContext.FilterDescriptor.FilterDescriptors.Add(filter);
await filterContext.FilterAsync();
}
}
We need a formal, Accordion component. This is missing like a sore thumb !
The Accordion should be the first component in the component list.
Using the panel bar is not the same as the functionality of Accordion. So, do not mark this request as a duplicate of a panel bar enhancement request.
This is a simple component and I request you to prioritize and release it urgently in the next release.
Thanks.
This seems to be a regression in this version. I cannot find an open issue on it. I think it's the same as this issue.
Here is a REPL link with the issue recreated. The bug happens the second time you open the dialog. You can see on the first close of the dialog that the parent window z-index is increased by 2. Then the second time you open the dialog the z-index is less than it's "parent" component.
Please link me to the current issue if there is an open duplicate.
Kind regards,
Linda
It appears there are some issues with encoding special characters in the DataSourceExtensions.ToODataString extension method.
See snippet below.
var ds = new DataSourceRequest()
{
Filters = [new FilterDescriptor("FieldName", FilterOperator.IsEqualTo, "Route #")],
Sorts = []
};
{
Console.WriteLine(ds.ToODataString());
$count=true&$filter=(FieldName%20eq%20%27Route%20#%27)&$skip=0
This results in a malformed url as the last part of of the query is interpreted as a fragment due to this character not being encoded.
After reading your documentation, it appears that the Pager Position enum only allows for the grid pager to be at the top OR the bottom of the grid.
It would be most excellent to allow it to be BOTH. For very large grids, it would be convenient for the user to see the grid at the very top, but if they do happen to need to scroll to the very bottom of the grid, seeing the pager component there would also be convenient for the user.
This is in regard to this page:
https://www.telerik.com/blazor-ui/documentation/components/grid/paging
Please add a .Both option to the PagerPosition enum that allows both Top and Bottom at the same time.
Thanks! :)
I've been looking at your Keyboard Navigation page:
https://demos.telerik.com/blazor-ui/grid/keyboard-navigation
If you are navigating in the Grid and arrow over to the "+" sign and press ENTER it expands the Details. Then you can press TAB to access the button within the details. Great. Your demo works fine.
However, on my grid, I have another grid in my Details section. I would like to be able to expand the Details section and then TAB into those details so I can access the link in the header of the grid, and also be able to use arrow keys to navigate around this sub grid. Well, honestly MOSTLY I just wanted to be able to tab to the "View Checkout History" link within the Details grid. See attached screenshot.
However, pressing TAB after expanding the details simply moves the focus to the first button in the next column of that row. It doesn't go into the Details section like your web demo does for a button.
Please expand your Keyboard Navigation capabilities to allow more navigation into the Details section other than just a button like your demo shows. I'll bet a lot of people probably have sub-grids within their details section.
Thanks!
