Currently using Telerik.DataSource.QueryableExtensions.CreateDataSourceResult() results in queryable.Count() + queryable.Skip(...).Take(...). done seperatelly. EF Core specific tests are already present it seems, based on decompiled code, I can see: "if (!sort.Any() && queryable.Provider.IsEntityFrameworkProvider())".
Request: Add support for other ORM's that are more capable than EF Core. In case of pagination, window-function could be used to save from extra count query. A short sample bellow:
var dbResults = await queryable
.Select(x => new {
Item = x,
TotalCount = Sql.Ext.Count().Over().ToValue()
})
.Skip(() => offset)
.Take(() => limit)
.ToListAsync();
var count = dbResults.FirstOrDefault()?.TotalCount ?? 0;
var items = dbResults.Select(x => x.Item);Read more about Window functions: https://statics.teams.cdn.office.net/evergreen-assets/safelinks/1/atp-safelinks.html
Hello,
We use extensively the features of Telerik WPF RadMap and are now migrating to Blazor. So we are trying to use TelerikMap to cover our needs.
TelerikMap doesn't support WMS (most important) and vector tile (nice to have) layers.
Implementing them directly is not really important but having some class available for us to override to implement our way could be enough.
In Telerik WPF RadMap, we had TiledProvider and TiledMapSource from which we made our own implementations to cover our needs (WMS with specific parameters mostly), we override the method GetTile and from here we can do whatever we want.
It would be nice to have the same system in Blazor
Thanks
Thomas
See below repl

The first dropdown is populated correctly, it is not in a FormItem or Template
The second one, populated in the same way but inside a FormItem context does not show the data, it only redraws and shows data when entering another control i.e. the other working dropdown.
This was previously working when the application was using .net 6 and Telerik 3.6.1
It has since been updated to .net 8 and Telerik 5.1.1
What is the correct way to populate this?
Can you provide more information?
Thanks.
Hi,
We use compact sized grid all the time in our application.
However, with sorting and filtering enabled, the icons take too much space in the header cell and make the actual header text hard to read.
Please consider scale down those icons and reduce padding.
Thanks and best regards,
Peili
Demo: https://blazorrepl.telerik.com/mSOIQZvO51cwrorJ49
===ADMIN EDIT===
To reduce the size of the icons and the font in a Compact Grid, you can follow the approach from the knowledge base article How to make Compact Grid elements smaller.
On Blazor Filter, please consider option to drag and drop rules to re-order the rules. It's a common user request that when creating complex rules that user has ability to move rules around without having to delete and create again. User loses information and data when rules are deleted and can be difficult to relocate in long drop downs.
Ability to drag and drop move of existing rules would improve user experience. Any change to GUI should also reflect in updated FilterDescriptor.
===
ADMIN EDIT
===
The order of the filter rules in one group does not make a difference for the FilterDescriptor. Thus, the current request applies to dragging filter rules from one group to another.
On Blazor filter field parameters, please consider adding
1/ Group options, eg using demo sample fields drop down looks like this
Id
Quantity
Freight
Country
Ship to
Ship Address
but it would be useful to allow groping fields by common categories?
Group-1
-Id
-Quantity
-Freight
Group-2
-Country
-Ship to
-Ship Address
2/ Related, can you also add sort index for group and fields so they can be sorted by index rather than field name. Sometimes groups and fields require different order that is not always alphanumerical and may change order based on other selections.
3/ Maybe consider feature parity with filter field options here querybuilder
Horizontal scrolling in the grid works when its width is set to a fixed value (px, rem, etc.). But the h scroll disappear when a percentage is assigned to the width of the grid.
This seems to be a known 'feature' to Telerik:
A sensible behaviour is to have the horizontal scrolling enabled and at the same time being able to set the grid to percentage width.
Hi,
I have a little problem with changing the LoadGroupsOnDemand value. Depending on the data in my grid, I set this value to true or false. When updating grid data requires changing the LoadGroupsOnDemand value, I can't do it this way:
LoadGroupsOnDemand = true;
GridData = result;
GridRef.SetStateAsync(GridRef.GetState());This code throws me an exception.
I need to do something like this to make it work:
LoadGroupsOnDemand = true;
GridRef.LoadGroupsOnDemand = LoadGroupsOnDemand;
GridData = result;
GridRef.SetStateAsync(GridRef.GetState());This is the code that is executed in onclick. After OnRead is executed, the exception is thrown.
Let me know if you need more information.
Hi,
I haven't been able to find this as a request or as a topic of discussion (If it iss feel free to point me to it and close this request) but I feel the Grouping feature is limiting. If I use the group field in say the DropDownList the grouping works fine but it orders it alphabetically.
I propose adding a number of features to enhance this. The first being a GroupAscending or GroupDescending tag. Takes a boolean value and allows you to change the order to ascending (default/True) or descending (False).
The second, and more complicated feature upgrade could be a GroupOrder tag. This would take a List of the group field names ordered in the way you require and apply that order to the grouping in the DropDownList. for instance if you had the list ordered as Category 1, Category 3, Category 2 it would display the items in each grouping in that order top to bottom.

Luke
I know smart components are still in preview but please make this available as soon as you can in the editor component. This would be a HUGE deal!

Need feature parity in the Blazor rich text editor similar to the Angular rich text editor. Need access to add custom schema elements and tag highlighted text with those new schema elements.
https://www.telerik.com/kendo-angular-ui/components/editor/schema/
currently am able to do this with custom Marks in the angular version.
For reasons unknown, our TelerikGrid rows all render with each <tr> element having the "k-alt k-table-alt-row" classes associated with them. This causes the background colour for each row to be the same, rather than alternating between two colours.
For example, the following block of code...
<TelerikGrid Id="@(Utility.CleanCssId("CrewGrid"))"
DetailTemplate="GridDetailTemplate"
EnableLoaderContainer="@ShowLoading"
Groupable="false"
Height="100%"
OnRead="@OnGridRead"
OnStateChanged="@OnGridStateChanged"
OnStateInit="@OnGridStateInit"
Pageable="true"
PageSize="@PageSize"
PageSizeChanged="@OnGridPageSizeChanged"
Reorderable="IsLargeScreen"
Resizable="IsLargeScreen"
SelectionMode="GridSelectionMode.Single"
ShowColumnMenu="IsLargeScreen"
Size="@GetGridSize"
Sortable="true"
SortMode="SortMode.Multiple"
TItem="CrewListItem"
@ref="Grid"
@bind-SelectedItems="@SelectedItems"
OnRowRender="OnRowRender">
<NoDataTemplate>
<strong>@RecordsMessage</strong>
</NoDataTemplate>
<GridSettings>
<GridColumnMenuSettings Lockable="false" FilterMode="ColumnMenuFilterMode.None" />
<GridPagerSettings InputType="PagerInputType.Buttons" PageSizes="@PageSizes" ButtonCount="5" Adaptive="false" Position="PagerPosition.Bottom" />
</GridSettings>
<GridColumns>
<GridColumn Field="@nameof(CrewListItem.Color)"
Width="@(IsLargeScreen ? "40px" : "50px")"
Resizable="false"
ShowColumnMenu="false"
Groupable="false"
ShowColumnChooser="false"
Sortable="false"
HeaderClass="k-text-transparent"
OnCellRender="OnGridCellRender">
<Template>
@{
var item = (CrewListItem)context;
<M360ListColumnColor Color="@item.Color" IsLargeScreen="IsLargeScreen" />
}
</Template>
</GridColumn>
<GridColumn Field="@nameof(CrewListItem.Name)" Title="@TMessages.Crew" OnCellRender="OnGridCellRender" VisibleInColumnChooser="false">
<Template>
@{
var item = (CrewListItem)context;
<div class="k-d-flex k-h-full @(IsLargeScreen ? "k-align-items-stretch" : "k-align-items-center")">
<M360ListColumnLink Url="@string.Concat("crew/", item.Id)" Text="@item.Name" EntityType="Crew" IsPrimary="true" />
</div>
}
</Template>
</GridColumn>
<GridColumn Field="@nameof(CrewListItem.DivisionsJson)" Title="Division(s)" Sortable="true" Visible="IsLargeScreen" OnCellRender="OnGridCellRender">
<Template>
@{
var item = (CrewListItem)context;
<M360ListColumnList Items="@item.Divisions.ToList()" />
}
</Template>
</GridColumn>
.
.
.
</GridColumns>
</TelerikGrid>...results in markup like this...
<tbody class="k-table-tbody" role="rowgroup">
<tr
role="row"
class="k-master-row k-table-row k-alt k-table-alt-row"
data-render-row-index="0"
aria-rowindex="1"
>
. . .
</tr>
<tr
role="row"
class="k-master-row k-table-row k-alt k-table-alt-row"
data-render-row-index="1"
aria-rowindex="3"
>
. . .
</tr>
<tr
role="row"
class="k-master-row k-table-row k-alt k-table-alt-row"
data-render-row-index="2"
aria-rowindex="5"
>
. . .
</tr>
. . .
</tbody>
I can see that the "aria-rowindex" increments by two, yet the "data-render-row-index" increments by one. Are we missing something simple, yet crucial here? What could cause the skipping of rows during render?
Many thanks,
Nem
Sometimes the Gantt provides better visibility when we can split tasks into segments on the same row. This is a new feature to SyncFusion and would be very useful to extend the possibilities of the Telerik Gantt as well.
This is an example of what it looks like:
I could make use of this in a couple of ways. Some of my tasks require to get to a preliminary point at a certain time and a finished point later. Those are not continuous buckets of work, but they are so closely related that it would make visual presentation more intuitive and simpler if they were displayable that way.
I might also use this as a method of displaying a higher level read-only gantt where I want to condense a few milestones or task windows into a single row.
Sometimes we need custom filter logic.
The advised approach currently is to use the OnRead event and have to manage the fetching of data manually https://docs.telerik.com/blazor-ui/components/grid/manual-operations
If we could set a column to use a filter function that has Func<GridDataType, Bool>? then we could apply this complex filter without having to repeatedly query the database and apply filters server side.
For example, if I wanted to filter a column that related to an object that had a property that was a Collection<T> I could check the values of this collection against a filter UI I have made somewhere in the grid or outside of it. Then when the columns filterdescriptior was reviewed it would check my Func which returned True if any of the Rows Collection<T> matched my custom filter UI options.
Example use case that this feature would allow;
We have edit dialogs with editable fields on them, and we want to display a confirmation dialog if the user tries to close the edit dialog without saving. Simplified code to illustrate the issue:
