Hello,
I have updated Blazor UI to the latest version (2.9.0) and some of my controls lost their state.
Let me explain:
I have a page with 4 tabs (TelerikTabStrip), if i choose the value of a dropdown (TelerikDropDown) in the first tab and move to the second tab and then come back to the first tab, the value would be lost and the dropdown is empty however, if i put a breakpoint and look at the model, it shows that the value is still preserved.
Is there something i am missing? is this an update gone wrong (on my side)?
I have downgraded back to 2.8.0 and it works as expected.
Thanks.
Using your tree view live sample, filter the list with "1", then try to expand "Test1" - crash.
I would expect "Test1" to apprear in the list but without the expandable icon or the expandable icon does nothing when clicked
According to the doc (https://docs.telerik.com/blazor-ui/components/grid/columns/width),
"When all column widths are explicitly set and the cumulative column width is greater than the available Grid width, a horizontal scrollbar appears and all set column widths are respected."
I have a grid with a width of 1500px and a cumulative column width of 1750 pixels:
<TelerikGrid Data="@datos"The horizontal scroll bar appears all right, but the column widths are not respected. As shown in the image, the columns on the right are squeezed
Any clues?
Thanks in advance
When a content is displayed in TelerikWindow and a TelerikTreeView`s item is expanded, the item`s content is above the window one due to higher z-index.
To fix it, use this CSS:
/* Telerik window content (with z-index 10001) above their animation container (with z-index 10002, used for example in tree view) */Now we can expand/collapsed tree view item using bound read/write model property.
We need to bind read-only property or controll expandability outside of tree view.
Examples:
Thank you

What kind of magic updates the actual database?
privatevoidUpdateItem(GridCommandEventArgs args)
{
var argsItem = args.ItemasProductBindingModel;
var index =GridData.FindIndex(i => i.ProductId== argsItem.ProductId);
if(index !=-1)
{
GridData[index]= argsItem;
}
}"
<TelerikDropDownList Data="@myDdlData" TextField="MyTextField" ValueField="MyValueField" @bind-Value="@SelectedValue" Width="100%" />
public string SelectedValue { get; set; }
public class MyDdlModel
{
public int MyValueField { get; set; }
public string MyTextField { get; set; }
}
protected IEnumerable<MyDdlModel> myDdlData = Enumerable.Range(1, 20).Select(x => new MyDdlModel { MyTextField = "item " + x, MyValueField = x });
Hello,
im trying to render a treview but its not showing any item, im also print the results of my query on a table using a for loop and it shows the results ok , but the trevieww its not loading any data. Attached my code :
@inherits LayoutComponentBaseGrid errors with both filtering and a detail template:
<Telerik.Blazor.Components.TelerikGrid Data="@GridData" FilterMode="Telerik.Blazor.GridFilterMode.FilterRow">
<GridColumns>
<Telerik.Blazor.Components.GridColumn Title="Name" Filterable="true" Field="@nameof(GridItem.Name)"></Telerik.Blazor.Components.GridColumn>
<Telerik.Blazor.Components.GridColumn Field="@nameof(GridItem.Id)" Filterable="true" Title="Id"></Telerik.Blazor.Components.GridColumn>
</GridColumns>
<DetailTemplate>
<div>Custom Template</div>
</DetailTemplate>
</Telerik.Blazor.Components.TelerikGrid>
@code {
List<GridItem> GridData { get; set; } = new List<GridItem>();
protected override void OnInitialized()
{
GridData = GenerateData();
}
private List<GridItem> GenerateData()
{
List<GridItem> data = new List<GridItem>();
for (int i = 0; i < 5; i++)
{
GridItem mdl = new GridItem { Id = i, Name = $"Name {i}" };
data.Add(mdl);
}
return data;
}
public class GridItem
{
public int Id { get; set; }
public string Name { get; set; }
}
}
The grid renders correctly with either the DetailTemplate or FilterMode, but not both.

As a developer user, I need to add a Markdown Editor control to my Blazor UI application so that I can capture and display markdown-compliant text input.
Thanks

In a Telerik Grid, we had just implemented the new Grid Footer Template. However, any built-in filtering (filterrow, filtermenu, searchbox) we use now will cause the grid/page to crash when the input we type does not exist for any row in the grid. If the input we type does exist, the filtering works correctly. For instance, if wanted to filter the name "John Smith" and a row exists with that name, then that row will be filtered. If we typed in "John Smithasdf", then the grid crashes and we receive the following message from the DevTools window:
blazor.server.js:19 [2020-09-21T16:58:12.070Z] Error: System.InvalidOperationException: Nullable object must have a value.
at System.Nullable`1.get_Value()

From the highlighted text, we deduced the issue had to deal with the Grid Footer template. Not all of our columns are aggregated on the footer row, so we were thinking that's what the "Nullable object must have a value" message meant. When we removed the Grid Footer template, the filtering worked correctly. With one of our other grids, we added a temporary footer grid, and the same crash would occur.
Is there a work-around for this? The footer template otherwise is great, and we would like to use both that and filtering on our grids. Please let us know if you need any more info.
Thanks,
Steve
In our application, we have the need for aggregate functions in the grid which are determined at runtime, not design time. We were able to get this working for Group footers using a combination of the GroupFooterTemplate element and determining the applicable aggregates in OnStateInit and OnStateChanged. When our team saw that the FooterTemplate element was added, we were excited to bring "Grand Summary" functionality to this grid on top of the existing group summaries. As far as we have been able to determine, however, there doesn't appear to be a way, currently, to add AggregateDescriptors dynamically for the entire grid like we can for groups. We can do the aggregate operations manually against the data source, but this doesn't take into account and filtering which is applied to the grid. We have been unable to find any way of adding AggregateDescriptors for the overall Grid like we can for groups within the GridState's GroupDescriptor property.
Attached are two files: StateInitializationC#Code and gridRazor.txt, which contain relevant snippets of what we are currently doing.
Hello team;
Can you please tell us in what version or approximate time of arrival of the new Toolbar?
Suggestion: It would be helpful if the roadmap list is sorted by "In progress" status. This way we can plan accordingly.
Thanks!
