Would be nice to have an Expansion Panel like this one:

Hi!

I want to create a grid with multiselect options (controlled by checkboxes in the first column). I have used code from https://demos.telerik.com/blazor-ui/grid/selection but when i try this code in my project there are no checkboxes in the first column, just empty cells. Am i the only one with this problem?  

Hi,

Any information on when the Layout Components available in AspNetCore will be available in Blazor?

I am currently putting a proposal together to purchase Telerik for Blazor and could really use some of those components to enhance the application than relying on 3rd-Party integrations.

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:

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:

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:

• Expand tree view item when IsActive read-only model property is true
• Expand/collapse all tree items with a button click

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;

}

}"

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 :

Grid 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.

Overview

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.

Acceptance criteria

• The editor control supports rich WYSIWYG editing with support for standard markdown styling including: headers, emphasis, lists, images, links, blockquotes and inline code.
• The editor control supports raw markdown editing mode, as well as WYSIWYG (preview) mode.
• The editor control supports raw markdown output and HTML output.

Bonus criteria

• A paired Markdown Display control supports presentation of markdown as HTML (so that developers can store markdown in a database, for example, and convert to HTML on the client for display.

• When I close Modal - Popup or Save button is clicked not able to Re-Load or Refresh the grid or Parent component
• I am calling the Save Action in Modal-Popup page and not using EventCallback method
• In Parent component, I am loading the Grid. But in Modal-Popup when calling Save Action the Grid or Parent component not refreshing.

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()
   at BudgetPak.Pages.User.Budgeting.HeadcountReview.<>c__DisplayClass0_4.<BuildRenderTree>b__43(RenderTreeBuilder __builder4)
   at Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder.AddContent(Int32 sequence, RenderFragment fragment)
at Telerik.Blazor.Components.Grid.GridFooterCell`1.BuildRenderTree(RenderTreeBuilder __builder)
   at Microsoft.AspNetCore.Components.Rendering.ComponentState.RenderIntoBatch(RenderBatchBuilder batchBuilder, RenderFragment renderFragment)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.RenderInExistingBatch(RenderQueueEntry renderQueueEntry)
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.ProcessRenderQueue()

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
