Please add a feature to export the grid to a PDF file.

---

ADMIN EDIT

We have made two examples you can use for the time being to get a PDF document from the grid:

• server-side export - getting the grid data request and using some application code to generate the file: https://github.com/telerik/blazor-ui/tree/master/grid/pdf-export-server
• client-side export through Kendo libraries in the browser only: https://github.com/telerik/blazor-ui/tree/master/common/pdf-jpg-export-js

Is there any way to default the values that are used when I create a new row?

So for example, I have a row where I want to default a date to Jan 1st of the following year.  However, when I add the row, it adds nulls to all fields and the date shows up as 1 Jan 1900 and there's a lot of fiddly clicking to set the right date.

ADMIN EDIT: The following knowledge base article has been updated to explain how to use nested models: https://docs.telerik.com/blazor-ui/knowledge-base/grid-bind-navigation-property-complex-object

At the moment, you must use flat models with primitive types for binding the grid. If you don't, the data source operations break and they can't even display "nested" values. Examples here and here.

I would like to be able to use my complex models so I can point a grid's column to a field like MyModel.MyNestedModel.MyPrimitiveField

My be related to binding to a data table and dynamic expando.

Please allow to set Group By fields at Design time, currently only user has control to Drag and drop to group.

we need feature to group by fixed set of columns and don't allow user to change the grouping, also need option to hide group collapse icons.

Grid column header and content alignment (horizontal +Vertical)

ADMIN EDIT

For the time being, this is possible through the CellRender event, see below in the thread for an example.

Steps to reproduce:
1.Create a Telerik Grid with SelectionMode=@GridSelectionMode.Multiple and a GridCheckboxColumn to select/unselect the rows. 
Also, bind the selected items to an IEnumerable collection and display the selected items in a <ul>
2.Click on Row1's checkbox - It selects the row, but not checking the checkbox
3.Click on it again- Now it unselects the row, but the checkbox is checked.
4.Click on the SelectAll checkbox in the grid header - It selects all rows, row checkboxes are checked, but the SelectAll checkbox in the grid header remains unchecked.
5.Click on the SelectAll checkbox again - All rows remain selected, row checkboxes remain checked, The SelectAll checkbox is now checked.
6.Click on the SelectAll checkbox again- All rows are unselected, row checkboxes are unchecked, The selectAll checkbox remains checked.

Another issue is, corresponding row checkbox remains checked on moving to next page eventhough the row is not selected. 
For eg,
1. a grid of 20 rows displays 10 items per page; Row 2 is selected and checkbox is checked
2. Move to page 2 - Row 12 checkbox is checked (but row 12 is not selected)

Please note that this discrepancy is only when using a checkbox column, otherwise the grid selection using Ctrl + Click works as expected.

Attached Screenshot of one of the issues

On clicking Row 2 checkbox again, result below

Hello,

I am new to your Blazor UI components.  Please provide a link for exporting a grid to excel.

Thanks,

Earl

How would you remove the icon to expand a detail grid only for certain rows?  Some rows will not have detail data and should not be expandable.

ADMIN EDIT

As suggested by Joel, you can use the RowRender event and a bit of CSS to hide the button. Here is a Knolwdge Base article that shows a fully runnable sample: https://docs.telerik.com/blazor-ui/knowledge-base/grid-conditional-expand-button.

    void OnRowRenderHandler(GridRowRenderEventArgs args)
    {
        OrgUnit item = args.Item as OrgUnit;

        args.Class = item.Children.length ? "has-children" : "no-children";
    }

tr.no-children .k-hierarchy-cell *{
    display:none !important;
}

Because the shape of our business objects is not something your grid is easily bound to, we are attempting to generate ExpandoOjbects on the fly and bind to them.  In the picture below you can see that Id is not binding correctly.  Name is showing up because a column Template was used and that seems to work fine.  However, when attempting to use an EditorTemplate we get the RuntimeBinderException shown below.

Hi,

I cant see what it is that's causing this error. evertime i run my app, i get the follwoing error below:

An unhandled exception occurred while processing the request.

Microsoft.AspNetCore.Components.Reflection.ComponentProperties.ThrowForUnknownIncomingParameterName(Type targetType, string parameterName

My Code:

@page "/Table"

@inject IPurchaseOrderRepository purchaseOrderRepository
@using Telerik.Blazor.Components.Grid
    <h3>Table</h3>

<TelerikGrid Data=@auditEventTypeDTOs>
    <TelerikGridColumn Field="AuditEventName">

    </TelerikGridColumn>
</TelerikGrid>


@code{



    public IEnumerable<AuditEventTypeDTO> auditEventTypeDTOs { get; set; }

    protected override async Task OnInitializedAsync()
    {
        auditEventTypeDTOs = await purchaseOrderRepository.GetAllAuditEventTypes();
    }

}

The IEnumerable object 'auditEventTypeDTOs' is getting the data from the repository and i've made sure that i don't have any component with the same name within Telerik.blazor namespace.

Do let me know if you need me me to supply more information.

many thanks in advance

George.

The need is to update, add or delete a lot of items at once (for example, the selected items). Sample of batch editing: https://demos.telerik.com/kendo-ui/grid/editing.

Perhaps this may become possible through methods on the grid that invoke the CUD operations.

---

ADMIN EDIT

There is a sample project that accomplishes most of these goals: https://github.com/telerik/blazor-ui/tree/master/grid/batch-editing

The grid state offers a great deal of flexibility in terms of controlling the grid, up to putting it in edit/insert mode.
