Disabling a TelerikgridCheckboxColumn on data load

[Afreen]

Hi,

I am using telerikgrid control to display the employees information. I have telerikgridcheckboxcolumn which is bind to a IEnumerable list of employee who are eligible for promotion.

I am looking for a solution to disable this header checkbox when there is none of the employee is eligible for promotion. 

Please see below my code snippet for Grid and Checkbox:

 

<TelerikGrid Data="ShipmentInfo" SelectionMode="GridSelectionMode.Multiple" SelectedItems="SelectedEmployees" Class="grid-no-scroll" Sortable="true" Size="Telerik.Blazor.ThemeConstants.Grid.Size.Medium" Resizable="true" Pageable="false" Height="55vh" ScrollMode="GridScrollMode.Scrollable" FilterMode="GridFilterMode.None" OnRowRender="@OnRowRenderHandler" SelectedItemsChanged="@((IEnumerable<EmployeeInfoDto> employeess) => SelectedItemsChanged(employees))">

 

<GridCheckboxColumn Title="Allow Promotion" SelectAll="true" CheckBoxOnlySelection="true" HeaderClass="@GetHeaderCssClass()"></GridCheckboxColumn>

 

 private void SelectedItemsChanged(IEnumerable<EmployeeInfoDto> employees)
    {
        // Checkboxes are disabled for shipments that aren't allowed to be routed but we don't want the select all function to select unroutable shipments
        // so remove any unroutable shipments from the given collection and set that to the SelectedItems collection
        SelectedEmployees = employeess.Where(s => s.EligibleForPromotion).ToList();
    }

 

Please can you help get my desired requirement.

Thanks & regards,
