Setting the RadzenDataGridColumn.OrderIndex property in my page's Razor template does not have an effect. Here's my code sample:

<RadzenDataGrid TItem="Employee" Data="@EmployeesList" AllowSorting="true">
    <Columns>
        <RadzenDataGridColumn Title="Last Name" TItem="Employee" Property="LastName" OrderIndex="1" />
        <RadzenDataGridColumn Title="First Name" TItem="Employee" Property="FirstName" />
        <RadzenDataGridColumn Title="Title" TItem="Employee" Property="Title" />
    </Columns>
</RadzenDataGrid>

When the data is set, the LastName column is not ordered. Even the official DataGrid column reorder example page sets this property and it doesn't take effect.

To Reproduce
Heck, visit the official DataGrid column reorder page. It sets OrderIndex to the LastName and FirstName columns, but the columns are not being ordered! Am I missing something?

You need to set OrderIndex to other columns as well otherwise the grid will keep the declared columns order.

Oooh, I see I misinterpreted the meaning of the OrderIndex property. I was under the impression that it affects the ordering of the rows (sort by last name, then by first name, etc.). I now understand that it actually determines the order in which the columns are displayed from left to right.

There doesn't seem to be a way to set the DataGrid to be initially sorted based on one specified column.
