Hi Ferris,

Can you please make sure you are using the latest version of Smart.Blazor? If yes, please also share all properties you have set to the Grid.

In the example below you can see that the code you shared should be working correctly:

@page “/”

<Grid @ref=”grid” DataSource=”@Clients” ColumnGroups=”@columnGroups”>
<Columns>
<Column DataField=”Name” Label=”Client Name” ColumnGroup=”Details”></Column>
<Column DataField=”Balance” Label=”Acccount Balance” DataType=”number”
ColumnGroup=”Details”></Column>
<Column @ref=”cityColumn” DataField=”City” Label=”City” ColumnGroup=”Address”></Column>
<Column DataField=”Country” Label=”Country”
ColumnGroup=”Address”></Column>
<Column DataField=”LastOrder” Label=”Last Order” DataType=”date” CellsFormat=”dd/MM/yyyy”
Align=”HorizontalAlignment.Center”></Column>
</Columns>
</Grid>

<Button OnClick=”FreezeColumn”>Freeze City</Button>
<Button OnClick=”UnfreezeColumn”>Unfreeze City</Button>

@code{
Grid grid;
Column cityColumn;

private void FreezeColumn()
{
cityColumn.ColumnGroup = “Frozen”;
cityColumn.Freeze = “near”;
}

private void UnfreezeColumn()
{
cityColumn.ColumnGroup = “Address”;
cityColumn.Freeze = “false”;
}

class Client
{
public string Name { get; set; }
public double Balance { get; set; }
public string City { get; set; }
public string Country { get; set; }
public DateTime LastOrder { get; set; }

public Client(string name, double balance, string city, string country, DateTime lastOrder)
{
Name = name;
Balance = balance;
City = city;
Country = country;
LastOrder = lastOrder;
}
}
Client[] Clients = new Client[]
{
new Client(“Maria Anders”,130.00,”Berlin”, “Germany”, DateTime.Now),
new Client(“Ana Trujillo”,230,”Mxico D.F.”, “Mexico”, DateTime.Now),
new Client(“Antonio Moreno”,-3500,”Mxico D.F.”, “Mexico”, DateTime.Now),
new Client(“Thomas Hardy”,55,”London”, “UK”, DateTime.Now),
};

List<GridColumnGroup> columnGroups = new List<GridColumnGroup>()
{
new GridColumnGroup()
{
Label = “Customer Details”,
Align = HorizontalAlignment.Center,
Name = “Details”
},
new GridColumnGroup()
{
Label = “Customer Address”,
Align = HorizontalAlignment.Center,
Name = “Address”
},
new GridColumnGroup()
{
Label = “Frozen”,
Align = HorizontalAlignment.Center,
Name = “Frozen”
}
};
}
