Hi Frank,
Thanks for contacting Syncfusion support.
Query: “When you select a row in the first datagrid, the description text is updated correctly, but the second datagrid is not updated.”
We have analyzed the reported query and we understand that you are facing issue when trying to filter the Grid data by changing the parameters in Url string. Instead of changing the parameters in the URL string, we request you to use Query property of Grid to filter the detail Grid datasource.
Refer the below code example.
|
<SfGrid TValue="Order" AllowPaging="true">
<GridPageSettings PageSize="4"></GridPageSettings>
<GridEvents RowSelected="RowSelecthandler" RowDeselected="Deselected" TValue="Order"></GridEvents>
<GridColumns>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
</GridColumns>
</SfGrid>
<h4>Kostenstellen des Geschaeftsfeldes: @AbteilungBez</h4>
<SfGrid TValue="Customer" Query="@Qry" AllowPaging="true">
<GridPageSettings PageSize="5"></GridPageSettings>
Adaptor="Adaptors.ODataV4Adaptor">
</SfDataManager>
<GridColumns>
</GridColumns>
</SfGrid>
@code
{
public Query Qry { get; set; }
public class Order
{
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
public class Customer
{
public string CustomerID { get; set; }
public string Address { get; set; }
}
public string AbteilungBez { get; set; }
public void RowSelecthandler(RowSelectEventArgs<Order> args)
{
Qry = new Query().Where("CustomerID", "equal", args.Data.CustomerID);
AbteilungBez = args.Data.CustomerID;
}
public void Deselected(RowDeselectEventArgs<Order> Args)
{
Qry = new Query() { };
}
