Label and tooltip error message not displaying in SfGrid dialog for complex field
Hi,
I have the following two classes.
public class Container
{
[Required(ErrorMessage = "Barcode must be specified.")]
public string Barcode { get; set; }
[Required(ErrorMessage = "Container Type must be specified.")]
public int? ContainerTypeId { get; set; }
public ContainerType? ContainerType { get; set; }
}
public class ContainerType
{
public int Id { get; set; }
public string Code { get; set; }
public string Description { get; set; }
}
I am showing details of Containers in an SfGrid, with full CRUD facilities, and an SfDropDownList for the ContainerType column.
<SfGrid TValue="Container" Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Search" })" AllowSorting="true" AllowResizing ="true">
<SfDataManager AdaptorInstance="@typeof(CustomAdaptor)" Adaptor="Adaptors.CustomAdaptor"></SfDataManager>
<GridEditSettings AllowAdding="true" AllowDeleting="true" AllowEditing="true" ShowDeleteConfirmDialog="true" Mode="EditMode.Dialog">
</GridEditSettings>
<GridColumns>
<GridColumn Field=@nameof(Container.Barcode) Width="30%" HeaderText="Barcode" IsPrimaryKey="true" ValidationRules="@(new ValidationRules{ Required=true})" TextAlign="TextAlign.Left"></GridColumn>
<GridColumn Field="ContainerType.Description" Width="70%" HeaderText="Container Type" EditType="EditType.DropDownEdit" TextAlign="TextAlign.Left">
<EditTemplate>
<SfDropDownList DataSource="@ContainerTypes" TItem="ContainerType" TValue="int?" @bind-Value="@((context as Container).ContainerTypeId)">
<DropDownListFieldSettings Text="Description" Value="Id"></DropDownListFieldSettings>
</SfDropDownList>
</EditTemplate>
</GridColumn>
</GridColumns>
</SfGrid>
All this works fine and I can create, update and delete containers. The only issue is that the dialog does not show the label for the Container Type, nor does it show the 'Required' error message for the Container Type field (although it does give the combobox a red border).
Can you see why this would be happening? Can you confirm if I am specifying the DropDownList column correctly?
Hi, thanks for this. It very nearly works as required.
The one outstanding issue is that the actual error message for the complex type is being ignored.
In the sample program that you sent, the error message for the ContainerType.Description field was set to "First name should not be empty". However, the error message shown by the dialog looks to be a standard generic message - "This field is required".
Is there a way to get the defined error message to show?
