Issue with Data Form when using Form Group

[Joe Sperlak]

I am experiencing a weird issue with the data form when using a form group.

Here is the code where I'm setting the column count to 2 and column spacing to 20px. There are two fields currently, one a text box and the other a custom component which is just a combo box.

And this is how that renders. Note that not only does the form layout not render properly but the combo box control actually renders as a numeric box with the up down arrows. I'm not allowed to type text characters into it but I can type numbers.

And when I click one of those arrows in the numeric box, the control re-renders as the correct combo box control.

I have another example of the form without the form group and everything loads and runs just fine without any of these issues. When will this be fixed?

Hi Joe Sperlak,

We have included the fix for the issue “Components not rendered properly inside the FormGroup" with our package version “24.2.8”. Therefore, we recommend upgrading to our latest version to resolve the current issue. Kindly check out the updated sample below,

Root cause:

The component does not get re-rendered when using a template within the FormGroup render fragment. Consequently, changes made to the template are only reflected after the component is re-rendered, typically triggered by clicking the submit button. To address this issue we have calling stateHasChanged at the appropriate point after updating the template, you ensure that the component re-renders to reflect the changes immediately rather than waiting for a subsequent event such as clicking the submit button.

This portion now works properly but I am experiencing a different issue with groups.

I have the ColumnCount set to 2 and it applies it to the form groups instead of the fields.

I have a third form group and I get this error when trying to run the code. Even if I update the ColumnCount to 3 it throws the same error.

So I did some testing and was able to get the group column stuff to work after reading through the documentation again but I still get that same error while trying to set up a drop down list of enums.

<FormItem Field="@nameof(CreateAssetDto.WarrantyPeriodInterval)">
    <Template>
        <label class="e-form-label">Warranty Interval</label>
        <SfDropDownList DataSource="@_warrantyPeriodIntervals" TItem="string" TValue="WarrantyInterval?" @bind-Value="@_asset.WarrantyPeriodInterval"></SfDropDownList>
    </Template>
</FormItem>


private string[] _warrantyPeriodIntervals = [];
protected override void OnInitialized()
{
    _warrantyPeriodIntervals = Enum.GetNames(typeof(WarrantyInterval));
}
