How to customize the TextArea row fields in Blazor DataForm component?

This article provides a guide on how to customize the height of TextArea in Blazor Data Form by setting the rows attribute.

Adjusting TextArea Rows in DataForm

To customize the number of rows in a TextArea field within DataForm, you can use a template feature tailored for the specific field. In this template, the TextBox component is used with the Multiline property set to true. Then, the HtmlAttributes property is used to specify the number of rows for the TextArea. In the example provided below, the rows attribute is set to 5, indicating that the TextArea field will display five rows.

Here is an example code snippet that demonstrates how to implement this in DataForm:

<SfDataForm ID="MyForm"
            Width="100%"
            Model="@EventRegistrationModel">
    <FormValidator>
        <DataAnnotationsValidator></DataAnnotationsValidator>
    </FormValidator>
    <FormItems>
        <FormItem Field="@nameof(EventRegistration.Name)" Placeholder="e.g. Andrew Fuller"></FormItem>
        <FormItem Field="@nameof(EventRegistration.Email)" Placeholder="e.g. [email protected]"></FormItem>
        <FormItem Field="@nameof(EventRegistration.TextAreaField)">
            <Template>
                <SfTextBox Multiline=true @bind-Value="EventRegistrationModel.TextAreaField" HtmlAttributes="@(new Dictionary<string,object>() { { "rows", 5 } })"></SfTextBox>
            </Template>
        </FormItem>
    </FormItems>
</SfDataForm>
