RadzenTemplateForm with Name property

mpolazzo · January 15, 2024, 9:00am

Hi Radzen Team,
I have two RadzenTemplateForm in the same page. When submitting one of the two, I get an error saying that @formname is not set.
Could it be possible to have in one of the next releases a FormName or simply a Name property that could be sent as @formname during the submit (in my case POST...) operation ?
Thanks

Not sure what is @formname, can you clarify? There isn't such code in our component:

github.com

radzenhq/radzen-blazor/blob/master/Radzen.Blazor/RadzenTemplateForm.cs#L250


      
              }
          }
          
          /// <inheritdoc />
          protected override string GetComponentCssClass()
          {
              return "rz-form";
          }
          
          /// <inheritdoc />
          protected override void BuildRenderTree(RenderTreeBuilder builder)
          {
              if (Visible)
              {
                  if (EditContext != null)
                  {
                      builder.OpenRegion(EditContext.GetHashCode());
                  }
          
                  builder.OpenElement(0, "form");
                  builder.AddAttribute(1, "style", Style);

Sure, I understand, but when I have two forms in the same page, a unique Name should be set otherwise it will raise an error:
the post request does not specify which form is being submitted. to fix this, ensure <form> elements have a @formname attribute with any unique value.
I suppose this is due to the underlying <form> that you have in the RadzenTemplateForm wrapper.
Thanks

Hi @mpolazzo,

RadzenTemplateForm does not support this case because the required API is internal. I've logged an issue with Microsoft today.

hi @korchev , I have seen the answer from Microsoft in the ticket you raised.
Is this FormMappingContext that he mentions in the answer something that we can use directly or is it something that you must implement and expose inside RadzenTemplateForm ?
Thanks a lot for your support.

We haven't investigated that further and don't know if FormMappingContext would help or not. You are welcome to try it with the Radzen.Blazor source code and submit a pull request if you make it work.
