This article explains how to update the progress bar value when submitting in Blazor Progress Bar.

Update Progress Bar Value in the OnValidSubmit Method

Blazor Progress Bar provides an option to update progress bar value in the OnValidSubmit method.

To update the progress bar value in the OnValidSubmit method, you need to invoke the “StateHasChanged” method when updating the progress bar’s in-between values.

The below code example demonstrates how to update progress bar value in the OnValidSubmit method.

Index.razor

@using Syncfusion.Blazor.ProgressBar
@using Syncfusion.Blazor.Buttons

<EditForm Model="@model" OnValidSubmit="@OnValidSubmit">

   <div class="submit-btn">

       <SfButton type="submit" style="color: Black; text-transform: capitalize;">Submit</SfButton>

   </div>

   <SfProgressBar Type="ProgressType.Linear" Height="40" CornerRadius="CornerType.Round" Width="100%" ShowProgressValue="true" Value="@ProgressValue" Minimum="0" Maximum="100" Visible="@Visible">
   </SfProgressBar>

</EditForm>

@code{
   public int ProgressValue { get; set; }
   public bool Visible { get; set; } = false;
   public UserProfileModel model { get; set; } = new UserProfileModel();

   public class UserProfileModel
   {
       public string Name { get; set; }
       public string Email { get; set; }
   }

   async Task OnValidSubmit()
   {
       this.Visible = true;
       this.ProgressValue = 10;

       this.ProgressValue = 20;
       StateHasChanged();

       await Task.Delay(5000);
       this.ProgressValue = 50;
       StateHasChanged();

       await Task.Delay(5000);
       this.ProgressValue = 70;
   }
} 

The following screenshot illustrates the output of the code snippet.
