  Hi,

  Migrate from 2010v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.
  
  Using C1InputDate from C1.Web.Wijmo.Controls.48.dll
  
  Changes C1DateInput to C1InputDate control.

  Before, Date property for C1DateInput can be not null
  
  Now, Date can be nullable

  I update txtToDateTime.Date, but not shown in page:

  

  1053×287 17.5 KB

  My code, in method for search. GridView in updatePanel,
  
  InputDate controls OUT of updatePanels. Search Button is within updatePanel
  
  I try use c1inputdate in javascript, but not working. It’s not shows value in control

  string fechaHasta = string.Empty;
    string fechaDesde = string.Empty;
  
    DateTime dateA;
    DateTime dateB;
  
  
    if (!txtToDateTime.Date.HasValue)
    {
        txtToDateTime.Date = DateTime.Now;
  
        var dateString = txtToDateTime.Date.Value.ToString("dd/MM/yyyy");
  
        ScriptManager.RegisterStartupScript(
            this,
            GetType(),
            "refreshC1Date" + Guid.NewGuid(),
            $"$('#{txtToDateTime.ClientID}').c1inputdate('option', 'value', '{dateString}');",
            true
        );
    }
    
  
    fechaDesde = txtFromDateTime.Date.Value.ToShortDateString() + " 12:00 am";
    fechaHasta = txtToDateTime.Date.Value.ToShortDateString() + " 23:59 pm";
  
    dateA = Convert.ToDateTime(fechaDesde);
    dateB = Convert.ToDateTime(fechaHasta);

  Markup aspx

  <cli:C1InputDate ID="txtToDateTime" runat="server" Width="105px"

  var jsDate = date.ToString(“yyyy-MM-dd”);

  Not works “dd/MM/yyyy”

  C1InputDatehas

  DateFormat="dd/MM/yyyy" Culture="Spanish (Peru)"

  public static class C1Helpers
  {
      public static void SetC1InputDate(Page page, C1.Web.Wijmo.Controls.C1InputDate ctl, DateTime? value)
      {
          var date = value ?? DateTime.Today;
          ctl.Date = date;
  
          var jsDate = date.ToString("yyyy-MM-dd");
  
          var script = $@"
              (function() {{
                  var d = new Date('{jsDate}');
                  $('#{ctl.ClientID}').c1inputdate('option', 'date', d);
              }})();
          ";
  
          ScriptManager.RegisterStartupScript(
              page,
              page.GetType(),
              "setC1Date_" + Guid.NewGuid(),
              script,
              true
          );
      }
  }

  Hi,

  We tested your code and observed that the date was not being updated on the page. Additionally, when the code executed on startup, it resulted in an error shown in the browser’s console.

  To resolve this, we updated the code in the Default.aspx.cs file of the attached project. With these changes, the project runs correctly, and the date is properly updated in the C1InputDate control.

  If the issue persists, please update this sample project to demonstrate it, so we can investigate further.

  Update the code, add a button an click:
  
  not update value for inputdate:

          protected void btnTest_Click(object sender, EventArgs e)
          {
  			var dateString = DateTime.Now.AddDays(-5).ToString("dd/MM/yyyy");
  
  			string scriptCode = $"$(function() {{ $('#{txtToDateTime.ClientID}').c1inputdate('option', 'value', '{dateString}'); }});";
  
  			ScriptManager.RegisterStartupScript(
  				this,
  				GetType(),
  				"refreshC1Date" + Guid.NewGuid(),
  				scriptCode,
  				true
  			);

  Hi,

  We updated the ASPX markup to include a test button. On the button’s click event, we executed the same code as shown in your snippet. Unfortunately, we were unable to reproduce the issue you described and the date refreshes correctly on our end.

  We have attached a video and the updated sample project for your reference - C1InputDateNullable_Updated.zip, Sample_Behavior.zip

  If you continue to experience the issue, please share an updated sample project that reproduces it so we can investigate further and assist you better.

  Best Regards,
