  Hi,

  Migrate from 2012v1 to 2025v2 399 in ASP.NET WebForms NET Framework 4.8.1.

  Using C1GridView from C1.Web.Wijmo.Controls.48.dll

  Only I need changes C1Functions overrides legacy javascript code:

  
      <script src="<%= Page.ResolveClientUrl("~/js/C1Functions_Override.js") %>" type="text/javascript"></script>
      

  the legacy code:

  if(C1.Web.UI.Controls.C1GridView)
  {
      C1.Web.UI.Controls.C1GridView._RangeSelectionHelper.prototype.$F = function(c) {
          this.$7 = this.$1.get_$3_58().$1B(true);
          var b = C1.Web.UI.Utils.Measurement.getMousePointerPosition(c.rawEvent);
          var a = (c.target) ? c.target.tagName.toLowerCase() : "";
          if (this.$1.get_enabled() && (this.$1.get_selectionMode()) && (a === "" || ((a === "td" || a === "th") && Sys.UI.DomElement.containsCssClass(c.target, "XXXXX")) || (a === "div" && Sys.UI.DomElement.containsCssClass(c.target, "contentdiv"))) && (b.x > this.$7.x && b.x < this.$7.x + this.$7.width) && (b.y > this.$7.y && b.y < this.$7.y + this.$7.height)) {
              this.$13();
              this.$B = new Sys.UI.Point(b.x, b.y);
              this.$8 = this.$15(this.$B)
          }
      }
      
      C1.Web.UI.Controls.C1GridView.C1GridView.prototype.initialize = function() {
          this.$3_61(false);
          this.get_columns().traverse(Function.createDelegate(this, this.$3_78), null);
          this.$3_5D();
          this.$3_5C();
          this.get_columns().traverse(Function.createDelegate(this, this.$3_7A), null);
  

  In a custom control, C1Window1.$3_72

          var windowReady = function () {
          return controls.C1Window1 && controls.C1Window1.$3_72;
      }

  Can you help me, please, about C1 functions override legacy ?

  Hi,

  This appears to be a very old functionality, and currently we do not have any information or references related to it. Because of this, we are not sure what these functions were originally used for.

  These functions are not available in the current version. If you have any documentation, sample code, or references, please share them so that we can better understand the requirement.

  Please note that ASP.NET WebForms is now considered a legacy platform, and there is no active development ongoing for it. Additionally, you are upgrading from a very old version, which typically requires reimplementing several features from scratch.

  Therefore, we strongly recommend considering a migration to ASP.NET MVC to take advantage of the latest features, improvements, and full product support.

  You can refer to the following documentation for more details:
  
  https://developer.mescius.com/componentone/docs/mvc/online-mvc/overview

  Thanks for your understanding.

  Kind Regards,
  
  Aastha
