+## Description
+
+In scenarios where you want to display only the names of resources in the RadGantt control without the accompanying percentage values, you might find the default format (e.g., Charlie [100%]) not suitable for your needs. This article provides a solution to remove the percentage values from the resource list, showing only the resource names.
+
+This knowledge base article also answers the following questions:
+- How can I customize the resource list display in RadGantt for ASP.NET AJAX?
+- Is it possible to exclude percentage values from RadGantt's resource list?
+- What client-side approach can be used to modify the RadGantt resource list format?
+
+## Solution
+
+To achieve the removal of percentage values from the resource list in RadGantt for ASP.NET AJAX, use the following client-side JavaScript code. This script should be added to your page where the RadGantt control is used. It utilizes the `OnClientLoad` event of the RadGantt control to modify the display of resource names after the control is fully rendered.
+
+````aspx
+        <script>
+            function OnClientLoad(sender, args) {
+                document.querySelectorAll('table.k-selectable td[role="gridcell"]:nth-child(2)').forEach(cell => {
+                    cell.textContent = cell.textContent.replace(/\s?\[\d+\s?%\]/g, ''); // Remove percentage part
+                });
+            }
+</script>
+        <telerik:RadGantt RenderMode="Lightweight" runat="server" ID="RadGantt1" OnClientLoad="OnClientLoad" ...
+````
+
+- Ensure the RadGantt control includes the `OnClientLoad="OnClientLoad"` attribute to trigger the JavaScript function after the control is loaded.
+- This JavaScript function searches for all cells (`<td>`) in the second column of the resource list, which contain the resource names and percentage values. It then uses a regular expression to remove the percentage part.
+- After applying this script, only the resource names will be displayed in the resource list of the RadGantt control, omitting the percentage values.
