+## Environment
+
+<table>
+ <tr>
+  <td>Product</td>
+  <td>{{ site.product }} Chart</td>

+
+## Description
+
+How can I change {{ site.product }} Chart columns to appear with rounded corners?
+
+## Solution
+
+You can achieve this requirement using the .Visual() capability offered by the component. Check the full implementation in this live REPL sample:
+
+[Chart Example: All Corners Rounded](https://netcorerepl.telerik.com/myPlcPlg30MY8AnT10)

+- **Critical scored issues (CVSS 9.0+):** Resolved within **30 days**.  
+- **High scored issues (CVSS 7.0–8.9):** Resolved within **60 days**.  
+- **Medium or lower scored issues (CVSS < 7):** Resolved within **90–120 days**, depending on the score.

+
+## Description
+
+I want to modify the grouping column in the Scheduler with custom HTML, such as adding a button or a link with the ID of the group.
+
+This KB article also answers the following questions:
+- How can I add a custom button to the Scheduler's group header?
+- Is it possible to insert custom HTML into the Scheduler's grouping template?
+- Can I customize the appearance of the Scheduler's group headers with HTML?
+
+## Solution
+
+To customize the grouping column in the Scheduler with custom HTML, such as adding buttons or links, utilize the [groupHeaderTemplate](https://docs.telerik.com/kendo-ui/api/javascript/ui/scheduler/configuration/group#groupheadertemplate) configuration option. This option allows the insertion of custom HTML content into the group header cells based on specific conditions or for specific resources.
+
+Below is an example demonstrating how to add a custom button to the group header cell for a specific resource using the `groupHeaderTemplate` configuration:
+
+```html
+<script id="groupHeaderTemplate" type="text/x-kendo-template">
+  # if(data.field === "roomId") { #
+  <div style="color: #=color#">#=text#</div>
+  <button>Custom Button</button>
+ #  } else { #
+ <div style="color: #=color#">#=text#</div>
+ # } #
+</script>
+```
+
+In this example, a custom button is added to the group header cell when the grouping is done based on the `roomId` field. You can modify the condition and content as needed to suit your particular requirements.
+
+For a practical implementation of this solution, refer to this [example](https://dojo.telerik.com/MsoTFBhM/3).
