+# Troubleshooting
+
+This article provides solutions to common issues that you might come across when leveraging the Telerik UI for {{ site.framework }} DropDownList.
+
+## Items return as undefined when configuring the DropDownList for Remote Binding
+
+By default, the {{ site.framework }} predominantly configures the JSON property naming convetion for server responses to `camelCase`. Where the DropDownList relies on `PascalCase` formatted response instead.
+
+The following example demonstrates the differences between the format of responses.
+
+```PascalCase
+[
+    {
+        "Value": "1",
+        "Text": "Option1"
+    },
+    {
+        "Value": "2",
+        "Text": "Option2"
+    }
+]
+```
+```camelCase
+[
+    {
+        "value": "1",
+        "text": "Option1"
+    },
+    {
+        "value": "2",
+        "text": "Option2"
+    }
+]
+```
+
+### Solution
+
+To handle Pascal-Cased formatted responses, alter the default JSON property naming convention by using the available [JSON Serialization Options](https://docs.telerik.com/aspnet-core/installation/json-serialization#json-serialization).
+
+
+```C#
+builder.Services
+            .AddControllersWithViews()
+            .AddJsonOptions(options => {
+                options.JsonSerializerOptions.PropertyNamingPolicy = null;
+            });
+```
