+## Description
+
+In this tutorial, we will demonstrate how to insert a new message at a specific index in the RadChat control.
+
+## Solution
+
+To insert a message at a specific index in RadChat, use the `Insert()` method with a `BaseChatDataItem`. Follow these steps:
+
+1. Access the existing messages in RadChat using the `MessagesViewElement.Items` collection.
+2. Create a `ChatMediaMessage` or another appropriate message type.
+3. Convert the message into a `BaseChatDataItem` using the `ChatFactory.CreateDataItem()` method.
+4. Use the `Insert()` method to place the new message at a specific index.
+
+Here is an example:
+
+````C#
+
+private void InsertMediaMessageAtBeginning()
+{
+    ChatMediaMessage mediaMessage = new ChatMediaMessage(Properties.Resources.AndrewFuller, new Size(300, 200), null, this.radChat1.Author, DateTime.Now);
+    BaseChatDataItem baseChatDataItem = this.radChat1.ChatElement.ChatFactory.CreateDataItem(mediaMessage);
+    this.radChat1.ChatElement.MessagesViewElement.Items.Insert(0, baseChatDataItem);
+}
+
+````
