+## Description
+
+I need to prevent users from creating new database connections in the Web Report Designer's SqlDataSource component while still allowing them to select from pre-configured existing connections.
+
+## Solution
+
+To stop users from creating new SQL database connections, use a middleware to intercept the `/api/reportdesigner/connectionspermissions` request and modify the response. By returning an empty JSON or an object with all values set to `false`, you can disable the "Build new data connections" option.
+
+````C#
+app.Use(async (context, next) =>
+{
+    if (context.Request.Path.Equals("/api/reportdesigner/connectionspermissions"))
+    {
+        context.Response.ContentType = "application/json";
+        await context.Response.WriteAsync("{}"); // Return empty JSON to disable "Build new connections".
+        return;
+    }
+
+    await next();
+});
+````
