+```csharp
+if (!string.IsNullOrEmpty(tempSearchText))
+{
+    if (this.SearchType == SearchType.StartsWith)
+    {
+        if (!(bool)CaseSensitiveSearchCheckBox.IsChecked)
+            regex = new Regex("^(" + tempSearchText + ")", RegexOptions.IgnoreCase);
+        else
+            regex = new Regex("^(" + tempSearchText + ")", RegexOptions.None);
+    }
+    else if (this.SearchType == SearchType.EndsWith)
+    {
+        if (!(bool)CaseSensitiveSearchCheckBox.IsChecked)
+            regex = new Regex("(" + tempSearchText + ")$", RegexOptions.IgnoreCase);
+        else
+            regex = new Regex("(" + tempSearchText + ")$", RegexOptions.None);
+    }
+    else
+    {
+        if (!(bool)CaseSensitiveSearchCheckBox.IsChecked)
+            regex = new Regex("(" + tempSearchText + ")", RegexOptions.IgnoreCase);
+        else
