  I’m trying to access a toolstrip button in windows forms using  button name in windows forms but facing null reference exception as end result. Normally I can access button using its name, but i am facing issue in accessing the  button in toolstrip. This issue occur in N unit framework and access button using automation element. Can  anyone guide me for this issue ?
  
      
  Code snippet for accessing button:
  
      enter code here
          public static AutomationElement WindowElement;
          public  void ClickButton()
          {
              object objPattern;
              AutomationElement click = WindowElement.FindFirst(TreeScope.Descendants,
               new PropertyCondition(AutomationElement.NameProperty, "toolStripButton2"));
              click.TryGetCurrentPattern(InvokePattern.Pattern, out objPattern);
              ((InvokePattern)objPattern).Invoke();
          }
  
  Code snippet for toolstrip:
  
      enter code here
      // toolStrip1
              // 
              this.toolStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
              this.toolStripButton1,
              this.toolStripComboBox1,
              this.toolStripButton2});
              this.toolStrip1.Location = new System.Drawing.Point(0, 0);
              this.toolStrip1.Name = "toolStrip1";
              this.toolStrip1.Text = "toolStrip1";
              // 
              // toolStripButton1
              // 
              this.toolStripButton1.Name = "toolStripButton1";
              this.toolStripButton1.Text = "toolStripButton1";
              // 
              // toolStripComboBox1
              // 
              this.toolStripComboBox1.Name = "toolStripComboBox1";
              this.toolStripComboBox1.Size = new System.Drawing.Size(121, 25);
              // 
              // toolStripButton2
              // 
              this.toolStripButton2.Name = "toolStripButton2";
              this.toolStripButton2.Text = "toolStripButton2";
              //
