Object reference not set error message when i try to add Taginstance in Filter properties of a control

Problem:

I did a recording of the control then i open its filter properties and removed all information. then i open it search properties and try to add Taginstance in it search property and i got an Error "object reference not set to an instance on an object " and VS quits after this ?

Solution:

1. delete tag instance from filter properties
2. save it 
3. add tag instance in search properties (it will throw exception and Exit VS  that's fine
4. re-open that file and go to search properties and Add Tag instance now it will add without exception

parameterising a form with text and dropdown controls:

 Scenario:

I have a form that have 2 text boxes and one drop down with 6 values to select from, I have parameterise the text boxes to take values from a CSV file but how can i do this for a dropdown

 solution:

you can try the following way :

         //Method to select item
        public void SelectItem1(string Item)
        {
            #region Variable Declarations
            HtmlComboBox uIItemComboBox = this.UIDellTheOfficialSiteDWindow.UIDellTheOfficialSiteDDocument.UISelfrmCustom.UIItemComboBox;
            #endregion             // Select 'Japan' in 'Unknown Name' combo box
            uIItemComboBox.SelectedItem = Item;
        }

Calling this in your CodedUITest1.cs  like

             string Item = TestContext.DataRow["Item"].ToString();              this.UIMap.SelectItem1(Item);

This is a small example to select the dropdown item from the CSV file, You can tweak it as per your requirement.
