Programmatically Hiding ASP.NET Grid View Column.

Recently I have been to and found that lots of people are finding solution for hiding the Grid View column so I though it will be a good Idea to write a blog post. In this post I will explain how we can hide GridView Column programmatically. So let’s take same example that I have taken in previous post.

Hide ASP.NET GridView Column:

So let’s take  a simple example. I am going to bind a grid with list of Employee class and then on a button click I am going to hide the first column of grid. Following is a HTML code for that.
    <asp:Button runat="server" Text="Hide Column" ID="btnHideColumn" OnClick="btnHideColumn_Click"/>
        <asp:GridView runat="server" ID="employeeGrid" AutoGenerateColumns="False">
                <asp:BoundField HeaderText="Employee Id" DataField="EmployeeId"/>
                <asp:BoundField HeaderText="First Name" DataField="FirstName"/>
                <asp:BoundField HeaderText="Last Name" DataField="LastName"/>

In the above code I have taken a grid view and I have taken a button to hide the Employee Id column. Here I have taken Employee class like following.
public class Employee
    public int EmployeeId { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }

Following is a code for binding GridView.
protected void Page_Load(object sender, EventArgs e)
    if (!Page.IsPostBack)
public void BindGridView()
    var employees = new List<Employee>()
            new Employee {EmployeeId = 1, FirstName = "Jalpesh", LastName = "Vadgama"},
            new Employee {EmployeeId = 2, FirstName = "Vishal", LastName  ="Vadgama"},
            new Employee {EmployeeId = 3, FirstName = "Teerth", LastName = "Vadgama"}
    employeeGrid.DataSource = employees;

As you can see in the above code I have created a method to bind GridView and called that method in page_load event.  In BindGridView method I have created a list of employee class and then bind that list to GridView. On the click of btnHideColumn I have written code to hide column like following.
protected void btnHideColumn_Click(object sender, EventArgs e)
    employeeGrid.Columns[0].Visible = false;

That’s it. Let’s run the example.

Now once you click Hide Column It will look like following.

That’s it. Its very easy. Hope you like it. Stay tuned for more..
