How to change GridView column alignments for dynamic data source ?

By default ASP.NET GridView Columns has left alignment text. We can use GridView ItemStyle property with either of GridView BondField or Template Field to change the default alignments.GridView properties,ItemStyle-HorizontalAlign having few set of values, using  which we can change the alignments.

Above customization is true when you are using Bound Field or Template Field for binding the data . But If you want to customize the same set alignments for data source which are directly binding with GridView you have to use Gridview_RowDataBound or Gridview_PreRender methods .

Let’s say you are binding below set of records directly with gridview

List<Employee> employees = new List<Employee>
{
new Employee{ID=1, Name="Employee 1", Address="Address 1" },
new Employee{ID=2, Name="Employee 2", Address="Address 2" },
new Employee{ID=3, Name="Employee 3", Address="Address 3" },
new Employee{ID=4, Name="Employee 4", Address="Address 4" },
new Employee{ID=5, Name="Employee 5", Address="Address 5" },
new Employee{ID=6, Name="Employee 6", Address="Address 6" }
};
GridView1.DataSource = employees;
GridView1.DataBind();

As the above set of records binded without any data bound field, you have to override the RowDataBound Event to set the alignment.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Cells[0].HorizontalAlign = HorizontalAlign.Right

}
}

DataControlRowType enum having the similar values as ItemStyle-Horizontal alignment.

Similarly you can override the same thing in GridView_PreRender Method as well

protected void GridView1_PreRender(object sender, EventArgs e)
{
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
row.Cells[0].HorizontalAlign = HorizontalAlign.Left;
}
}
}
