how to change DataGrid specific column alignment to Center in C# programmatically
-
Is this a WinForms datagrid (prolly not), an ASP.NET grid or a WPF-grid? In WinForms, life is simple;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
class Test
{
public string Item1 { get; set; }
public string Item2 { get; set; }
public string Item3 { get; set; }
}DataGridView grid; public Form1() { List data = new List(); data.Add(new Test() { Item1 = "bla", Item2 = "foos", Item3 = "bar" }); InitializeComponent(); grid = new DataGridView() { Dock = DockStyle.Fill }; grid.DataSource = data; Controls.Add(grid); MessageBox.Show(string.Format("There are {0} columns in this grid", grid.Columns.Count)); } protected override void OnShown(EventArgs e) { base.OnShown(e); grid.Columns\[0\].DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter; } }}

You're creating a UI element inside a Windows Service? Why? A service has no UI, so what are you trying to accomplish here?

We can use dataset and result is coming and displaying 4 columns. Only i need to do particular column alignment. But its not working.
You haven't answered my question. Why are you trying to do this inside a service? A service should have no user interface.

Ummm, you've got a HUGE problem. Windows Services cannot display a UI. Starting with Windows Vista, services that attempt to display a UI only show their interface on a separate desktop from the user that's logged in. The user gets a notification that a service has put up a UI window and asked if they want to switch desktops to see it. UI restrictions on services have now gotten to the point where a service cannot show a UI at all. This "transition" period comes from the days on Windows XP where a service could show a UI. This is a security risk so Microsoft has removed the ability to do this from Windows.

Hi i have created DataGrid and i need to align the specific column (4th column i.e index 3) to Center in C# programmatically. I tried as below dg1.Columns[3].ItemStyle.HorizontalAlign = HorizontalAlign.Center; but giving error as follows Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index even if i give index 0 also same error How to achieve this. If anybody knows reply me. Thanks in advance.

If you're just trying to write out to a file as HTML, then why are you trying to write it out this way? A simpler method would be to save your DataSet out as XML and use a page that XPath to read and display the content.

What does this have to do with writing a Windows Service application?

But through coding if i type DataGrid.Columns[] Columns property it will show. But after adding below code it is not working dg1.Columns[3].ItemStyle.HorizontalAlign = HorizontalAlign.Center; What to do. Please reply me.

Only if you're referencing a DataGridView, and that's a different control. Either you switch to the DataGridView, or you adjust the requirement of needing the alignment.
