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.

That means that your columns have not yet been created at that point.

Change the alignment AFTER binding - the datageridview does not have the columns at the point where you are accessing them. If it did, the index would not be out of range.

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<Test> data = new List<Test>();
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.

Ya but i have created one html file and for that i am sending this dataset after rendering as
StringWriter stringWriter1 = new StringWriter();
HtmlTextWriter htmlWrite1 = new HtmlTextWriter(stringWriter1);
i am trying read html file and after reading just rendering the control as shown below
dg1.RenderControl(htmlWrite1);
i am getting html file result and that 4 column grid.
Only i need to make particular column alignment.
How to do this.

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.

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.

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

Next to the "no UI" issue, there's also the point the a DataGrid[^] doesn't have a columns-property.
Yes, it is faster in displaying data than a DataGridView, but it doesn't have as much features built in.

dg1.Columns[3].ItemStyle.HorizontalAlign = HorizontalAlign.Center;

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.

I have a string array which will be different but I always need to create a CreateTextTableCell based on AppSettings("RosterFields") fileds count. If no string is found in ArrayHeader create an empty cell up to Settings("RosterFields"). My code below is not working what I have missed?
Dim ArrayHeader() As String = {"1","2"}
For columnIndex = 0 To ConfigurationManager.AppSettings("RosterFields") - 1
For Each value As String In ArrayHeader
CreateTextTableCell(Row, columnIndex, value.ToString, currentRow, 182, True)
Next
Next

I need to retrieve the .NET 4.0 install path from a batch file. Following is my batch file code snippet:
REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP" /s|FIND "InstallPath"|FIND "4.0."||ECHO
The result is
InstallPath REG_SZ C:\Windows\Microsoft.NET\Framework64\v4.0.30319\
However, I need to assign the path to a variable. I found some related post online but can’t get any of them work. Any advice is greatly appreciated!
Cheers!

Why are you using a .bat file? You can extract this information direct from the registry via the RegistryKey Class[^].

I know using C# I can do almost anything. However, QA have been using batch files for long time. They know nothing about .NET programming. I am helping to add new features to the batch file, not making technical change at this point. Thanks!

|

Then your statement "However, I need to assign the path to a variable.", needs more detail about what this has to do with the .NET framework.
