I actually used the following statement
string str = new string('*', 10)
|
|
|
|
|
That doesn't meet the stated criteria.
|
|

|

I have the following code:
SqlConnection con = new SqlConnection("connection details");
con.Open();
string strSql = "select * from Names";
SqlDataAdapter dadapter = new SqlDataAdapter();
dadapter.SelectCommand = new SqlCommand(strSql, con);
DataSet dset = new DataSet();
dadapter.Fill(dset,"Names");
con.Close();
dataGridView1.DataSource = dset.Tables["Names"];
The dset looks as follows:
ID Name
1 Terence
2 Richard
1. How can I get my datagrid to only show the Name and not the ID column?
2. Also if I have a column named First Name in my datafrid how can I get name to show up in that column and not in a new one or how can I assign custom names to my datagrid?
Any help would be great thanks!

Thanks for the info  , I need the * as I need the ID for other things. I just dont want the ID to appear in the datagrid...

Using "*" is considered bad practice.
They only reason why you're seeing the ID in the datagrid is because you're relying on it's automatic features to create the columns for you.
If you created the columns and bound them yourself, you get to pick and chose which columns you see in the grid. You've already been given links to the docs and samples that show this.

Like this:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
AutoGenerateColumns="False" >
<Columns>
<asp:BoundField DataField="EmployeeID" HeaderText="EmployeeID" ReadOnly="True" SortExpression="EmployeeID" />
<asp:TemplateField HeaderText="EmployeeID" SortExpression="EmployeeID" Visible="false">
</asp:TemplateField>

Similar logic as above.

1. You could change your query to fetch only the name.

2. You could hide the first column inside the datagrid by using the visible property of the column.
dataGridView1.Columns(0).Visible = False

Not an option as I might need the id elsewhere

Worked perfectly by doing the following:
dataGridView1.Columns[0].Visible = false; instead of () needed to use [].
Thanks. Now just to name my Columns!

|
|
|

Solution:
dataGridView1.Columns[0].Visible = false;
dataGridView1.Columns[1].HeaderText = "First Name";
Is this the best way to do it? Any downsides?

If someone added another column, or insert a column before the firstcolumn, the datagridview will display wrongly. Generally I will define the columns to be displayed and their order, instead of hiding the columns that I do not want to display.
|
|

|

Define only the columns that you want to display in the datagridview:
this.dataGridView.AutoGenerateColumns = false;
this.dataGridView.Columns.Clear();
this.dataGridView.Columns.AddRange(GetGridViewColumns());
private DataGridViewColumn[] GetGridViewColumns()
{
DataGridViewTextBoxColumn id = new DataGridViewTextBoxColumn();
id .DataPropertyName = "ID";
id .HeaderText = "ID";
id .Name = "ID";
id .SortMode = DataGridViewColumnSortMode.Automatic;
id .ReadOnly = true;
id .Width = 100;
id .DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
id .DefaultCellStyle.Format = "";
DataGridViewTextBoxColumn name= new DataGridViewTextBoxColumn();
name.DataPropertyName = "Name";
name.HeaderText = "Name";
name.Name = "Name";
name.SortMode = DataGridViewColumnSortMode.Automatic;
name.ReadOnly = true;
name.Width = 100;
name.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleLeft;
name.DefaultCellStyle.Format = "";
return new DataGridViewColumn[] { id, name };
}

Thank you so much this is perfect. Just what I am looking for! Codeproject is such a great community!
|
|
|
|

try this after you set the DataSource:
dataGridView1.DataSource = dset.Tables["Names"];
dataGridView1.Columns["ID"].Visible = false;
Hope it could help you.

Hi...
I am getting NotSupportedException "The given path's format is not supported."
XmlDocumentObject.Save(filename);
filename is "L:PROT", because it contains colon that's why exception is coming.
Is there any alternative to use : in filename which could be saved in XmlDocument?
Thanks in Advance..

There are certain characters and filenames (such as CON or PRN) that you can't use when writing out a file. The : is used as a part of path identification, so is unavailable. You need to remove this colon.

hi,
System.IO.Path.InvalidPathChars will return a char array contianing the platform specfic characters that cannot be specified in path string.
-> compare your characters against the invalid chars to determinate that your path is valid or not..

Hi everyone;
I want to add some information on my print document.
To be precise
I'm printing my DataGridView like this:
private void button5_Click(object sender, EventArgs e)
{
if (SetupThePrinting())
MyPrintDocument.Print();
}
private bool SetupThePrinting()
{
PrintDialog MyPrintDialog = new PrintDialog();
MyPrintDialog.AllowCurrentPage = false;
MyPrintDialog.AllowPrintToFile = false;
MyPrintDialog.AllowSelection = false;
MyPrintDialog.AllowSomePages = false;
MyPrintDialog.PrintToFile = false;
MyPrintDialog.ShowHelp = false;
MyPrintDialog.ShowNetwork = false;
if (MyPrintDialog.ShowDialog() != DialogResult.OK)
return false;
MyPrintDocument.DocumentName = "Customers Report";
MyPrintDocument.PrinterSettings = MyPrintDialog.PrinterSettings;
MyPrintDocument.DefaultPageSettings = MyPrintDialog.PrinterSettings.DefaultPageSettings;
MyPrintDocument.DefaultPageSettings.Margins = new Margins(40, 40, 40, 40);
if (MessageBox.Show("Verilerin sayfaya ortalanmasını istiyor musunuz?", "Baskı Özellikleri - Sayfa Ortalama", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
MyDataGridViewPrinter = new DataGridViewPrinter(dbGridView, MyPrintDocument, true, true, "KASA DÖKÜMÜ\n\nbakiye:"+label17.Text+" gelir:"+label19.Text+" gider:"+label18.Text+"", new Font("Tahoma", 10, FontStyle.Bold, GraphicsUnit.Point), Color.Black, true);
else
MyDataGridViewPrinter = new DataGridViewPrinter(dbGridView, MyPrintDocument, false, true, "KASA DÖKÜMÜ\n\nbakiye:"+label17.Text+" gelir:"+label19.Text+" gider:"+label18.Text+"", new Font("Tahoma", 10, FontStyle.Bold, GraphicsUnit.Point), Color.Black, true);
return true;
}
So, I need to make two changes:
1. I need to add a line to the end of the document to put the information on my label#'s, how to put this line properly ( if possible such as: "The information is" +label7.text+ " format)
2. Because of the number of columns, my document prints 6 pages for a 3-paged information. also uses first 3 pages for first 4 columns, and the last 3 pages for the rest of the columns. Reducing the character size in the print document could be a solution, but I don't know how to do that either.
Can anybody PLEASE help  ?

Thank you but it seems like PrintPage event is more likely used for adjusting the margins or determining the printable boundaries; generally features about the document. I think I just need to decrease the font size of the text in the printed document. any idea?

no one ?

Help please
Does anyone know an elegant way to initiate a bash/perl script (to run on a linux box) from a windows form written in C#?
Thanks
