In asp.net When you bind data to datagrid it automatically assigns the header text of columns with the binding source fields. lets say my first field name is firstName and it displays as it is in the datagrid's column header text.But i want "First Name" instead of firstName.How could i achieve that without introducing some new table or with doing extra work.Keep in mind i dun wanna disturp the order of the colums????

Go to datagrids property bulider page and set the column header there

well but doing so disturbs the order of binding source columns...lets say i have 3 fields id firstName n lastName and my colum names "ID", "First Name" n "Last Name". After binding it assigns field without any order against ID it binds fiestName field so on n so forth.

this.Close();
either this or I don't get your question.
also you can manualy override
protected override void OnClosing(CancelEventArgs e)
{}
method if needed (like if you want user to confirm closing or fire up another method).

There is some code that opens a window which don't close on parents form close event. Also there is delegate, you could do without it ofc.
public partial class Form4Skaitymas : Form
{
Form4Skaitymas_DataSheet form4ska_dat = new Form4Skaitymas_DataSheet();
public delegate void PassData(string uzs_mod, int uzs_nr, string darbID);
private void Some_method_of_yours()
{
PassData PD = new PassData(form4ska_dat.showData);
PD(mod_nr, part_nr, textBox3.Text);
form4ska_dat.Show();
}
}
// note: I removed most of the code form it and left only the imortant parts, as an example.

Hi,
when reading a number in a TextBox with VB.NET i use:
Number = Val(TextBox1.Text).
How can this be done in C#
Thanks for any answer

|
|
|
|
int myNumber = int.Parse(TextBox1.Text);
or
double myNumber = double.Parse(TextBox1.Text);
Just choose the right data type (int, float, double, ...). Then using method Parse.

How about :
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"C:\Test.Xml");
|
|
|
|
|
That is not faster at all.

Well the super-fast method would be read them same way as plain text. Maybe XML is not good format for your application? If you want to, provide more details about that XML file and app...
