1) In old days, we used to use CSS expression to make the fixed column header. but the CSS expression doesn't work in the non-IE browsers so we stop using this trick.. However, if your website is for IE users then you can still use the CSS expression which is really easy to use.
2) You can use the pure CSS to get the fixed column header.. For example : Pure CSS Scrollable Table with Fixed Header[^] but as you want to use this in Gridview, there is one problem that we can't set the CSS class to tbody of GridView. So, I used the CSS friendly adapter[^] to customize the gridview (without creating new gridview that inherit from standard gridview)
You can check my example here[^].
3) If you don't like this example, you can find another example with ASP.NET ajax. (or something.) I'm sure that there is an example with ASP.NET because i saw once in my feed reader.. I will find this example if i'm free and will let u know..
for the time being, you can test my example..

{
return num;
}
}
}
class B
{
int n = //How to take value of Class A in this variable.
public void put()
{
Console.WriteLine(n);
}
}
static void Main(string[] args)
{
B e = new B();
e.put();
Console.ReadLine();

I've done as given above but it's also throwing error
A field initializer cannot reference the nonstatic field, method, or property 'B.e'

You should have an constructor in Class A.
|
|
|
|
|
<br />
class A<br />
{<br />
private int num = 10;
public A()<br />
{<br />
}<br />
public int Pro<br />
{<br />
get<br />
{<br />
return num;<br />
}<br />
}<br />
<br />
}<br />
<br />
<br />
class B<br />
{<br />
<br />
A objA = new A();<br />
int n = new int ();<br />
public B()<br />
{<br />
n = objA.Pro;<br />
}<br />
public void put()<br />
{<br />
}<br />
}<br />

Not necessary. The problem is you are trying to assign the property value inside the class, not inside any methods. This is not allowed.

Are you saying that Class A doesn't need to have the constructor? assigning the value is the second pro..

Yes.

If there is no constructor then we can't create the object of class A. A objA = new A();. I know there are a lot of ways to do.. but based on my example 1, I did create the object of A. but i missed to mention to have the constructor in class A and B.

This is not correct. You can have a class without constructor. It is optional. Try creating a class without any constructor ? It won't show any problem. I guess internally default constructor would be created automatically. If we don't want to do any initialization stuff, we can avoid writing constructor.

Hi Navaneeth,
Yeah. You are correct. This is the second time that I made the mistake.  Sorry about that.. I didn't know that the default constructor is not a must. I always used to add the default constructor.. Thanks for correcting me..

 in the constructor of b declare the object of a and assign the value
print()
{
A aob= new A();
n = aob.Property;
}

This can be done in many ways
1st method
class A
{
protected int num = 10;
public int Pro
{
get
{
return num;
}
}
}
class B : A
{
int n = num;
public void put()
{
Console.WriteLine(n);
}
}
class Program
{
static void Main(string[] args)
{
B e = new B();
e.put();
Console.ReadLine();
}
}
2nd method
class A
{
private int num = 10;
public int Pro
{
get
{
return num;
}
}
}
class B
{
int n = 0;
public void put()
{
A a = new A();
n = a.Pro;
Console.WriteLine(n);
}
}
class Program
{
static void Main(string[] args)
{
B e = new B();
e.put();
Console.ReadLine();
}
}
Hope this helps

i created Microsoft Accessse database and i want to connect to it using oledb object how i can do this and the want to populate that grid from the data recived from datbase plz help me
wasim khan

Can you please try to google first? For example, if you want to know about how to connect the Microsoft Access database then you can type like "asp.net connect microsoft access" or similar one. The google will give a lot of results. You can read one by one. and you will get the idea about how to connect the database in ASP.NET.. then, if you got the specific problem, come back here and ask again..

I had created a single bound column in gridview and i have a typeddatset with column eid and ename.
dataset is filled on page_load.
I want to bind only ename column of dataset to that bound column o grid. how to do that??
thanks in advance
Gaurav

Hi,
You just need to set the AutoGenerateColumns property of GridView to False. Then the GridView will display only the Bound Columns added to it.
