TableBean.java

public class TableBean {

private perInfo[] perInfoAll = new perInfo[]{

new perInfo(105, "SYMONDS", "9313999999", "eee", 55555),
};

public perInfo[] getperInfoAll() {
return perInfoAll;
}

public class perInfo {
int id;
String name;
String phone;
String city;
int pin;

public perInfo(int id, String name, String phone, String city, int pin) {
this.id = id;
this.name = name;
this.phone = phone;
this.city = city;
this.pin= pin;
}

public int getid() {
return id;
}

public String getname() {
return name;
}

public String getphone() {
return phone;
}

public String getcity() {
return city;
}

public int getpin() {
return pin;
}

}

Core JSF doesn't support scrolling. However many third-party add-ons do. Check out MyFaces Tomahawk or JBoss RichFaces, for example.

I surrounded my dataTable with:

<div style="overflow:auto; width=700px; height=400px;">
<h:dataTable>
.
.
.
</h:dataTable>
</div>

I thought you meant record scrolling for large output data sets! Didn't realize you were looking to scroll the table rows themselves up and down.

Christoph ,
First of all thanks for the idea. If i use the <DIV> tag, the entire page is getting scrolled. I need the table alone to be scrolled dynamically. For example, scroll bar should be there only if the table exceeds 5 rows. I guess this can be done by javascript. Also do we have Height property for the Datatable.?

Please advice on this.

Use:

<div style="overflow: auto; border: 1px solid #ccc; height: 260px">

just around your <rich:dataTable> tag. This would do jsut what you want.

P.S. Replace the height parameter with the desired height of your data table.
