Hi,

On the client side, a grid view is an html table.

In JavaScript, to get the number of rows on an html table, you would check the length of the tables row collection.

Access your GridView using its ClientID property, and you have a reference to your html table.

Something like this should work:

JavaScript

var gridViewRowCount=document.getElementByID('<%=gv.ClientID%>').rows.length;

... Hope it helps.

You need to create object of your link first and then add attributes to it. check below code -

C#

foreach (GridViewRow row in gv1.Rows)
 {
    //Creates object of button inside your gridView Row
    Button btnRowCommand = (Button)row.FindControl("YourButtonName");
    //Adds Attribute to buttonng="sql">button - in this case adds onclick attribute
    //which will fire the
    //gv1RowCommand(ID); javascript function
    btnRowCommand.Attributes.Add("onclick", "gv1RowCommand('"+ ID +"');");
 }

function gv1RowCommand(ID) {
alert('Row command test');
}
