Use the direction key to mark selected rows in the gridview

define JavaScript events in aspx to determine whether the buttons are up or down.

Function markrow (rowid)
{
If (document. getelementbyid (rowid) = NULL)
Return;

If (document. getelementbyid (currentrowid )! = NULL)
Document. getelementbyid (currentrowid). style. backgroundcolor = '# ffff ';

Currentrowid = rowid;
Document. getelementbyid (rowid). style. backgroundcolor = '# ff0000 ';
}
</SCRIPT>
Then, in the rowdatabound of the gridview, add the event processing function for processing keys and select the event when you click a row with the mouse.

Protected void gridview1_rowdatabound (Object sender, gridviewroweventargs E)
{
If (E. Row. rowtype = datacontrolrowtype. datarow)
{
E. Row. Attributes. Add ("ID", _ I. tostring ());
E. Row. Attributes. Add ("onkeydown", "selectrow ();");
E. Row. Attributes. Add ("onclick", "markrow (" + _ I. tostring () + ");");

_ I ++;
}
}
When a row is clicked, It is selected directly, and then the direction keys are moved to switch between different selected rows. If you press the direction keys directly, it is marked from the first row.
