and want row value clicking image button, here's code :

 protected sub imgbtn_click(byval sender object, byval e imageclickeventargs)         dim btndetails imagebutton = trycast(sender, imagebutton)         dim gvrow gridviewrow = directcast(btndetails.namingcontainer, gridviewrow)         lblid.text = gvdata.datakeys(gvrow.rowindex).value.tostring()         lblusername.text = gvrow.cells(1).text         txtfname.text = gvrow.cells(2).text         txtlname.text = gvrow.cells(3).text         txtcity.text = gvrow.cells(4).text         txtdesg.text = gvrow.cells(5).text         me.pnlgrid_modalpopupextender.show()     end sub

but when debug it, gvdata.datakeys(gvrow.rowindex).value.tostring() value, others value give me empty string. whats wrong code??

you can use findcontrol method find control defined in template.

ie.

dim lblnoaccount0 label = directcast(gvrow.findcontrol("lblnoaccount0"), label)

then can value of label expected.

lblusername.text = lblnoaccount0.text
