in this, edit functionality not working.

in clicking of edit button, shows me nothing. (it should show me textbox edit)

following code:

protected sub grdcontent_rowediting(byval sender object, byval e system.web.ui.webcontrols.gridviewediteventargs)      dim row gridviewrow = directcast(trycast(sender, control).parent.parent, gridviewrow)     dim index integer = row.rowindex      ctype(row.findcontrol("grdcontent"), gridview).editindex = e.neweditindex     dbname = ctype(row.findcontrol("lblname"), label).text     bindcontentgrid(ctype(row.findcontrol("grdcontent"), gridview), dbname) end sub

please me, not gives me error, not showing me textbox edit.

the issue on following code

bindcontentgrid(ctype(row.findcontrol("grdcontent"), gridview), dbname)

if code not return records, nothing displayed. make sure returning rows.
