CS Code
Copy Code code as follows:
protected void Publicgridrowdeleting (object sender, Gridviewdeleteeventargs e)
{
String Strid = Gridlog.datakeys[e.rowindex]. Value.tostring ()//strid is the ID of the line
String strSQL = "Delete from table" +
"WHERE id =" + strid;
Perform deletes
Clientscript.registerstartupscript (GetType (), "message", "<script
language= ' JavaScript ' >alert (' delete successful! '); </script> ");
Gridbind ();
}
The key is to set a good datakeynames, you can rely on string Strid = Gridlog.datakeys
[E.rowindex]. Value.tostring (); Get the ID value of the selected column and then use this ID to perform the deletion.
