Apply the color of the girdview mouse to all pages and select all the clients.

Write a common JS Function

Code

  Function  Gridviewcolor (gridviewid ){
  //  Obtain all rows to be controlled  
    VaR  Allrows  =  Document. getelementbyid (gridviewid );
  If (Allrows  ! =     Null  ){
Allrows  =  Allrows. getelementsbytagname (  "  Tr  "  );

  //  Set the background color and events of each row. The cycle starts from 1 instead of 0. You can avoid the row in the header.  
    For (  VaR  I  =     1  ; I  <  Allrows. length; I  ++  ){
Allrows [I]. onmouseout  =     Function  (){  This  . Style. Background =     "  # Ffffff  "  ;}
}
}
} 

To reference this JavaScript code, you only need to register it in page_load on each page. ctl00_pagebody_gvitems is the Client ID of girdview. 

  Scriptmanager. registerstartupscript (This. Page,This. GetType (),"JS","Gridviewcolor ('ctl00 _ pagebody_gvitems ');",True);
 

All selectedCode:

  <  Script  Type  = "Text/JavaScript"  >  
  Function  Checkall (ocheckbox)
{
  VaR  Gvitems  = Document. getelementbyid (  "  <% = Gvitems. clientid %>  "  );
  For  (I  =     1  ; I <  Gvitems. Rows. length; I  ++  )
{
Gvitems. Rows [I]. cells [  0  ]. Getelementsbytagname (  "  Input  "  )[ 0  ]. Checked  =  Ocheckbox. checked;
}
}
