  Guys,
  
  Until 2007.Q3 was possible to use the default CommandItem and hide the buttons just using the code:
  
  

  protected void grid_ItemDataBound(object sender, GridItemEventArgs e)

  {

  if (e.Item is GridCommandItem)

  {

  LinkButton addButton = e.Item.Controls[0].Controls[0].Controls[0].Controls[0].Controls[0] as LinkButton;

  addButton.Visible = false;

  }

  }

  
  With 2008.Q1 "Futures", the code cannot find the button.
  
  Some ideas?
  
  []'s!

  Hello Henrique,
  
  We introduced an easier method to get access to the buttons inside the default command item, namely by calling the FindControl(id) method (passing the id of the corresponding button). We think that this is more elegant approach than referencing items from the Controls collection of the command row elements (going several levels deeper).

  Hi Stephen!
  
  Thanks for your quick response!
  
  I tried the code:
  
  

  protected void grid_ItemDataBound(object sender, GridItemEventArgs e)

  {

  if (e.Item is GridCommandItem)

  {

  LinkButton addButton = e.Item.FindControl("InitInsertButton") as LinkButton;

  addButton.Visible = false;

  }

  }

  
  But addButton is null.
  
  Am I doing it right?

  Hello Henrique,
  
  Try the following code modification:
  
  

  protected void grid_ItemDataBound(object sender, GridItemEventArgs e)

  {

  if (e.Item is GridCommandItem)

  {

  ImageButton addButton = e.Item.FindControl("InitInsertButton") as ImageButton;

  addButton.Visible = false;

  }

  }

  Hi Stephen!
  
  Your code doesn't even compile.
  You're trying to pass a ImageButton to a LinkButton, but is not the case.
  The method FindControl returns NULL.
  Insert a breakpoint and you'll see.
  
  e.Item.FindControl("InitInsertButton") == null !!!
  
  Thanks again for your quick response.

  PS: I've requested a feature and now I'm just posting it in a public forum:
  
  Add two attributes for tag "CommandItemSettings":
  

  • AddNewVisible
  • RefreshVisible

  I don't want to change the Command style or create a new template. I want to use yours template but sometimes, don't want to use one of the buttons.
  Would be nice if we have these two attributes! (less code for us)
  
  Thanks again!

  Hello Henrique,
  
  I apologize for the mistake I made in my previous post. Actually you need to cast the [Add new record] button to Button instead of ImageButton, namely:
  
  

  protected void grid_ItemCreated(object sender, GridItemEventArgs e)

  {

  if (e.Item is GridCommandItem)

  {

  Button addButton = e.Item.FindControl("InitInsertButton") as Button;

  addButton.Visible = false;

  }

  }

  
  This is due to the new rendering of the default grid images (rendered with img tags) which are now part of sprites. We plan to add a separate topic in the grid online documentation elaborating on this matter for the official Q1 2008 release, scheduled in the middle of April.

  Just one more thing.
  The text set on attributes are not appearing.

  Hi Henrique,
  
  The text for the [Add new record]/[Refresh] buttons in the command item will appear as tooltip when you hover the relevant button. Do you consider this change appropriate or prefer to have the previous text message side by side with the button? We may consider reverting back the old behavior (having text beside the button) for the official Q1 2008 release.

  Stephen,
  
  I don't know how users are there, but here in Brazil ... some of them are so dumb that sometimes we need the text.
  Just a suggestion, you can leave the old behavior and if we don't want the text, just set the attribute "AddNewRecordText" or "RefreshText" to empty (""). Another consideration, is to add two attributes "AddNewRecordToolTip" and "RefreshToolTip" like the validators have: a text for a tooltip, a text for span and another one for javascript.
  
  OK!?
  
  I know that is a "big" change, but I'm helping you to keep your job!!

  Hi Henrique,
  
  I spoke with our grid developers and they stated that the old behavior (text beside the command item buttons) will be reverted for the Q1 2008 of RadControls Prometheus. I believe this is good news for you. Thank you for sharing your opinion on this subject.

  Stephen,
  
  Just more one question, I swear!
  Will you keep this code working on next version?
  
  

  Button addButton = e.Item.FindControl("InitInsertButton") as Button;

  
  Thanks again!

  Hi Christian,
  
  As of Q1 2008 the "Add New" button in the command item consists of two buttons. This is skinning optimization purposes.
  
  In order to hide both buttons (image and link), please use:
  
  

  protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

  {

  if (e.Item is GridCommandItem)

  {

  Button spriteAddButton = e.Item.FindControl("AddNewRecordButton") as Button;

  spriteAddButton.Visible = false;

  LinkButton addButton = e.Item.FindControl("InitInsertButton") as LinkButton;

  addButton.Visible = false;

  }

  }

  How do you hook this up in the ASPX page?

  Never mind, I found it, the "OnItemCreated" even for the RadGrid control, like so:
  
  <telerik:RadGrid ID="RadGrid1" runat="server" OnItemCreated="grid_ItemCreated">

  Hi,
  I'm using Q2- 2009. How do i add a tooltip to the "Refresh" button in the grid..
  

   

   

   

   

   

  if (e.Item is GridCommandItem)

  {

  ((LinkButton)e.Item.FindControl("InitInsertButton")).ToolTip = "Click here to add new record";

  }

   
  this worked for the "Add new record" button.  Please help me in providing a tooltip for the "Refresh" button.
  
  Thanks.

  Hello dinesh,
  
  The id of the default refresh button in the command item is RebindGridButton as explained in this topic. Hence using this code inside the ItemCreated server handler of the grid should do the trick:
  
  

  if (e.Item is GridCommandItem)

  {

  ((LinkButton)e.Item.FindControl("RebindGridButton")).ToolTip = "Click here to refresh the grid";

  }

  This seem to work for me:

  protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

  {

  //Hides the Add New Record option in the header

  if (e.Item is GridCommandItem)

  {

  e.Item.FindControl("AddNewRecordButton").Visible = false;

  e.Item.FindControl("InitInsertButton").Visible = false;

  }

  }

   

  I wired this up with OnItemCreated="RadGrid1_ItemCreated" in the RadGrid object.

  EDIT: Figured it out!  Updated below in bold.

  
  

  Ok, I have the following

  
  

  protected void PhoneBook_ItemCreated(object sender, GridItemEventArgs e)

  {

  //Hides the Add New Record / Refresh option in the header

  if (e.Item is GridCommandItem)

  {

  e.Item.FindControl("AddNewRecordButton").Visible = false;

  e.Item.FindControl("InitInsertButton").Visible = false;

  e.Item.FindControl("RebindGridButton").Visible = false;

  }

  }

  
  

  This hides the Add New Record Button / Text and the Refresh text.  So, I've deduced...

  
  

  AddNewRecordButton = Green "+" button to Add New Record

  InitInsertButton = "Add New Record" text

  RebindGridButton = "Refresh" text

  RefreshButton = Refresh Button

  
  

  What is the control name for the refresh button so I can hide that as well?  I have referenced this topic, but it doesn't tell me what the Control ID is for the refresh button.
  

  
  

  Cheers,

  -Matt

  Hi Matt,
  The button which you trying to hide is not a image button it's just a button only, so try to write in this way.
  

  Button

   

   btn = e.Item.FindControl("RefreshButton") as Button;
  btn.Visible = false;

  Instead of finding all the controls and hiding them, just say
  
  

  protected void PhoneBook_ItemCreated(object sender, GridItemEventArgs e)

          {

              //Hides the Add New Record / Refresh option in the header  

              if (e.Item is GridCommandItem)

              {

                    e.item.visible = false;

              }

         }

  
  This should do the job.
