Hi Memo

You can use the client-side-event OnRowContextMenu.

  function grdPL_OnRowContextMenu(controlId, rowType, rowElement, menuObject)
  {
      var i;
      for (i = 0; i < menuObject.Items.length; i  ) {
          if (menuObject.Items[i] != null) {
              if (menuObject.Items[i].Name == "mnuHelp") {
                  menuObject.Items[i - 1].Hide();
                  menuObject.Items[i].Hide();
              }
          }
      }
   return true;
  }

Hope it helps.

How can I remove (or dont show) grid filter options like "Is Not Empty" or 'Is Null' etc. Detail is in attached file.

You will need to add and customize your own filter Context Menu. E,g OnAfterInitialize event you can place the code like below:

function WebGrid1_OnAfterInitialize(controlId)
{
	var WebGrid1 = ISGetObject(controlId); 
	wg_Global.FilterType = new Array(["NotSet",0], ["GTET",1],["GT", 2],["ET", 3],["NET", 9] ,["LTET", 4] ,["LT", 5] ,["Like", 6] ,["NotLike", 11] ,["Between", 7] ,["NotBetween", 10] ,["IsEmpty", 14],["NotIsEmpty", 15]);
			
	return true;
}

For more information, please refer into our WebGrid references (documentation) and search for "How-to : Customize Filter context menu". It will sure give your information about the available Filter Context Menu. Hope this helps.

Hi Memo

You can use the client-side-event OnRowContextMenu.

You just need to find out how the menu is called.

Here is an example to hide the Help menu:

 

 

  function grdPL_OnRowContextMenu(controlId, rowType, rowElement, menuObject)
  {
      var i;
      for (i = 0; i < menuObject.Items.length; i  ) {
          if (menuObject.Items[i] != null) {
              if (menuObject.Items[i].Name == "mnuHelp") {
                  menuObject.Items[i - 1].Hide();
                  menuObject.Items[i].Hide();
              }
          }
      }
   return true;
  }

Thanks for your participation. Your solution will work for WebGrid row context menu, meanwhile what Memo needs is to modify WebGrid filter context menu. So I think Handy's response is the answer for Memo's scenario.

But it's okay your codes should be worked for another customer who needs to modify row context menu. 

By the way I have another tips for you: you can use GetNamedItem() method instead use For to loop all the menu items. Here the code snippet :

function WebGrid1_OnRowContextMenu(controlId, rowType, rowElement, menuObject)
{
	var grid = ISGetObject(controlId);
	var loadMoreItem = menuObject.Items.GetNamedItem("mnuLoadMore");
	loadMoreItem.Hide();         
	return true;
}

Thanks Michael,

But I dont want to remove or hide context menu items.

I want to hide some FilterTypes in Filter Menu that opened after clicking Filter Icon.

I attached it is screenshot.

Memo,

My replied above should be guided you how to do it. Please let me know if It doesn't work for your scenario.

Hi Dicky

Thank you for tip!

Hi Michael,

Unfortunately, sometimes I also used debugger (watch window) to know list of all menu items name. 
If I am not mistaken, the list of all menu items name is not located in our documentation yet.
So, I think we can talk to our documentation team for adding this into our docs.
Hope with this information could be helpful for another customer in the future.

Regards,
Handy
