Disable/hide a button from column Posts

How can I disable/hide a button from column by checking a particular condition. Following is my code..

  $("#jqxgrid").jqxGrid(
         {
             source: source,
             theme: theme,
			 width: 630,
			 height:1000,
                         autoheight: true,
			 autowidth: true,
		         sortable: true,
			 editable:true,
                         selectionmode: 'none',

         columns: [

		  { text: 'Entry Date', datafield: 'date', width: 200},
	          { text: 'Unit registration no.', datafield: 'receiptno', width: 200},
                  { text: 'Unit', datafield: 'unit', width:170,cellsalign: 'left' },
	          { text: '       ', columntype: 'button',value:'Print', datafield: 'Print', cellsrenderer: function () {
                     return "Reprint";

                 }}

           ]
         });

Hi basim.sherif,

It isn’t possible to disable or hide a button from a buttons columns. However, this should be possible by using a normal column with custom cellsrenderer implementation and the cellsrenderer returns a standard button. I suggest you to take a look at this sample: customcolumn.htm. The sample illustrates how to implement a cellsrenderer function which returns custom HTML which depends on the cell’s value.

Hi basim.sherif,

Here’s a sample which enables/disables buttons in a column using the cellsrenderer function. When a button is clicked, a function called buttonClick is invoked.
