title: jqGrid: change background color of row based on row cell value by column name
body: <p>jqGrid has column named Posted. It can be positioned in different positions depending how grid is configured by customer but is always prssent.</p>
  
  <p>I need to change background color of rows if Posted column has value True</p>
  
  <p>I tried colmodel below but alert(rdata.Posted) displays always undefined.</p>
  
  <p>How to change backgound color of row if Posted column in this row has value true ?</p>
  
  <p>I looked into lot of Oleg and other solutions for changing background color but they are using hard coded column number.</p>
  
  <pre><code>colModel: [
  
  {"cellattr":function(rowId, tv, rawObject, cm, rdata) {  
  if (rdata.Posted)
      return 'class="jqgrid-readonlycolumn"';
      return '';
        }
    ,"label":"Klient","name":"Klient_nimi","classes":null,"hidden":false},
  
  
  {"label":null,"name":"Posted","editable":true,"width":0,
  "classes":null,"hidden":true}],
  ...

  <p><strong>Update</strong></p>
  
  <p>In update2 Oleg recommends to use rowattr. I need to hide inlined delete button and custom post button in  actions column also. I'm usijng code below in loadComplete. How to implement this using rowattr ?</p>
  
  <pre><code>var LoadCompleteHandler = function () {
      var iCol = getColumnIndexByName($grid, 'Kinnitatud'),
        postedDateCol = getColumnIndexByName($grid, 'Kinkuup'),
        cRows = $grid[0].rows.length,
        iRow,
        row,
        className,
        isPosted,
        mycell,
        mycelldata,
        i, count,
        cm = $grid.jqGrid('getGridParam', 'colModel'),
        l,
        iActionsCol = getColumnIndexByName($grid, '_actions');
      l = cm.length;
      if (iCol &gt; 0 || postedDateCol &gt; 0) {
          for (iRow = 0; iRow &lt; cRows; iRow = iRow + 1) {
              row = $grid[0].rows[iRow];
              className = row.className;
              isPosted = false;
              if ($.inArray('jqgrow', className.split(' ')) &gt; 0) { // $(row).hasClass('jqgrow')
                  if (iCol &gt; 0) {
                      isPosted = $(row.cells[iCol]).find("&gt;div&gt;input:checked").length &gt; 0;
                  }
                  if (postedDateCol &gt; 0) {
                      mycell = row.cells[postedDateCol];
                      mycelldata = mycell.textContent || mycell.innerText;
                      isPosted = mycelldata.replace(/^\s+/g, "").replace(/\s+$/g, "") !== "";
                  }
  
                  if (isPosted) {
                      if ($.inArray('jqgrid-postedrow', className.split(' ')) === -1) {
                          row.className = className + ' jqgrid-postedrow';
                          $(row.cells[iActionsCol]).find("&gt;div&gt;div.ui-inline-del").hide();
                          $(row.cells[iActionsCol]).find("&gt;div&gt;div.ui-inline-post").hide();
                      }
                  }
              }
