In my grid, I have a number of columns marked as editable.

However, I need to make some of the rows being returned in the JSON to be readonly.

How can this be done?

Is there anything I can add to the JSON for those rows?

Can I iterate over the rows and set a flag to prevent editing on all the columns in that row?

Any other options?

Thanks,

Glen

Here's what I've tried...

function BeforeCellEdit(rowid, cellname, value, iRow, iCol) {

var grid = $('#results');

window.status = rowid + '-' + cellname + '-' + value + '-' + iRow + '-' + iCol; // confirm the values being received

var readOnly = grid.getCell(rowid, 1); // hidden cell containing True or False for a read-only row

      if (readOnly == 'True') {
        grid.restoreCell(iRow, iCol);
        return false;
        //TODO: this is not preventing edit
      }
    }

What else should be done?

The first thing you should try is changing (readOnly == 'True') to use true without qoutes.

Outside that how come you're not trying the method I linked?:

beforeEditCell: function (rowid,name,val,iRow,iCol){
if (rowid == 1){

jQuery("#jqg_"+id,"#results").attr('editable',false);}},

If your looking for cell level changes I suggest:

$("#results").removeClass('edit-cell').setCell(rowid,'columnname','','not-editable-cell');

Thanks Tim.

(I posted my entry immediately after yours, and didn't see yours...)

This is what I have now, and it is working:

function GridComplete() {
var grid = $('#results');
var rowids = grid.getDataIDs();
var columnModels = grid.getGridParam().colModel;

// check each visible row
for (var i = 0; i < rowids.length; i++) {
var rowid = rowids[i];
var data = grid.getRowData(rowid);

    if (data.AccessType == '0') {       // view only
      // check each column
      for (var j = 0; j < columnModels.length; j++) {
        var model = columnModels[j];
        if (model.editable) {
          grid.setCell(rowid, model.name, '', 'not-editable-cell', {editable: false});
        }
      }
    }
}
}
