Ajax tooltip for only one column of a grid

[SrinivasKothuri]

Hi,

Is it possible to have an Ajax tooltip for only a single column of the ExtJS grid?

If yes, please provide some sample code.

Thank you.

Add a renderer to the target grid column, where the tooltip data is taken from a field in the current record:

renderer: function(value, metaData, record, rowIndex, colIndex, store) {
  metaData.tdAttr = 'data-qtip="' + record.get('someFieldName') + '"';
  return value;
}

Hi friend,
thank you for the reply.
But my requirement here is to contact server by an ajax call to get the Tooltip content.
