refreshColumns

refreshes the structure of DataGrid

function refreshColumns(
    // an array with new configurations for the columns
    config?: array
): void

dgrid.refreshColumns();

When used without an argument, the method repaints the current grid structure.

Use it to refresh the structure of DataGrid after modifying some properties in its columns collection:

dgrid.config.columns[2].id = "newPrice";
dgrid.config.columns[2].width = 500;
dgrid.refreshColumns();

Or to change columns completely:

var config = [
  {id:"col1", header:"First Name", width:150},
    {id:"col2", header:"Last Name", width:150}
];

dgrid.refreshColumns(config);
