There is a not documented option recreateFilter - set it to true. The option should be set in navGrid (if used) where the search options are placed.

Tghis option recreates the filter every time and reread the colmodel options from the colmodel.

Eg : I have continents, Countries, States and Cities. I need to show USERS a filtered view when user chooses CONTINENT , I should display ONLY countries in the COUNTRY column  multiselect options and similarly it goes for states. I should not make server side call for each filter.  I am calling the following function from LOADCOMPLETE event of GRID but this is not working for the obvious reason mentioned in this thread.

 

function setSearchSelect(columnName)
{

$("#list").jqGrid('setColProp', columnName, {

editoptions: {
value: buildSearchSelect(getUniqueNames(columnName)),
multiple: true

},

searchoptions: {
sopt: ['eq', 'ne'],
value: buildSearchSelect(getUniqueNames(columnName)),
attr: { multiple: 'multiple', size: 4 },
dataInit: dataInitMultiselect

}
}
);
}

This is true, the setColProperty changes the property, but not already created content.

 $("#productpacks_list_grid").trigger("reloadGrid");

This successfully updates the drop down in the grid. But the drop down in the toolbar for that column is not updated. I looked through the wiki and didn't find anything that seemed to address this.
