datagrid filter textboxes - set prompt

[gordis gmbh]

How can I set a default prompt to all the filter textboxes of all filter-enabled datagrids?

The prompt may be for e.g. 'enter filter text here...'

Just set the 'prompt' option for the textbox.

Code:

dg.datagrid('enableFilter', [{
    field:'attr1',
    type:'textbox',
    options:{
        prompt:'enter filter text here...'
    }
}]);

To enable filter as per your suggesstion one needs field name.

We enable filter for all datagrids in one central location as follows:

Code:

	if (specialFilters.length > 0) {
		$('#'+datagridSelector).datagrid('enableFilter', specialFilters);	 // enable filter with given special filters
	} else {
		$('#'+datagridSelector).datagrid('enableFilter');	// enable filter with type textbox
	}

As you can see, there is no datagrid-field information given for textbox-based filters. Special filters are combobox or datebox or numberbox filters which contain field-name and corresponding options...

For time being I found a workaround by adding the following line directly in source code file "datagrid-filter.js":

Code:

input.attr('placeHolder', 'enter filter text here ...');

This works but I am looking for a possibility to do the same - by default - for all filter-enabled datagrids without modifying the source code.

Perhaps by extending the filter - plugin in my code. But the problem is, setting the prompt after the textbox is initialised effects the textbox size! Any ideas in this direction are welcome ...

You can override the 'defaultFilterType' and 'defaultFilterOptions' to set properties for all un-specialed fields.

Code:

var dg = $('#dg').datagrid({
    defaultFilterType: 'textbox',
    defaultFilterOptions: $.extend({},$.fn.datagrid.defaults.defaultFilterOptions,{
        prompt:'enter filter text here...'
    })
});
