how to froze rows as footer

[Part13anParticipant]

Hello,

I need to put a few rows from a grid datasourse in footer and froze them there. Is it possible? Is is hard to implement with aggreagtes. Or maybe you can show me some example how to froze 1 of rows in bottom of grid.

Thanks

Hello Part13an,

Unfortunately, we do not have such properly, but you could create a workaround.
For example could set showstatusbar: true and create in this content new Grid with same settings but with just one row.
Please, take a look at this demo for reference and to integrate new Grid instead of the buttons.
I hope this help.

Hi Part13an,

I have had a similar problem and have solved it with the following code. It determines min Date in a column and writes it as “aggregate” into the status line with “aggregatesrenderer”:

						aggregates:
							[
								{
									'mindate':		function (aggregatedValue, currentValue)
										{
											if (aggregatedValue == 0) {
												aggregatedValue = currentValue;
											} else {

												if (dates.compare(currentValue, aggregatedValue) == -1) {
													aggregatedValue = currentValue;
												}
											}
											return new Date(aggregatedValue);
										}
								}
							],
						aggregatesrenderer: function (aggregates)
							{
								var renderstring = "";
								$.each(aggregates, function (key, value) {
									renderstring += '<div style="position: relative; margin: 4px; overflow: hidden;">' + dateFormat(parseInt(value.replace(/\./g, "")), "dd.mm.yyyy") + '</div>';
								});
								return renderstring;
							},

greetings

Hello,

Thank you for answers, but I met strange error.

I have column with dataType = ‘date’ and cellsformat = “MMM-yyyy”. If I use custom aggregate which return any value (new Date(), ”, 0) I receive error:
jqx-all.js:7 Uncaught Bad number format specifier: M
formatnumber @jqx-all.js:7
(anonymous function) @jqx-all.js:7
each @jquery.js:657
getAggregatedData @jqx-all.js:7

_updateaggregates @jqx-all.js:7
_render @jqx-all.js:7
render @jqx-all.js:7
(anonymous function) @jqx-all.js:7

What value format should I Return? Other columns with different formats work fine, but these kind of columns just destroy all functionality.

Hello,
I have the same problem, as soon as I have used the columns format in columns. When I use a value other than “d” in columnsformat I get the same error when using aggregates. Therefore, I have created a localizationObject with the following function, this also works with your format:

/* #################################################################################################

var jf_getLocalizationDE = function () {
	var localizationobj = {};
	localizationobj.pagergotopagestring = "Gehe zu:";
	localizationobj.pagershowrowsstring = "Zeige Zeile:";
	localizationobj.pagerrangestring = " von ";
	localizationobj.pagernextbuttonstring = "voriger";

		D: "dddd, d. MMMM yyyy",
		t: "HH:mm",
		T: "HH:mm:ss",
		f: "dddd, d. MMMM yyyy HH:mm",
		F: "dddd, d. MMMM yyyy HH:mm:ss",

	}
	localizationobj.patterns = patterns;
	localizationobj.months = months;
	localizationobj.todaystring = "Heute";
	localizationobj.clearstring = "Löschen";
	return localizationobj;
}

The string for your aggregate should be:

renderstring += '<div id="AggDatum_von" style="position: relative; margin: 4px; overflow: hidden;">' + dateFormat(parseInt(value.replace(/\./g, "")), "mmm-yyyy") + '</div>';

My column is defined as:

					{
						text:			'Datum von',
						datafield:		'Datum_von',
						// use only this cellsformat !!! otherwise Error!
						cellsformat:		'd',
						cellsalign:		'right',
						width:			100,
						aggregates:
							[
								{
									'mindate':		function (aggregatedValue, currentValue)
										{
											if (aggregatedValue == 0) {
												aggregatedValue = currentValue;
											} else {
												if (dates.compare(currentValue, aggregatedValue) == -1) {
													aggregatedValue = currentValue;
												}
											}
											return new Date(aggregatedValue);
										}
								}
							],
						aggregatesrenderer: function (aggregates)
							{
								var renderstring = "";
								$.each(aggregates, function (key, value) {
									//renderstring += '<div id="AggDatum_von" style="position: relative; margin: 4px; overflow: hidden;">' + dateFormat(parseInt(value.replace(/\./g, "")), "dd.mm.yyyy") + '</div>';
									// your renderstring:
									renderstring += '<div id="AggDatum_von" style="position: relative; margin: 4px; overflow: hidden;">' + dateFormat(parseInt(value.replace(/\./g, "")), "mmm-yyyy") + '</div>';
								});
								return renderstring;
							},
					},

My js function for dates are:

The localizationObject should be defined in jqxGrid as:

				localization:		jf_getLocalizationDE(),

I hope this helps you further …

Have a nice weekend…
