Here is even more info.

If I comment the following two lines in the code below then the date column renders correctly but the date filter function does not. If I have the two lines uncommented then the date column does not render correctly but gets NaN-NaN-NaN but the date filter is correctly set.

schemaGenerated: generateSchema,
 columnsgenerated: generateColumns,

$("#dataGrid").igGrid({
 schemaGenerated: generateSchema,
 columnsgenerated: generateColumns,
 dataRendering: gridRendering,
 autoGenerateColumns: true,
 defaultColumnWidth: "150px",
 width: "100%",
 dataSource: data,
 dataSourceType: "json",
 responseDataKey: "data",
 features: gridFeatures
 });
function generateSchema(evt, ui) {
 var nrOfColumns = ui.schema.fields.count();
 for (var i = 0; i < nrOfColumns; i++) {
 var metadata = currentViewInfo.metaDataList[i];
 ui.schema.fields[i].type = metadata.ColumnDataType;
 }
}

function generateColumns(evt, ui) {
 var nrOfColumns = ui.owner.options.columns.count();
 for (var i = 0; i < nrOfColumns; i++) {
 var metadata = currentViewInfo.metaDataList[i];
 ui.owner.options.columns[i].dataType = metadata.ColumnDataType;
 }
} 

Hello Fredrik, F2O,

I want to share with you some good news.

We decided to implement a solution of this IE 8 behavior in our codebase for the next Ignite UI SR.

Hello Fredrik,

It took me a little time and now it works.

Thanks for your very useful help!

Best Regard.

Hi F2O,

We are using the igDatePicker. However we are using column templates and we loop each column and set its properties when we bind data to the grid. Something like this:

cols[i].key = metadata.ColumnKey;
cols[i].hidden = metadata.ColumnHidden;
cols[i].headerText = metadata.ColumnText;
cols[i].format = metadata.ColumnFormat;
cols[i].template = metadata.ColumnTemplate;

Where the format determines the date format for a date column and the template determines whether or not a color should be set for dates more than X etc.

Best Regards

Fredrik

Hello Fredrik,

Thank you for your reply. I think the 2nd option is better.

Do you use a igDatepicker or igDateEditor? 

Because I am using a rowEditTemplate, so a date must be able to be picked in a calendar... When it is formatted in String, how display it in a igDatePicker?

Best regards,

Hi F2O,

We chose to go with the second option because it is overall safer and if you allow different date formats your web frontend doesn't have to worry about them. Personally I do not like overriding or appending behavior to javascript prototypes. If your backend is C# then you should handle all your dates as datetime objects and it should hence not be that long of a stretch to format them as milliseconds since 1970-01-01 and then specify the format for how to display the date in the web layer. In order to get the grid to display your date all you have to do is give it the time in milliseconds and a format string. However some date formats seems to be invalid for some reason. For e.g. dd-MMM-yyyy.

Best regards

Fredrik
