Hello Ian,

Thank you for contacting Infragistics!

Concerning the error you are getting it seems like the version in your toolbox is different than the version you have referenced in your project, like you updated to a later service release. You should be able to resolve this by updating your project references to reference the newer dll or change the references to be specific version false.

Hello Bruno,

Thank you for contacting Infragistics!

The behavior of an empty/blank cell being displayed when the value is cleared out is the default behavior. To have the null text be “Null” you can set the “UltraGrid.DisplayLayout.Override.NullText” to “NULL”. As for setting null when the user enters “NULL” I would recommend handling the AfterExitEditMode or BeforeExitEditMode event of the grid and if the text is “NULL” set the value to null.

Hello,

Thank you for the update. Yes that is correct the volumes build off each other and contain all the features from the previous release, plus any new features and bug fixes. You can think of the volume number as a version number.

Also from the release of each volume we do a year of service releases that contain bug fixes but no new features. When you combine the volume release number and service release number you get the full version number. For example the current service release for v17.1 is 2043, so the full version number is 17.1.20171.2043.

Hello,

Thank you for contacting Infragistics!

I am attaching a sample that demonstrates this behavior of setting a different format for each cell.

Hello Michel,

To achieve this you would set the format on the column:

http://www.igniteui.com/help/api/2016.2/ui.iggrid#options:columns.format

for example if you want a date and time to display you would set:

column.For(x => x.EventDate).HeaderText("Event Date").DataType("date").Format("dateTime").Template("{{if new Date(${EventDate}) < new Date()}}" +
                                         "<div style='background-color:yellow'>${EventDate}</div>" +
                                         "{{elseif new Date(${EventDate}) > new Date()}}" +
                                         "<div style='background-color:green'> ${EventDate}</div" +
                                         "{{/if}}");

Hello Michel,

Thank you for the update. The reason why your cells are empty is the EventDate is being conversted to a string and you are trying to compare a string to a date. So you will have to wrap your EventData in a new Date:

        "{{if new Date(${EventDate}) < new Date()}}" +
               "<div style='background-color:yellow'>${EventDate}</div>" +
               "{{elseif new Date(${EventDate}) > new Date()}}" +
               "<div style='background-color:green'> ${EventDate}</div" +
               "{{/if}}"
