Is it possible to reference parent row data in the column template of a child row?
I have tried, for example: ${parent.ColumnKey}, but this doesn't work.
Further, the grid is bound to a DataSet of (2) related DataTables.
Hello lwoodell,
It depends on what exactly you're aiming to achieve. From the grid API you can get more information about the events where is possible to access the parent row: http://help.infragistics.com/jQuery/2014.2/ui.ighierarchicalgrid#events Could you please explain me in more details what is your purpose in order to be more helpful for you?
Looking forward to your response.

Tsanna,
Using the RowExpanding event of the igHierarchicalGrid, I was able to get the desired result. (See below)
If there is a better or more efficient way to achieve this, please let me know.
$("#gridContracts").on("ighierarchicalgridrowexpanding", function (evt, ui)
{
var parentRow = ui.parentrow;
var parentRowId = parentRow.attr("data-id");
// get the value from the parent row cell by column key
var simId = $("#gridContracts").igGrid("getCellValue", parentRowId, "Simulation_id");
// get a the child grid object
var childGrid = ui.owner.allChildrenWidgets()[0];
// set the column template
childGrid.setColumnTemplate(childGrid.options.columns[0].key, "<a href=\"targetpage.aspx?s_id=" + simId + "&v_id=${Version_id}\" target=\"_self\">Details</a>", true);
});
Hello Tsanna,
I am new to iggrid.
I checked the sample code for using iggrid as parent-child relationship.
But I haven`t got the right solution yet.
I want to use in the following way:
1. get data from server for parent grid
2. when i click the plus icon of the parent row, I have to use some of the parent`s row data as parameter to load the server data for child grid
For now, i can load data only for parent grid. And I am using rowexpanding event to load the data for child.
But, I don`t know :
1.how to get the parent row data by that event.
2 how to set the data source that I searched for child grid.
Thanks for your help!
Thank you for your raply.
I haven`t got the solution yet.
Thanks
I think the "data-id" row attribute is generated automatically when a primary key is assigned to the row, and correlates to the value of the PK.
In my example, I was dealing with a hierarchical grid bound to a dataset of related tables (PK/FK relation).
Hello lwoodell ,
I can`t call the ighierarchicalgridrowexpanding event when i click the plus icon of the parent row. So, I used the rowExpanding event as below:
rowExpanding : function(e, args) {
rowExpanding :
function
(e, args) {
var parentRow = args.parentrow;
args
var pk = $("#gridId").igGrid("getCellValue", parentRowId, "ColumnKey");
}
Then, I got the following error:
Cannot read property dataType of null in infragistics.lob.js
May I know what is the data-id in following line:
