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);

});

Update:

Due to the way that the allChildrenWidgets() method works, it was necessary to add a bit of code to retrieve the correct item from the array.

$("#gridContracts").on("ighierarchicalgridrowexpanding", function (evt, ui)

{    

    var parentRow = ui.parentrow;    

    var parentRowId = parentRow.attr("data-id");    

    var simId = $("#gridContracts").igGrid("getCellValue", parentRowId, "Simulation_id");    

    // get primary key value from parent row

    var pk = $("#gridContracts").igGrid("getCellValue", parentRowId, "Contract_id");    

    var childGrids = ui.owner.allChildrenWidgets();

    // loop thru array of allChildrenWidgets()

    for (var i = 0; i < childGrids.length; i++)    

    {        

        // compare pk to fk of first row in each grid item

        if (childGrids[i].getCellValue(childGrids[i].rows(0).attr("data-id"), "Contract_id") == pk)        

        {            

             childGrids[i].setColumnTemplate(childGrids[i].options.columns[0].key, "<a href=\"targetpage.aspx?s_id=" + sim_Id + "&v_id=${Version_id}\" target=\"_self\">Details</a>", true);        

             break;

        }    

    }

});

Hello lwoodell ,

I am new to iggrid.

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) {

var parentRow = args.parentrow;    

    var parentRowId = parentRow.attr("data-id");

    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:

var parentRowId = parentRow.attr("data-id");

Thanks

Hello lwoodell,

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).
