expand row throws error after updating every row in grid with updateRow

[Mark Mecinski]

Hi,

Please see the error below that occurs when attempting to expand a row after updating the TreeGrid with the following code.

We have a grandparent, parent, child structure in our treegrid - in other words, a 3 dimensional structure. In the code below, we are updating the parent and child for the selected (checked) records.

Pagination or virtualization cannot be used for our requirement.

The error is temporary.  Depending on the size of the grid, after a few seconds to a minute after updating rows with code below, expanding any row works fine.

    this.treeGridEditSettings = {

      allowEditing: true,

      allowAdding: true,

      allowDeleting: true,

      mode: "Row"

    };

  fnIssuer2(issuerPctValue: string) {

    var index = this.treegridpropsedorders.getCheckedRowIndexes()

    let checkedRecords:any=this.treegridpropsedorders.getCheckedRecords();

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

      if (checkedRecords[i]["groupaccountlevel"] == "P") {

        this.treegridpropsedorders.updateRow(index[i], { pct_issuer_display: 2.2, feedstatus: "C" });

        var children = checkedRecords[i]

        if (children.hasChildRecords) {

          for (var j = 0; j < children.childRecords.length; j++) {

            let treePrimaryPK = +children.childRecords[j]["groupAcctPK"];

            if (children.childRecords[j]["qty_ordered"] != 0)

              this.treegridpropsedorders.updateRow(treePrimaryPK - 1, { pct_issuer: 2.2, typeofchange: "issuer", feedstatus: "C", "priority": 1, "rebalprice": 3.3, heldprioritizedflag: "N" });

            else

              this.treegridpropsedorders.updateRow(treePrimaryPK - 1, { pct_issuer: 2.2, typeofchange: "issuer", feedstatus: "C", "priority": 1, "rebalprice": 3.3, heldprioritizedflag: "Y" });

          }

        }

      }

    }

  }
