Hello,

Thank you the question regarding WebGrid.

To make the row or cell became doesn’t editable (read-only), you could use SetForceNoEdit() JavaScript method.

I made a simple runnable sample to show how-to implement the SetForceNoEdit() method.
I bind the WebGrid to Access Data Source (Northwind.mdb database & Products table).

In use the SetForceNoEdit() method in OnRowSelect client side event.
I make the row / data that already Discontinued to become read-only.
Here’s the example snippet code how I implement the SetForceNoEdit() method:

function WebGrid1_OnRowSelect(controlId, tblName, rowIndex, rowEl) {    var WebGrid1 = ISGetObject(controlId);
    var rowObj = WebGrid1.RootTable.ToRowObject(rowEl);
    var Cells = rowObj.GetCells();
    if (Cells[3].Value == true && rowObj.ForceNoEdit == false) {
        rowObj.SetForceNoEdit(true);
        Cells[3].SetForceNoEdit(true); // To make the Check Box become read-only
    }
}

I also attached the sample, so that you can see the result as well.

Thank you.

Regards,
Hans.
