Hello Aravind,

You can change the state of the checkbox using client side code – _setCheckState using 1 – checked and 0 – unchecked as parameter.

var grid = ig_controls["WebDataGrid1"];
var cell = grid.get_rows().get_row(row_index).get_cellByColumnKey("Checkbox");
var newCheckState = cell._getCheckState() === 1 ? 0 : 1;
cell._setCheckState(newCheckState);

Let me know if you have any questions with this matter.

Hello Aravind,

About your first question, you can disable a checkbox using CellValueChanging not EnteringEditMode event.   

                       
...

function WebDataGrid1_Editing_CellValueChanging(sender, eventArgs) {
    let currentCell = eventArgs.get_cell();
    if (currentCell.get_column().get_key() == "Checkbox") {
       var index = currentCell.get_row().get_index();
           if (index == "0")
               eventArgs.set_cancel(true);
        }
     }

About your second question, it is best to modify your data source checkbox value.

About your third question, you can disable the editing of the entire column setting it as ReadOnly:

EditingColumnSetting settings = new EditingColumnSetting()
{
    ColumnKey = "Checkbox",
    ReadOnly = true
};
WebDataGrid1.Behaviors.EditingCore.Behaviors.CellEditing.ColumnSettings.Add(settings);

Let me know if you have any questions with this matter.
