How to disable the CheckBox in the GridView Header?

Question

GridView

In this GridView, I want to disable all the CheckBox in the GridView during the View Mode. I can disable the GridView Row cells like

foreach (GridViewRow GVR in gvPODetails.Rows)
    {
        GVR.Cells[1].Enabled =          
        GVR.Cells[11].Enabled = false;
    }

But I dont know how to disable the checkbox in the HeaderTemplate of the Template Field. How to do this?

You may set checkbox Enabled property to false or explain what do you want to achieve. — IUnknown

Recipe:

Handle OnRowDataBound on your GridView
Detect whether you are iterating through the header by using e.Row.RowType == DataControlRowType.Header and get a reference to your checkbox control using e.Row.FindControl(checkBoxID)
Set the Enabled property to False

Try this code:

void GridView_RowDataBound(Object sender, GridViewRowEventArgs e) 
{
    if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header ) {
        MyClass myObj = (myObj)e.Row.DataItem;
        CheckBox cb = (CheckBox)e.Row.FindControl("myCheckBox");
        cb.Enabled=false;        
    }
}

Your code disable all checkboxes as you've written if (e.Row.RowType == DataControlRowType.DataRow || e.Row.RowType == DataControlRowType.Header ) but the asker wanted to disable the checkbox in the header so it should be as : if (e.Row.RowType == DataControlRowType.Header ) and then disable here. Thanks for your time.
