Question

The code in this event is repeated exactly in two other event handlers. How do I put the repeated code into a method and call that method from the event handlers so I only have to maintain it in one place? I’m not sure how to pass the event args to the calling method.

 protected void gvDocAssoc_RowDataBound(object sender, GridViewRowEventArgs e)
        {



            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DETAIL_TYPE_DESC")) == "Transcript") && 
                    (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == ""))
                {
                    e.Row.BackColor = System.Drawing.Color.Red;
                }
                if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DETAIL_TYPE_DESC")) == "Certified Diploma") &&
                    (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == ""))
                {
                    e.Row.BackColor = System.Drawing.Color.Red;
                }

                if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DOC_TYPE_DESC")) == "Post Graduate conditions") &&
                    (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == ""))

                {
                    e.Row.BackColor = System.Drawing.Color.Red;
                }

            }


        }

You can assign the same handler to more than one object that is raising events. For example,

myGridView1.RowDataBound += gvDocAssoc_RowDataBound;
myGridView2.RowDataBound += gvDocAssoc_RowDataBound;
myGridView3.RowDataBound += gvDocAssoc_RowDataBound;

Alternately, just create a method with the same signature as the event handler, and pass in the same arguments:

private void RepeatedCodeHandler(object sender, GridRowEventArgs e)
{
   // Repeated code
}

and from your three handlers that are repeating code,

protected void gvDocAssoc_RowDataBound(object sender, GridViewRowEventArgs e)
{
     // Call method
     RepeatedCodeHandler(sender, e);
}
