Solution 1

Before using productsTable[0] check if there are rows in product table.

C#

if (productsTable != null && productsTable.Rows.Count > 0 && (row1 = (DataRowView)productsTable[0]).ToString()!="0")

I would agree that checking the Row Count can prevent the issue you are getting. You could actually rewrite your code to this:

C#

protected void ddlAllEngineerSolver_SelectedIndexChanged(object sender, EventArgs e){
        DataView productsTable = (DataView)
        SqlDataSourceAssignedComplains.Select(DataSourceSelectArguments.Empty);
        productsTable.RowFilter = string.Format("EngName = '{0}'",
            ddlAllEngineerSolver.SelectedItem);

 	    DataTable dtResult = productsTable.ToTable();
        if (dtResult.Rows.Count > 0)
        {
            GridView1.DataSource = dtResult
            GridView1.DataBind();
        }
	    else{
		         //display no result found
	    }   
}
